ABSTRACT:
A pair of strips formed of dissimilar materials, such as copper and zinc for example, are disposed along a surface to define a zone which inhibits the entry of snails, slugs or the like. The dissimilar materials are ones which exhibit different electrode potentials or voltages when in contact with an electrolyte. It is believed that the exudate or slime present on the skin of a snail or the like has electrolytic characteristics and electrochemical reactions occur when the body of the snail or the like spans the dissimilar strips which reactions are sensed by the snail and discourage further progress. The barrier may be preformed as a flexible, adhesive coated ribbon or tape with the two electrically conductive strips extending along opposite edge regions of one surface of the tape.
