ARTICLE SUMMARY:

Mosquito control programs use a range of strategies to manage mosquito populations and reduce nuisance and disease risks. This article breaks down six commonly confused sets of mosquito control terms and explains how each concept fits into an effective management program.

Even among people who work closely with mosquito control programs, some of the most common vector control terms are frequently misunderstood. Whether you’re a community leader, public health official, or local citizen, understanding common terms and their distinctions can lead to better communication, more informed mosquito control decisions, and more realistic expectations.

Below, we break down six pairs of commonly confused mosquito control terms. While they may sound similar, these concepts describe very different mosquito control strategies, goals, and outcomes.

1. Integrated Mosquito Management (IMM) vs. Mosquito Spraying

One of the biggest misconceptions is that mosquito control simply means spraying insecticides. In reality, spraying is only one tool within a much larger strategy known as Integrated Mosquito Management (IMM).

What Is Integrated Mosquito Management?

Women_checking_dip_cup_vdci_truck

Integrated Mosquito Management is a science-based approach to mosquito control that uses surveillance data, established action thresholds, environmental considerations, and multiple control methods to manage mosquito populations. IMM targets mosquitoes at each life cycle stage.

A comprehensive IMM program may include:

  • Surveillance to monitor mosquito populations and activity
  • Source reduction to eliminate breeding sites
  • Disease testing to assess public health risks
  • Insecticide resistance monitoring to ensure treatment effectiveness
  • Larval control measures to disrupt mosquito development before they mature
  • Adult control measures when populations reach threshold levels
  • Public education to empower community participation and personal protection

The goal is to achieve effective mosquito control while minimizing unnecessary pesticide applications.

What Is Mosquito Spraying?

Mosquito spraying refers specifically to applying insecticides—usually adulticides—to reduce adult mosquito populations. Spraying can be an important mosquito control tool, but spraying alone is not the same as Integrated Mosquito Management.

Spraying alone doesn’t:

  • Eliminate mosquito breeding sites
  • Identify where or when mosquito populations are increasing
  • Replace mosquito surveillance
  • Address insecticide resistance
  • Evaluate whether treatment achieved the desired result

KEY TAKEAWAY:

Spraying is just one tool in Integrated Mosquito Management (IMM). Effective mosquito control combines surveillance, prevention, and targeted treatments to manage mosquitoes at every life stage while minimizing unnecessary insecticide use.

2. Larvicide vs. Adulticide

Larvicides and adulticides are both insecticides—products that are designed to kill specific insects. However, they target different life cycle stages.

What Is a Larvicide?

Larvicides used in mosquito control are used to target mosquitoes during their larval stage, before they become biting adults. Mosquito larvae develop in standing water, so larvicides are typically applied to aquatic habitats where mosquitoes are known to breed, such as stormwater ponds and ditches.

Insecticides may be applied using:

  • Backpack applicators
  • Truck- or ATV-mounted sprayers
  • Commercial drone 
  • Turbo-powered single-engine helicopter 
  • Fixed-wing single-engine aircraft

What Is an Adulticide?

In mosquito control, an adulticide is a product that targets flying adult mosquitoes after they have emerged from their aquatic habitats. Adulticides are typically applied with Ultra-Low Volume (ULV) equipment that disperses insecticide as fine aerosol droplets. The droplets remain suspended in the air briefly, allowing adult mosquitoes to contact the insecticide while flying.

Adulticides may be applied using:

  • Backpack applicators
  • Truck- or ATV-mounted sprayers
  • Twin-engine aircraft

Adulticiding is generally used when surveillance indicates that mosquito populations have exceeded established action thresholds or when there is an elevated public health concern, such as an increased risk of disease transmission.

Which Is Better: Larvicide or Adulticide?

Neither is inherently better; they serve different purposes. Larviciding and adulticiding are vital mosquito control tools, but they shouldn’t be viewed as interchangeable. They’re most effective when used strategically as part of an integrated mosquito management plan.

KEY TAKEAWAY:

Larvicides target mosquitoes before they become biting adults, while adulticides target flying adult mosquitoes. Both are important tools that can be used strategically within an integrated mosquito management program.

3. Insecticide Resistance vs. Tolerance

Insecticide resistance and tolerance are sometimes used interchangeably, but they describe different biological processes.

What Is Insecticide Resistance?

Insecticide resistance is a genetic change that allows some mosquitoes to survive exposure to an insecticide that would normally control them.

Resistance develops over generations. When mosquitoes survive insecticide exposure and reproduce, the traits associated with resistance can become more common within the population.

Insecticide resistance is:

  • Genetic
  • Heritable
  • An evolving population-level concern

What Is Tolerance?

Tolerance refers to an individual mosquito’s natural ability to withstand insecticide exposure without necessarily involving an inherited genetic change.

Tolerance:

  • Is not necessarily inherited
  • May vary among individual mosquitoes
  • Does not mean an entire mosquito population will become resistant

Why Understanding Mosquito Insecticide Resistance vs. Tolerance Matters

Resistance can affect the long-term effectiveness of mosquito control products. That’s why mosquito management programs may use strategies such as:

  • Conducting insecticide resistance testing
  • Rotating insecticide classes
  • Using multiple mosquito control methods

Preventing insecticide resistance helps preserve the effectiveness of available mosquito control tools over time.

KEY TAKEAWAY:

Mosquitoes can develop insecticide resistance through genetic changes that are passed from one generation to the next. Resistance management can include testing mosquito populations, rotating insecticide classes, and using multiple control strategies.

4. Mosquito Surveillance vs. Monitoring

Surveillance and monitoring both involve collecting information, but they answer different questions.

What Is Mosquito Surveillance?

Mosquito surveillance is the process of gathering information about mosquito populations and disease activity to inform mosquito control decisions.

Surveillance activities may include:

  • Setting mosquito traps
  • Identifying mosquito species
  • Counting mosquito abundance
  • Testing mosquitoes for viruses or other pathogens
  • Mapping mosquito breeding locations over time
  • Tracking seasonal population trends

Mosquito surveillance can answer questions such as:

  • Which mosquito species are present?
  • How many mosquitoes are present?
  • Are disease-carrying mosquito populations increasing?
  • Have established action thresholds been met?

This information helps mosquito management professionals determine whether intervention is necessary.

What Is Mosquito Control Monitoring?

Monitoring helps mosquito control programs determine whether treatments achieved their intended results and whether adjustments are needed.

