So far, it seems to work just fine.
I took an old wood milk crate (hard to find now, but you can build one along same size/shape pretty easily and cheap too) Knocked out the insert centers of each side and stapled in screening over each side and same for lid..
now, just put the swarm in the crate as one would a cardboard box, etc.
It has been very stable and transports well. Bees get plenty of air yet not able to get out.
toying with an idea to drill a hole in the bottom edge of one side and have a lockable plate or door of some kind.
Thinking maybe one could set the crate directly in front of new hive entrance and let the bees walk out of the box, right into the hive.
What do you think?
