My friend is having more success than I. Scouts are sniffing around some old equipment donated to him, and a box he placed on his old homestead. I will check mine after this storm passes. Bees seem to swarm on a sunny day after a rainy day.

The swarm box in the picture above holds 6 deep frames in the top, and is 2xs taller than a standard deep hive box. You can find the plans on horizontalhives.com.
However, if I make more, I will probably just make standard deeps for my swarm traps, with a solid bottom board and a migratory top.