Monitoring may assess:

  • Treatment coverage
  • Larvicide and adulticide effectiveness
  • Changes in mosquito populations
  • Long-term impact

KEY TAKEAWAY:

Surveillance collects information about mosquito populations and disease activity to help determine whether control measures are needed. Monitoring evaluates how effective those control measures were after they were implemented.

5. Mosquito Source Reduction vs. Treatment

Not every mosquito problem requires a pesticide application. Often, one of the most effective ways to reduce mosquitoes is to eliminate or modify the places where they breed.

What Is Source Reduction?

Source reduction is the process of removing or modifying mosquito breeding habitats so mosquitoes have fewer places to lay eggs and develop. Source reduction addresses mosquito production at its source rather than treating mosquitoes after they have developed.

Examples of source reduction include:

  • Removing standing water
  • Cleaning clogged gutters
  • Emptying water-holding containers
  • Improving drainage
  • Managing stormwater systems
  • Eliminating discarded tires and debris

What Is A Mosquito Treatment?

Mosquito treatment involves applying EPA approved products designed to control mosquitoes, including larvicides, which target mosquitoes in aquatic habitats, and adulticides, which target flying adult mosquitoes. Treatments are selected based on factors such as surveillance data, environmental conditions, mosquito species, and public health needs.

Why Do Both Mosquito Source Reduction and Treatment Matter?

Source reduction is often the first line of defense because it addresses the habitat that allows mosquitoes to reproduce.

However, not every breeding site can be eliminated. Wetlands, retention ponds, floodwater habitats, stormwater systems, and other permanent or difficult-to-modify water bodies can continue to produce mosquitoes. In these situations, targeted larviciding—and, when necessary, adulticiding—can provide additional control.

The most effective mosquito management programs combine habitat reduction with targeted treatments rather than relying on pesticides alone.

KEY TAKEAWAY:

Source reduction is the process of eliminating or modifying mosquito breeding habitats to prevent mosquitoes from developing. Mosquito treatment involves applying products designed to control mosquitoes.

6. Mosquito Suppression vs. Eradication

Perhaps the biggest misconception in mosquito control is the belief that mosquitoes can be entirely eliminated. However, this is not realistic. 

More than 3,500 mosquito species exist worldwide, and many occupy extensive natural habitats. Rather than attempting to eliminate every mosquito, vector control programs focus resources on reducing populations of mosquito species that pose the greatest nuisance or public health risks.

What Is Mosquito Suppression?

Mosquito suppression means reducing mosquito populations to levels that help minimize nuisance biting and the risk of mosquito-borne disease. Suppression is the goal of most mosquito control programs.

What Is Mosquito Eradication?

Mosquito eradication means permanently eliminating an entire mosquito species from a defined geographic area. For mosquitoes, complete eradication is generally not a realistic objective.

Instead, modern vector control programs focus on mosquito suppression —  reducing mosquito populations and associated risks to manageable levels while considering environmental stewardship.

KEY TAKEAWAY:

The realistic objective of modern vector control is mosquito suppression—reducing mosquito populations to minimize nuisance biting and disease risk—rather than permanently eliminating mosquitoes from an area.

Protect Public Health with A Strong Mosquito Management Program

While mosquito control terminology can be intricate, clear definitions are essential for setting realistic expectations with citizens and building effective and realistic mosquito control programs. At its core, the long-term goal is simple – to protect public health.

Forecasting the Future: Integrating Weather and Climate Models into Your Emergency Response Plan

Planning for hurricanes and other major weather events is an important part of emergency preparedness. While storms can cause widespread property damage, utility outages, and transportation disruptions, they can also cause spikes in mosquito populations, which may overwhelm displaced citizens or emergency response workers. By understanding and anticipating the ways climate and weather can influence mosquito populations, you can build a more robust emergency response plan.

How Temperature and Precipitation Affect Mosquito Populations

Temperature and precipitation are two key environmental factors that influence mosquito activity, breeding, and population levels.

Changing Temperatures

Mosquitoes thrive in warm temperatures, with the ideal range for adult mosquitoes being from 75°F to 90°F. Paired with high humidity, these conditions facilitate the rapid breeding and development of mosquitoes, and their feeding behavior is most aggressive at temperatures within this range. At temperatures below 50°F or above 90°F, mosquito activity sharply declines. 

With average temperatures increasing in many parts of North America, ideal conditions for mosquitoes can become more common. Higher average temperatures and milder winters can increase the survivability of mosquitoes and their eggs, allowing established mosquito populations to broaden their range. 

This can occur in native mosquito species, which may adapt to newer, more favorable conditions, as well as in invasive species like Aedes albopictus, which have been introduced from tropical and subtropical regions. As conditions change over time, mosquito species may survive higher latitudes or elevations at which they were not previously established.

The Effects of Rainfall

When a tropical storm or a hurricane affects an area, heavy precipitation can cause a substantial amount of standing water in a short time. Previously dry, low-lying areas can become inundated, greatly expanding the availability of mosquito breeding sites. Humidity levels often increase after a storm as well.

However, storms can also overwhelm existing mosquito breeding sites by rapidly flushing out existing water, causing an overflow, which may flood out or drown existing mosquito habitats. One area can be affected by a storm differently from another, making it crucial to plan for the specific features and conditions present.

Making a Mosquito Emergency Response Plan

In situations where favorable temperature and humidity levels coincide with a dramatic increase in standing water after a storm, mosquito populations can rapidly increase. 

When mosquito populations rapidly increase near human population centers, they can further stress displaced citizens who may be dealing with property loss or other adverse effects of the storm. These dramatic increases in mosquito numbers may also make emergency response work more difficult to conduct, as workers spending long periods outdoors to address downed power lines, roadway debris, or other issues may be forced to constantly fight off swarms of biting mosquitoes.

Because of this, it is crucial to plan ahead and build an emergency response plan that makes appropriate considerations for mosquito management.

Considering Weather and Climate Models

Large climate phenomena like El Niño can affect hurricane seasons, and this information is often factored into yearly forecasts. 

By combining information from weather forecasts with pre-storm mosquito monitoring and surveillance, mosquito management professionals and emergency response planners can prepare for potential population outbreaks. If the data shows significant risk of an outbreak, they will take steps to rapidly curb mosquito population levels so that recovery efforts can continue unimpeded and displaced citizens won’t deal with added stress from abundant mosquitoes.

How VDCI Can Help

Mosquito management professionals at VDCI can assist with preparing an emergency response plan and taking appropriate measures pre-storm. 

