We hightailed it out to his house which took half an hour. He had watched a swarm land in his neighbor's tree. He did the legwork ahead of time, letting the neighbor know there was a swarm there and that he knew a bee-keeper who would be happy to catch the swarm and get them out of his yard for him.
Anyways, we get there and bring all our equipment out. There is a brief discussion as to how best to approach getting the swarm out of the top of the tree. Suddenly, there is a huge buzz and the swarm lifts off and starts heading across the street.
There is much swearing as all three of us try and follow the swarm. But instead of landing somewhere or the entire swarm heading in a purposeful direction, the bees seem very confused. Most of them head back to the tree where they had just been sitting.
We decide that we lost it and head back to collect our gear when I noticed there was a suspicious pile of bees at the base of the tree. My husband goes closer and there is the queen! There is a mad scramble as he runs to where we had all our equipment and up-ends his bucket of gear trying to find his queen-catcher or a queen cage.
There is success as he finds a queen cage. He runs back to the lump on the ground, picks up the queen, puts her in a cage, and then inserts the queen cage into a pre-arranged super. He then sets the box down near another clump of bees.
For the next hour and a half, the rest of the swarm gradually leaves the tree and lands where we found the queen on the ground originally. They then march over to the box.
