They potentially could go into survival mode and build comb, particularly with a few hundred bees, but I think there is a good chance there is a queen with them.
The last several hives I've removed lately had multiple queens. Its best if you can finish your cut outs late, so you get most all the bees.
At least with this new call, you may not have a lot of comb to remove if you can get there soon enough.

I hope it has a queen. It would be nice to have a nuc.
I'm going back tomorrow to remove again. I've been contacted by a grad student journalist major doing a video on beekeeping, she wants to come video a cutout. I kind of feel like I'm cheating to bring her to a half done deal. We'll see.
Oh, JP, I forgot to ask. How do you use your beevac? Do you vac off all the bees you can then start cutting comb? Or do you just vac off bees from the comb you are about to cut and not worry about the rest?
