Mosquito Control

The Ballwin Public Works Department will resume its annual attack on mosquitoes on Monday, May 18, 2020 and will continue into September 2020. Fogging will begin at 8:30 p.m. when the adult mosquitoes are most active.  The entire City will be fogged on a weekly basis.  Wards not fogged due to rain, excessive wind speed, or holidays will not be fogged that week. The following schedule will be followed:

Mondays – Ward 1 (click here for map)

Tuesdays – Ward 2 (click here for map)

Wednesdays – Ward 3 (click here for map)

Thursdays – Ward 4 (click here for map)

Fridays – No fogging 

EPA approved water based “Aqua Kontrol 30-30"  is the insecticide ejected into the air to kill flying adult mosquitoes.  The City's two licensed operators are Certified Public Operator Applicators by the Missouri Department of Agriculture. 

St. Louis County Department of Health has compiled suggestions to reduce mosquito populations.  For more information visit their website at www.stlouisco.com, the Centers for Disease Control at www.cdc.gov, or the National Pesticide Information Center at www.npic.orst.edu

If you have a bee hive, please call the Ballwin Public Works Department. The streets that we know have bee hives will be fogged at a later time, once bees have returned to their hive.
