Knox County Tennessee

West Nile Virus Control Program (Vector Control)

Environmental investigations are conducted in response to complaints filed with the health department. Mosquito control technicians will investigate to determine if mosquito breeding is occurring. If larvae are found, a plan is developed and implemented to correct the issue. The mosquito-breeding site could be removed or an environmentally-safe product could be applied to the water, which controls mosquito breeding.

Educating the public regarding mosquito control and how to help reduce the incidence of mosquito bites is vitally important. Information is available on this website. In addition, mosquito control employees are available to speak to homeowner associations, community and civic groups, health fairs, or any group interested. For more information, call 865-215-5200.
