Hope they survive.
Last year I received a call after they sprayed the swarm. I found the queen and a small cluster of bees with her. They did survive.
I have a removal scheduled for this Sunday if it does not rain. Sprayed once last year, didn't die, so they sprayed again a few days ago. Didn't die.
Finally decided to call a beekeeper to remove them. ARGH!!!!
Keep us updated and also if the queen is really in there. :)
