•This product adopts modern scientific and technological methods, which can produce ultrasonic waves, pressure waves and night-time strobe effects, stimulating the nervous system and auditory system of mice and other pests, causing them to feel uncomfortable and flee the scene. Since the frequency of the radio waves generated by this product constantly changes intermittently, it will not cause "adaptation" and "immunity" to pests such as mice. •Multi-function: It can produce variable frequency and super fixed frequency ultrasonic waves and pressure waves at the same time, and it can also produce variable frequency strobe lights at night. •Frequency conversion: The frequency of the various radio waves generated by this product constantly changes intermittently. The three flashing frequencies of the strobe light work alternately, so that pests such as mice will not be "adaptable" to a certain fixed frequency. "Immunity". •High power: This product maximizes the output power of the two radio waves and provides 360-degree output without dead ends.
