Help with bee, wasp or MONSTER Hornet!!

We've had Cicada killers around here for as long as I can remember. Never knew what they were for yrs. and never once had one try to sting me. The first time I saw one I was like you cause bee/wasp stings sometimes produce an alergic reaction on me and those things sure are intimidating to look at.

BTW: if you don't have anything handy to fend off a bee/wasp brake or carb cleaner works pretty good. I even killed a snake (a 2-3' cottonmouth) with a can of brake cleaner.
