Do a search on this website for "Permethrin." There was a thread about 3 or 4 years ago about ordering concentrated permethrin and then treating your own clothes. Much much cheaper. With the concentrate, I will make a big bucket of the stuff and dunk all of my clothes (except what I sleep in), wring out as much as possible, and let dry on the back fence. Additionally, I have put it in a spray bottle, set up my tent in the back yard, got inside of my tent, and sprayed out through the netting. This stops the little blood suckers from lining up on the screen and drooling at me when I'm on the trail. I treat everything because I don't use Deet. At night time I wear long sleeve shirts and pants, bug helmet, and put my hands in my pockets if conditions are really that bad. Or, I retreat to my tent and watch them land on the netting and immedialty take off.
