Look up the homemade water traps. You take a large plastic storage bin and fill it with soapy water. Then you put a piece of wood over the top of the bin and hang chunks of raw chicken from below. The wasps take a chunk of the meat, and then fall in the soapy water.

Then you go outside to check the trap, and as you’re standing there saying, “Wow, look at all the wasps!”, the bear who showed up for free snacks rips your face off. No thanks!
I do something like that for fruit flies. I put apple cider vinegar in a cup and add dish soap. Cover the top with plastic wrap and cut a hole in it. Fruit flies go in and never come out. Works like a champ!
