This is looking inside the void of the tree, the hollow part—I called it the "the top knot."
It was impossible to get them out without a vacuum. I don't like vacuums, so I got a Bright Idea: Put a tarp on the ground with a nuc box on top. I had cut out three frames of brood and two frames of honey from the tree, and I put those in the nuc box.
I picked up the "Top Knot" and slammed it down on the ground next to the nuc box. A big pile of bees fell out and started crawling into the box with the brood and honey frames.
Two hours later, they were ready to go.
