Mosquito Control

Our Mosquito Abatement Program
The mosquito abatement program runs May through September. The Village of Wauconda contracts with Clarke Mosquito Control to administer our Environmental Mosquito Management™ Program. It is an extensive integrated pest management plan that includes inspections, surveillance of mosquito populations, and treatments for both larval and adult mosquito control. Our program is based on disease prevention. Our program with Clarke does not eradicate the mosquito population, but controls it to prevent West Nile Virus.

Surveillance & Monitoring
Clarke Mosquito Control conducts 10 inspections during the mosquito season of up to 118 sites within the village for mosquito breeding. GIS System mapping and aerial surveys from a helicopter assist in determining possible mosquito breeding sites.

Clarke employs a Targeted Mosquito Management System computer database and site management system to track the information needed to administer the program for the Village of Wauconda. Records are kept that track the sites that produce larvae, the various species of mosquitoes found, the type of habitat developing larvae, plus other pertinent data.

Larval Control
According to the Center for Disease Control, larval control is an effective way to reduce mosquito populations. Larval treatments are administered to prevent the larva from developing into an adult mosquito. The sites receiving larval treatment are determined from the surveillance and monitoring activities. Larvicide applications are made on foot, by vehicle, or through the use of Clarke’s helicopter.

In addition, Clarke treats 733 storm sewer catch basins, inlets and manholes with a larvicide treatment 4 times during the mosquito season. The treatment is a 30 day slow release insecticide and is started in early summer to prevent larval development.

Clarke also responds to calls from residents or staff for additional site inspections.

Adult Mosquito Management
Generally speaking, 3 community wide adulticiding treatments (spraying) are conducted every year. Three treatments are included in the contract price. Additional treatments are available at an additional cost. There have been some years in which the Village did spray more than 3 times due to the threat of West Nile Virus. The results of this year’s surveillance and monitoring will determine the need for adulticiding treatments this year. It is important to note that spraying provides a quick knock-down of mosquito populations; however, it is considered a last line of defense. Larval control is key to controlling mosquito populations.

West Nile Virus
The Culex pipiens, or house mosquito, is the predominant species of mosquito that carries the West Nile Virus. It is a mosquito that flies and feeds at dusk or in the evening. It tends to breed in stagnant water such as that found in containers - old tires, birdbaths that haven’t been cleaned, ditches with decaying leaves or grass, boats with rainwater, pools that haven’t been cleaned or do not have chlorine, and other stagnant waters. Wetlands are not considered a source of Culex mosquitoes because the water in a wetland is clean. In addition to the mosquito control conducted by Clarke, residents are also asked to eliminate any standing water on their properties. Also, when outdoors, residents are encouraged to apply insect repellent that includes DEET or picaridin, according to label instructions. And if possible, shoes, socks, long pants, and a long-sleeved shirt should be worn.

The Aedes mosquito is the most common mosquito and that is the mosquito that hatches after a rainfall. However, it is not considered a vector of the West Nile Virus. It is considered a “nuisance” mosquito.

Clarke Mosquito Control has a hotline established to answer all residents’ questions and concerns. The number is 1-800-942-2555. Please feel free to call them anytime for additional general information or for more specific information regarding your particular subdivision. They can give you detailed information about the numbers and types of mosquitoes found in your area and the methods they are using to control them. You can also call them to be placed on a notification list for sprayings.