In addition to monitoring and surveillance, VDCI can take proactive control measures such as pre-staging chemical or biological treatments in regions where a hurricane is likely to make landfall.  This ensures there are adequate tools available even if roads and bridges are severely damaged.  

Experts at VDCI will also take action post-storm to monitor changes in mosquito populations and may run aerial missions to aggressively control mosquito numbers. Results will be closely monitored and communicated to emergency response planners and other local stakeholders. 

Effective emergency response is complex, but with careful planning and collaboration, you can be well-prepared for hurricanes and other major weather events. 

Key Takeways

  • Weather and climate patterns can significantly influence mosquito populations before and after major storms.
  • Heavy rainfall and standing water can create ideal mosquito breeding conditions following hurricanes or major flooding events.
  • Pre-storm mosquito surveillance helps emergency planners anticipate population surges and target mosquito control efforts.
  • Emergency response plans should include mosquito management strategies to protect workers and the public.
  • Partnering with mosquito management professionals before and after storms can reduce mosquito populations and support effective emergency response.

Understanding Mosquito Ecology: Their Lifespan, Environmental Factors, and Effective Mosquito Management

Mosquitoes are a diverse family of flies, with over 3,500 species worldwide. They can be found nearly everywhere in the world, from equatorial forests to the Arctic. Although the adults are notable for feeding on the blood of humans and other animals, it is only the female mosquitoes of some species that do so. Females of these species utilize blood to obtain proteins necessary for egg development. 

Due to their widespread distribution, adaptability, and status as disease vectors, mosquitoes can pose significant health risks to people around the world.

The Mosquito Lifecycle​

Like other flies, mosquitoes undergo complete metamorphosis that includes four life stages: egg, larva, pupa, and adult.

Egg Stage

Female mosquitoes lay their eggs on the surface of standing water. While mosquitoes cannot breed in running water, the sources of stagnant water they use can vary dramatically by species. Common breeding sources include:

  • Ponds
  • Drainage ditches
  • Tree holes
  • Plastic buckets
  • Other natural or artificial containers

Where Do Mosquitoes Lay Their Eggs?

Mosquitoes have adapted various ovipositing behaviors, allowing them to succeed in a range of environments.

 

Culex mosquitoes lay their eggs in clusters of floating rafts, while Aedes mosquitoes lay single eggs on vegetation or another natural substrate just above the waterline. The eggs of Anopheles mosquitoes feature a pontoon-like structure that allows them to float directly on the water surface. Toxorhynchites mosquitoes can oviposit while airborne and simply flick their eggs into water-filled tree holes or artificial containers.

Larval and Pupal Stages

Mosquito eggs hatch into fully aquatic larvae, which typically feed on algae, bacteria, and other microscopic organisms. Some mosquito larvae, such as Toxorhynchites, are predatory and will feed on other mosquito larvae, making them a natural biological control for other mosquitoes. 

In turn, mosquito larvae can serve as a food source for:

  • Dragonflies
  • Fish
  • Amphibians
  • Waterfowl

Surviving larvae eventually develop into pupae; the mosquito pupa is unusual among insect pupae in that it retains the ability to move and will swim vigorously to avoid predation. When it is not moving, the pupa typically hangs down from the surface of the water, breathing oxygen from two air tubes called trumpets.

Adult Mosquitoes

Adult mosquitoes emerge from the pupa at the water’s surface and take flight. Their flight range can also vary dramatically by species. Container species like Aedes albopictus may fly only about 50 meters from their breeding sites, while many salt marsh species are known to fly more than 30 miles.

When Do Mosquitoes Go Away at Night?

Adult male and female mosquitoes of all species feed primarily on the nectar of flowers. Because of this, they are pollinators of some plants. Adult mosquitoes are also an important food source for animals such as dragonflies, small birds, and spiders. 

Because female mosquitoes feed on blood, many of them vector pathogens like viruses, protozoans, and nematodes, which can cause a wide range of infectious diseases. A few days after feeding, females will seek appropriate breeding sites in which to oviposit their eggs.

Environmental Factors That Influence Mosquito Populations

Weather can have a major influence on mosquito populations.

Droughts

In times of drought, freshwater sources often dry up and become less available for breeding sites. Many animals, such as birds, will also congregate in greater densities at these water sources. The resulting proximity can cause a higher rate of bites and may increase the spread of mosquito-borne diseases since there is an increased rate of transmission between mosquito vectors and their avian hosts.

Heavy Rainfall and Flooding

At the opposite end of the spectrum, heavy rains and flooding can lead to a sharp increase in the mosquito population, thereby potentially increasing disease risk.

While many mosquitoes breed in permanent water sources, others, known as floodwater mosquitoes, breed in temporary water sources such as drainage ditches and floodplains. These mosquito species have eggs that are adapted to temporary water sources, allowing them to remain dormant during dry periods for an extended period of time. Once a heavy rain event occurs, they will immediately hatch, thus completing their lifecycle. After a flooding event, many such eggs will hatch simultaneously in one area.

Temperature, Humidity, and Habitat

As with many insects, mosquitoes are prone to dehydration and prefer environments that are warm and humid. Warmer temperatures often facilitate increased larval development. Mosquitoes are not typically active at temperatures below 50°F or relative humidity below 30%. In addition to standing water sources, optimal habitat for all mosquitoes will include vegetation thick enough to shelter adults from wind and sunlight during the day.

Mosquito Surveillance & Abatement

Mosquito management professionals pay close attention to the environmental and ecological factors that may affect mosquito populations. By monitoring weather, temperature, and humidity conditions, experts can anticipate changes in mosquito populations and behavior, allowing them to create models to predict disease outbreaks.

Prior to a major rainfall event, they may take action to curb larval populations, or they may closely monitor breeding site locations and disease levels in adults during a drought. 

Mosquito management professionals can utilize chemical treatments as well as biological control agents to control adult and larval mosquitoes. By introducing organisms like the mosquito fish (Gambusia affinis) or the bacterium Bti (Bacillus thuringiensis israelensis), mosquito larvae can be effectively managed without harming other organisms in the aquatic environment.

As we can see, there are a number of factors at work when it comes to controlling mosquito populations. This multifaceted approach is known as Integrated Mosquito Management, the most effective and environmentally responsible way to control mosquito populations.

Mosquito abatement is about always staying two steps ahead of changes in mosquito populations and behavior. That’s why careful surveillance and a thorough understanding of relevant environmental and ecological conditions are absolutely crucial for an effective abatement program.

