A powerful ultrasonic repellent, inaudible to humans - safe to use near children, cats & dogs.

Sonic Mouse & Rat Repeller produces over 100 decibels of ultrasound at constantly changing frequencies which are too high for humans, dogs or cats to hear, but which are within the hearing range of mice and rats. Each unit protects an area of at least 37 square metres (400 square feet) from rodent infestation.
