Mosquito Program

This is a seasonal program that begins around the end of April or beginning of May, and consists of both larviciding and fogging.     

Larvicides are applied to breeding habitats to kill mosquito larvae. Killing thousands of mosquito larvae in a water source with a larvicide is much more effective than trying to eliminate them as adults with fogging.  Fogging is done throughout the Hamilton County area until the end of summer when mosquitoes are no longer a problem.

The container-breeding mosquito species are the primary disease carrying mosquitoes in our area. Preventing water from collecting in containers, such as buckets, cans, and clogged gutters prevents mosquitoes from reproducing.  Eliminating the water sources that breed mosquitoes is the most effective way to prevent mosquitoes.

Hamilton County residents may call the Environmental Health Office when fogging is required for a severe mosquito nuisance.  Mosquito fogging is done by sectors. We have a phone number specifically for mosquito fogging requests. Please call (423) 209-8117. Messages are retrieved every afternoon and added to the list for fogging.
