Bees need to fly. I have never thought of caging them to keep them. Using excluders as includers, giving a frame of unsealed brood, have almost always worked for me. I guess I have been lucky and most always got the queen. I have never gone for tough removals or high wire acts in captures. (hey!! look at me working without a net!!) I told the Fire Department guy and the sherrif, I'll pick up swarms if they are reachable. I'm not handy enough to tear into a house, and too old/large, to climb a tree. Maybe that's part of my luck.
