County Plans to Kill Mosquitoes With Spray Tuesday Night in Penn Valley

The Montgomery County Health Department plans to spray pesticide at two Penn Valley locations Tuesday night in the hopes of denuding the mosquito population and, thus, the risk of West Nile virus, according to its news release Friday.

Population sampling by the county and by the state Department of Environmental Protection showed particularly high mosquito concentrations at the waste-transfer station and public works complex on Woodbine Avenue and at the intersection of Flat Rock and Marywatersford Roads, the department announced. Surrounding streets may be affected, too.

Those areas will be sprayed between 8:30 p.m. and 11 p.m. Tuesday—or the same time Wednesday, if it rains Tuesday night.

The spraying will take place from the ground, not by aircraft, the department said. The concentration is 1.5 fluid ounces per acre. The EPA website on mosquitoes describes the pesticides used.

Township residents who see standing water in which they believe mosquitoes could be breeding should call the health department at 610-278-5117.
