This 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 and nonrodent pets. It's humane and nontoxic but effectively chases away rodents and prevents damage and rodent-borne diseases. Under ideal conditions (few sound-absorbing materials), the repeller delivers sound to 400 square feet. This model is designed to be set on a tabletop or counter and aimed at a problem area. The device measures 5-1/2 by 3-1/2 by 3 inches, has a 6-foot cord, functions for five to seven years or more, and 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 dual speaker unit with 6' cord is perfect in rooms where outlet is blocked by furniture or drapes, and you want to place the unit on a shelf or table. 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.
