West Chester, PA – The Chester County Health Department will conduct a mosquito control treatment spray in portions of Phoenixville Borough and Schuylkill Township (see maps below).

Read the full release at the above site.

This planned spraying with the pesticide deltamethrin involves big chunks (see maps online) of densely populated neighborhoods. (Isn’t it odd how the press release text finds euphemisms so as not to use the term “pesticide,” which occurs only in the EPA-related statement at the very end?)

As mentioned in “Mosquito spraying and public information,” the public and their elected representatives can’t find the underlying data online because the usual sites have not been updated recently. “Just trust us”?

On the futility of this kind of spraying, see “Why don’t they just spray and kill all the mosquitoes?

If you are in one of the spray areas, please see “In case of spraying: Help us / Help yourself.” You should protect yourself and y our family, but also your observations can help us catalogue the conditions and effects of spraying.

Mosquito control treatment scheduled for Phoenixville Borough to prevent West Nile Virus

[DSM needs citizen help in observing Health Department procedures and the results of spraying (which in general we oppose). Anyone in this spray area, please try to let us know:

• The release says “After exhausting all other available mosquito control strategies…” Do you know of other such strategies to date, such as working with the municipal government to educate residents, larviciding suspect bodies of standing water, or alerting property owners whose properties may be violating the Health Department’s regulation against allowing mosquitoes to breed in standing water?
• Are adequate warnings 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 lead truck 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? Does it crisscross any area, thus delivering a double dose to some addresses?
• 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?

DSM needs you to help protect people and the environment and to let public officials know what you think.]

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 will use PA DEP equipment – a silver Ford Ranger affixed with the PA DEP logo and BU# BU2626 – to conduct the spray. A truck-mounted sprayer will apply 1.0 ounces of U.S. Environmental Protection Agency-approved product (Biomist 3+15) per acre of land. A white GMC truck affixed with the Chester County Health Department logo with BU# BU1901 will be the lead truck. 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….
