I found and moved a bombus impatiens nest here in Michigan last summer. Impatiens seem to be the most populous bumble bee in my area. My nest was under some garden debris from the previous fall. Bumble bee nests are much smaller than honey bees and hence I used a small box to put my bumbles into. My box was about 6”w x 8”l x 4”t.
My guess is, like honeybees, it is probably better to put them in a box size that they can protect. Wax moths seem to like their nests too. :( My colony was of modest size and fit my box fine.
I just suited up, got a shovel under the nest and moved the whole thing into the box. They were REALLY buzzing loud as I moved them, but they didn’t try to attack me, and the move went smoothly. I moved the box with the bumbles about 150’ to a new location and they did fine. They seemed to re-orientate ok with the 150’ move. Like honeybees, they don't seem to be able to see Red light, so moving them, or observing them under Red light is also an option.
I'm a little surprised your honeybees didn't find this run down home to live in. ;)
