Enough alcohol will kill anything, although I doubt they'll go down with a spray like fruit flies do just because they're so much larger. Thymol won't work on wasps, they use it in bee colonies to kill mites. I'd get proper poison to kill them. Some roach sprays are "ant, roach, and wasp."

Although personally I've found if you leave them alone they leave you alone although of course wasps and hornets have far shorter tempers than bees.

I used to do community service at a park, which was such an awesome job. I'd volunteer if I could but they already have boatloads of free prison and probation labor, they don't want anyone. I guess that's the good kind of slave prison labor. It benefits all parties and the community profits (ideally, I'm sure someone has a finger in the pie). Just a tangential thought.

Anyways, people would toss their drinks into the trash cans. It sloshes around the garbage and ferments in the warm heat of the day into something I think of as Mystery Fluid. You do not want mystery fluid on you. It's more foul than Ticketmaster.

This attracts bees. Lots of bees. So many bees. The air around the barrels of mystery juice was thick with them. I was the one who got to go get the garbage out of those cans when they were swarmed with bees. If you calmly walk through them you can tie the bag right up and they're pretty okay with it.

In retrospect that was kind of a long and wandering tale that wasn't that interesting, but I already wrote it so, it stands.
