I also highly recommend permethrin. Repel makes a product called Permanone which contains permethrin. I think Rural King still carries it, or you can get it online by Googling it. I repeat the warning: use it ONLY ON CLOTHES, not on skin. Used it for years and it solved my tick problems in Wisconsin, where the deer ticks and lyme disease are prevalent. I watched a tick crawl up my sleeve, thinking the permethrin was worthless. I waited a few more seconds and it just fell off! The product will last a few weeks, even after washing your clothes. Be sure to check yourself closely after your hunt. I have heard if you get the tick off within 24 hours, no problem, even if it was embedded.
