Public and commercial spray operators are required to give advance notice of spraying to registered individuals, who can then take defensive measures like closing windows and turning off outdoor air feeds, or else try to leave town at the time of the spraying.
To be precise, “pesticide businesses are required to make notifications to you 12 to 72 hours in advance of any pesticide application to an attached structure or an outdoor above ground application that they may make within 500 feet of any location that you have listed in the Registry.”
Unfortunately, we have learned that certain unscrupulous or unqualified spray companies have failed to give the required notification or even sprayed the wrong property. If anything like this happens to you, please contact us so that we can try to help.
In addition, the Chester County Health Department has, at times, granted registered hypersensitive individuals an exclusion zone around their residence to spare them from chemical exposure. However, that exclusion zone may not be large enough to have an effect.
If you feel you qualify, to register you can download the form here: Pesticide Hypersensitivity Application Form(2020). Then print and fill it out, request a physician’s signed approval, and submit it. It is really up to the physician; the state and county have no input. All of us are potentially affected by toxic chemicals, some of us more than others. If you have any doubts, please talk to your doctor.
Further background info at Penn State Extension includes:
“The Pennsylvania Department of Agriculture (PDA) maintains a registry of individuals hypersensitive to pesticides. It is a listing of locations for people who have been verified by a physician to be excessively or abnormally sensitive to pesticides. These hypersensitive individuals may request to have listings of their home, place of employment, school (if a student), and vacation home placed in the Registry. A person will not be considered included in the Registry unless their name appears in the current published Registry.”
Note that you can register not just your home address but up to 4 locations that you yourself may frequent, such as work place, school, or second home.
If you have children in school, be aware that a separate state law grants a higher degree of notification to public schools than to private or religious schools or day cares. The PA School Code requires notification of families and employees of public schools (but not all schools) before spraying occurs. For more on that lack of equity, see here.
