Mosquito Abatement

Clarke Mosquito

The Village of Westmont contracts with Clarke Mosquito to perform annual mosquito abatement. Clarke is a global environmental products and services company. Clarke strives to develop and deliver environmentally responsible mosquito control and aquatic services to help prevent disease, control nuisances and create healthy waterways. Following is information regarding some of their products and system delivery methods:

  • Clarke’s program includes larviciding using Natular and adult mosquito control using the product Merus.  Both products have naturally derived active ingredients, approved for use in and around organic farms, and are Organic Materials Review Institute (OMRI) Listed. Clarke believes this combination is the most effective way to prevent nuisance and disease-carrying mosquitoes from disrupting the lives of our residents.
  • The adulticides used to control flying adult mosquitoes are applied early evening and into the night when beneficial insects are at rest, limiting exposure. 
  • All products used by our program are registered for use in residential areas by the EPA and are recommended by the EPA and CDC to mitigate outbreaks of mosquito-borne disease.
  • The products in Clarke mosquito control efforts have not been associated with any increased risks of COVID-19. 
  • Clarke follows integrated pest management (IPM) strategies which are best practices that minimize the impact of mosquito control on the environment and are driven by science and extensive research.

DuPage County "Fight the Bite" Program

To help citizens protect themselves against West Nile Virus (WNV), the DuPage County Health Department has created a Personal Protection Index (PPI) that will inform residents of the amount of WNV activity in the county, as well as prevention steps that are recommended.

When activated, residents should follow the 4 Ds of prevention that coincide with the PPI risk level:


Drain any items that collect standing water around your home, yard or business. Scrub and refill pet water dishes and bird baths daily.


Use an insect repellent containing DEET when outdoors and reapply according to directions.


Wear long pants, long sleeves and closed toe shoes when outside to cover the skin.

Dusk & Dawn

Wear repellent outdoors during these prime times for mosquito activity.
