Carpenter Bees in the Basement?

Flag

I have recently seen 2 buzzing carpenter bees in my finished basement near the window. I killed them and started finding around 12 dead bees of all sizes. What would be killing them? I haven't treated anything because I just figured out what they were. Also I haven't found any holes yet, that really seems odd.

I do have some baby cribs unassembled in the basement with the pre-drilled holes maybe they are living in there.

I have them on my wooden deck and wooden front porch. After they get done boring holes in the wood, they die.

Hi Becky,
Did you check the crib? I suggest spraying some WD40 in the predrilled crib wood holes and see if anything comes out of them. . .I discovered a large group of carpenter bees had used some METAL tubing with predrilled holes that was a structural support beam under my teak dining outdoor table.

They didn't touch the teak wood, they simply went inside all the predrilled holes in the metal pipes! I sprayed every hole with WD40 in quick succession and at least 15 bees fell out and died, some with their butts hanging out of the holes. Good luck!
