Plug-In Pest Free when in operation alters the background of the existing electromagnetic field already contained within a buildings structure. Plug-in Pest Free utilizes your wiring by simply sending a shifting signal through the wire, tuned to irritate the Pests Nervous system. This technology will not affect humans, pets or electronics and doesn't increase your wirings own electromagnetic energy, It simply changes the frequency to target small Pests like insects and rodents which easily pick up the changes in the electromagnetic frequencies. The signal is turned on and off every few seconds, so that the Pests can't build up a tolerance.

Insects communicate through vibrations. Electromagnetic Pest Control vibrations from Plug-in Pest Free communicate to the pests, disturbing their receptors and making them feel they are in a hostile area, where they are not welcome as a result it drives them out. Electromagnetic Pest Control confuses pests making it difficult or impossible for them to gather food, breed and build their nests, or communicate with each other.

Rodents will notice something different about their environment and will feel uneasy and avoid areas where Plug-in Pest Free is working.
