I have done two cut-outs this year, but have not seen any swarms. I went out this morning to water the garden and noticed something kinda funny in the bee yard. I had built two 8 frame deep boxes and left one of them open. I always put some frames in them just to keep the frames out of the way. Frames have no foundation, just frames. There were probably 50-60 bees going in and out of the hive. Then I heard the swarm. They came over my bee yard from the north, kept going across the street and landed about 15' up in a tree. As soon as they landed, the bees that were checking out my hive followed them. I grabbed my new, untested swarm catching rig, the hive body they were checking out, now with frames and foundation and one frame of drawn comb and headed across the street. The rig worked great and they are now living in their new home in my yard, hope they stay!
