I’ve always relied on a kind of weird method. It’s not the easiest to get set up, but once it’s in place you can pretty much forget about it.
We find the biggest red wasp nest we can (they are the aggressive @*%holes in these parts), usually in the woods, and kill them all with spray. Then take the nest (it has to be on the larger size for the species), clean it out somewhat (too much larvae weighs it down) and then give it a few coats of clear acrylic spray. Hairspray will work in a pinch. This helps it last longer in weather and when being handled. Then hang/attach it in a prominent location when you’re camping/recreating, usually 6 to 10 feet off the ground. The idea is the wasps think that there is a much larger swarm here and they naturally avoid the area altogether out of self-preservation.
If you have had the pleasure of living with/ being around the southern red wasp, you know why great lengths can potentially be worth going to. Even the yellow jackets and other annoyers around here pay heed to the red wasp.
We’ve had good results with this method over the years, although sometimes it can obviously be more difficult to procure a nest. One of my buddies who is a surveyor comes across the really big ones pretty often.
YMMV, especially depending on different species behavioral patterns.
