Mosquito Control

The City of Chesterfield contracts with St. Louis County Department of Health to provide mosquito control services to the City. These services include the treatment of mosquito breeding sites on public land and spraying to control adult mosquitoes. Breeding sites are monitored on a regular basis. The decision to spray for adult mosquito control is primarily based upon mosquito surveillance information and other factors including the human health threat from West Nile virus.

Residents who have mosquito complaints should contact the St. Louis County Health Department directly at 314-615-0680. They will monitor the areas brought to their attention and will add to their spraying route as necessary.

Residents who desire information on the general location of mosquito spraying in St. Louis County can call the Health Department's hotline at 314-615-4284 (615-4BUG).
