How do you commercial guys rob your bees in the fall and keep the bees from going on a robbing frenzy and getting into the hives? I only have about 15 hives on a trailer and do a trailer at a time, but the bees go nuts in the fall. I am using the fume boards and then move the supers to the truck after they have cleared out. I then cover the supers with a hive cover until I bring the next one on.
Any advice or tips would be greatly appreciated.
