I was hunting in the breaks this past week and the gnats were making a meal of me. Thermacell did not work, worked great on the skeeters, but not the gnats. I had 3 other types of deet based products and none of these worked. Had a facenet and that kept them at bay, but I ended up with bites all around my eyes. What do you guys use that actually works. These little buggers just about drove me mad!
