Over the last couple of months I discovered horse flies. Those monsters apparently thought I tasted great, they would bite huge chunks out of my back, thru my shirt, while ignoring everyone around me. I knocked a bunch of them out of the sky with my Tilley, then turned them into grease spots on the ground with my boots. So I guess this could work. As long as you are ready and willing to stomp the badguy into the dirt after you slap him/her with your hat...
