Method for using a rat guard

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 non-absorbent flexible shield defining a central circular opening with a radial slot sized to receive the mooring line therein, the central circular opening being in communication with the radial slot, a micro-hook material attached to the shield proximate the central opening and radial slot, a sheath for affixing to the mooring line, a grid pad for attaching to the sheath, an exposed electric grid for encircling the mooring line about the grid pad, an electrical connector affixed to the shield via a male plug, an acoustical generator in communication with the shield, and electrical circuitry positioned within the acoustical generator and attached to the electric grid, the acoustical generator and an adjustable discharge capacitor;
• b) attaching the sheath to the mooring line;
• c) attaching the grid pad to the sheath;
• d) attaching the shield overtop the sheath on the mooring line;
• e) encircling the grid pad with the electric grid;
• f) activating the electrical circuitry;
• g) allowing a rat to contact the electric grid;
• and
• h) shocking the rat with the electric grid to deter progress along the mooring line.
