Q1: How do you overwinter double nucleus colonies?
A1: At the University of Guelph, we winter our double nucleus colonies indoors. You can also winter them outdoors by wrapping two double nucs together with insulation on the sides and top.
Q2: Are double nucleus colonies prone to swarming?
A2: With a young queen in the nucs and honey supers above we don’t have any problem with these nucs swarming in the first year. We do have to transfer them into a full size box early enough the following spring to prevent swarming.
