Fighting Insecticide-Resistant Mosquitoes: How You Can Help

How to Help Avoid Insecticide-Resistant Mosquitoes

In the ongoing battle against mosquito-borne diseases, an ongoing challenge has emerged that threatens to undermine public health efforts and the effectiveness of existing control strategies: insecticide resistance. As these insecticide-resistant mosquito populations grow, the tools and methods we rely on for mosquito management can become less effective, potentially leading to increased mosquito-borne disease transmission or nuisance populations. Understanding insecticide resistance, its causes, and its implications is crucial for executing successful mosquito management programs.

This is where Vector Disease Control International (VDCI) steps in. As a leader in mosquito management, VDCI is at the forefront of developing and implementing control strategies to help prevent insecticide-resistant mosquitoes. By leveraging surveillance and data to drive mosquito management efforts, conducting rigorous insecticide resistance testing on mosquito larvae and adults, and fostering community education and participation, VDCI aims to protect public health while preserving the efficacy of insecticides for future generations. 

What Causes Mosquitoes to Become Insecticide Resistant?

There are many reasons why insecticide-resistant mosquitoes can develop. It often occurs when a single class of products is relied on to manage an outbreak or a product is overused within a particular area. Over time, this can lead to mosquito populations developing genetic mutations where insecticides intended to manage them become less effective. When a mosquito develops this genetic mutation, it can pass on this trait to its offspring. Over time, this mosquito population develops resistance and is no longer affected by the insecticide class used. This phenomenon makes insecticide resistance monitoring critical in all mosquito management programs.

In the United States alone, the agricultural sector applies over a billion pounds of pesticides annually, which includes insecticides that share similar active ingredients with those used in mosquito control programs. The Insecticide Resistance Action Committee (IRAC) has noted that insecticide-resistant mosquitoes can emerge when mosquitoes are exposed to these similar compounds through agricultural applications. The use of pesticides in agriculture, combined with insecticides used in mosquito management, underscores the importance of insecticide resistance monitoring.

Types of Insecticide Resistance

Even with the implementation of best practices, such as responsible product usage and continuous monitoring, it’s likely that some degree of insecticide-resistant mosquitoes will emerge due to natural variations within wild populations. Identifying the specific type of resistance that has developed is a crucial step in devising an effective management strategy to counteract it.

    • Cross Resistance: When a mosquito becomes resistant usually to a similar class of insecticides due to the presence of one or more common resistance mechanisms.

    • Multiple Resistance: When a mosquito becomes resistant to two or more insecticides due to multiple mechanisms of resistance.

    • Target-Site Resistance: When a mosquito develops a point mutation within the insecticide target region, preventing the insecticide from acting effectively. These point mutations occur in the nervous system and involve the sodium channels, acetylcholinesterase and or GABA receptors.

    • Behavioral Resistance/Avoidance: When mosquitoes alter their behavior to avoid exposure to specific products, such as not landing on surfaces that have been treated with insecticides.

Impact on Integrated Mosquito Management

The most effective strategy for controlling mosquitoes and reducing the spread of mosquito-borne diseases is an Integrated Mosquito Management (IMM) program. However, insecticide-resistant mosquitoes pose a significant challenge to IMM efforts and public health. Once mosquitoes develop resistance, mosquito control measures, a cornerstone of IMM strategies, can lose their effectiveness. When applications are less effective, mosquito populations can rise, which in turn, raises the risk of disease transmission to humans. Diseases such as dengue fever, EEE, and West Nile virus, could see surges in case numbers as control measures fail to effectively suppress mosquito populations.

To effectively control adult and larval mosquito populations, ongoing monitoring and data collection should take place throughout a management program.

Testing for Insecticide-Resistant Mosquitoes

Various methods are available to evaluate how susceptible local mosquito populations are to control measures. Among these, the CDC Bottle Bioassays is the primary method for detecting insecticide-resistant mosquitoes. During this testing process, adult mosquitoes are placed in bottles coated with a diluted insecticide solution. These mosquitoes are then compared to a control group, enabling experts to gauge the pesticide’s effectiveness over time.

Other insecticide resistance tests include the WHO Tube test, which assesses adult mosquitoes, and the cup bioassay testing, which tests larvae against larvicides.

VDCI’s Fight Against Insecticide Resistance

VDCI is at the forefront of combating the growing challenge of insecticide-resistant mosquitoes. We recognize the critical importance of staying ahead of resistance patterns and prioritize regular testing of mosquito populations to help detect the early signs of insecticide resistance. This testing is not a mere formality but a crucial tool in our arsenal, enabling us to detect shifts in the effectiveness of various insecticides. The insights gained from these tests guide our mosquito control strategies and allow us to review the insecticides we deploy, how we apply them, and the timing and specific locations of treatments. 

How Can The Public Help Prevent Insecticide-Resistant Mosquitoes?

In the fight against insecticide-resistant mosquitoes, there are several practical steps everyone can take to reduce insecticide resistance and protect themselves from mosquito-borne diseases. One effective approach is the elimination of mosquito breeding habitats. Mosquitoes lay their eggs in standing water, so by diligently dumping out any stagnant water around homes—such as in plant saucers, bird baths, and blocked gutters—citizens can significantly reduce breeding grounds. 

