Ed Goldstien is a friend of mine who enjoys his bees. Every now and then he takes bees out of someones' wall. This year he tried an experiment and it seems to have worked well, so far.
What Ed did was he made a box which he could attatch to the wall of a house, so the bees would have to go thru that box to get out and to get back in. This box holds 4 frames each on two levels. Basically like a two story four frame hive, or nuc box.
After having been on the wall for about two months, Ed noticed lots of bees bearding on the outside of his "hive". So he took it home, figuring he could at least get most of the bees and maybe the queen too.
When he went thru the frames, after getting the hive home, he found a number of frames of brood and the queen. She must have moved out of the wall and into Eds' hive.
I believe he will be taking another hive back to rob honey out of the wall. The owner didn't want the wall opened.
I wish I had pictures. I have encouraged Ed to write something for the Bee Mags, w/ pictures.