Key Takeaways

  • Mosquitoes undergo complete metamorphosis through their four-stage lifespan: egg, larval, pupal, and adult.
  • Most mosquitoes remain relatively close to the water source where they hatch.
  • Weather patterns, flooding, drought, temperature, and humidity all influence mosquito populations.
  • Integrated Mosquito Management relies on surveillance, environmental monitoring, various control strategies, and public education to reduce mosquito populations effectively.

Transparency and Public Trust: Best Practices for Communicating About Mosquito Control and Product Safety

The Evolution of Modern Mosquito Control

Over the past century, mosquito control has evolved into a highly regulated, science-driven field. Modern Integrated Mosquito Management (IMM) programs are characterized by their emphasis on safety and precision. Today, mosquito control experts prioritize applying the right insecticide products at the right times and in the right places, in the right amounts, and only when surveillance data indicates it is necessary. 

Yet, public education has rarely kept up. Historical missteps, environmental failures, misinformation, and limited understanding of insecticide products have fostered widespread skepticism about insecticide use. Without community buy-in, even the most well-designed IMM programs can fall short of their goals.

Public Trust: The Industry’s Greatest Challenge

Since 1979, the American Mosquito Control Association (AMCA) has recognized public education as a key pillar of IMM programs—equally important to surveillance and disease testing, larval mosquito control, and adult mosquito control. However, only a small fraction of agency budgets are set aside for education, and, as of 2020, the AMCA identified a lack of public support as the industry’s greatest challenge. 

Building Public Trust Through Communication

Copy of Government-partner-12

Effective IMM programs rely on public confidence, especially when mosquito control interventions involve visible actions such as spraying. Impressive academic degrees and titles do not automatically generate trust among residents. Instead, trust is built on three fundamental principles:

  • Communication
  • Empathy
  • Consistency

Acting on these principles doesn’t mean diverging from science-based decisions. Rather, it builds support for those decisions through: 

  • Listening to public health concerns before responding with data
  • Acknowledging fear or uncertainty about insecticides without dismissing it
  • Anticipating questions before they escalate
  • Providing clear, ample information and educational opportunities
  • Tailoring messaging to different audiences and contexts

The key to public education is being proactive with these initiatives. The least effective time to build public trust is when initiating city mosquito control actions or, even worse, during a natural disaster, disease outbreak, or other public health emergency. Urgency can cause communication gaps, and heightened emotions can make the public less receptive. 

When education and open dialogue are established well in advance, community members can feel a greater sense of safety and certainty when challenges arise. Best practices include:

  • Clearly explaining program goals, action thresholds, and safety measures
  • Coordinating messaging with public health departments, local media, schools, and community organizations  
  • Maintaining consistent messaging across communication channels
  • Developing pre-approved communication templates for routine control efforts and emergencies

Gaps in Public Education About Mosquito Control

Despite the AMCA’s emphasis on education, many community outreach approaches have remained static. Traditional mediums, such as brochures, presentations, and press releases, have not evolved sufficiently, and opportunities for deeper engagement (such as facility tours or ongoing media spotlights) have broadly declined.

Encouragingly, the organizations responsible for education have started to shift. More agencies are using dedicated communications professionals, rather than relying solely on technical experts. That said, most programs still struggle to gauge whether educational efforts are successful. This is often determined by social media impressions or event turnout, rather than measurable changes in overall public sentiment. 

While personal protection tips are widely communicated, far less public education focuses on core topics such as mosquito surveillance, disease testing, larval and adult control, and insecticide resistance. In fact, fear of public backlash has led some mosquito control programs to avoid discussing insecticide use entirely. 

The reality is, mosquito-borne diseases kill more than one million people worldwide each year. Insecticides are a vital tool to reduce public health risks during periods of elevated mosquito activity.

Setting Expectations for Mosquito Control Programs

Residents want to understand what products are being used, how those products interact with the environment, where and when applications occur, and most importantly, why those actions are necessary. Covering the following topics can help set expectations around what mosquito control activities may look like:

The Goals of Integrated Mosquito Management (IMM)

IMM programs are not focused on eliminating all mosquitoes—they’re designed to keep mosquito populations at manageable levels and minimize the need for chemical intervention. Insecticide applications are never routine. Mosquito surveillance, disease monitoring, and data analysis guide every decision regarding when and where to apply insecticides. 

Following Action Thresholds

Insecticides are applied only when defined action thresholds are met and only in locations where data indicates a clear need. An action threshold is a predefined level of mosquito abundance, activity, or disease risk that triggers a carefully planned intervention. Timing, products, and application methods are tailored to target specific mosquito species while minimizing impacts on people, animals, and non-target insects. 

How Insecticide Applications Work

Our program managers evaluate a wide range of environmental and site-specific factors when determining which products are best suited for each treatment area. These considerations include vegetative cover, organic content in the water, the presence of beneficial biological control agents, and weather-related influences such as heavy rainfall or flooding that may dilute or displace treatments. By carefully assessing these variables, we ensure that each application is both effective and environmentally responsible.

VDCI utilizes only EPA-registered products that are specifically labeled for public health mosquito control, ensuring both safety and regulatory compliance. All applications are conducted by licensed professionals who are trained to apply treatments accurately and responsibly. To effectively manage mosquito populations at every stage of their life cycle, we employ a combination of strategies, including larviciding, which targets mosquitoes in their aquatic larval stage before they develop into biting adults and adulticiding, which focuses on reducing populations of active, flying mosquitoes. In addition, we prioritize the rotation of insecticide classes to help minimize the risk of resistance development and maintain long-term effectiveness.

Types of Mosquito Control Equipment

The key to safe insecticide applications is Ultra-Low Volume (ULV) spray equipment, which is designed to disperse fine aerosol insecticide droplets that kill flying mosquitoes on contact. Typically, less than one ounce of product is used per acre, with droplets roughly half the width of a human hair. This equates to about two tablespoons applied to an area the size of a football field. 

Residents are most likely to see truck-mounted and backpack sprayers, but drones and aerial solutions can also complement ground-based efforts by providing uniform coverage over large, inaccessible, or hazardous areas.

Preventing Insecticide Resistance

In addition to minimizing environmental impacts, experts strive to keep insecticide use to a minimum to prevent insecticide resistance. If mosquitoes are exposed to a product too frequently or in excessive amounts, the product can lose effectiveness over time. 

