Well we got a bit of a rush yesterday while pulling honey. Did lots of things wrong like having too many hives open and brushing bees off and sorting frames.The robbing started and in a few minutes the air was full of bees and 16 boxes of bees had wars going on their doorsteps. Lesson learned to have every hive with a good functional entrance reducer / blocker. We had to scramble to get them locked down and a bunch of wet blankets helped. Beginners read about it but dont realize how wild it gets and how quickly it spreads to other hives you are not even working on. Lots of dead bees in a hurry. Amazing how quickly comb gets tore to pieces. Anyhow we got away with it and the supers off and extracted. Lots of things to learn the first year.
