< The Knox County Health Department operates a West Nile Virus control program from April to November each mosquito season. Our goal is to reduce the public health threat of West Nile Virus caused by mosquitoes.
Knox County offers a broad spectrum of services to help control the spread of the virus and the mosquito population. Educating the public regarding mosquito control and how to help reduce the incidence of mosquito bites is very important.
Mosquito Control employees are available to conduct meetings for homeowner associations, community and civic groups, health fairs, or any group interested. For more information, contact (865) 215-5200.

Environmental investigations are conducted in response to complaints filed with the Health Department. Mosquito Control Technicians investigate the complaint to determine if mosquito breeding is occurring. If breeding is occurring a plan is developed and implemented to correct the complaint. The mosquito-breeding site could be removed or an environmentally safe product is applied to the water, which controls the mosquito breeding.
Surveillance is used to determine the species and number of mosquitoes in different locations throughout Knox County and is utilized to determine if West Nile Virus is present.
If WNV is found in an area, Knox County follows CDC guidelines for spraying.
Each citizen can help control mosquitoes on their property and in their community by conducting surveys to determine standing water sources. Removing items that can retain water will help reduce the mosquito population. Old tires, buckets, cans, wading pools, unattended birdbaths, wheelbarrows, gutters and ornamental ponds can be sources for mosquito breeding. Shrubs, trees and lawns need to be trimmed and mowed on a regular schedule to help reduce areas where adult mosquitoes can go and rest. The trees and shrubs can also be sprayed with Malathion or Sevin, which can be purchased at hardware stores, to help reduce the adult mosquito population. (Always apply chemicals according to label)
