I have lived in the woods with the bear flies, deer flies, gnats & house flies that bite. Summers in South Ga. are usually damp and muggy. I said that to say this ....Permethrin (may not be spelled correctly 38 percent and put in a hose end sprayer or hand sprayer (hand sprayer 1 tablespoon to qt. water) and spray the area you are going to be in for a while and they usually will stay away. Got this from a hog farmer years ago and it works. The color of clothing matters to but I forgot the colors not to wear. yellows and red I think.
