ABSTRACT:
A method whereby a low frequency, randomly varying magnetic field is generated by a device such that it interacts with the earth's geomagnetic field to eliminate rodents and similar pests both above and below ground which inhabit an area surrounding the device. The method is not limited to, but may comprise an electro-magnetic system that energizes and de-energizes one or more of a plurality of electric coils according to a predetermined sequence, thereby generating a specific low frequency magnetic field over a defined zone of influence. This magnetic field modulates and interacts with the earth's natural magnetic field (the geomagnetic field) thus inducing remanent defensive instinct responses in rodents and similar pests residing within the zone of influence. The effect, of the method, is to interfere with the pest's primitive survival and navigational instincts necessary for survival. When these primary instincts are interfered with in this manner, the pest becomes severely disoriented and eventually ceases to eat, drink and reproduce. The result of employing the method is that the pest dies from dehydration and starvation.
