Probably carpenter bees which look a bit like bumblebees. All the bumblebees I’ve ever seen had nests in the ground. All bees are good and should be left alone unless they get inside your home. Wasps, hornets, and yellowjackets are nothing but evil. LOL.
My mother raised me to have a fear of bees. I wish I didn’t because summer’s can be unpleasant when hanging around outdoors. I get a little paranoid lol. Had a wasp fly into the car while driving, I was blocks away from home. I tried to make it there without freaking out and blew the stop sign at end of my block, traffic all clear though, Go into my driveway and cop pulls in behind lol. Figures. Anyways I smiled, assured that he’d let me off once I showed him what had possessed me to do such a thing, as we looked around for the little bugger he wouldn’t show himself, or he had flown back out one of the rear windows.
