Please Help! These guys have gotten so aggressive I can't even set foot in my garden without being attacked. I really like the little guys since they look cool, and keep all the other garden nasties from munching on my veggies. Earlier this year I removed a couple of large nests from some wind chimes hanging in the tree in the middle of my garden. They seemed to disappear for a while before they took up refuge in another wind chime hanging on my porch right above my favorite chair. They weren't building a nest though. Since then I've spotted huge clusters of them huddling in any structure they can find, and although there's no nest to protect they are still just as aggressive as ever.

I just want to be able to work in my garden without having to kill them all. Is there some organic method I can use to keep them at bay while still allowing some of them into my garden?
