MosquitoThe City of St. Peters’ integrated approach to mosquito abatement includes public education, larviciding, adulticiding and natural control.



Larviciding is the method of adding an environmentally friendly time-release growth hormone to standing water that prevents mosquito larvae from becoming adults. The City usually begins larviciding in mid-April in City parks and public rights-of-way that contain standing water.




Mosquito PatrolAdulticiding


Adulticiding, or killing adult mosquitoes, is accomplished with a cold aerosol, ultra-low volume “fogging” machine, operated by public health specialists licensed by the Missouri Department of Agriculture. All areas of the City are sprayed on a regular basis. The City will spray extra in the parks before outdoor movies and concerts and other special events, and also on the Thursday and Friday preceding the July 4th holiday weekend.

A new spray tool allows City workers to fog storm drains and culverts where mosquitoes hide and overwinter to lower the population of early spring adult mosquitoes.




Natural Mosquito Control

Natural control efforts are useful when possible. Bats, purple martins and some fish (goldfish, for example) eat mosquitoes, so the City installs bat and purple martin houses in parks and public grounds and occasionally stocks mosquito-consuming fish in ponds and wet storm water basins. The City also enforces weed cutting on vacant ground to minimize mosquito hiding and resting places.




How Residents Can Help

Residents truly make a difference in the City’s fight to limit the mosquito population, prevent the spread of related disease and foster a healthy environment. Standing water is the mosquito’s home, so removing places where these pests lay eggs in your own backyard is key.
There are many places around the perimeter of your home where standing water can be found such as tree stumps, clogged gutters or downspouts, clogged storm drains, flat roofs, pool covers, trash cans, wheel barrows, ornamental ponds, toys, etc. Check your yard and eliminate places for mosquitoes to breed. Be sure to change the water in birdbaths and pet bowls frequently.

Mosquitoes can develop from eggs to adults in as little as seven days and very little water is needed to become a home to mosquito eggs—even a tray under a flowerpot can hatch mosquitoes. Therefore, it’s important to actively remove standing water from your property.




West Nile Virus

St. Peters proactively fights the mosquito population and asks residents to help because mosquitoes are not only annoying, but some mosquitoes spread diseases like the West Nile virus which can be a serious, life-altering, and even fatal disease.
