For use in warehouses, barns, schools, hospitals, and other businesses as well as in homes, this electronic device plugs into a wall socket and emits a high-frequency, ultrasonic sound (30 to 60 kHz) that repels rodents but is inaudible to humans, pets, and farm animals. It's humane and nontoxic but effective at reducing rodent damage and rodent-borne diseases. Under ideal conditions (few sound-absorbing materials), the repeller delivers sound to 1,000 square feet of space. Detailed instructions for effective placement in warehouses and other commercial structures are included. The device measures 3-1/4 by 3-1/4 by 2 inches. In addition to the wall-socket plug, two long screws are included to secure the device to a wall. With a life expectancy of 10 or more years, the rodent repeller carries a 90-day, full-refund satisfaction guarantee and a three-year warranty against defects.

Product Description
PestChaser emits high frequency sound (ultrasound) in a range that repels rodents from an enclosed area. The sound is loud and very annoying to the rodents, but inaudible to people and non-rodent pets. This humane, non-toxic approach to rodent control is extremely effective and affordable. The Commercial unit is excellent in warehouses, barns, hospitals, schools, or in homes where a stubborn rodent infestation exists. Twice as powerful as our standard household PestChaser. Please keep in mind that each PestChaser only works in the room it is in, as ultrasound won't travel through walls or other solid objects.
