Permethrin vs Deet Stack

The most effective personal protection against tick attachment in field studies is the combination of permethrin-treated outer clothing and a 20 to 30 percent DEET (or 20 percent picaridin) repellent on exposed skin. Each works on a different surface and on a different stage of the tick's approach.
