  • Insect guard system and method of use
    Patent number: 5007196
    Abstract: A non-toxic, non-chemical device and system for repelling crawling insects from a structure such as a building and training the insects to go elsewhere includes closely-spaced elongated conductors mounted on an insulating base and having a potential difference applied thereto for providing a insect-stunning short-circuit current of about fifteen microamps. When insects bridge the conductors, they receive a current as a function of their internal resistance. The conductors are mounted via the base along the foundation and about posts and other structures which connect into the building. Preferably, the conductors are also slippery and reflective to assist in repelling and training the insects without bridging the conductors.
    Type: Grant
