Operating Instructions The Ultrasonic Rodent Repeller (URR) is effective in repelling mice and rats from buildings. Laboratory research has shown ultrasonic sound waves attack the auditory and nervous systems of most common pests, causing them pain and discomfort. At 130 decibels of sound pressure, pests will give up their source of food, water and shelter and move on. These high intensity sound waves are out of the range of the hearing of humans and most household pets, such as dogs, cats, fish and birds, and farm animals. The URR will not interfere with televisions, radios, electronic burglar alarms, fire or smoke detectors, pacemakers, hearing aids or other electronic equipment. The URR does not harm plants. The URR effectively protects an area measuring 40 sq mts. After plugging the URR in, you will notice a small red LED, which indicates the device is working properly, blinking approximately every 10 seconds. You will begin to notice the effects of the URR in just a few days – there will be an absence of rodent activity. Leave the URR plugged in all the year round, day and night, it’s really cheap to run. No more dangerous chemicals to buy – no more messy traps to clean!
