Mosquito Abatement

The Village’s Mosquito Management Program is completed by Clarke Mosquito Management, Inc. for the areas in DuPage County and Des Plaines Valley Mosquito Abatement District for the areas in Cook County. Mosquito abatement services include surveillance, monitoring, larva and adult control (as needed). Services begin in May and continue through September.

Clarke Mosquito Management is treating Village catch basins with larvicides that contain naturally derived active ingredients. The product is named Natular and contains Spinosad, a product derived from a naturally occurring soil bacterium. Spinosad alters the function of insect receptors. Natular is the first larvacide evaluated as a reduced risk product by the EPA. Clarke is scheduled to utilize Natular in catch basin treatments during the 2024 season.

Residents are encouraged to check the Personal Protection Index (PPI) on the Health Department’s website for the most up-to-date information on West Nile virus (WNV) activity. 

WNV activity generally decreases in the fall when cooler temperatures arrive and especially after the first frost of the season. Additional information and resources on WNV prevention are available at and
