The Department of Environmental Protection will apply treatments the evening of Tuesday, Aug. 28, in portions of Yeadon, Darby and Lansdowne boroughs in Delaware County, to control adult mosquito populations. In the event of rain, the spraying will be rescheduled for Wednesday, Aug. 29. The treatments will be administered by truck-mounted equipment to spray open spaces in residential and recreational areas. The equipment dispenses Biomist 3+15 at a rate of .75 ounces per acre.
These products are designed to provide quick, effective control of adult mosquito populations. The application materials have a very low toxicity profile to mammals and are safe for the environment.
Certain mosquito species carry the West Nile virus, which can cause humans to contract West Nile encephalitis, an infection that can result in an inflammation of the brain. According to the Centers for Disease Control and Prevention, all residents in areas where virus activity has been identified are at risk of contracting West Nile encephalitis.
Mosquito samples in 47 counties have been identified with the West Nile virus so far this year. Human cases have been confirmed in Bucks, Centre, Delaware, Franklin, Lancaster, Lebanon, Lehigh and Philadelphia counties.
Individuals can take a number of precautionary measures around their homes to help eliminate mosquito-breeding areas, including:

Additionally, these simple precautions can prevent mosquito bites, particularly for people who are most at risk:
