Pest Free when in operation, alters the background of the existing Electromagnetic Field already contained within a buildings structure.
The unit operates by switching a coil across the Active and Neutral leads of the electrical supply wiring. This produces short Bursts of electro motive force at 50Hz, which feeds down the wiring effectively modulating the existing electro-magnetic field created by the 50Hz supply at the Frequency of these Bursts, as the coil is switched on and off.
The Pest Free Technology will not effect cats, dogs, birds, computers or the electricity flow in a building. It is Family Safe, Environmentally Responsible, and long term cost effective and maintenance free.
