Lancaster County Mosquito Spraying Set for 8/31/2021

See the important message from the Mosquito-borne Disease Control Program Coordinator of Lebanon & Lancaster Counties below.


The Lancaster County Mosquito-borne Disease Control Program will be conducting an ultra-low volume (ULV) mosquito control operation in response to evidence of localized transmission of West Nile Virus in Manheim Borough and Manheim Township, Lancaster County.  The spray will be conducted on August 31, 2021 within Manheim Borough and Manheim Township, starting at dusk.  The treatment will be administered via truck-mounted equipment, spraying residential and recreational mosquito habitat.  The equipment dispenses AquaDuet at a rate of 1.00 ounces per acre.

The product is designed to provide quick, effective control of adult mosquito populations. The application material has a very low toxicity profile to mammals and will have negligible impact to non-target insects and the environment.

Weather conditions and other unexpected events could delay or cancel this spray operation. If conditions do not allow application on August 31, 2021, information will be forwarded regarding a new spray date as soon as it is available.

Questions or concerns can be directed to Olivia Bingeman, Program Coordinator, at 717-277-5275 ext. 112 or For more information about West Nile virus and the state's surveillance and control program, please visit
