Mosquito control treatment scheduled for Tredyffrin and Easttown Townships
to prevent West Nile Virus
West Chester, PA – The Chester County Health Department will conduct a mosquito control treatment spray in portions of Tredyffrin and Easttown Townships (see maps below). The treatment is scheduled for Monday, July 30th from 8:00 pm to 11:30 pm. The rain date for this event is Tuesday, July 31th from 8:00 pm to 11:30 pm.
The Chester County Health Department conducts mosquito control treatment in areas with high levels of mosquito activity and where multiple mosquito samples have tested positive for West Nile Virus (WNV). After exhausting all other available mosquito control strategies, spraying is conducted to reduce residents’ risk of WNV infection. Anyone living in an area where mosquitoes are infected with WNV is at risk, but the risk of infection is highest for people who work outside or participate in outdoor activities. Less than 1% of people infected will develop serious illness. While serious illness can occur in people of any age, people over 60 years of age, people who have received organ transplants, and people with certain medical conditions such as cancer, diabetes, hypertension, and kidney disease are at the greatest risk for serious illness.
