OK folks -- now for the OFFICIAL word straight from Charles Feller of Coulston Products. I will note that Coulston is now a sister company of Sawyer (i.e. it is now Sawyer/Coulston) and that Chas Feller is one of the developers of Permethrin:
(Quote)
Coulston Products Incorporated is the manufacturer and EPA registrant
for the Sawyer Products' "Permethrin Tick Repellent" and Pro Products'
"Prevent-a-Mite" pressurized sprays. Prevent-a-Mite has directions
for use, Federal and State registrations and patented to control
(parasitic)
mites in reptile environments. Sawyer's Permethrin Tick
repellent has directions for use and Federal and State registrations for
application on human clothing. To sell and/or use Sawyer's Permethrin
Tick Repellent on reptiles is in violation for Federal law and US
Patent. To use Prevent-a-Mite on clothing is a violation of Federal
law. Whilst each product contains permethrin, an insecticide, they are
TWO DIFFERENT products with different use patterns and applications.
The difference is expressed in the EPA registration number 50404-6-58188
(Sawyer) versus 50404-7-73617 (Prevent-a-Mite).
We do not promote anyone to market, sell or use Sawyer Permethrin Tick
Repellent on reptiles because of violation of Federal and State laws,
violation of US Patent and potential harm that may come to a reptile for
mis-application of another product.
