This is "right before I brushed them" and right after they make a break out from the trap box.
I did get them on a second attempt but they swarmed out as soon as the sun came up the next day.
Did you try the drum?
Bees in winter - new phenomenon, but I've got them... So far so good.
If you put a frame of brood in with a swarm they wont leave. Before i knew this i lost about half my swarms putting them on foundation alone.
