When I move mine I put a small cut off tree branch or tall weed that I break off, in front of the entrance at night and in the morning when they come out, they reorientate (?) to the hive and its like a reset button on the ole internal gps of the bees. We have a bad black bear problem so I always have to keep bees in an electric fence protected area, my apiary isnt that big so relo to my bees is a matter of feet, not miles.
