Health department to spray for mosquitoes July 23

To help control mosquitoes, the Lexington-Fayette County Health Department will conduct mosquito-spraying activities in the pre-dawn hours on July 23 in parts of the 40505 and 40511 ZIP codes. The spraying is due to a high mosquito population found in a monitoring trap in the 40505 ZIP code region. To provide adequate spray coverage of the area, portions of 40511 ZIP code will also be sprayed.

Spraying will be done between 3-6 a.m. Tuesday. 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.

The health department also conducts surveys in neighborhoods around Lexington to identify standing water problems that can serve as a location for mosquitoes to lay their eggs. Elimination of standing water is the ultimate goal, but in areas where standing water cannot be eliminated the water can be treated to kill mosquito larvae with a chemical called a larvicide.

To report a standing water problem in your neighborhood, please call the health department’s Environmental Health section at (859) 231-9791.
