The only bug I dislike more than the yellow fly (deer fly for folks Up North) is the chigger. I can avoid chiggers. These swarming yellow monsters follow me around all day and fly after me when I drive away.. An old fashioned solution to this is to offer them an alternative to eating me. They seem to like black, and/or STP oil treatment. It makes me very happy to see their dead carcasses stuck to the trap. When it looses its stickiness or is completely covered in bugs I wipe it off with newspaper and listen to them sizzle and pop in the fire.
