I have been using permethrin this summer qith awesome results. First used it for mosquito protection but it has worked for everything (including deer flies) so far. Make sure you read the directions as you use it on clothes not skin.

Permethrin is used on humans to kill scappies. If you're apprehensive, spray it on your clothes, and let it dry. Stays for up to 75 washings. Its also used for flea and tick control for dogs. Careful though - its deadly to cats.