Beyond these actions, educating oneself about mosquito-borne diseases and their prevention is crucial. Understanding the life cycle of mosquitoes, breeding habits, and the diseases they can carry equips individuals with the knowledge to implement more effective protective measures. This includes adopting practices such as wearing long-sleeved, light-colored clothing, avoiding the outdoors during peak mosquito activity, and applying EPA-approved mosquito repellents. By combining practical actions with science-backed strategies, citizens can help reduce the impact of insecticide-resistant mosquitoes and protect public health.

Common places mosquitoes lay their eggs

Do you know where mosquitos breed?

Mosquitoes are well-known for their ability to breed in various environments. Recognizing where these insects choose to lay their eggs is crucial to effectively manage nuisance mosquitoes, as well as reduce the spread of harmful diseases that some can carry. Through continuous surveillance, we can better understand mosquito species and population dynamics, detect insecticide resistance, and intervene by draining or treating water before mosquito larvae complete their life cycle. This information also guides strategies for managing adult mosquitoes, empowering communities to optimize resources by applying insecticides in the right areas, at the right times, and in the right amounts. 

Container Mosquitoes:

Container mosquitoes like Aedes aegypti and Aedes albopictus deposit their eggs directly along the water line of the inside surface of containers. Containers can vary from natural containers such as tree-holes and the axis leaves of plants, to a wide range of artificial containers including tarps, discarded tires, clogged gutters, buckets, flower pots, bird baths, and playground equipment.

mosquito-breeding-site-tire

Floodwater Mosquitoes:

In contrast, floodwater mosquitoes, most commonly the Aedes and Psorophora genera, lay their eggs on plants and along the water-soil line, often in areas prone to flooding during storms. When precipitation arrives, the eggs are submerged in water, triggering their hatching and initiating the mosquito life cycle. These species may also utilize temporary pools of water created by rainfall for larvae development.

digging-inground-breeding-habitat

Permanent Water Mosquitoes:

Permanent water mosquitoes from the Anopheles and Culex genera often lay their eggs on ponds, swamps, marshes, water treatment facilities, and other waterbodies that remain stagnant for long periods of time. These permanent aquatic habitats tend to be expansive and can sustain substantial mosquito populations over time, leading to persistent problems. 

back-yard-flooded

Understanding the Mosquito Life Cycle

In addition to knowing where mosquitoes lay their eggs, understanding the mosquito life cycle is also integral for effective management. Mosquitoes undergo a complete metamorphosis over four distinct stages: egg, larva, pupa, and adult. After larvae hatch from their egg, they feed on organic matter present in the water and molt several times before transforming into a pupae. The pupal stage is a non-feeding stage during which the mosquito undergoes metamorphosis into its adult form. Finally, the adult mosquito emerges from the pupal case and the females seek a blood meal to fuel egg production, thus continuing the cycle.

Control Mosquitoes with Source Reduction

Effective mosquito control strategies are supported by eliminating or treating potential breeding sites. Discarding standing water from containers, ensuring proper drainage of ditches and gutters, and regularly maintaining swimming pools and other water features are essential steps in reducing mosquito breeding habitats. Additionally, larviciding treatments targeting mosquito larvae in stagnant water sources can help prevent their development into nuisance and potentially disease-carrying adults. Public education can help ensure these practices are implemented across a community. Educational efforts should also include tips for personal protection, such as wearing light-colored long sleeves and pants, using mosquito repellent containing DEET or Picaridin, and avoiding the outdoors around dawn and dusk when mosquitoes are most active. 

mosquito-breeding-site-pan

Mosquitoes have adapted to lay their eggs in various habitats, so understanding these diverse breeding sites and the mosquito life cycle is essential for effective population control. By taking proactive measures to eliminate stagnant water and maintain proper drainage, individuals can play a crucial role in reducing mosquito populations and mitigating the risk of mosquito-borne diseases. Just a small step in eliminating breeding sites can make a significant difference in supporting an integrated mosquito management program that emphasises protecting public health and well-being.

A Day In the Life of a Mosquito Control Lab Technician

Exploring the Importance of Mosquito Lab Analysis

When the public observes a Vector Disease Control International (VDCI) truck conducting spraying, it may appear routine, or even go unnoticed. However, what many folks don’t realize is the meticulous planning and scientific precision that is calculated for each spray route. Behind the scenes, a dedicated team of experts ensures every decision, from location selection to insecticide dosage and spray time, is backed by rigorous research and analysis.

insecticide-resistance-testing

“Most people are only familiar with the trucks and may not realize there’s a lot more to mosquito control,” Jennifer Riley, VDCI’s Louisiana-based biologist and lab technician said. “I think people would be surprised to learn that there is someone in the lab every day to help ensure the efficacy of our operations.”

Evaluating Mosquito Larvae for Insecticide Resistance

Jennifer specializes in monitoring for larval and adult insecticide resistance, the process by which mosquitoes become less susceptible to insecticides used to control them, either through genetic mutations or behavioral changes. Overuse or unnecessary spraying of insecticides can contribute to the development of resistance. 

To evaluate mosquito larval resistance, Jennifer visits different locations in her jurisdiction to conduct field tests directly on-site. Using tools like mosquito dippers, she quantifies the larval presence in ditches, containers, or other sites where water has pooled. She then calculates and administers a precise larvicide dosage to the water, returning approximately 24 hours later to evaluate the efficacy of the product and identify any signs of resistance. 

“Sometimes it’s hard to find breeding locations and I can be out all day looking for sampling sites,” Jennifer said. “I joke that I’m the only one who gets excited when mosquitoes start breeding again after winter. It’s such a thrill to find one of those really busy ditches.”  