As part of surveillance efforts, scientists regularly test for insecticide resistance in a lab and take necessary steps, such as modifying dosages or rotating products, if resistance is detected.

The Role of Community Participation

Residents play a direct role in mosquito prevention by eliminating breeding sites on their own properties. When the public understands how decisions are made and how their actions contribute to success, mosquito management can be viewed as a shared responsibility.

Community Trust Strengthens Mosquito Control Programs

Partnering with a company that specializes in IMM allows leaders to focus on public health priorities rather than day-to-day complaints or mosquito-related concerns. VDCI offers a range of support, from developing educational campaigns and presenting at public forums to setting up communication channels and emergency response messaging.

Engaging communities early, explaining decisions clearly, and demonstrating accountability helps ensure that when mosquito control is required, public support is already in place.

Mosquito Threats: The True Cost of Inaction

The Financial Repercussions of Not Controlling Mosquitoes

When communities consider establishing an Integrated Mosquito Management (IMM) program, budget is often a top concern. But focusing only on costs can overshadow a much bigger issue – the price of doing nothing. When mosquito populations aren’t properly managed, they can trigger a chain reaction that affects public health, local economies, and everyday quality of life. 

The true cost of mosquito control inaction often appears in ways that are more challenging and expensive to resolve:

  • Increased healthcare costs associated with disease outbreaks
  • Veterinary expenses tied to diseases affecting pets and livestock
  • Lost productivity from missed workdays and disability
  • Tourism impacts driven by travel concerns and perceived health risks
  • Property value decline linked to nuisance mosquito populations

Mosquito Management Is an Investment

There is no denying that effective city mosquito control programs require judicious funding, and budgets can vary widely depending on geography, community size, and disease risk.

For example:

  • Miami-Dade County, Florida, invests roughly $16.7 million annually to serve a population of approximately 2.7 million residents.

  • The Central Massachusetts Mosquito Control Project operates on about $2.3 million per year to protect 42 towns and nearly one million people.

  • Smaller municipalities also make notable investments. For instance, Bentonville, Arkansas, allocates around $500,000 annually for surveillance and control efforts.

At first glance, these numbers may seem high. But when compared to the costs of disease outbreaks, emergency response, and lost economic activity, mosquito control functions much like insurance that helps communities avoid far larger, unplanned expenses.

Healthcare Cost Tied to Mosquito-Borne Diseases

Mosquito-borne diseases carry real, measurable financial burdens in the United States. West Nile virus alone costs approximately $56 million a year in direct medical expenses. When long-term care, lost productivity, and premature deaths are also included, the total annual economic impact is estimated to reach $450 million annually.

Florida’s 2016 Zika outbreak further illustrates the long-term financial consequences of mosquito-transmitted disease. Children born with Zika-related birth defects such as microcephaly—a neurological condition where an infant’s brain does not fully develop—carry estimated lifetime care costs averaging $4 million per child. These expenses have heavily impacted Medicaid programs, state health budgets, and social services, creating long-term financial obligations that may far exceed the cost of mosquito prevention and surveillance.

The economic consequences of mosquito-borne disease outbreaks extend well beyond healthcare. During the 2016 Zika outbreak, concerns over mosquito-transmitted disease also impacted tourism, hospitality revenue, and local business activity. 

A peer-reviewed study found that 91% of surveyed local businesses reported decreased revenues compared to the same period the previous year.

Just the perception of disease risks can result in significant economic losses for communities that depend on seasonal travel and outdoor recreation. Following a CDC travel advisory for the Wynwood district of Miami, some restaurants and hospitality businesses reported revenue declines of up to 75%, which led to staff layoffs and reduced operating hours. Many business owners attributed these losses directly to public fear, even though transmission was limited to specific areas. 

As mosquito habitats expand across the country, numerous mosquito-transmitted diseases are increasing in previously unaffected regions. In fact, researchers believe as many as a billion people could be newly exposed to mosquito-borne diseases within the century.

How Mosquitoes Impact Property Values

Property values can increase significantly when located near natural areas. Properties close to parks and green spaces typically sell at price points 5-20% higher than similar homes farther away.

But these areas can also serve as habitats for various mosquito species. Painful, itchy bites and concerns about mosquito-transmitted diseases discourage outdoor use, reducing enjoyment of yards, patios, parks, and waterfronts. This, in turn, may lower the overall appeal and desirability of a community, especially in amenity-focused areas.

The Cost of Reaction vs Prevention

Once a disease outbreak commences, response costs escalate rapidly. Research consistently shows that proactive surveillance and early intervention are far more cost-effective than outbreak response:

  • A proactive mosquito monitoring program in Brazilian cities prevented an estimated 27,000 dengue cases, saving a combined $364,000 in direct healthcare and control costs and more than $7 million annually in avoided lost wages.

  • A study by Emory University revealed that cutting back on mosquito surveillance can increase epidemic management costs by more than 300-fold compared to sustained monitoring and early detection. 

  • Long-term economic evaluations indicate that maintaining city mosquito control programs often costs a little more than responding to outbreaks alone once medical treatment, emergency response, and productivity losses are factored in. Even programs that achieve only a 50-70% reduction of mosquitoes can remain economically valuable.

Furthermore, evidence suggests the public generally supports stronger mosquito control efforts. A New Jersey study found that residents were willing to pay about $9.50 per person per year through taxes or donations for improved mosquito management. When combined across the community, the perceived benefit totaled nearly $10 million annually. That’s almost four times the existing mosquito control program’s costs, indicating that residents valued mosquito abatement well above what was being spent.

Understanding the True Cost of Integrated Mosquito Management

Integrated Mosquito Management is not about eliminating mosquitoes entirely. It is about reducing populations to safe levels through surveillance, data-driven decision-making, habitat modification, larval control, and targeted adult mosquito control when necessary. 

Programs are tailored, and costs are based on a range of factors:

  • Scope and size of the service area
  • Program components included
  • Type of control methods required
  • Local disease risk and mosquito pressure
  • Seasonality and flexibility needs
  • Emergency response preparedness
  • Action thresholds and insecticide resistance management
  • Public education and communication
  • Contract structure and cost sharing

The Big Picture

The takeaway is clear: most communities will pay for mosquito control whether they plan for it or not. The difference is whether those costs are predictable or reactive. An IMM program helps communities avoid unplanned expenses and preserve quality of life.

Everyday Items Around Your Citizens’ Homes That Attract Mosquitoes

Where Do Mosquitoes Lay Eggs?

