I'm not real sure I want my yard to grow anymore this year. During inspection I have started removing Queen cells. I don't know if that will stop them from swarming or not. Yesterday I cut out 10 from 3 different colonies. I don't need a lot more colonies I need their size to be bigger. I would really like to increase their honey production.
I can make splits and requeen my hives this fall.
Just a thought:
Split them with their queen cells to keep them from swarming. Let the new queens build up some then put em back together after they have gotten over the urge to swarm. You will have extra queens when you put them back together you can give or sell to someone who needs a queen. And you will have a big hive to make honey.
