Abstract: The present invention relates to the use of a chemical foaming agent as insulation for a cylindrical plastic wood duck house. A second aspect of the present invention is the inspection door that fits snugly into a depression of matching size on the side of the cylindrical wood duck house. A third aspect of the present invention relates to securing the wood duck house to a round plastic PVC pole. The neck at the base of the wood duck house rests atop and over a round plastic PVC pole of slightly smaller diameter. The security collar of the present invention snaps snuggly onto the neck of the wood duck house. The peg on the inside security collar fits into an opening on the neck of the wood duck house and then through an opening on the round plastic PVC pole. The peg on the security collar acts as a spear through the neck of the wood duck house and the pole to stabilize and secure the wood duck house to the pole.
