Permethrin is definitely the best thing I've found. I spray my work pants with a 12% solution. I've read that that mix will prevent ticks from being attracted, and is supposed to be good for 75 washings. I have my doubts about that so I spray them at least every other use.
Sitting on a tailgate taking a break, I've seen ticks walking up my pant legs and then fall off. I liberally coat my pants with this stuff and have been using it for going on for over 10 years now.
For the edge of yards and around the base of foundations (mostly to kill mosquitos since I do own swampland), I use a Stihl fogger with a Tengard SFR 36.8% Permethrin Insecticide mixed up with water.
