I have 2 hives that both made it through the Minnesota winter. Both hives are 3 brood boxes deep. One of my hives has mold in the comb of the bottom box. Should I remove these frames or will the bees clean the comb? Some of the frames have capped honey.

I started running quilt boxes year round after having problems with mold my first year. I suspect the bees will eventually clean out the mold but I would rather not have any mold in the first place.

They will clean it up eventually. If possible, I would rotate in a few moldy ones at a time. Maybe 1 pr/deep. I think they will clean them up faster and will lessen any ill effects of a mold overload, although I don't know if it harms them at all. See if you can think of why that hive has mold and the other doesn't and take corrective action before next winter. Most likely reasons is ventilation,physical location and undried nectar/honey. Like Mr. Fudd said, maybe a quilt box is needed. J
