I thought I would share with ya'll one of the steps I take in keeping varroa counts down.
Years ago, I did the green drone frames/ freeze thing, and came to consider it a waste of hive resources.
Then one day, I was reading some wise words written by Laurie, and saw how she cut her foundation to make cut comb.
Well, second year hives don't draw worker cells in open space but rather Drone....
so I began cutting 1/3 off a foundation, mark the frames topbar for easy visual, and now just harvest the capped drones-- ergo, harvest Varroa.
This time of year it takes only a week for the comb to be redrawn and relaid anyway.
