I picked up the remnant of a large swarm that had been sprayed on last Friday, last Saturday. I had never dealt with a situation like that before, so I just had to go.
What started out as a beach ball sized swarm had been reduced to under-inflated volleyball size. I suspected they were queenless after watching them for a while after hiving most of them them. When it appeared they were not going to stay, I ran home and grabbed a frame of brood and eggs from one of my hives. Well, that was the ticket, I tossed a bunch of bees back in the box and within minutes, the march was on.
I was expecting to see some losses still manifesting, but to my surprise, nothing like that happened. I popped the lid on them Thursday, and they have at least 6 queen-cells made and they look as good as any other bees I have.
Pleasantly surprised...........Joel
