Sounds crazy...but it WORKS!!!
Played golf the other day with an older Gentleman that joined our threesome. The three of us are going nuts after a while with all the gnats buzzing in our ears, eyes, and noses...but not the old guy. He shared his secret with us. He uses one of those Bounce fabric softner sheets you throw in the dryer. He takes the sheet and quickly wipes his face, ears & neck with it, then throws it in his hat! The next day I tried it and it worked GREAT! I could feel the gnats buzzing my arms, so I took the sheet out of my hat, wiped my LEFT arm only and tossed it back under my hat. Guess what? They buzzed my right arm but never touched my left arm the rest of the day!
Not only was I "bug-free"...I smelled pretty fresh too!
