-- We deeply studied the physiology and habits of mites and found that the auditory nerves of mites are very fragile. It is very sensitive to ultrasonic waves of special frequencies. In response to this feature, we have researched and developed a mite removal device. -- Using microelectronics technology to use special frequency ultrasound to act on the central nervous system of the mites, so that they stop breeding, stop eating, quickly escape from the parasite or gradually die. Features: Rid your home of pests using completely safe and non-toxic ultrasonic waves and pulses. The large area of the whole house can remove mites, and the ultrasonic coverage area can reach about 50 to 100 square meters without obstacles. 1. The Multifunction ElectroSonic Pest Repeller utilises ultrasonic frequencies to deter common household pests. 2. Undetected by humans, these frequencies aggravate small rodents and insects without any toxic chemicals, making it completely safe for use within your home. 3. Sound waves and pulses remain undetected by adults, children and pets. 4. Deter rodents, cockroaches, flies, mosquitoes and more. 5. Doesnt require any refills just plug in for long-term protection. 6. Place in the home, outdoor shed, cafes, kitchens and more.
