As regards the comments that hives can be moved about a yard within 24 hours, not true. A few years ago I had some observation hives that flew out a window and dive-bombed the nearby tennis court. No real problem, the bees were just getting their bearings, but I got complaints. So, I took the observation hives out of the east window on the second floor, moved them several miles away for 2 weeks, then brought them back to the original building and placed them in a 3rd story, west facing window. Well, by noon there were several hundred foragers outside the east window, trying to get in where the hives had been 2 weeks before. Jerry Bromenshenk [log in to unmask] The University of Montana
