Methyl Parathion Registration Cancelled - Federal Register: October 27, 1999. Includes uses of Penncap-M (microencapsulated methyl parathion).
Methyl Parathion Summary - EPA Office of Pesticides.
Illegal Indoor Use of Methyl Parathion - The Environmental Protection Agency believes that individuals may be using methyl parathion illegally indoors as a treatment for cockroaches because some have found it to be effective against these pests; it is a relatively inexpensive pesticide; and it persists (lasts) for such a long period of time when used indoors that frequent retreatments may not be necessary. However, this toxic chemical's persistence indoors is one of the key reasons that individuals may experience adverse health effects. When used according to its registration -- only in open fields (outdoors) -- methyl parathion breaks down and dissipates more rapidly. EPA, OPP.
