LFCHD To Spray For Mosquitoes Next Week

LEXINGTON, Ky. (LEX 18) — The Lexington-Fayette County Health Department has reported a probable case of West Nile virus.

As a result, the health department will conduct mosquito-spraying activities in the pre-dawn hours Thursday morning in portions of the 40502, 40507 and 40508 ZIP codes.

The route will focus on the downtown areas between Euclid Avenue and Main Street, including Woodland Park. This is the first reported probable human case of West Nile Virus in Fayette County this year.

West Nile Virus can be spread to humans through the bite of an infected mosquito. Symptoms include fever, headache, body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach and back. People experiencing these symptoms should consult with their healthcare provider.

Spraying will be done between the hours of 3 a.m - 6 a.m. on Thursday. For spraying to occur, the wind speed must be less than 10 mph, the temperature must be greater than 55o F and there can be no rain or dense fog.

The mosquito spray used by the health department only affects adult mosquitoes that are in the air at the time of spraying. The health department uses Duet, an EPA-approved agent that features a component that stimulates resting mosquitoes in trees and foliage, causing them to fly into the air and come into contact with the spray’s mosquito-killing agent, sumithrin. Duet has been rigorously tested for human and animal safety and is registered for outdoor residential and recreational areas.

Lexington residents can also take steps at home to fight mosquitoes:

  • Mosquito-proof your home and yard. Fix or install window and door screens. Mosquitoes lay their eggs in standing water. Cover or eliminate empty containers with standing water. Limit the number of places around your home for mosquitoes to breed by getting rid of items such as tires, buckets, barrels and cans. Refresh the water in your pet’s water dishes and birdbaths at least every five to seven days.
  • Be aware of peak mosquito activity times. The twilight hours around dusk and dawn are times of peak mosquito activity. Use insect repellent when outdoors especially during peak activity times, including early morning hours. Look for EPA-labeled repellents containing active ingredients, such as DEET, Picaridin (KBR3023) or oil of lemon eucalyptus (p-menthane 3,8-diol). Apply repellent according to label instructions. When weather permits, wear long sleeves, long pants and socks outdoors. Mosquitoes can bite through thin clothing, so spraying clothes with repellent containing permethrin or another EPA-registered repellent helps prevent bites.
