Any stinging insect like bees/wasps, etc.
I mean, it does hurt when you get stung of course, but I think I may carry it a bit too far.
I've only been stung once in my life. Right on the .. ass through my jeans when I was a teenager.
I felt a burning sensation on my butt, pulled something off, it was a yellow jacket I think. Then when I went to check, I had a large red mark on my ass that hurt for several days.
I believe that is the only time I've been stung.
They used to come in through cracks in the window sills when I lived in PA but I always got bug spray and killed them.
