The Bucks County Department of Health (BCDH) Mosquito Disease Control Program will conduct an ultra-low volume (ULV) mosquito control operation on Wednesday August 19th at 8:00 PM in Bristol Borough, Bristol Township, and Falls Township to reduce high populations of nuisance mosquitoes and mosquitoes capable of transmitting West Nile Virus.
🚗The treatment will be administered using truck-mounted equipment to treat mosquito habitats in residential neighborhoods and park areas. Trucks used during the application are identified by Bucks County seal logos displayed on the doors. The equipment dispenses Duet at a rate of 0.75 ounces per acre. This product is designed to provide quick, effective control of adult mosquito populations. The application has very low toxicity to mammals and is expected to have negligible impacts on non-target insects and the environment.
📍Treatments will occur in Bristol Township areas bounded by Hood Blvd., New Falls Rd., S. Oxford Valley Rd., and Fairbridge Dr. Areas bounded by Mile St., Saybrook Dr., Veterans Hwy. (Rt 413), Newport Rd., Dixon Ave., and Arthur Ave. Lastly, areas bounded by N. Radcliffe St., Monroe Ave., Riverview Ave., Green Ln., Ash Ave., Wood Ave., and Pitt Ave. will be treated.
📍Treatments may occur in Bristol Borough areas bounded by Radcliffe St., Green Ln., Ash Ave., and Landreth Rd.
📍Treatments will occur in Falls Township areas bounded by Warwick Rd., Hood Blvd., and New Falls Rd.
Certain mosquito species can carry West Nile virus, which may cause West Nile encephalitis, an infection that results in 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 infection.
⛈Weather conditions and other unexpected events could delay or cancel this treatment operation. If conditions do not allow application on August 19th, Thursday August 20th, will serve as the back-up treatment date.
ℹYou can help protect yourself and your community from West Nile Virus by getting rid of standing water around your home. Mosquitoes can breed in even small amounts of water found in items such as flowerpots, buckets, toys, and clogged gutters. Using insect repellent and wearing long sleeves and pants, especially during dawn and dusk, can also help prevent mosquito bites.