Testing Adult Mosquitoes for Insecticide Resistance

Jennifer also collects mosquito larvae and rears them to adults in the lab for testing adulticide resistance. The mosquitoes are kept in a warm, humid enclosure called an insectarium to maintain their health and vitality until they’re ready for testing. Artificial lights are regulated to mirror day and night cycles, and they’re provided with sugar water to mimic the nectar they feed on when not seeking blood meals.

mosquito_breeding

“It’s crucial to replicate the environmental conditions they’re familiar with to prevent results from being skewed,” Jennifer explained. 

Adulticide tests are conducted in the lab with the CDC bottle bioassay. To protect their delicate wings, mosquitoes are gently aspirated from the insectarium and transferred into bottles containing a diluted adulticide solution for observation. Mortality rates are then compared to a control group to detect any signs of insecticide resistance. 

insecticide resistance - bottle assay

Adulticide tests are also conducted in the field to replicate real-world conditions in which a nighttime spray mission would occur. This helps to account for variables like air pressure, humidity, wind, and temperature. Adult mosquitoes are placed in containers at various intervals within a range of a few hundred feet. A passing truck sprays adulticide and a post-spray mosquito examination determines mortality rates. These tests ensure that the truck’s speed and spray droplet size are appropriate to target mosquitoes while minimizing the impact on non-target insects and wildlife.

What Happens When Insecticide Resistance Is Detected?

If insecticide resistance is detected in any of these assessments, the next step is to determine how far the resistant population has spread beyond the initial testing site. This may involve placing adult mosquito traps at strategic intervals for additional testing or collecting larval samples from other sites in the surrounding area. 

“After I’ve identified a potential problem, we want to see how big the problem really is,” Jennifer said. “Then, we may discuss rotating insecticide products or altering the formula to ensure our efforts remain safe and effective.” 

In addition to rigorously monitoring and testing for insecticide resistance, Jennifer provides support to other experts involved with mosquito species identification, population counting, and disease testing. This collaborative, science-backed approach helps ensure insecticides are only sprayed in the right locations, in the right dosages, at the right times. 

Colleague-counting-mosquitos

Her job is not without its challenges. Environmental factors complicate the task of locating mosquito larvae in the field. In droughts, mosquito populations may surge despite the scarcity of water, making it more difficult to locate breeding sites. Conversely, heavy rainfall can completely wash away larvae habitats, preventing accurate sampling. 

Encounters with unwanted creatures—inside and outside of the lab—are also a possibility. 

“Once, I was sampling larvae in a septic ditch. Just as I went to reach in, I was fortunate to notice there was an alligator,” Jennifer said. “Spiders have also hatched in the insectarium and I have to figure out how to keep them from eating all of my insects.”   

Despite these challenges, Jennifer likes that her job is never boring. 

“Every day is a little different. I love lab work, but I also like being out looking for larvae and seeing the beauty of the state. It’s a great balance for me.”

What’s Your Community’s Action Threshold? Knowing When to Spray for Mosquitoes

Know When to Spray for Mosquitoes with Action Thresholds

There is no one-size-fits-all approach to responsibly and effectively managing mosquitoes. Every jurisdiction faces unique challenges that may be influenced by community desires, budgetary constraints, prevalent mosquito species, disease risks, and local environmental factors. To optimally address these challenges and safeguard public health while minimizing the risk of insecticide resistance, professionals rely on action thresholds.

Action thresholds serve as critical benchmarks in an Integrated Mosquito Management (IMM) program. They represent the tipping point at which control measures become necessary to reduce the potential of mosquito-borne diseases, nuisance mosquito populations, or prevent a particular species from reaching levels that pose a significant risk to public health. Action thresholds are not arbitrary; they are meticulously tailored to the specific goals and characteristics of each jurisdiction.

What does it take to develop action thresholds?

Developing action thresholds involves a multidisciplinary approach that integrates scientific expertise with local knowledge and community input. Entomologists, government leaders, and public health officials collaborate to assess various factors, such as mosquito abundance, disease prevalence, ecological dynamics, and human population density. Through comprehensive mosquito surveillance, disease monitoring, and data analysis, mosquito experts identify thresholds that signal the need for targeted control interventions.

Aerial Spraying Malcom 8

One of the primary objectives of employing action thresholds is to ensure the judicious and effective deployment of mosquito control products. Over-reliance on insecticides without regard for action thresholds can accelerate the development of insecticide resistance among mosquito populations, causing control measures to lose their effectiveness over time. Applying insecticides only when mosquito populations exceed predetermined thresholds or if a particular species or disease is present can reduce insecticide resistance and prolong the efficacy of available insecticides – with the ultimate goal of limiting the environmental impact. 

Action thresholds also enable authorities to prioritize locations most in need of intervention. By strategically focusing resources on areas where mosquito populations pose the greatest risk to public health, interventions can be more impactful. This facilitates funds, time, and manpower to be utilized more effectively. Moreover, this limits unnecessary insecticide applications, ensuring our actions are environmentally responsible and prudent. 

The Importance of Community Engagement In Mosquito Management

vdci-education-public

Furthermore, action thresholds serve as a valuable tool for community engagement and communication. By transparently communicating the rationale behind mosquito control decisions and their thresholds, authorities can foster trust and cooperation within the community. Empowering residents with this knowledge also encourages participation in preventive measures and promotes a shared responsibility for mosquito control.

