IF you get the bees enter this gizmo.... LOL
Well, you can set this up similar to swarm scion and get them inside that way.
I would not spend the money though - this is not a practical gizmo.
In the past we used very large canvas bags (pretty similar to a futon mattress cover in size).
The large size allowed such large bag to be just worn over entire branch (or a bush) with the bees on it.
You then snip a branch at the base and tie the canvas there - ta da - you have your swarm captured (wood and all - all inside a bag).
but with the entrance underneath so the rain cover didn't have to be cut.
I had three, two hung up and a spare one lying at about 45 degrees on a surface. The hanging traps had no interest as far as I ever saw, but the trap on a surface caught a small swarm (although it wasn't meant to).
So, from one season's experience, I haven't seen any evidence that bees like hanging cavities with entry underneath, unless there's a horizontal landing surface leading to the hole.
I decided the pain of getting them out cancelled out the cheapness and simplicity of the design.
