I thought my bees were done for the season, so I collected all the filled tubes from the houses and put them in a mesh bag. This is to prevent parasitic wasps and other pest from infiltrating the tubes.
I had no sooner sealed up the back when three of my gals came back to the bee house. They were confused since the unfilled tubes were not arranged the same way (since many filled tubes were missing, taking up less space) and buzzed around the openings, looking for their tube. I felt bad for them, but I’m confident they will figure it out or start a new tube.
I’d rather have a couple of confused bees than those nasty wasps in the tubes!