Action thresholds play a vital role in effective mosquito management by providing clear guidelines for intervention based on scientific evidence and community-specific factors. By employing targeted interventions only when and where they are needed, authorities can optimize the allocation of resources, limit environmental impacts, and safeguard the health, happiness, and well-being of the public.

Professional Mosquito Trapping: Basics, Benefits & More

How Professional Mosquito Trapping Works

Mosquitoes are more than just pesky insects that cause itchy bites in the summer months – they can also transmit harmful diseases, making them a threat to public health. Professional mosquito trapping is utilized by experts to gain a better understanding of the local adult mosquito population and determine if a potential disease threat exists. Professional mosquito traps serve as important tools to determine the mosquito life stage, species, and population size in a particular area. Once adult and immature mosquitoes are collected, they are sorted, counted, analyzed, and tested for disease so we can gather vital data that can help form more effective Integrated Mosquito Management (IMM) programs to better protect our communities from mosquito-borne diseases.

What is Mosquito Trapping?

Our entomologists employ mosquito surveillance to better understand the local mosquito populations in a given area. Adult mosquito surveillance typically includes weekly trapping of adult mosquitoes in a given area. The goal of mosquito trapping is to create a baseline of the current mosquito population, identify any population shift, understand the mosquito species distribution in an area, and monitor the threat of mosquito-borne diseases. There are various professional mosquito traps available, and each one is designed to target specific mosquito species. Determining which one to use depends on the information desired. Once the mosquitoes are captured, they are brought back to the lab for counting, species identification, and disease testing. Ongoing professional mosquito trapping helps us know when and where we need to spray to keep populations under control and when there is a risk of mosquito-borne diseases. 

Selecting The Right Type of Mosquito Traps

Selecting the right type of mosquito trap is an important aspect of mosquito surveillance. There are various types of mosquito traps. Some are designed to capture specific mosquito species or individuals during a certain life stage (host-seeking versus gravid), while others can capture a wide range of species. By using the appropriate professional mosquito trap, our entomologists can collect accurate data on local mosquito populations and determine if there is a risk of mosquito-borne diseases.

VDCI-hanging-trap

CDC Trap

CDC traps are widely used in adult mosquito surveillance. These mosquito traps are portable and run on a 6V battery with a motorized fan to collect mosquitoes. The most common model comes with a small adjustable light and may be supplemented with dry ice, which releases carbon dioxide (CO2), thereby acting as a mosquito bait source to mimic the exhaled respiratory gases of birds or mammals. Once drawn in, the mosquitoes are forced downward by the fan into the collection net, where they cannot escape. CDC traps are typically deployed at dusk and collected after dawn to gather data when most mosquito species are active.

BG-Sentinel Trap

The BG-Sentinel trap is a specially designed mosquito trap that targets two particular mosquito species: Aedes albopictus and Aedes aegypti, which are known for transmitting viruses like dengue, chikungunya, Zika, and yellow fever. These mosquito species are common in urban environments and breed in natural and artificial containers. The BG-Sentinel trap is made up of a tarp-like material and is about the size of a five-gallon bucket. It uses an attractant such as Octenol lure, human scent lure, or CO2 to lure mosquitoes towards the trap. Once the mosquitoes are in the vicinity, a funnel located at the top of the professional mosquito trap directs them toward an electric fan (outlet or battery-powered) that pulls them into a collection net. 

Gravid Trap

Gravid traps are specifically designed to capture gravid (egg-laying) Culex mosquitoes, including Culex tarsalis and Culex pipiens, which are capable of transmitting diseases like West Nile virus, St. Louis Encephalitis, and both Western and Eastern Equine Encephalitis. Many Culex species are attracted to water containing high organic material to lay their eggs. Gravid traps utilize a black bucket containing an organic infusion, like grass or hay, that has been left to ferment for several days to mimic stagnant water. Once inside the bucket, a battery-powered fan pulls the mosquito into a collection net. To prevent the trap from becoming a breeding site, it’s important to drain the water attractant from the trap on days when no mosquito trapping is taking place, especially if the trap is located near residential areas. 

VDCI-hanging-trap

New Jersey Light Trap

The New Jersey light trap is a versatile mosquito trap that can capture large quantities of mosquitoes and a wide range of species, making it an excellent tool for mosquito surveillance programs. The variety of mosquito species caught can help determine the relative mosquito populations in an area, identify local mosquito vectors, and assist technicians in finding breeding sources. It is best used as a permanent trap and should be securely mounted about five to six feet above the ground and powered by an outlet. The New Jersey Light Trap utilizes a bright light and pulls mosquitoes into the trap via a fan. Dry ice can also be used as an attractant by suspending it above the mosquito trap in a vented container. The attractants in this professional mosquito trap tend to attract

Traps that Aren't Effective for Mosquito Surveillance

It’s important to note that professional mosquito trapping is part of a mosquito surveillance program designed to gather data on the local mosquito population. Professional mosquito traps are not the same as bug zappers or sticky mosquito traps that homeowners may use to control mosquitoes on their property. Bug zappers and sticky traps are not effective for mosquito surveillance. These traps attract a variety of other insects, which can make it difficult for professionals to form an accurate population count. Moreover, few mosquitoes are attracted to these traps, and those that are often have significant damage to their bodies, making them ineffective for mosquito surveillance purposes.

