Hands down, permethrin is the best insect repellent out there. As potent as 100% DEET, Sawyer Products Premium Permethrin deters ticks, chiggers, mites, mosquitos, flies, and any other pest campers might encounter. Effective for up to 42 days, or six washings, it will keep your camping gear bug free all season. Best of all, it's odorless and colorless, so it will be perfect for fall deer hunting, too. Not coming home from the woods covered in bites is well worth the $10 for this repellent.
