Sawyer also makes Maxi Deet you usually can buy it at Wally World in the sporting goods area. I have also seen it at Academy, but as someone mentioned a few posts up, 100 percent Deet can reck your GPSrs screen cover, the screen cover to your FRS radio, as well as melt certain types of plastics. I have experienced this myself . But it does keep pretty much all the bugs away. My suggestion, if you use Deet in high concentrates do what I do, use those screen covers for PDAs on you gear. Not only does it protect the gears covers from Deet, but everyday wear and tear. All you do is buy a set of the PDA/Pocket PC covers and cut to fit on your GPSr or FRS radio.
On another note, recent studies with Skin So Soft show that the stuff is about as effective as sugar water. Personally it may not keep the bugs away, but it will keep me away, I cannot stand the smell of the stuff. Year backs I brought some kids camping. My brother brought a bottle of Skin So Soft for bugs. As night set in the bugs came out, and my brother slathered the kids with the SSS. My fosterson was 7 at the time, he did not like the oily crap all over him, and it was not keeping the bugs from biting him, infact many moths where sticking to his skin. So I took him down to the river to wash, he stood in the rivers water up to his waist, after about five minutes he started crying. When I asked what was wrong, with tears streaming down his oily little face, he sobbed out "It's not coming OFF!" Luckly I had some Dawn dish soap, he washed another two or three times with that before he had it all off.
