We have done quite a few cut outs and swarm captures but have never tried to get bees out of a structure with out cutting into the structure.
One of my friends recently discovered bees going in and out of a hole that leads into his ceiling. There is apparently no access to this void and he wants to avoid damaging the ceilling (wall board). I am concerned that even if we sucessfully trap out the colony that the abandoned comb with honey and brood will become a magnet for roaches. His wife is from somewhere up north and she runs screaming if she sees one roach or ant (here in florida we just throw a saddle on them and ride them to the neighbors) Any one have experience with this?
