This morning I opened up the old box to find a few scavenger bees - about 100 or so - milling around. The combs were empty but for pollen. There were two frames of honey....so they hadn't been completely robbed out.
I put together a box with the empty combs, the two frames of honey, two frames of honey from another hive, a new SBB, and a slatted rack and set this up about 10 inches from where the swarm was clustered on the fence. I then tried to move the swarm into this hive and I don't think I got the queen. They were on both sides of the fence and I didn't have access to my neighbor's yard.
So I left the box complete with swarm lure and went inside to get ready to go to work.
When it was time to leave for work, I looked and the swarm had taken flight. Swirling above the box they appeared to be increasingly landing on the entry to the hive box, so I felt some hope that they were moving in to the box I provided. I watched for a while. I went back inside when the swarm had settled, went out in the yard, and a majority of the bees had regathered on the fence. Either the queen didn't go in the box, or they were attracted to the pheromone.
I now have permission from my neighbor to go into her yard if the bees are still clustered at the end of the day. I'll let you know what happens.
