Colorado winters can be tough on your bees. While bees are in cluster inside the hive during winter, they are creating heat and moisture. The moisture rises and typically, will collect on the inner cover, only to later rain down on your bees and get them wet...then the temperature can drop and they freeze to death. The Quilt Box removes the excess moisture in your hive. Line the bottom of the quilt box with untreated burlap a few inches up the sides, but below the vents and fill with an absorbent material such as wood shavings. Place on your top box, then on top of the quilt box, place your inner cover and telescoping lid. If using in conjunction with a candy board, place the Quilt Box on top of the candy board.
