How to Choose Hiking Insect Repellent
Tick prevention is the primary reason to use repellent in the mid-Atlantic. Lyme disease is endemic in Virginia, Maryland, Pennsylvania, and New Jersey. The most effective strategy: Permethrin on clothing (kills ticks on contact, lasts 6 washes) plus Picaridin 20% on skin (8-12 hours protection).
Picaridin vs DEET
Both are CDC-recommended and equally effective. Picaridin does not damage synthetic fabrics or plastics (DEET does), smells better, and is less greasy. For equivalent protection with fewer downsides: 20% Picaridin.
