Annette, I held the box under them with my left hand, grabbed the side of the table, lifted up, then slammed the table down and 90% dropped in the box. Closed the box, taped it up, and let them enter through the flap. If you get the queen in, most will follow. If she flies out, you do it all again, but then I cage her and place her in the box. If you can leave the box at the site, they will usually all be in the box by night fall, and then you can just close the flap with tape. Ain't that one a beauty? I just freaked over it, it was such a unique swarm, they looked suspended in air.
