I am investigating a mysterious case of bees in my bathroom. Every time I go in, one is buzzing around. I noticed they were gathered at the window. I search for cracks on the walls nearby, but no source was found. The screen is not torn, nor do I see them flying around in the window when closed.
Yesterday I went in, and crunched a bee under my boot. I then investigated the window, and found 4 bees. I was lucky enough to see one of them slip out of a small spot in between the window panels, so I have sealed it temporarily. I am now led to believe they have a nest in the wall...
