Abstract:
1. A method of preventing vermin from boarding or disembarking a ship having a mooring line attached to a dock, the method comprising the steps of: a) providing a rat guard having a shield connected to electrical circuitry and defining a central opening with a radial slot sized to receive the mooring line therein, the central opening being in communication with the radial slot, an electric grid connected to the electrical circuitry and defining an outer surface completely exposed, an acoustical generator connected to the electrical circuitry, and an electrical connector affixed to the shield at a location spaced away from the central opening and the radial slot; b) attaching the shield to the mooring line; c) encircling the mooring line with the exposed electric grid; d) activating the electrical circuitry; e) allowing a rat to contact the exposed electric grid; and f) shocking the rat with the exposed electric grid to deter progress along the mooring line.
