Permethrin works on clothes, if you want to have a bit of extra protection for where your poisoned clothes don't protect you, neck hair etc., in bad situations something on the skin may be needed. My meat provider, organic rancher, uses oregano spray for himself and his livestock. He swears by it, he has native prairie pastures and legume pastures that are always rather high and full of ticks. He says the ticks are there and yet they rarely get any ticks on themselves. The way I understand it, it is basically oregano tea. I am going to try it for next spring turkey hunting.
