ATTACK WAVE RAT REPELLENT is effective in controlling mice, rats, roaches, crickets and most of the other common pests. ATTACK WAVE RAT REPELLENT is a device with auto-changed and auto-sweeping high intensity frequency range of 30,000Hz to 65,000Hz. The unique circuit design strikes the auditory and nervous systems of the rodents strongly with its intensive ultrasonic waves. This function is effective to prevent rats from immunity to a pre-selected single sweep rate. With 130 decibels of intense ultrasonic sound pressure, rats will give up their source of food, water and shelter and move on. These high-intensity sound waves are out of the range of hearing of human beings and most household pets.
