Does the insulation need to be removed in summer or maybe cause they like it warm it's even an advantage in summer?
Discussion
Several have said it’s fine in the summer too. I didn’t see any temperature issues myself. This is the temp chart for an insulated nuc for last summer and the bees kept it pretty reasonable.

This is how I’ve been working to solve the winter problem. Roughly 2 inch insulation on sides and top but still using Langstroth frames. Didn’t do the bottom last year and that’s why I think 2/3 of the nucs didn’t make it. #bees #grownostr
