My bees are relentless once robbing begins, they will not stop. I tried many techniques which all failed, even moving and hiding the robbed hive.
The only way I found to stop robbing is this: In the evening, leave the robbed hive body in same location, remove all bees and frames to new hive body, relocate the new hive, then replace the frames with empty frames into the original robbed hive. When the robbers return they find an empty hive, empty frames, figure the bees absconded and give up. This has worked for me every time.
