I have motivated them a bit when changing entrances around with cloake board etc., by smearing something repulsive to them around the old entrance you have blocked. They are homing on the scent of their original entrance. I have used Vics Vapor Rub, and an arthritis rub that is strong of methyl salicilate (wintergreen). That makes them give up on the old location quite quickly. I am sure the bees hate me at times; surprised I dont get more stings than I do!
