Bee suits are like $40 last time I bought one. They’re worth their weight in gold! If you have lots of nests, it’s not a bad purchase!I've worked with boron hydride. Nasty stuff (high vapor pressure, decomposes, and absorption thru the skin if I remember correctly).
The shop vac without filter and with water in the can I know but it won't kill the queens. And I don't have a bee suit to sit next to it, and that'll be an issue for returning ones.
