Essential in the North for wintering wooden hives, this product is placed under the Galvanized Telescoping Outer Cover. An inner cover allows moisture to escape and fresh air to be circulated throughout the hive when used properly with an outer cover. This lowers the moisture content of the nectar stored in the comb. Our inner cover has a notch in the rim, allowing the bees to have a top entrance or exit.
