22-65 kHz Ultrasonic Rodent and Insect Repellent, Powerful 4-Pack Frequency Changing Pest Repellent for Versatile Use Against Rats, Mice, Ants, and Cockroaches

[Variable Frequency] The latest powerful 5W repellent is designed to emit ultrasonic waves from 22-65kHz. In addition, our repellent features a real-time visual display of the ultrasonic frequency. To prevent interference from being used with a fixed frequency, the microcomputer automatically changes the frequency intermittently, making the product both effective and intuitive. [Scary Lights] According to experiments, mice are inherently very resistant to light and prefer dark and humid environments. Therefore, our mouse repellent flickers through lights to scare mice away (brightness adjustable to 3 levels). This is different from other mouse repellents on the market, making our product more effective. [Large Coverage Area] Each electronic ultrasonic repellent is effective over a large area, making it much more powerful than other, cheaper repellents. Please note that ultrasonic waves cannot penetrate walls. Although our insect repellent works well, if you have a large infestation, we recommend placing it in every room. [Safe and Silent] Non-toxic and eco-friendly ultrasonic repellent, our repellent is 100% safe and effective. The ultrasonic frequency emitted by this machine is inaudible to humans and pets. Safe for children, family, and pets. Indeed, a great way to get rid of the hassle of rats and pests. [Easy to Use] This machine should be installed 20-30 centimeters from the ground, vertically on the ground, and plugged into an outlet. It can be plugged directly into a 220V AC outlet. It can be widely used in homes, warehouses, shops, hotels, hospitals, offices, etc. Save as much as possible on your costs.
