ORIGINAL STORY Aug.18, 2017: Mosquitoes carrying West Nile virus have been detected in six more areas of Knox County after testing by the Knox County Health Department.

Spraying has been scheduled in those affected areas on Tuesday, Aug. 22 and Thursday, Aug. 24 between 9 p.m. and midnight, weather permitting. Follow-up spraying is scheduled for Tuesday, Sept. 5 and Thursday Sept. 7.

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.

“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.”

Mosquito prevention tips

• 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.
