- Intelligent Frequency Conversion: The JUCHENG ultrasonic pest repeller utilizes advanced automatic frequency conversion technology, emitting ultrasonic waves between 20-55KHZ. This effectively disrupts the auditory and nervous systems of common pests such as mosquitoes, cockroaches, mice, and mites, driving them away from your living space. - Safe for Humans and Pets: Operating at ultrasonic frequencies above 20KHZ, this repeller is inaudible to humans. When placed out of reach of sensitive animals, it poses no harm to pets like cats and dogs, allowing you to protect your home without compromising their safety. - Wide Coverage Area: This device is designed to protect indoor spaces up to 80-120 square meters, making it ideal for use in homes, offices, warehouses, supermarkets, and hotels. For optimal results, install one unit in each room, as ultrasonic waves cannot penetrate walls. For areas with severe infestations, consider using two or more units. - Easy Installation: Simply plug in the JUCHENG spider repellent to activate it. Position the device 10-30 inches above the floor, ensuring there are no obstacles within a 1-meter radius for maximum effectiveness. Note that the device will not offer protection to adjacent rooms if it is installed in only one area. Applications: - Use in residential areas to maintain a pest-free environment, ensuring comfort and hygiene for your family. - Ideal for offices to create a productive workspace free from distractions caused by pests. - Effective in commercial settings like supermarkets and hotels, enhancing customer satisfaction by providing a clean, pest-free atmosphere.
