Knox County Health Department (KCHD) will be spraying for mosquitoes in eight areas on Thursday, Sept. 6, between the hours of 9 p.m. to midnight, weather permitting. Two new surveillance sites, in the Island Home and Vestal areas, have lab confirmation of the presence of West Nile Virus (WNV) in mosquitoes. The other six sites are repeat sprayings from two weeks ago as specified in Centers for Disease Control and Prevention protocol. (CLICK HERE for maps of the areas to be treated.)
A total list of spray areas and streets is included below. Signs will be posted in the affected areas to alert residents, who are asked to stay inside during spraying and to keep pets inside or in the back yard. Follow up spraying for Island Home and Vestal will be done two weeks following, and a notice will be sent out at that time.
“To date, Knox County has had no confirmed cases of West Nile Virus in humans,” said Ronnie Nease, KCHD’s Environmental Health director. “By spraying to reduce the population of mosquitoes, we hope to reduce the risk of mosquito-to-human transmission. It’s still important to wear the appropriate clothing and repellant when you are outside and mosquitoes are present.
There are 21 species of mosquitoes present in Knox County. The Culex species of mosquito is the main carrier of WNV. It hides in shady areas during the day but comes out at dawn and dusk for a blood meal in order to reproduce. The striped Asian Tiger mosquito that is so aggressive is not known to carry West Nile Virus. The public is reminded to stay vigilant about reducing standing water on their properties, which is where mosquitoes breed.
