2020 Latest Ultrasonic TechnologyWith intelligent double-chip design, the ultrasonic insect repeller stimulates the auditory nerve with ultrasonic in the frequency range of 20kHz-65kHz and destroys the central olfactory and nervous system pests and rodents. This type of ultrasound can make rats, spiders, flies, fleas, ants and other types of rodents and insects very uncomfortable, driving them out of our homes and habitats.
