Andrew from Winsted, Minnesota writes,

If Permethrin SFR 36.8% is safe for carpets, why not clothing?

If Permethrin SFR (in a properly diluted effusion) is safe for use on carpets, why is it not safe on clothing? I walk barefoot on carpets. My children have crawled on carpets. From reading MSDSs and FDA pages on Permethrin, human contact is only hazardous prior to it drying (while a liquid or vapor). If applied to clothing that is allowed to dry fully before it is worn, where's the risk? Are your compound's inactive ingredients contact toxins, or are you simply trying to discourage a use that is not formally approved for your formulation?


Permethrin SFR 36.8% is not labeled for use on clothing and is not formulated for such a use. We recommend that you contact the manufacturer for additional safety information. They can be reached at 281-892-2500 (Control Solutions).