All mosquito species require water to breed and complete their lifecycle. Mosquitoes lay their eggs in or near stagnant water, where they hatch into fully aquatic larvae. The larvae feed and develop in the water until they pupate, leaving only after the fully mature adult emerges from the pupa and flies off. However, different mosquito species require different water sources, and each source can be categorized into one of three groups: permanent water mosquitoes, floodwater mosquitoes, and container mosquitoes.

Permanent Water:
These mosquitoes seek out large standing water sources, such as stagnant ponds and marshes, to breed. Many species will lay their eggs directly on the water’s surface, while others will lay their eggs on aquatic plants. Most mosquitoes will seek out freshwater sources; however, some mosquito species are able to breed in coastal salt marshes.

permanent-water-mosquito-on-water-surface (2)

Floodwater:
While all mosquito eggs need water to hatch, some species are capable of “waiting it out.” Floodwater mosquitoes lay their eggs on or just above the water line of plants or other aquatic structures near ditches or floodplains. The eggs are able to survive in a dormant state when these places are relatively dry, and then hatch when they flood. This can lead to large, localized spikes in mosquito numbers after heavy rainfall, when many of these mosquitoes’ eggs hatch simultaneously.

floodwater-mosquito-breeding-sites (3)

Containers:
Container-breeding mosquitoes lay their eggs in nearly anything capable of holding water. Common sources often include artificial containers such as discarded tires, buckets, and bird baths and natural containers such as tree holes or leaf axils of plants. Container mosquitoes are especially problematic in urban areas and suburban areas where many of these containers are found within the environment. Fortunately, there are plenty of precautions citizens can take to eliminate these breeding sites.

containers-mosquito-breeding-sites (2)

Common Mosquito Breeding Containers Near Homes

Container mosquitoes will use nearly anything that holds water as a breeding site. Containers do not need to be especially large or permanent to host container mosquito larvae. Here are just a few of the small but common containers these mosquitoes will seek out:

  • Buckets
  • Flowerpots and planters
  • Leaf-clogged gutters 
  • Old tires
  • Wheelbarrows
  • Bird baths
  • Trash cans
  • Swimming pools
  • Pet dishes

Because some container mosquitoes like Aedes aegypti and Aedes albopictus are potential disease vectors, it can be just as important to monitor container sources as it is permanent water and floodwater sources. Fortunately, there’s plenty the average citizen can do to help eliminate container breeding sites.

What Can Citizens Do to Reduce Mosquito Breeding Sites?

Because of mosquitoes’ quick life cycle, it’s important to limit breeding sites on an ongoing basis, and especially after substantial rainfall. Cleaning up a property and removing any discarded cups, jars, old tires, or other debris is a great start. Ensuring that gardening equipment like wheelbarrows and buckets are either covered or turned over when not in use can prevent them from becoming breeding sites later on. Clearing clogged gutters or planters is a great next step, and draining any larger water sources like unused swimming pools can also go a long way toward limiting the spread of container mosquitoes and potential mosquito-bite diseases.

The Battle Against Mosquitoes: What Does “Winning” Look Like?

Mosquitoes Are Here to Stay—So What Does Success Look Like?

Mosquitoes have existed for over 100 million years, surviving through the Jurassic Period, the Ice Age, and numerous environmental extremes thanks to their remarkable adaptability. While it’s appealing to imagine a world free from itchy mosquito bites, completely eliminating mosquitoes is an unrealistic goal. “Winning” the battle isn’t about eliminating all mosquitoes; it’s about protecting public health by reducing the mosquito population to a manageable level, thereby reducing the spread of vector-borne diseases. Historical precedent suggests this is only possible through a coordinated, integrated management approach.

Ancient Mosquito Preserved in Amber

A Historic Example of Targeted Mosquito Control

For example, in the 1950s, Anopheles gambiae, a vector of malaria, was accidentally imported from Africa to Brazil, leading to thousands of deaths. In response, Brazil launched a highly organized campaign to eliminate this invasive species. This involved daily surveys, mapping infestations, and suffocating larvae by applying oil to their preferred breeding sites—puddles, irrigated fields, and even water that collected in cattle hoof prints. Because Anopheles gambiae feeds exclusively on humans and stays close to its breeding areas, teams could systematically move from the outskirts of communities inward. This approach successfully eliminated the Anopheles gambiae from Brazil and stands as one of the most historically successful mosquito elimination programs ever instituted.

Why Short-Term Mosquito Management Programs Fall Short

Similar strategies were used in the United States in the 1960s to control Aedes aegypti, the primary vector of yellow fever. Programs combined careful monitoring, habitat management, and door-to-door community education. Residents were encouraged to eliminate standing water from buckets, tires, birdbaths, and other small containers that serve as Aedes aegypti breeding grounds. These efforts temporarily reduced their populations to near-zero numbers in some areas. Unfortunately, when the program ended in the early 1970s due to funding and commitment challenges, this mosquito species rebounded in full force.

Clsoe-up-mosquito
dumping-standing-water

These examples illustrate that mosquito population dynamics are always evolving, particularly due to increased global trade, travel,  insecticide resistance, and climate change, which are creating new areas and conditions for mosquitoes to spread. Today’s mosquito management programs build on the lessons and successes of past initiatives. They are scientifically precise, carefully tailored, and designed to achieve maximum impact while minimizing environmental effects. 

Targeting Mosquitoes at Every Life Stage

VDCI’s Integrated Mosquito Management (IMM) programs are defined by four pillars: surveillance and disease testing, larval control, adult control, and public education. By leveraging the latest technologies and targeting mosquitoes at every stage of their life cycle, these programs can help reduce mosquito populations and the risk of disease transmission. Nonetheless, true success depends on the support and cooperation of the local community, particularly in removing standing water where many urban mosquitoes breed.

The Cost of Letting Mosquito Control Lapse

Historical examples prove that when mosquito management is prioritized, populations can be effectively managed. However, they also demonstrate that if efforts lapse due to funding gaps, political changes, or public disengagement, decades of progress can be quickly reversed. Government leaders and public health officials must recognize that the battle against mosquitoes can never be truly won. It is a continuous effort that requires a sustained investment in time, resources, and community education.

How Urbanization Impacts the Mosquito Population

What Communities Can Do to Control Mosquito Breeding in Urban Areas

Urban development changes the natural landscape, and while the effects on native plants and wildlife are often discussed, these conversations rarely include mosquitoes. It’s important to understand that whenever environmental conditions shift, mosquito dynamics can also change. And when mosquito dynamics change, new public health risks may emerge.

