This is the perfect kit to start with for young and old mason bee enthusiasts. The simple kit comes in just ten pieces and requires only wood glue to build. The Mason Bee House Kit includes a twelve-tube mason bee nesting site, and its mounting holes are pre-drilled. Simply place a bead of wood glue in the clearly marked grooves and snap the pieces into place. It even includes elastic bands to hold the house together while the glue dries. With an adult to oversee construction, this kit is suitable for children four and up. Clearly illustrated instructions are included.
