Been through some areas with serious skeeter problems, Minnesota for 3 summers, a couple years in the Philippines, and done some back country stints in yellowstone where to be honest they will pick you up and pack you away. Best thing I have ever done is dress for them. Even in july backpacking and 90 degrees I wear long sleeves and a head net. Hands get bit a little but not bad. Deet for days in the summer will make you sick. Watched it too many times. Ill have to find the link to the plant but there is a purple flower that is sort of cone shaped that grows in the mtns that you crush up and rub on your skin will work better than any store bought repellent out there, what I use most of the time in the back country when I see it. Old time flyfisherman taught me that one.
