I moved my hives from my covered patio where I kept them for the winter to their usual summer spot on the other side of the yard (about 50 ft. away). All the forage bees are returning this morning loaded with pollen, but they are all swarming around the patio. I lit a small fire hoping the smoke would keep them from landing there, but they are just hovering around. What can I do to direct them to the new hive location? Thanks
