How Does Plug-In Pest Free Work?

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 electromagnetic field created by the 50Hz supply at the frequency of these "Bursts", as the coil is switched "On" and "Off".
