Do not enter!
Bees on walls and ceiling!
Help is on its way.
!!! DANGER !!!
I peeked in, expecting to see a writhing, angry mass of bees, but was disappointed. Fear Factor it was not. Two or three lonely, quiet bees on the walls, another high up on the ceiling. So nothing to worry about.
I went downstairs nonetheless. Shifty bees, probably trying to lure me into the corner before they strike.
