Notice how green the grass is for late January. The hive sits on a think payer of polystyrene to keep out rising damp. There are wooden shields at ground level to keep the grass away. There is even a perforated metal doorway to stop the most enthusiastic mouse from seeking entry!
Inside is an extra layer of recycled insulating plastic. The majority of heat is lost up through the interior roof space and recycled polystyrene and insulating sheets helps keep the heat in. Wherever possible we try to reuse waste materials that would have otherwise gone to landfill. Mice can get in and devastate the honey comb and bees themselves.