Mosquito Trapping Step-By-Step

Trapping plays a crucial role in our mosquito surveillance programs, helping us better understand the activity of the local mosquito population and develop action thresholds to determine the right time to deploy control strategies. Here’s a step-by-step breakdown of how VDCI conducts mosquito trapping:

  1. Our team determines the best locations to set mosquito traps to cast a wide net for mosquito surveillance.

  2. Based on the environment or targeted mosquitoes, we employ the type of mosquito trap needed for surveillance. Mosquito trapping is often conducted weekly over several months to ensure we get an accurate representation of the mosquito population and to understand the mosquito seasonality changes for the particular region.

  3. Once the mosquitoes are captured, they are taken back to the lab for counting and species identification or to undergo insecticide resistance testing or disease testing. 

  4. Based on the results from these tests, our entomologists will recommend control strategies to decision-makers to ensure mosquito populations do not reach dangerous or nuisance levels. 

By employing mosquito trapping as part of an IMM plan, we can provide community leaders and government entities the information they need to protect their citizens from mosquito-borne diseases and help them enjoy the outdoors.

Why Professional Mosquito Trapping Matters

Mosquito trapping is an essential part of any successful IMM program. Comprehensive mosquito surveillance helps monitor population levels, identify mosquito species in an area, and identify potential disease risks. 

Professional mosquito trapping data can also be used to determine if the population levels exceed the average number in the area or if there is a mosquito-borne disease present, and control strategies need to be deployed. This ensures our control strategies are as effective and environmentally responsible as possible. The role trapping plays in mosquito surveillance programs is crucial to our IMM programs – helping us to protect public health and keep our communities safe.

How larval surveillance and lab analysis help support mosquito management programs

Mosquitoes are not only a nuisance, but they can transmit dangerous diseases that have a significant impact on human health. That’s why monitoring and controlling their populations is crucial. One of the most effective ways to do this is through an Integrated Mosquito Management (IMM) program. 

There are four pillars of an IMM program, one being surveillance of both larvae and adult mosquitoes. Through larval surveillance, experts can identify and eliminate potential problem areas before the larvae have a chance to become adults. This process also involves collecting mosquito larvae from various breeding sites and testing larvae for insecticide resistance. With the data collected, experts can implement more effective control measures. Keep reading as we explore the importance of mosquito surveillance and how it can help protect public health.

How Larval Surveillance and Lab Testing Works

Larval surveillance is the process of monitoring the growth and development of immature insects, particularly mosquitoes, to gain a better understanding of the local population dynamics and if they are resistant to commonly used larvicides. Let’s break down how the larval surveillance process works:

  1. Mosquitoes require standing water to breed. With this in mind, experts search for common larvae sites throughout a community, like ditches, tires, marshes, bird baths, and more. Our entomologists identify mosquito larvae in water and collect them via a dip cup or a tubular suction devices for examination. 

  2. We then bring larvae back to the lab, where they undergo efficacy testing. Our entomologists conduct insecticide resistance testing to ensure the larvae aren’t resistant to common larvicides.

  3. Some larvae are set aside in our “mosquito room,” a dedicated space used to house larvae and adults for further testing, and are kept warm to mimic the ideal habitat for mosquitoes. 

  4. After placing the larvae in the room, our entomologists wait for them to develop into adults for additional insecticide resistance testing. If resistance is identified, experts can modify their control strategies to help ensure the most effective intervention strategies are used. 
mosquito-larvae-dip-cup

Why Larval Surveillance

Larval surveillance is vital to every IMM program. This critical strategy helps not only combat insecticide resistance, but it helps us identify problem areas with abundant breeding sites and implement solutions like source reduction or habitat modification. By identifying mosquito habitats and conducting efficacy testing, our experts can leverage this data and their expertise to build more effective IMM programs. 

Mosquito surveillance allows us to gain a better understanding of larval habitats and the breeding behaviors of adult mosquitoes. Through our field analysis and testing, we can take a proactive approach to mosquito management by reducing the amount of larvae that make it to adulthood and reduce the number of vectors capable of spreading pathogesn. In addition, by testing mosquitoes for insecticide resistance as larvae and adults, we can ensure we are conducting applications using effective EPA-registered larvicides that provide lasting control solutions.

Protecting Your Citizens Together

At VDCI, we know that mosquito surveillance is one of the most important aspects of an effective Integrated Mosquito Management (IMM) plan.

4 Ways Government Leaders Can Help Protect Their Citizens from Mosquitoes

Utilizing An Integrated Management Approach for Effective Control

As stewards of public health and wellbeing, government leaders shoulder the responsibility of protecting citizens from health threats posed by mosquitoes as well as ensuring they can enjoy time spent outdoors. These tiny pests can become a major nuisance and certain species transmit dangerous pathogens that can cause diseases such as West Nile, yellow fever, Zika, Eastern equine encephalitis, and dengue. With public health and quality of life on the line, government leaders can make significant strides in safeguarding their communities by engaging with a mosquito management partner that specializes in Integrated Mosquito Management (IMM).

Vector Disease Control International (VDCI) is committed to protecting public health through strategic partnerships and effective IMM programs. Integrated mosquito management is a foundational, environmentally responsible approach to mosquito management that encompasses four essential pillars: surveillance and disease testing, larval control, adult mosquito control, and public education.

