Mason Bee House - Natural Wood Bee Nesting Block with 35 or 56 Holes for Pollination - Perfect for Garden, Backyard, and Outdoor Bee Habitat

These nesting blocks are made locally in our wood shop, available with either 35 or 56 holes. The generous spacing between the holes helps prevent the spread of disease and slows down parasitic wasps.  The back of the layers are bonded with high strength resin impregnated fabric to help keep the keep the layers together when harvesting and cleaning.   All of this makes for a sturdy, secure and well built nesting block.
