Each year, the St. Louis County Department of Health sprays for mosquitoes in Des Peres on Thursday evenings, May through October as needed. Effort is concentrated on pretreatment - larva control.
Spraying for adult mosquitoes is on a complaint basis only.
Source reduction is encouraged and homeowners and businesses can help by eliminating breeding sites on their property. If you need fogging services in your neighborhood, please contact St. Louis County Health at 314-615-0680 or the Des Peres Department of Public Works at 314-835-6134.
