The latest lab report has confirmed the presence of West Nile virus (WNV) in Culex mosquitoes in six areas of Knox County. Following Centers for Disease Control and Prevention (CDC) protocol, the Knox County Health Department (KCHD) will spray for mosquitoes in these areas on Tuesday, Aug. 22 and Thursday, Aug. 24 between 9 p.m. and midnight, weather permitting, to reduce the Culex mosquito population and the risk of WNV spreading to humans. Signs will be posted in the affected neighborhoods to alert residents, who are asked to stay inside during spraying and keep pets inside or in the backyard. Spray area details are below, maps are included.


“While it doesn’t occur every mosquito season, it’s not altogether uncommon for this many mosquito pools to test positive for West Nile virus at once,” said KCHD Environmental Health Director Ronnie Nease. “Mosquito season is here, and we need the community to do their part to help reduce mosquito-borne disease by wearing mosquito repellant and by dumping any standing water on their property every week.”


To prevent mosquito bites and reduce mosquito habitats, officials recommend the following:

  • Apply repellants to skin often; these can include lotions, liquids or sprays. The CDC recommends the use of repellants that contain DEET, Picaridin, oil of lemon eucalyptus or para-menthane 3, 8-diol, and IR3535. The duration of protection varies by repellant; read labels on products to determine when reapplications are necessary for optimal protection.
  • Wear long, loose and light-colored shirts and pants and wear socks.
  • Treat clothing with permethrin or purchase pretreated permethrin clothing.
  • Dispose of, regularly empty, or turn over any water holding containers on your property such as tires, cans, flower pots, children’s toys or trash cans.
  • To prevent breeding in large water-holding devices, including bird baths or garden pools, use larvicides such as mosquito torpedoes or mosquito dunks. If used properly, larvicides will not harm animals.

To reduce the risk of mosquito-borne disease, KCHD conducts a West Nile virus control program during the summer and fall months. As the weather warms each spring, public health professionals begin a weekly process of trapping and testing mosquitoes for WNV, a mosquito-borne disease which can infect humans, horses and birds. From March until the first frost, KCHD also uses larvicides in areas with standing water to prevent mosquito proliferation. These efforts are in addition to KCHD’s work to assess and monitor for Zika virus disease. More information is available by calling 865-215-5200 or visiting
