I have captured four swarms. Two were successfully housed, one moved on, and one died. In the one that died, I think the queen was killed. When a friend was sawing the brance off of the tree, a pile of lawn waste she was standing on collapsed and the branch broke. I got about 20 stings, cuz I was only wearing a sweatshirt and shorts.
The two big swarms I caught were successfully housed and went on to produce honey. The one that flew away? Who knows. I never got another call about it.
