Tried the (relatively) new picaridin bug spray (gel, actually, in my case, but there's spray and lotion as well) this season, and I am never ever going back to DEET.

No smell, no grease, no damage to synthetic fabrics, and works just as well as 90%+ DEET formulations if not better. Tested in deep woods crawling with ticks and inundated with mosquitoes. Major success.

Just thought I'd share as a bonus for my fellow federated campers who haven't heard of this stuff yet. 5/5 stars, A+++++ would slather again!
