Abstract

See full text

A rat guard and method utilizing a flexible shield affixed to a plastic sheath positioned on a mooring line to prevent entry onto or exit from the ship by vermin. An electric grid is positioned on an insulated pad on the sheath which is electrically connected to the shield for receiving power from an acoustical generator also connected to the shield and spaced therefrom. The acoustical generator directs ultrasonic acoustic signals in a variable frequency range toward the shield to frighten rats or other vermin therefrom. Should the acoustical signals not deter the vermin, the electric grid will shock any vermin making contact therewith to cause harm and frighten. The shield provides another obstacle to prevent advancement and is affixed to the sheath on the mooring line. The shield is flexible and remains in place during high winds and other adverse weather conditions.
