In my experience, just vacuuming up yellowjackets in a shop vac kills them. No soapy water needed.

I don't understand how that kills them. Blunt trauma?

Seems like you'd just have a huge pile of mostly-alive wasps in your shop-vac.

Most insects are very prone to dying of dehydration if their exoskeleton is pierced - it's how diatomaceous earth works. My best guess with how vacuums kill insects is small nicks to the exoskeleton from flying debris causing eventual death. I've never vacuumed up an insect or spider and seen it come out alive.
