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

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 remembering the 4Ds:

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

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

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 surveillance and data collection also allow scientists to optimize the use of insecticides and limit spraying to specific areas at precise times. These 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 monitoring. IMM programs incorporate strategic 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 trapsCDC Light Traps

These 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 trap, mosquitoes are sucked into a collection device. CDC traps are most effective when deployed at dawn and dusk when mosquitoes are most active.

mosquito trapsBG-Sentinel Trap

This 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 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.

mosquito trapsNew 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 device 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. 

PCR Tests 

Clinical tests are commonly used in the industry to identify 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.

lab testing

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.

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.

Scientists have many advanced tools at their disposal for trapping, species identification, and disease testing, but the most valuable approach is preventative management. Proactive 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 equipment, industry-leading technologies, and capabilities to handle all of your mosquito surveillance and disease monitoring needs.

The American Mosquito Control Association (AMCA) started the Young Professionals (YP) Program to increase the participation of students as well as professionals new to the mosquito industry (~5 years or less). The YP group provides these AMCA members with opportunities to build relationships with each other as well as network with experienced professionals. The main outlet for this engagement is the annual AMCA meeting. 2016 marked the 3rd year of YP activities, which included an informal dinner, a fieldtrip, and the highlight of the week – the YP symposium! The roundtable format encourages YPs to speak with experts in different mosquito-related fields to gain unique perspectives and new skills.

While the annual meeting is a great opportunity, it can be difficult for YPs to attend for various reasons – with budget related obstacles topping the list. To help bring a greater number of YPs to the annual meeting, a Shadowing Program was implemented in 2016. The program asked industry partners to support AMCA YPs with travel stipends, allowing for greater attendance, and VDCI was eager to partner with the program.
