📣Just a reminder:📣
As noted in our City newsletters and Ballwin Life Magazine, the City of Ballwin's Public Works Department is NOT fogging for mosquitos this year.
For several years, the Public Works Department provided a weekly application of mosquito adulticide control spray in residential areas throughout the City from late May to mid-September.
In August 2025, the Board of Aldermen voted unanimously to discontinue this service. They noted adulticide services were not effective in reducing the mosquito population and instead harmed other, beneficial insects.
The City does still contract with St. Louis County Vector Control Services for control of mosquito larvae, and those trucks will fog if trap sites collect high numbers of larvae.
To reduce mosquitos in your yard:
• Keep your lawns mowed and rain gutters clean
• Remove standing water on your private property
• Once a week, empty and scrub, turn over, cover, or throw out any items that hold water like tires, buckets, planters, toys, pools, birdbaths, flowerpot saucers, or trash containers. Mosquitoes lay eggs near water.
• Don’t let water accumulate in rain gutters, piles of leaves, or in vegetation
• Remove sources of standing water in and around your home in plant pot saucers, pool tarps, etc.
• Tightly cover water storage containers (rain barrels, etc.)
• For containers without lids, use wire mesh with holes smaller than an adult mosquito
