A couple weeks ago I got stung by a little flying "thing" while working in the flower beds. No big deal. Three days ago I was removing some weeds on the garden steps and got swarmed by the same little "thing" only this time there were substantially more of them. Apparently I disturbed their nest which I didn't know was there. One sting on the arm, two on the eyelid. Sprayed the nest with some ant & roach stuff I had laying around and figured that was the end of it. This morning one of the dogs followed me down the stairs and disturbed the nest. Out they came and bit the poor little guy. I didn't know he could run that fast! Sprayed the nest again with the ant & roach stuff being that's all I had. Went back a bit later and picked up one of the dead ones to examine. We concluded it was a sweat bee. First time in six years here we've had them on the property. What can I pick up at Home Depot to kill off the nest? I don't want to trap them. I want them gone, permanently if possible.