#1 Mosquito surveillance and disease testing

Mosquito species have different host preferences, feeding times, habitats, and pathogen-carrying capacities. Identifying and understanding their unique biological behavior is key to effectively managing them. Mosquito surveillance involves vigilant monitoring of adult and larval mosquito populations, with all data recorded in VDCI’s proprietary database. This hinges on meticulous data collection and laboratory testing. Surveillance strategies can vary depending on the mosquito life cycle stage. Mosquito control specialists analyze parameters such as species distribution, population density, disease prevalence, and insecticide resistance in the specified area, enabling well-informed decisions for strategic intervention.

#2 Larval mosquito control

VDCI-mosquito-larvae-dip-cup-surveillance

By proactively identifying areas conducive to mosquito breeding, such as ditches, ponds, and stormwater drains via surveillance, experts can tailor and implement specific larval mosquito control solutions. These solutions may involve source reduction, habitat modification, and the introduction of natural predators such as mosquitofish. In certain cases, EPA-registered larvicides may be applied from the ground or air to help ensure sustainable larval control.

#3 Adult mosquito control

While mosquito surveillance and larviciding are initial steps in any mosquito control program, managing adult mosquito populations is a vital aspect of integrated management.

Weekly mosquito trapping is crucial to monitor adult populations. This proactive approach involves setting specialized traps to regularly observe population levels, species dynamics, and disease presence, thereby providing professionals the necessary information to promptly intervene before adult populations escalate beyond control.

When nuisance mosquito populations reach unacceptable levels or the risk of mosquito-borne illnesses is high, adulticides may be employed. Utilizing data obtained through trapping and other assessments, experts can conduct precise applications of insecticides to specific locations for safe and effective mosquito control.

#4 Public education

Public education plays a pivotal role in the success and continual progress of mosquito control efforts. To effectively protect the public from mosquito-borne diseases, citizens are urged to follow The 4Ds: Drain, Dress, Defend, and Dusk and Dawn. Encouraging individuals to drain standing water, wear protective clothing, use insect repellent, and avoid outdoor activities during peak mosquito activity times can significantly help mitigate the risk of mosquito bites and disease transmission. VDCI regularly coordinates with government agencies, media, public health departments, and other organizations to disseminate timely educational resources.

Protect Public Health with an Integrated Approach to Mosquito Management

For government leaders, a successful mosquito control program reflects proactive leadership, portraying them as vigilant guardians of public health rather than merely addressing a nuisance. Partnering with an adept mosquito control company specializing in integrated management allows leaders to reclaim valuable time that would otherwise be consumed addressing complaints and health issues linked to mosquito-borne illnesses. This collaboration not only fosters a healthier, safer community but also elevates the overall quality of life for citizens.

Adult Mosquito Control Best-Practices

Adult Mosquito Control

ULV Mosquito Spraying Explained

Mosquito populations can get out of hand very quickly. Even in small numbers, mosquitoes can endanger communities by spreading infectious diseases like West Nile virus, Zika, and Yellow Fever. Through professional Integrated Mosquito Management (IMM) programs, experts are able to monitor population levels and take action when thresholds are surpassed. Often, this means applying EPA-registered adulticides through ULV spraying to keep mosquitoes in check using industrial mosquito spray techniques. These products are an essential part of an environmentally-friendly Integrated Mosquito Management (IMM) program and offer an effective and low-risk solution to helping manage nuisance mosquito populations. Industrial mosquito spray methods are a key component of environmentally-friendly Integrated Mosquito Management (IMM) programs.

What is ULV Spraying?​

ULV stands for ultra-low volume sprays, a common industrial mosquito spray technique. When applied with ULV equipment via truck, backpack foggers, or plane, adulticides remain suspended in the air as fine aerosol droplets. These droplets kill mosquitoes on contact as they fly through the target area. A primary benefit of ULV sprays is adulticide optimization. Very little product is necessary to treat large areas of land, typically less than one ounce per acre. This industrial mosquito spray method ensures effective coverage with minimal product use.

 

Are there any risks to using ULV spraying for mosquito control?

Numerous, peer-reviewed, articles indicate that industrial mosquito spray applications, including ULV spraying, do not pose a significant risk to humans or non-target insects.  In one study (Effects of single and multiple applications of mosquito insecticides on non target arthropods, Davis and Peterson, 2008), the researchers determined that “measurable and persistent biological effects on non-target arthropods, exposed to larvicides and adulticides applied via ULV sprayer would be small.   Also in an article published by the CDC (Human Exposure to Mosquito-Control Pesticides — Mississippi, North Carolina, and Virginia, 2005), the researchers measured the pesticide metabolite concentrations in urine of people pre-and post-application.  And it was determined that “ULV application in mosquito control activities did not result in substantial pesticide exposure to humans”.  In contrast, they were able to show an “association between home and/or work application of pesticides and pesticide metabolite concentrations”. In other words, individuals are far more likely to have pesticide exposure from home and work-related uses of pesticides than from ULV mosquito control efforts. 

In another study (A Human-Health Risk Assessment for West Nile Virus and Insecticides Used in Mosquito Management, Peterson et al., 2006), the researchers state, “Results from our risk assessment and the current weight of scientific evidence indicate that human-health risks from residential exposure to mosquito insecticides are low and are not likely to exceed levels of concern. Further, our results indicate that, based on human health criteria, the risks from WNV exceed the risks from exposure to mosquito insecticides.” This work is extremely important, as they were able to determine that the risk of adverse health impacts from contracting WNV is greater than the risk of health impacts from the pesticides used to control WNV vectors.  This is just a small sample of the published scientific literature regarding the potential harmful effects of our mosquito control applications.

