Upgraded Ultrasonic Technology: Our intelligent frequency technology continuously alternates ultrasonic frequencies 24 hours a day. By emitting ultrasonic waves that irritate the brain and auditory nervous system of pests, it effectively repels mice, fleas, cockroaches, ants, spiders, mosquitoes, bed bugs and other common pests. Safe for the Whole Family & Pets: Protect your home without harsh chemicals! This ultrasonic repellent physically targets pests only – completely harmless to kids, pregnant women, seniors, and furry friends. Zero interference with electronics, silently working, and radiation-free for total peace of mind. Plug & Protect Convenience: Super simple setup! Just plug it into any standard wall outlet (best 10 ~ 47 inches off the floor). Runs whisper-quiet,no mess, no fuss, just effective protection. Wide Coverage Area: One unit effectively protects rooms up to 1200 square feet. Since ultrasonic waves cannot penetrate solid objects, we recommend using one device per room and keeping the area around the device clear of curtains, furniture, and other solid obstructions. Visible results can generally be expected within 3–4 weeks. Wide Application & Energy-Smart: Ideal for use in living rooms, bedrooms, kitchens, garages, apartments, offices, basements, and even tool sheds! Consuming less power than a night light (only 3–5W), it provides continuous, effective protection against pests while saving energy. White 6pacs
