Warning. Ticks are out.
When I have to go in the woods more, for say turkey hunting, I use the Permethrin clothing soak. I swear by that, had a real good test of it a few years ago. I hunted with a buddy for half a day. When we got back to the truck I was tick-free. He picked off over 20 from his clothes, no lie. Maybe even 30. We sat on the same log, right next to each other. Little weird doing the clothing soak though since you have to wear gloves and not get it on your skin, but once its dry its fine. Lymes or chemicals, pick your poison lol.
I use this one: http://www.shop.biteandstings.com/product.sc?productId=106