These findings reinforce the safety and necessity of industrial mosquito spray efforts in public health applications.

ULV Spraying as Part of a Professional IMM Program ​

Industrial mosquito spray applications using adulticides are an effective and necessary tool to combat mosquito populations. When applied as part of an IMM program, the products are also utilized alongside other important strategies, including larval control, public education, and surveillance and disease testing. These solutions help make adulticide industrial mosquito spray applications more impactful while supporting more long-lasting results.

Professionals lean on the data compiled during surveillance and disease testing to inform their decision to intervene. Surveillance data is gathered through weekly trapping, and different types of traps can be used depending on the species that are being monitored. Once collected, each mosquito is identified and examined for disease. Understanding the unique species bionomics and disease threat helps professionals determine ULV spraying needs. Using science allows professionals to spray the right amount, at the right place, at the right time.

During the application process, GPS technologies play an important role. GPS tracking units create spray maps to help ensure even product coverage. This information can also be shared with the public. For successful control in large communities, ULV spray applications may be paired with residual “barrier” treatments via backpack applicators near homes and areas where mosquitoes tend to concentrate. Industrial mosquito spray equipment, such as trucks and aerial systems, can also be used to target adult mosquitoes across large areas of land.

The 4Ds: How Your Community Can Help Prevent Mosquito Breeding and Bites

It’s common to spend time in nature to relax and reset, but silent threats like mosquitoes can make this difficult and even dangerous. One of the reasons mosquitoes so often plague our outdoor activities is because they are highly efficient at reproducing. Anywhere water collects—from a stagnant pond to a tiny puddle in the sidewalk—can become an active breeding ground for mosquitoes. Therefore, community members play a vital role in the elimination of standing water, as well as the protection of themselves and their families from vector-borne pathogens. 

The best way to protect yourself when spending time outdoors is to remember the 4Ds. Watch the video below to learn how to learn about personal protection and property maintenance tips:

The 4Ds: Protect Yourself from Dangerous Mosquitoes

1. DEFEND

Consistently wear and reapply an EPA-approved repellent when outdoors

  • The safest and most effective repellents should contain 10-30% DEET (N,N Diethyl-meta-toluamide). 
  • Always follow manufacturer guidelines found on the label to ensure safe and optimal product use.
  • Review the EPA’s list of registered insect repellents – www.epa.gov/insect-repellents/find-repellent-right-you   
  • Keep dogs and cats safe, too, with preventative heartworm medication.

2. DRESS

Wear closed-toe shoes, light colors, and long sleeves and pants to keep your skin protected. 

  • Mosquitoes are more attracted to darker clothing. 
  • Comfortable, loose-fitting clothes are more effective at preventing mosquito bites.
  • Bare skin on your hands, ankles, face, neck, or other areas should be protected with mosquito repellent.

3. DRAIN

Mosquitoes require standing water to reproduce. 

  • Empty and prevent future water collection in outdoor tools and objects like tires, tarps, buckets, birdbaths, basketball goals, wheelbarrows, and lawn care equipment.
  • Ensure water can drain properly from gutters, flower pots, watering cans, rain barrels, low-lying ditches, and stormwater pipes and structures.

4. DUSK & DAWN

Limit spending time outdoors when mosquitoes are most active. 

  • Mosquitoes can become dehydrated in direct sunlight. 
  • During the day, mosquitoes typically linger in cool, shaded places like thick weeds, ivy, bushes, and wood piles.

Self-protection goes hand-in-hand with public education. Integrated Mosquito Management (IMM) programs are most effective when efforts are reinforced by the surrounding community. When state, regional, and municipal entities partner with a professional management company, they get access to industry experts who regularly present and work with health departments, churches, schools, libraries, senior homes, local clubs, and other groups to ensure they receive accurate information about the mosquito species, diseases, and tools used in the area. Educational resources can be disseminated through a variety of channels to inform citizens about up-to-date news, safety warnings, and mosquito prevention reminders. 

It’s important to remember that mosquitoes are not hindered by geographical boundaries. In fact, some species can travel many miles for a blood meal. When knowledgeable citizens work together, they can have a significant impact that benefits the entire community and help maximize the results of their local integrated mosquito management program.

Behind the Scenes Look: Utilizing Technology for Successful Surveillance & Disease Testing

Mosquito Surveillance & Disease Testing Technologies

Responsible mosquito management involves targeting mosquitoes at all stages of their lifecycle. A holistic, integrated approach is the most effective strategy to halt population growth and prevent the spread of deadly diseases while reducing environmental footprint.

surveillance and disease testing

Mosquito surveillance is the cornerstone of an integrated mosquito management (IMM) program. This begins with assessing breeding sites and eliminating mosquitoes at the larval stage. By analyzing population dynamics and species distribution, adult mosquitoes can be safely and effectively controlled. Proactive mosquito surveillance programs and data collection also allow scientists to optimize the use of insecticides and limit spraying to specific areas at precise times. These mosquito surveillance techniques reduce the chance of insecticide resistance, which can create additional challenges and expenses for stakeholders.

mosquito lab testing collecting dataHighly targeted, carefully formulated insecticides are used by experts to safely control mosquitoes and mitigate the risk of vector-borne disease transmission. Though insecticides are an impactful tool in mosquito management, it’s possible for mosquitoes to become resistant to them. According to the Centers for Disease Control and Prevention (CDC) if mortality drops to a rate of less than 90%, the mosquito population is considered insecticide resistant.

