In the last week, I have seen 2 wasps in the shack. I guess these climb in via my cable hole in the wall. I assume these are queens trying to find a place to nest. This is the first time I have seen them in the shack.
Years ago I remembered my dad being stung by a wasp. This would be in the 1960s. He was sunbathing in the garden when a wasp landed on his stomach. He sat up, trapping the wasp, that promptly stung him!
