Welcome to our shop 2020 Latest Ultrasonic Technology: With our intelligent double-chip design, our ultrasonic insect repeller utilizes ultrasonic waves in the frequency range of 20kHz-55kHz to stimulate the auditory nerve of pests and rodents. This destroys their central olfactory and nervous system, making them very uncomfortable and driving them out of our homes and habitats. It effectively repels rats, spiders, flies, fleas, ants, and other types of rodents and insects. Environmentally Friendly and Harmless to Humans: Our pest control device emits ultrasonic waves that are invisible and harmless to humans and pets. It is non-toxic, radiation-free, and environmentally friendly. The ultrasonic protective agent is 100% safe and has low power consumption. Wide Coverage Area: Our ultrasonic repeller can cover an area of 80-120 square meters. However, please note that ultrasonic waves do not penetrate walls. For optimal results, we recommend using at least one device per room. The ultrasonic repeller is suitable for homes, offices, garages, attics, basements, warehouses, and greenhouses. EASY TO USE: Simply plug the Pest Killer into an electrical outlet, making sure it is at least 12 inches above the ground. It can be used in any powered area of your home, such as kitchens, bedrooms, basements, garages, and warehouses. 100% Satisfaction: Our customers are our top priority.