Hundreds of mosquito species can be found around the globe, each of which are adapted to specific ecological niches. Some, such as “tree-hole” mosquitoes, are typically found in undisturbed, forested areas where they rely on wildlife for blood meals. Others thrive in well-populated urban areas. These mosquitoes breed in standing water that collects in small artificial containers like plant saucers, old tires, outdoor pet bowls, clogged gutters, buckets, and even bottle caps.

mosquito-breeding-sites-public-education-awareness

It’s Not About More Mosquitoes — Just Different Ones

It’s natural to assume that urban development causes mosquitoes to move from cities into rural areas, or vice versa. In reality, urbanization tends to reduce the presence of mosquitoes adapted to rural and sylvatic (forests) environments while creating ideal conditions for species that thrive near humans. This shift doesn’t necessarily result in more mosquitoes overall, but it does increase populations of species that are likely to bite humans, causing viruses to spread more widely and rapidly.

Here are some mosquito species and diseases city residents should be aware of:

Culex quinquefasciatus is the primary vector of the most widespread disease in the country, West Nile virus (WNv). Culex quinquefasciatus can also serve as a secondary vector for Oropouche virus (OROV). OROV has been primarily isolated in South American countries like Brazil and Peru since the 1960s, but has spread significantly in a short period. Since 2024, over 120 cases have been identified in the U.S., likely due to travel-related exposure1.

Other urban mosquitoes, including Aedes aegypti and Aedes albopictus, feed primarily on humans. They search for bloodmeals during the day when humans are most active, and are highly efficient vectors of diseases such as dengue, Zika, and chikungunya.

The 4Ds: Protect Yourself from Dangerous Mosquitoes

Whether you live in an urban or rural area, it’s important to protect yourself from biting mosquitoes by practicing the “4 D’s.”

DEFEND

●   Use an EPA-approved repellent

●   Protect pets with heartworm prevention

DRESS

●     Wear light-colored, loose-fitting clothes and closed-toe shoes.

●     Apply repellent to exposed skin on hands, ankles, neck, and face.

DRAIN

●     Eliminate mosquito breeding sites by emptying standing water in buckets, birdbaths, tarps, plant saucers, and other containers.

●     Ensure gutters, flower pots, rain barrels, and stormwater systems drain properly.

DUSK & DAWN

●     Limit outdoor activity when mosquitoes are most active - Urban mosquitoes typically feed at dawn and dusk and rest in shaded, cool areas during the day.

Planning Ahead to Protect Public Health

Personal protection goes hand in hand with an Integrated Mosquito Management (IMM) program. These programs are designed to monitor changes in mosquito populations, identify new disease threats, and initiate targeted solutions. Surveillance and disease testing, larval and adult mosquito control, and public education are core pillars of an effective IMM program. Every city and region is different, which is why IMM programs are tailored based on goals, budgets, risk levels, and many other factors.

In many areas, urban development is only accelerating, but with proper planning, communities can stay ahead of mosquito-related threats as landscapes and populations change.

Understanding the Mosquito Life Cycle

Close up a Aedes aegypti mosquito on human skin

What are the life stages of a mosquito?

Understanding the developmental processes of mosquitoes is crucial to keeping them under control. While there are thousands of different mosquito species, they all undergo complete metamorphosis. This means they have a lifecycle which includes four distinct growth stages: egg, larva, pupa, and adult.

Watch the video below to learn more about the process. 

A Deep Dive Into the Mosquito Life Cycle

Most female mosquitoes lay their eggs in or near water, just above the water line, or moist soil in areas that are prone to flooding. Most mosquitoes can be categorized as floodwater, permanent water, or container species based on the types of habitats utilized for larval development. 

Where Do Mosquitoes Lay Their Eggs?

Floodwater

Floodwater mosquitoes lay eggs in low-lying areas that temporarily fill with water, such as ditches, agricultural lands, or dry basins. These eggs will hatch when they become submersed during rainfall or flooding events.

Permanent

Permanent water species lay their eggs on standing waterbodies like ponds and marshes. 

Container

Container species lay their eggs on the edge of small stagnant water vessels, such as bird baths, buckets, and even bottle caps. 

What are the life stages of a mosquito?

The Larval Stage

Once exposed to water, larvae will typically hatch from their eggs within 48 hours. During this stage, most larvae suspend themselves near the surface, breathing through a siphon-like tube, and feeding on organic matter and microorganisms. 

mosquito life cycle

The Pupal Stage

Over the course of approximately 4 to 14 days, larvae will shed their skin, or molt, 4 times before developing as pupae

Pupae continue to develop near the surface, resembling small, squirming commas. 

The Adult Stage

After two to four days, adult mosquitoes emerge from their pupal exoskeletons and exit the water as adults. Blood meals are essential for some mosquito species, and it is important to note that only the females seek blood-meals, which provide the nutrition necessary to support egg development.

Though male mosquitoes typically die within five to seven days, females can live several months and are capable of laying thousands of eggs. During this time, many species are capable of vectoring dangerous diseases like West Nile Virus, Yellow Fever, Zika, Dengue, and Eastern Equine Encephalitis.

Our understanding of the diversity of mosquito species and their unique life cycles is instrumental in developing effective management strategies to maintain safer, more enjoyable outdoor spaces.

Using Your Smartphone to Help Monitor Mosquito Activity

guy-sitting-with-dog-outside-on-phone

As warm weather begins to take hold across North America, many people are itching to get outside and enjoy more seasonal temperatures. However, in the wake of a very wet winter and spring in many parts of the United States, scientists are already raising the red flag about heightened mosquito activity in 2023. 

As the climate continues to change, new mosquito species are becoming more prevalent in the United States, particularly in more tropical areas of the country, like Florida and the Gulf Coast states. For example, in March 2023, new research by Larry Reeves from the University of Florida’s Institute of Food and Agricultural Science published in the Journal of Medical Entomology reported on Culex lactator, a mosquito species from South America that is slowly gaining a foothold in Florida. Understanding how fast new species like this are spreading, where they are being found, and how they adapt to new climates is critical to developing control methods. 

With the rapid evolution of technology, mosquito researchers are now looking toward ordinary citizens to help gain some of this knowledge, elevating “citizen science” to a new level in helping to understand mosquito activity around the globe. Two new apps, available to anyone using a smartphone or web-enabled tablet, are now making it easier for scientists to track and understand mosquito activity with the help of citizens interested in protecting public health from mosquitoes. 

