any deet is good deet. i took an old ball cap i had and just saturated it with the stuff, also an old t shirt that i keep in a plastic bag all sealed up i can wrap around myself. these are just a few ideas that ive had. if you do use deet though, i use 95% deet make sure you shower as soon as possible and dont touch anything plastic, including your gps, i put mine in a plasic bag to help protect it. good luck with the bugs!
