RatGuard ® Repeller - Ultrasonic Rats and Mice Deterrent

Our device is designed to emit ultrasound precisely targeting the auditory range of rodents. The effectiveness of our devices is unmatched thanks to this optimization, which is necessary to guarantee their function but is absent from some devices sold online.

Scientific studies have demonstrated the effectiveness of ultrasonic repellents in deterring rodents by targeting the correct auditory spectrum. To find all the studies, we invite you to consult our page dedicated to scientific studies on the subject .

Our devices are designed to emit ultrasonic frequencies within the hearing range of the targeted pests. While these sounds are generally inaudible to adults, some individuals—especially younger people or those with sensitive hearing—may perceive a brief high-pitched sound when the device is activated.

That said, the device only triggers after a short detection delay via its infrared sensor, and the emission lasts only a few seconds. If you are indoors or not directly facing the device, you are unlikely to notice anything. Even outdoors, most people report little to no disturbance unless they stand directly in front of the device when it activates. Overall, it is designed to minimize any discomfort for humans while remaining effective against animals.

The ultrasonic frequency is calibrated for rodents, so the device may also affect squirrels, hamsters, and other rodents in addition to mice and rats.

If any problem occurs, please contact our customer service. We promise to respond to you within 24 hours. All our repellents are also covered by a 30-day money-back guarantee.

To use this rat repellent effectively, start by identifying areas where rodents are likely to enter or travel, such as kitchens, garages, or basements. Plug the device into an electrical outlet as close as possible to the area you want to protect, then click the button to set it to Ultra (ultrasonic mode). Make sure the device emits ultrasound without obstruction, as furniture or walls can block the waves. The product works continuously, emitting ultrasound that disturbs rats and encourages them to leave the area.
