Electromagnetism technology works by emitting low-frequency electromagnetic waves throughout the designated area. These waves create an electromagnetic field that extends along the specified area, effectively covering it. Pests like rodents, which are sensitive to changes in electromagnetic fields, find this disturbance uncomfortable and will often seek to avoid areas where these waves are present. Essentially interrupts their usual behavior patterns, making the protected zone less attractive to them.

Ultrasonic waves, which are high-pitched sound waves beyond the range of human hearing but well within the hearing range of many pests, such as rodents and insects, are harnessed by the PestShield Ultrasonix Mini Repellent. This device emits ultrasonic waves at frequencies that prove to be both irritating and disorienting to pests. This discomfort encourages pests to vacate the area in search of a more tranquil environment.
