Best of luck!
If you can be prepared enough to put out a box similar to what you want them to end up in, that's a help.
In school we use an old nuc box as a bait hive.
Our national hives are foundationless in the brood boxes, so the nuc just had empty national frames.
Went in to school this morning to find it occupied.
The frames will then be transferred straight from the nuc into the empty national we have waiting.
At home we use Warre hives.
I put a spare box with top bars (no comb) on the roof of the shed a couple of weeks ago and that got filled too.
I was then able to transfer the whole box of bees to a new stand with floor, quilt and roof.
Both bait hives had a swarm wipe in.
Elevating the box does seem to help.
