Rock house rescues has had a bunch of scout bees.

If ALL the wax isn’t scraped away and painted over, it will attract other bees. I checked the house, no new comb development or new residents, but there are definitely bees around scouting. Placing swarm traps or bee houses around house gives them another alternative to move into protecting the house. I may need to put a couple more out there, I think this one is already claimed.
