Charlie used to play baseball every year. I have tried everything to keep the skeeters and gnats from eating me alive. One day i rushed home because i could not find my deet. Still not finding it i grabbed the dogs spray pump bottle of flea spray. sprayed some on my hands and rubbed in my hair and on my arms. Worked fantastic. Have used it every since. I have never had a reaction and i have very sensitive skin. I know it sounds crazy but when you are standing in a open field being eaten alive you will do anything short of setting yourself on fire to keep the bugs off. This stuff really works.
