Yellow jackets on the other hand are complete assholes. We had a nest of them in the yard once and they would go way out of their way to sting people, just for the hell of it.

This was my experience too. I had thought that bees had moved into a bush in my yard. I was happy to have bees there. A week later I was mowing the grass and felt several stabs of pain on my back and wrist. I turn around and see the air is filled with them. I had swatted one in my escape and had a corpse to inspect later and found it was a Yellow jacket wasp. From a distance I could see they were entering and exiting a hole near the bottom of the bush. A quick internet search later I knew that they were nearly dormant at night, and that they need a special oil they produce on the outside of their body to breath. Dawn dish soap apparently strips that away and they die, and its not toxic to the ground or environment.

I put half a bottle of Dawn squirted into their hole at the bottom of the bush at night. I never saw another Yellowjack wasp.
