Senior Environmental Health Specialist Nathan Powell conducted an interview with GTV3 at McConnell Springs to provide information about how LFCHD helps control mosquitoes. Powell also demonstrated how EH kills mosquito larvae with a chemical called a larvicide.

To help control mosquitoes, the Lexington-Fayette County Health Department’s Environmental Health (EH) team conducts mosquito-spraying activities throughout the summer. Spraying starts in the evening hours when mosquitoes are most active. For spraying to be held, 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.

Nathan Powell discusses how his team works to control mosquitoes.

EH 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. The mosquito spray used by the health department only affects the mosquitoes that are in the air at the time of spraying.
