The device utilizes advanced microelectronics technology to emit a dual-wave system combining ultra-low electric frequency electromagnetic waves with upgraded variable high-frequency ultrasound (22–65 kHz). This setup targets the highly sensitive hearing and nervous systems of common pests, making them restless and forcing them to naturally migrate out of the area because they can neither reproduce nor grow within the control zone.

No, they cannot. The unit features an intelligent chip with smart frequency cycling and conversion technology. It constantly shifts the ultrasonic patterns and acoustic waveforms automatically. This continuous variation prevents mosquitoes, rats, cockroaches, and other intruders from adapting or developing an immunity to the sound, ensuring a reliable, long-term 24/7 repellent effect.

Yes, it is 100% eco-friendly and safe. The variable high-frequency sound waves emitted (22–65 kHz) are entirely outside the hearing range of humans, cats, and dogs. It is completely non-toxic, chemical-free, radiation-free, and odorless, making it perfectly safe for environments with children, expectant mothers, and standard domestic pets. (Note: Avoid using it in rooms where rodent pets like hamsters or guinea pigs are kept).

Not at all. The device is explicitly engineered for silent operation to complement your daily activities and rest. It works quietly in the background without producing any audible hum or buzz. Additionally, its simple design style allows it to fit seamlessly into bedrooms, living rooms, or kitchens, providing round-the-clock protection without disturbing your sleep cycle.

A single plug-in unit effectively covers a wide area of 10–30 m² in an open space. However, because ultrasonic waves travel via radial sound and cannot pass through solid walls or heavy furniture, we highly recommend installing one unit per individual room. For much larger rooms or areas prone to heavy pest activity, using multiple units simultaneously will ensure complete coverage.
