I had a russian hybrid colony that became so mean it was terrible. It was a very strong and productive colony,but mean as all get out.
I thought Id go through the hive and per her, but with the large number of angry bees it was futile. I took probably fifty stings through the pants before quitting for supper.
I had contemplated going out and burning it to the ground, but then thought better of that idea.
I thought well, divide and conquer. I set up another bottom board a few feet away and just hastily took half the boxes off and placed on the other bottom board.
After considerably more stings and a cloud of bees hovering around me I got the task accomplished.
I left them alone for a couple days and never had any trouble after that. They both survived the ordeal and I either had multiple queens in one box or transferred enough fresh eggs that box 2 was able to requeen itself.
I know this is an extreme case,but the harvest made it worthwhile.
And I dont know if it was the Russian traits or something else, but I lost my interest in that breed. And I know a lot of people keep them without incident.
Next time I have a hive like that ,regardless of breed, it will be dealt with differently.
