Multiple Pennsylvania Counties Conduct Mosquito Spraying for West Nile Virus

Several counties across the United States are conducting mosquito spraying operations to combat high populations of mosquitoes carrying the West Nile Virus, which can cause serious illness such as West Nile encephalitis. In Pennsylvania, Bucks County is conducting ultra-low volume spraying in Warminster and Warrington townships, while Franklin County plans spraying in Hamilton Township and Chambersburg Borough, with both counties advising residents to stay indoors during treatment and noting weather may delay operations. Montgomery County is also spraying in Whitpain Township with similar precautions and recommendations for residents to eliminate standing water to prevent mosquito breeding. In Texas, the City of Arlington is performing targeted ground spraying based on positive mosquito trap samples, using a water-based permethrin product considered safe by the EPA, with spraying conducted at night to reduce infected adult mosquito populations rapidly. All efforts emphasize the importance of community participation in reducing standing water and following safety guidelines during spraying times to protect public health from West Nile Virus exposure.
