Chisel-shaped incisors grow for life, so they have the habit of grinding teeth and punching holes. Most rodents feed on plants, especially young shoots with higher water content, and mature seeds.Rodents communicate with ultrasound,and their auditory system is so developed that they are very sensitive to ultrasound.   Principle The use of high-power ultrasonic pulses to effectively interfere and stimulate the rodent's auditory system, making it intolerable and panicking, showing symptoms such as loss of appetite, escape, and even convulsions. Thus, the purpose of driving rodents out of their range of activities can be achieved.The auditory system of rodents is between 200Hz-90000Hz.(Reference: Fay 1988, Warfield 1973, and The Nature of Sound)  Our Mole Repellent emits a 3-second 400 Hz sound pulse per 30 seconds to the surrounding area. Causes physical discomfort to Moles and produces fear.   Easy to use First, punch a hole in the ground. Next, press the "On/Off" button. Then, insert the spike into the soil so that the lid is flush with the ground. Finally, the compacted soil can be used normally.   PS: The denser the soil, the better the effect. Loose soil isn’t conducive to the transmission of sound waves. As the distance is farther, the frequency doesn’t change, but the loudness becomes smaller, so the farther the distance, the smaller the effect. It is strongly recommended to install one device per 50 feet.
