Japanese Honeybee Hive - Nihon Mitsubachi - Japanese Honeybees - Stacked Hive - 4 Tier This hive uses naturally dried cedar wood. As a countermeasure against the recent heat, the bottom board can be replaced with either a 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 has a slotted plywood design to accommodate wax moth control, Varroa mites, and a winter feeding box. To prevent honeycomb collapse, 8 metal rods are included. Instructions for use are included in the letter containing bee-attracting know-how. Although we strive for high precision in our manufacturing, please understand that due to the handmade nature and warping of the wood, there may be slight dimensional errors.
