i have an attic to do on Saturday. i'll trade you my attic for your outbuilding :-)
Here's one I did yesterday, I would trade for the attic one.
They were in a crawl space, between a sill and a joist and adjacent to a partition wall.
The sill had a gap 3' long between it and the subfloor. I could barely squeeze my hand into one end of the gap, but couldn't close my hand in the gap.
I used my knife to remove what I could, beequick did the rest. Set up nuc and will check this morning, may have even gotten the queen, but got two capped swarm cells, so maybe they'll make it.
Annette, these types are rare, stick with the ones that are in a wall space with an exterior you can remove, or panneling interior.
