Construction is very simple.
This arrangement allows debris and mites to fall out of the hive and prevents invasion of other organisms. An entrance above the mesh floor is needed to allow bees to enter the colony. Because the mesh allows increased hive ventilation, only a small bee entrance is needed, which reduces robbing tendencies. No debris can collect on the floor, thus fewer wax moth larvae are provided hiding places. Unless one has Alaskan winters, Mr. Hoare says not to worry about using these floors during the colder weather.
