Mini Size, Maximum Coverage

While these ultrasonic repellents may be small in size, they possess powerful rodent repelling capabilities. Victor PestChasers are the ideal tool for repelling mice and rats from a variety of medium-sized rooms including kitchens, bedrooms, living rooms, bathrooms, and more! The high-frequency sound emitted by these repellents is inaudible to humans, but very irritating to rodents. The sound cannot travel through walls, so for the best results, place several throughout your home to provide maximum coverage and protection.
