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 top part is made of plywood with slits, allowing for the placement of wax moth and Varroa mite treatments, as well as winter feeding boxes. 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 our manufacturing, there may be slight dimensional errors due to handwork and warping of the wood. We appreciate your understanding.
