Ultrasonic Pest Repellers (6-Pack)

The Ultrasonic Pest Repeller produces highly effective ultrasonic frequencies that force rodents and insects out of your home. Variable frequency technology ensures that pests do not become used to the sounds. Chemical-free and odor-free, it works on mice, rats, spiders, ants and roaches. Set includes 2 micro size repellers (for countertops), 2 medium repellers (for hallways, basements and attics) and 2 large repellers (for bedrooms and living rooms).
