The City of Wood Dale contracts with Clarke Environmental to provide mosquito abatement services for the Wood Dale community. The contractor performs multiple city-wide sprayings each year as part of an integrated pest management plan that includes inspections, surveillance of mosquito populations, and treatments for both larval and adult mosquito control. The program does not eliminate all mosquitoes, but controls the population to prevent the spread of West Nile Virus. 

City of Wood Dale residents should be aware of new state regulations regarding pesticide applications on public rights-of-way that took effect January 1, 2025. Under Public Act 103-0976 (The Pesticide Application on Rights-of-Way Notification Act), we are implementing enhanced notification procedures to keep our community informed about pesticide applications.  Click here to learn more.

As of January 1, 2025, City of Wood Dale must provide written notice at least 24 hours before any pesticide application to public rights-of-way, including:

Larvicide Products Being Used (Mosquito)

These EPA-registered larvicides and adulticides can be safely applied in residential areas. Residents may remain outside during application, as there are no special safety precautions required according to the product labels.

• Disease-causing agents in mosquito populations
• Mosquito-borne diseases affecting humans or animals
