  • Patent number: 6283064
    Abstract: In accordance with the present invention there is provided an elongated deterrent strip for mounting to an inanimate object to discourage birds and other pests from resting on that object. The strip comprises a base of electrically non-conductive material. The strip in lateral cross-section has peripheral edges normally lying in a plane and a raised concave center portion. The base has spaced notches along each edge to provide flexibility to the base, whereby the base may be bent both out of the plane and within the plane. The strip further comprises two electrically conductive wires secured to and extending along the upper surface of the base, over the notches. The wires are spaced so that pest's feet will contact both wires when perched on the base. The wires are connectable to an energy source so that the bird or other pest's feet will short the wires when it is perched on the strip, giving a mild shock to the pest to discourage it from continuing its perch on the strip.
