Get off the DEET train...
This is my bug spray of choice. I'm just not a fan of DEET, because as effective as it can be, I don't like all the warning labels, melted plastics, eroded synthetic clothing, and skin-burning sensations that can accompany it.
I used this in the Eastern Sierra last year, which was a banner year for mosquitoes (think thick black clouds), and had great results. I also like the small size of the spray bottle, it doesn't take up much room or weigh a lot in my pack.
If you are giving any thought to getting off of the DEET train, give this stuff a shot.
