A friend left a glass bowl outside, and a wasp nest happened to be nearby

With fire and acid

I'm guessing they sprayed it and made sure it wasn't active.

Yes. Yes it does. Wasps go after and kill bees. Screw wasps.
Of course, you can hold them all in your hands and walk them to the nearest park.
When you get out of the hospital, let us know how that worked out.