Insecticide resistance typically occurs during prolonged exposure to insecticides used during the management process. Continued use in moderately susceptible populations can result in the selection of resistant individuals and loss of insecticide sensitivity in certain areas—something that is particularly dangerous during large mosquito outbreaks following rainstorms, hurricanes, and other serious weather events. Insecticide resistance not only contributes to wasted time and resources but it also endangers communities through increased disease transmission.

mosquito lab testingThe best way to prevent insecticide resistance is ongoing mosquito surveillance and monitoring. IMM programs incorporate strategic mosquito surveillance and monitoring efforts throughout the management season to gather information about species bionomics, active periods, host preferences, and the presence of disease. This knowledge about local mosquito populations is used to determine the severity of a nuisance outbreak and inform control efforts. 

Scientists have multiple ways to collect information. Each method is selected based on the unique challenges a community is facing.

Mosquito Surveillance Traps

CDC Light Traps

These mosquito surveillance light traps, which were developed by the Center for Disease Control and Prevention, are considered the industry standard for mosquito surveillance and collection. Like the New Jersey light trap, it attracts many different species, but it is portable. A 6V battery powers a motorized fan that circulates carbon dioxide (CO2) as an attractant. Once they enter the mosquito surveillance trap, mosquitoes are sucked into a collection device. CDC traps are most effective when deployed at dawn and dusk when mosquitoes are most active.

BG-Sentinel Trap

This mosquito surveillance trap is designed to capture Aedes albopictus (Asian Tiger mosquito) and Aedes aegypti (Yellow Fever mosquito), each of which are known to carry diseases, including Dengue, Chikungunya, Zika virus, and Yellow Fever. Both species thrive in urban environments where they can breed in natural and artificial containers such as gutters, bird baths, watering cans, and outdoor equipment. The BG-Sentinel trap, which is made of a tarp-like material, utilizes an attractant to lure mosquitoes into a funnel. The funnel is outfitted with an electric fan that pulls them into a net where they will remain until collection.

mosquito trapsGravid Trap

Gravid traps are designed to catch Culex mosquitoes, such as Culex tarsalis or Culex pipiens. These species are capable of spreading West Nile virus, St. Louis Encephalitis, and both Western and Eastern Equine Encephalitis. Each gravid trap is filled with stagnant water containing organic matter like grass or hay to mimic natural breeding grounds. As Culex mosquitoes approach, they are sucked by an electric fan into the trap for future collection.

New Jersey Light Trap

The New Jersey light trap is effective at capturing a wide spectrum of mosquito species. It is typically used as a permanent mosquito surveillance tool that’s mounted and powered by an outlet in target areas. The New Jersey light trap is a beneficial tool to support IMM programs—it is capable of collecting large quantities of local mosquitoes for scientific analysis and data collection. 

Lab Disease Testing

PCR Tests 

Clinical tests are commonly used in the industry to identify mosquito-borne diseases. PCR tests, for example, allow laboratory technicians to detect different bacteria or viruses that have been transmitted by mosquitoes. Though PCR tests are also used to detect Covid-19, it’s important to note that mosquitoes do not spread the SARS-CoV-2 virus.

RAMP® WNv Tests

RAMP tests are also widely used in the industry. This highly-sensitive test is designed to detect West Nile virus in mosquitoes. A RAMP test can be conducted quickly and efficiently in-house, making it particularly useful following hurricanes and weather events.

Monitoring for Insecticide Resistance

CDC Bottle Bioassay

One of the most important tools when monitoring for insecticide resistance is the CDC Bottle Bioassay. As part of the testing process, bottles are coated with a diluted pesticide solution and then paired with a control group. Female adult mosquitoes are deposited into each bottle, where they are exposed to stressful conditions. Mortality data is then collected and analyzed by scientists for evidence of insecticide resistance. 

Larval Cup Bioassay

Larvicides are central to proactive mosquito management programs, and resistance is less common; however, it can still occur. Larval control agents work through either ingestion or contact with the target host, depending on the product used. Like the bottle bioassay process, cups are coated with bacterial larvicides like Bacillus thuringiensis israliensis (Bti), Bacillus sphaericus (Bs), or Spinosad and examined for mortality data.

GPS/GIS Technology

Modern GPS/GIS technologies have made it possible to gather large amounts of data for site mapping, disease tracking, and analysis. This information can be compared over time to identify trends or patterns that help advise the direction of management programs and ensure ongoing compliance with regulatory standards. 

Now, GPS technologies are being integrated into advanced aerial equipment. VDCI’s state of the art drones give technicians a birds-eye-view of target sites for more streamlined site surveillance and mapping, as well as more precise pesticide applications. Likewise, advanced drones allow experts to observe and treat areas that are dangerous, like swamps and wetlands, or more private, like HOAs and other large communities.

drone surveillance

Scientists have many advanced tools at their disposal for trapping, species identification, and disease testing, but the most valuable approach is preventative management. Proactive mosquito surveillance, monitoring, communication, and stakeholder education can help experts identify and quickly mitigate disease risks before a community is impacted. VDCI has the experience, necessary mosquito surveillance equipment, industry-leading technologies, and capabilities to handle all of your mosquito surveillance and disease monitoring needs.
