Our new 4 Frame Quilt Box w/ Built in Feeding Shim will help you overwinter your 4 frame nucs and Resource Hives with success! Our quilt boxes help get rid of extra moisture in the hive during the winter. We recommend using pine shavings in the top of the quilt box to wick away moisture. Check every few weeks and change out the wet shavings when needed. Our 4 frame Quilt Boxes integrate perfectly with our 4 frame Resource Hives.
