S. Sumner,
I know about them European Hornets! Hadn't been stung (knocking on wood) but came close enough. My parents live in Randolph Co., AL, it borders the GA line. They got them nasty critters there.
HOWEVER. I DO NOT recommend shooting them with rat shot! Been there done that. Was pretty successful, as they are quite large. One at a time was coming to a tree oozing sap. Another would come up and chase the one on the tree away. This was a regular thing. Well, Ol 35 Rem gets out the 22 w/rat shot and start plugging the little boogers, one at a time. Shot about 3 or 4. Well, Number Five flies overhead about 15 feet, a different flight pattern than the rest. The shooting had stopped waiting on another. Number Five circles around, comes back over the "Scene of the Crime" about 5 feet and gettin' it! I turn to high tail it as he circled around again. As I was turning he hit the end of the gun barrel! Guess he figured that was the culprit. Well, I found another gear at that point.
Not real interested the "flesh rotting" thing.
It was a real experience.
Those are really nasty bugs. They will come out at night, too. Don't leave the porch light on. They come looking for moths and other bugs to eat. We would spray Wasp and Hornet killer around the sliding glass door frame and light and turn on the light. They come up and get in the spray. It makes em real mad and they writhe around and try to sting you through the glass door! The venom runs down the glass...It's very interesting. I definately wouldn't want to get into a nest of 'em. I don't think a fella could survive it.
