Once the package is as empty as it will get from shaking it, it’s time to button up the hive: I center the frames in the hive by pushing them in toward the center – gently, everything is done gently to avoid squashing bees! – try to get as many bees off the edges as possible, then put the inner cover on, using a side to side motion as I lower it in order to get any slow to move bees out of the way.
Then the top cover goes on and I set the empty package on the ground in front of the opening. The rest of the bees will make their way into the hive on their own, as they finish cleaning up the sugar syrup from the mesh of the package.
After they’re all in and secure, I leave them alone for a couple of hours, then go back to give them a quick check, mostly to ensure they haven’t absconded from their new home, and that the remainder of the bees have moved themselves into their respective hives. It doesn’t take long for the packages to be just empty boxes.
