Japanese Honeybee Hive - Nihon Mitsubachi - Japanese Honeybees - Stacked Hive - 5 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. Inspection can be easily done 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 traps, Varroa mite treatments, and winter feeders. Eight metal rods are included as a measure to prevent honeycomb collapse; instructions for use are included in the letter containing honeybee 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.
