I used to use permethrin. I went all goofy a few years back and swore off most of the bag and jug stuff. I still keep a little gly in the shed for emergencies, and I've got a bottle of that other bug stuff with the residual, but haven't used it. I've invested a lot of time in wide trails and good mowers to eliminate places for those ticks to stage. I also always wear rubber mid calf boots to keep them off as well. Then I just check every day I come in from the woods in front of the full length mirror. Once tick season starts, I don't go bombing through the waist high stuff. Raspberry canes are the worst. I've gone through 20 feet of those and come out the other side with 25 wood ticks on me.
Paper bags of lime under plastic are also a haven. I broke one open to see a few dozen come pouring out. Gross.
