I know many of you have switched from DEET to picaridin. I have used the 15% stuff with mixed results, but the 20% seems to work much better. It smells pretty good and won't melt your gear. I just noticed that my local ****'s Sporting goods has big spray bottles of Sawyer 20% Picaridin. Thought I would pass the info along, since the 20% stuff was tough to find last summer. I plan on picking up a bottle or two and hopefully will not have to pick off ticks this year. (note: This is for body and clothing, not really to treat hammocks. For that I stick to permethrin)
