Help Keep Mosquitoes Under Control in Your Hometown

May 15, 2020



Now that the weather is warming up, the City of St. Peters Health Department is doing everything they can to reduce the mosquito count in our area. Mosquitoes start laying eggs this time of the year and carry a variety of dangerous diseases. By controlling the mosquito population and breeding grounds, we can keep our Hometown healthy.


Our Health Department uses one of the safest mosquito adulticides available. The chemical is a pyrethroid and emulates a natural chemical typically found in chrysanthemum flowers. This chemical is also approved by the U.S. Environmental Protection Agency. The City sprays regularly, weather permitting (spraying during windy or rainy conditions is ineffective).


What You Can Do to Help: While the Health Department has a variety of tools for dealing with pests like mosquitoes, you can help contribute to mosquito control to


1. Dump any standing water on your property. Water collecting in containers or puddles is prime real estate for mosquitos to breed. All it takes is a bottle cap of water for mosquito eggs, and after a week they develop into full-grown adults. It’s important to actively look for any water collecting on your property. Once a week, empty and scrub any items that contain water on your property. Either leave open containers upside down to promote drainage of any excess water, or empty them and move them to a place where they cannot collect water. Water bowls left outside for pets should be emptied daily.


2. Tightly cover water storage containers. If you have any kind of container meant to hold water, such as buckets, cisterns or rain barrels; make sure they are tightly sealed so that mosquitoes don’t have access to the moisture. If the container does not have a lid, use wire mesh with holes smaller than an adult mosquito to keep them out.


3. Request a free property inspection (RESIDENTS ONLY). If you’re not sure if your property has any potential problem areas for mosquitoes, we can help. St. Peters Residents can request a property inspection from the St. Peters Health Department. A city official will inspect your property for any areas of concern, and provide you tips to keep mosquitoes from breeding near your home. Request an inspection by contacting the St. Peters Health Department at 636-477-6600, ext. 1465.


4. Report a concern to the Citizen Action Center. If there’s a problem area you would like to report to the St. Peters Health Department, we’re all ears. Treating areas for mosquitoes is one of the free services we provide to our residents, and we’ll listen to any concerns you may have. Contact the Citizen Action Center at 636-477-6600, ext. 1225. A health official will respond to your concern within a few days.
