I came home from a few days away to find bees interested in the swarm trap I had sitting on my front porch railing. There has been a lot of activity in and around the swarm trap for the last two days. There are usually a dozen or so bees around the entrance and bees coming and going constantly all through the day. The weather has been sunny and warm.

How long (on average) do you find that bouts of interest last? How long does it usually take colony to make a move and decide, before you either see a swarm or the end of activity when they choose some other location?
