Japanese Honeybee Hive - Nihonmitsubachi - Japanese Honeybee Stacked Hive - 3 Tier - 30mm Thick Boards Made using naturally dried cedar wood. As a countermeasure against the recent heat, the bottom board can be replaced with either the standard type or a 6mm mesh wire type. Internal inspection is easy by removing the bottom board and using a smartphone, mirror, etc. The upper part is made of plywood with slits to accommodate wax moth, Varroa mites, and a winter feeding box. Four metal rods are included as a measure to prevent honeycomb collapse; instructions for use are included in the letter containing bee-attracting know-how. Although we strive for high precision in manufacturing, there may be slight dimensional errors due to handwork and warping of the wood. Thank you for your understanding.
