It uses 18 variable-frequency ultrasonic wave patterns designed to create an uncomfortable environment for mice, rats and common crawling insects. The changing output helps reduce the likelihood of pests becoming accustomed to a single, constant frequency.

Results depend on the type of pest, the level of infestation and the room layout. Some activity may initially increase as pests leave their hiding places. For best results, keep the device operating continuously and allow several weeks to assess its effectiveness.

Ultrasonic waves do not travel effectively through walls, closed doors or large furniture. We recommend using one unit per affected room and positioning it in an open, unobstructed wall socket close to where pest activity has been noticed.

No. The device is designed to help deter pests using ultrasonic technology, without poison, chemical sprays or disposable traps. It is intended as a cleaner supporting solution and should be combined with good hygiene, sealed food storage and blocked entry points.

The device does not use poison or chemical bait. However, ultrasonic frequencies may be detectable by some animals, particularly rodents kept as pets, rabbits and other small mammals. Do not install it near pet cages, and discontinue use if any animal appears uncomfortable.
