Kirk has some feisty bees in a trap-out he's doing.

He says:
These bees keep chewing through the cardboard around the bee escape. I used tinfoil this time with caulk—that should help out.
I've taken bees out of this porch before. A swarm moved back in so I'm trapping them out. They will join the hive sitting you see in the picture. I added another box, thinking of the 10,000 bees that will be coming out of that porch soon.
