I say prob yellow jackets, those suckers are nasty when you pass by a garbage can.
I put 6 hives on a small trailer offset so I can get behind them to work on them. All have a ratchet strap on them to keep from moving or loosing anything like the tele cover. They are only about 24 inches off the ground with bottom ent. Great thing is I just have to cover the entry with screen and hook up to the trailer with the pick up to move them. I do smoke them a little, it works very well for 99.9% of the guards but that’s why they call them guards, and some are very good at their jobs...ouch.
Put a small branch in front of the entry when you get to the new location so they reorient.
