Birmingham and Thornbury get 48-hour warning

[DSM note: This is not what we want to happen. This large residential area on both sides of route 202 in 2 townships contains many dwellings and several bodies of water and streams. Anyone in the area, please try to observe and let us know:

• Are adequate warning posted well in advance so residents and visitors will know to stay out of the way of the spray and take protective measures?
• Did you observe people who were not aware of the recommended precautions?
• Is there a vehicle with a loud speaker in front of the spray truck warning people to stay indoors or leave the vicinity?
• Does the truck spray more than once in any street or on any area?
• Is the spray shut off as the truck approaches a stream or body of water and if so, how many feet away?
• After spraying, what difference do you notice in the number of mosquitoes and other insects such as honey bees and dragonflies?
• Did you notice any effect, either immediate or after a few days, on children, cats, frogs, birds, or bats?
• How long does it take for the adult mosquito population to get back to about what it was before?]

Mosquito control treatment scheduled for Birmingham and Thornbury Townships

News release from Chester County Health Department, 8/8/17, 4:30 p.m.

The Chester County Health Department will conduct a mosquito control treatment spray in portions of Birmingham and Thornbury Townships (map of treatment area). The treatment is scheduled for Thursday, August 10th from 7:45 pm to 11:00 pm. The rain date for this event is Tuesday, August 15th from 7:45 pm to 11:00 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.

The Chester County Health Department uses a truck-mounted sprayer to apply 1.5 ounces of U.S. Environmental Protection Agency-approved product (Permanone) per acre of land. The mosquito control spray becomes inactive in just a few hours or with sunshine. Sprays are conducted after sunset, when mosquitoes are most active and bees have returned to their hives. Sprayers are turned off near bodies of water and apiaries to protect aquatic life and bees. The Chester County Health Department also notifies registered beekeepers and residents who are listed as hypersensitive in a designated spray area prior to conducting a spray. People who are concerned about exposure to mosquito control products can reduce their potential for exposure by staying indoors with children and pets when their neighborhood is being sprayed. If you would like to take extra precautions after the spray is completed, you can rinse off outdoor furniture or playground equipment before use.

Although spraying helps to reduce mosquito populations, the Chester County Health Department encourages residents to “Make You and Your Home a Bite-Free Zone” to prevent WNV and other mosquito-borne diseases. Because mosquito-borne diseases are spread through the bite of an infected mosquito, residents can reduce their risk by using insect repellent and other personal protection and getting rid of standing water on their property….

  1. Thank you for the warning. Protect children and pets. Stay inside during the spraying and wipe off outdoor picnic tables and play equipment before using after the spraying event. If you have questions or concerns, contact the Chester County Health Department.
