Permethrin
So I have seen a lot of people posting or asking questions about Permethrin. I also work at an outdoor retail store and have a lot of people coming in and asking questions. This is the report I have based my answers to those questions on. It is from 2011. I’m no scientist so some of the technical details are beyond me but it does have some good info in it.
