Abstract: An aerial rat/rodent guard for residential/commercial utility wires and cables and the like. A barrier plate manufactured from lightweight, non-conductive, smooth surfaced materials molded into a tear drop shaped plate. The center slot is located above the center of gravity allowing the plate's upright position. Removable grommets in the center slot provides the size of the center slot to be adjusted to the size of the utility wire upon which it hangs. A slit opening from the center slot downward to the bottom of the plate provides easy installation. Weight molded into the bottom quarter of the barrier plate allows the barrier plate to return to an upright position if tampered with by a rat/rodent. With the slit closed, a tail clip is attached to the bottom of the barrier plate which locks the slit in a closed position. Once mounted on the wires or cables, without the necessity of tools, the aerial rat/rodent guard does not need to be removed.
