General Description The JUCHENG Ultrasonic Pest Repeller uses automatic frequency conversion technology to emit ultrasonic waves from 20 to 55 kHz. These waves stimulate the auditory and nervous systems of rodents and other pests, such as mosquitoes and cockroaches, to effectively repel them from your home. This device is safe for humans and pets, provided it is placed outside the hearing range of cats and dogs. Technical Specifications Ultrasonic Frequency: 20 to 55 kHz Coverage Area: Up to 80 to 120 square meters Number of Units: 4 Installation Install at a height of 25 to 76 cm (10-30 inches) from the floor. Avoid obstructions within 1 meter. Simple Connection: Works as soon as it is plugged in. Usage For optimal effectiveness, it is recommended to install one unit in each room, as ultrasonic waves do not penetrate walls. This repellent does not require cleaning up dead pests, does not produce unpleasant odors, and does not require batteries, thus saving money.
