Could a hive get robbed to death? I noticed robbing in all 3 of my hives last week. I shut the covers to leave only the front entrance and no back opening. This week, the robbing continues, so I shoved in branches as make-do entrance reducers. Two of the hives are already weak (swarmed, queenless?), but the third is strong in spite of this.
I am STILL waiting for enough time and a warm, calm day to get into those hives 1 more time before winter. I wonder what awaits me and if I will need to do emergency combines for winter.
