Or at least it was a swarm but they had found a home. In a barrel.
The bee scouts had found a medium/small sized barrel sitting outside on a deck. It was being used as a plant holder and it had a perfect cork sized hole in its side. Not only that, the barrel was 1" thick, giving great R factor and it was located under the soffit of the house, providing warm from the bricks and protection from the rain. Bees are so clever they never case to amaze me.
I picked up the barrel and when turning it upside down I could see about 4 or 5 medium pancake sized combs which the bees had created. I could guess the bees had probably been there for a few days to a week. I placed a bottom board and deep down next to the barrel and then tipping it upside down I shook the bees out. As usual, many bees went into the deep (it had frames) and many went into the air.
The homeowners stayed inside most of the time and took photos through the patio window. But they were brave enough to come out and look.
And it happened just like that. But I'm not one to leave any bees behind so I left the hive there until after dark. I returned and picked up the hive, and the pieces of comb that had broken off but they had honey in them so I took them too so I could give them back to the hive.
I set the hive up on a new platform at the Heeman's bee yard. On top of the hive I set another inner cover on top of the first one and set the pancake sized combs on that. The bees could travel into it to rob out the honey and wax if they desired. And they did--all the honey and the wax.
The hive did very well all summer and even though it was a late swarm (they said a July swarm "ain't worth a fly") they're worth a lot to me to replace losses. I gave them some frames of drawn combs with honey to give them a boost and also pollen patties.
The rest they took care of themselves.
