Sometimes the bees take the queen and leave when things get bad in the hive. That is what happened with this hive. We had to smoke the hive so we could see the comb, shortly after we started removing the comb my wife said she saw what looked like a swarm forming on the roof across the alley. We took the comb out and noticed that there weren’t very many bees in the area. We put the hive near the “swarm” because we were sure they were from this hive. We thought they would go into the hive since this was now home. We went to lunch, when we came back they were still on the roof. My wife suggested the queen may be in that group on the roof. The person who came to help us went on the roof and scooped them into the box. As soon as she scooped them into the box they all trooped right in. We waited a bit and brought the box down. The woman who was with us was very new at this and said she never thought in a million years as a bee keeper she would be climbing on a roof to catch bees.
