The Cheyenne-Laramie County Health Department in conjunction with the Cheyenne Weed and Pest Department will begin aerial larvacide work the week of July 8th. Spokesman Gary Hickman says fixed wing aircraft will fly the major drainage areas of Laramie County including municipal sewage lagoons, ponds, stock reservoirs and lakes in an effort to eliminate the mosquito vector that carries West Nile Virus.

Hickman says the larvacide is a biological agent that targets only mosquito larvae in their aquatic life cycle. The larvacide is harmless to animals and livestock. Flights are generally flown in the early morning hours on calm days. For more information, contact the Cheyenne-Laramie County Health Department at 307-633-4090.
