A few days ago I removed the last feeder after giving the colonies complementary sugar solution for winter feed before too low temperature arrives. Colonies surprised me being so calm I could speed up the work by bashing the feeder onto the hive in such a way that the bees sitting in the gate (by which they used to reach the sugar solution) fell into the open hive.
A normal hive you shouldn’t treat like that for the risk arousing their temperament in a very bad way. They could start chasing yourself and all that are around you as well as neighbors.
I soon realized the bees didn’t care and I was both surprised and glad of course. This colony on the pictures is a split from one of my breeders this year. It reared their own queen, grew quickly in strength, gave some honey and ended up on three 12 frame square shallow boxes for winter packed with bees. The breeder colony is on its third season without any treatment of any kind and had a varroa level of 0% in May. The temper was good, but the temper of the split is even better, not a bee flying up at this bashing treatment. And no sign of any virus problems. In spring I will monitor the varroa level in this one and several others.
I tried to take a selfie together with the colony just after the bashing, but it wasn’t that easy to get a good shot with one hand. But you see a little anyway.
