West Nile spraying scheduled for Buffalo, East Buffalo and Lewisburg

The Northumberland County Mosquito-borne Disease Control Program, in coordination with the Department of Environmental Protection, will be conducting an ultra-low volume (ULV) mosquito control operation to reduce high populations of mosquitoes capable of transmitting West Nile Virus on September 19th, 2018 in parts of East Buffalo and Buffalo townships and Lewisburg Borough. West Nile virus activity as well as high populations of adult nuisance mosquitoes have been detected in the area. Certain mosquito species carry the virus, which can cause humans to contract West Nile encephalitis, an infection that can result in an inflammation of the brain. According to the Pennsylvania Department of Health, all residents in areas where virus activity has been identified are at risk of contracting West Nile encephalitis. The treatments will be administered via truck-mounted equipment, spraying residential and recreational mosquito habitat. The product used will be Aqua Duet at a rate of 0.66 ounces per acre. The product is designed to provide quick, effective control of adult mosquito populations. Weather conditions and other unexpected events could delay or cancel this spray operation. If conditions remain unfavorable, the spray will be postponed until weather permits.Provided there are no unforeseen circumstances or adverse weather, the spray will begin at dusk.
