Funny. We called them “Meat Bees” as well here in the South Bay...
They aren’t as aggressive as people make that type to Bee...
Wasps and hornets are at times carnivorous. Fall is coming quickly and they know it. Baiting a yellowjacket trap with some apple cider vinegar, a banana peel, and a piece of rotting, stinking meat will have them flying to their capture and ultimate death in very short order.
There was a lot of them in the desert out at my place Labor Day weekend. I just hung a strip of bacon over a branch about 30 feet from my camp/cook spot. I was happy, meat bees were happy, the world was at peace... :-)
