I'm covered everyday head to toe in permethrin. Hope they don't find out later that its toxic/carcinogenic. I use the commercial permethrin from tractor supply. Two things to remember: 1- If you are putting it out on deer hunting gear, give it several days to air out, outside in a breeze. the petroleum carrier will pretty much dissipate. 2- don't stress to much about getting the spray concentration exactly right. Mixing into a spray with water is to just give you more uniform coverage. A couple of coats of spray to the point of the clothes being damp is about right. hen let the breeze dry the garments out.