What is citizen science?

The term “citizen science” was first coined in 1989 by researchers at the Massachusetts Institute of Technology (MIT) in describing work being done by community members who were interested in environmental issues. 

The Cambridge Dictionary defines citizen science as “scientific work, for example collecting information, that is done by ordinary people without special qualifications, in order to help the work of scientists.” 

By this definition, any of us can help enable mosquito research from our communities and even our backyards if we know what to look for and how to report it. That’s where two easily downloadable applications, the Globe Observer app and the Mosquito Alert app, empower everyday citizens to help inform scientists about mosquito activity with just a few taps on their smart devices. 

Mosquito Research Safety Precautions

Before using either of the apps in this article, it is important to note that voluntarily engaging in any mosquito research activity can increase your likelihood of being bitten by mosquitoes, which can spread diseases that are harmful to humans and our pets, such as West Nile virus, heartworm, Eastern equine encephalitis (EEE), dengue, and more. 

As such, it is important to take safety precautions if you plan to be outside or in any area where mosquitoes are known to be active. Remember the 4Ds to help reduce your chances of being bitten. 

  • DEFEND – Always protect yourself by using a U.S. Environmental Protection Agency (EPA)-registered insect repellent. 
  • DRESS – Dress in closed-toe shoes and loose-fitting pants and long-sleeve shirts that are light in color. Avoid wearing perfumes or other scented products that may attract mosquitoes. 
  • DRAIN – Remove or drain any standing water. 
  • DAWN AND DUSK – Avoid the outdoors during dawn and dusk hours when mosquitoes are most active.

The Globe Observer App

Powered by the United States National Aeronautic and Space Administration (NASA), the Globe Observer app enables users to enter data and information in 4 different areas: clouds, land cover, trees, and the mosquito habitat mapper. For this blog, we’ll focus on the latter area. 

Mosquito_habitiat_mapper_screenshot
Observer_app_Screenshot

To best use the Globe Observer app, users will need to do the following:

  • Download the app to your smart device.
  • Create an account using their email address and verify through a password emailed to the supplied email address.
  • Enable location services while using the app; this allows for the app to easily help you report mosquito breeding habitats.
  • Take photos using your smart device.
  • Allow access to your device’s camera for uploading photos of habitats and larvae.

For safety purposes, this app focuses users on recording data related to mosquito breeding sites and larvae rather than tracking adult mosquitoes.

Once users have downloaded the app and created their account, they can use the mosquito habitat mapper to take one of four actions:

  1. Identify potential mosquito habitats
  2. Sample and count mosquito larvae (using a cup, bulb syringe, or other container)
  3. Identify the larva type (may require a microscope or macro lens on your device’s camera)
  4. Eliminate the larva you have counted and the breeding habitat, if possible

Each of these actions can be taken with a few simple taps, by following the directions provided on each screen.

Users can also view maps of the mosquito observations that other users have made by clicking on the chart icon at the bottom left corner of the screen from anywhere in the app and selecting the See Today’s Mosquito Measurements button. The feature works best when you view it over a cumulative time period. Users can leverage the calendar and zoom features to see further details of activity recorded by other citizen scientists. 

Screenshot_map_mosquitoes

The Mosquito Alert App

A public information project coordinated by four different research organizations, the Mosquito Alert app works similarly to the Globe Observer app to help citizens report a variety of different mosquito-related conditions to help monitor activity in their area. Data for this citizen science project has been recorded since 2014. 

The Mosquito Alert app is based internationally in Spain, developed by the Centre for Ecological Research and Forestry Applications (CREAF), Pompeu Fabra University (UPF), Catalan Institution for Research and Advanced Studies (ICREA), and Blanes Center for Advanced Studies (CEAB-CSIC). As such, many of the current users of the app are based in Europe, but the activity maps do reflect some reports in the Americas. 

To best use the Mosquito Alert app, users will need to:

  • Download the app to your smart device.
  • Create an account.
  • Enable location services while using the app for mapping purposes.
  • Take photos using your smart device.
  • Allow access to your device’s camera for uploading photos of mosquitoes, bites, and more. 

The Mosquito Alert app is focused specifically on five different mosquito species that are particularly important in the spread of disease to humans. 

By clicking on the Settings icon at the top left from any screen of the app, users can access an app tutorial on mosquito identification or a Mosquito guide to note distinguishing features that can help identify particular mosquito species, see photo examples of mosquito larvae and breeding sites, and more.

Once users have set up an account, they can use the app to take one of four actions:

  • Report a mosquito bite
  • Report adult mosquito activity
  • Report a breeding site
  • Or view data they have submitted
mosquito alert app on phone
app that monitors mosquito activity

When reporting a bite, users will be asked several questions:

  • How many bites they received
  • Using a diagram, select where on their body they were bitten 
  • Select your general location where you were bitten (inside a vehicle, inside a building, outdoors, or do not know)
  • When they were bitten

If users use the app to report a breeding site, a different set of questions will appear. They will be asked whether or not the site is a storm drain or another location. For either option, users will be asked to take a photo of the location. 

If reporting an adult mosquito, the user will be asked to select the type of mosquito they think it was by species, take a photograph if possible, and mark their location (if location services are enabled on the user’s device, the device will automatically record the location on a map).

As of April 2023, the Mosquito Alert app reports having over 278,000 participants around the world and averages nearly 30 reports from citizen scientists each day.

Screenshot_20230224_122204

It's Up to Us to Improve The Data

As with any scientific project, data is invaluable. These apps, and the data they provide to mosquito researchers, will get better as more users report mosquito breeding sites and activity near their locations. YOU can be a part of this important citizen science by downloading one or both of these apps and reporting mosquito conditions near you. 

If you work with or have children, utilizing these apps can be a great science project and learning opportunity by involving them in STEM (Science, Technology, Engineering, and Mathematics) while they are young. 

Don't Forget To Report Mosquitoes To Your Local Authorities

While citizen science apps are a helpful tool for global research, it’s important to remember to report mosquito breeding sites and unusual mosquito activity to local authorities in your community. This will ensure the quickest and most effective action is taken to reduce the risks mosquitoes pose to you, your family, your neighbors, and your community at large. 

While the authority you should report activity to varies by community, calling your local mosquito control board or health department is typically a great start. In some communities, you may be able to call 311 and ask about reporting mosquitoes to get you to the right resources.
