This device emits ultra-powerful deep penetrating ultrasonic waves which prevents insects and pests from entering your home. Outdoor pests and insects will no longer try entering your home. 

  This product works by annoying pests with high ultrasonic frequencies that cause them to leave your space without using dangerous chemicals, sprays or traps that can harm you, your family, and animals. No need to clean up dead bodies. These frequencies are too high for the human ear to hear and do absolutely no harm to humans and ordinary pets.
