Hi Eva, just use a frame after you shake the bees off. It’s best to virtually put the frame right up to the bees like I showed. Then after 30 minutes or so, gently move that frame into the brood box with whatever bees are attached to it. Because the queens normally gravitate to the brood, it’s most likely the queen will also be on there. When that happens, the rest of the bees will follow.
It’s unfortunate we didn’t get to video the bees leaving the top of the clothesline, it happened while we were talking to the home owners.
Just a side note, I don’t really shake shakable swarms. If I can sit a brood box (with the lid off) directly under the swarm, just touching it, as long as I have a frame containing open brood in the box, the bees will move down into it. After most of the bees are in, I’ll put the lid on, then put the box on the ground on top of another box. Then sit back & watch the bees at the entrance fanning their scent out.
PS, a couple of drops of lemongrass oil also helps.
