The upgraded version of ultrasonic mosquito repellent uses the latest ultrasonic frequency conversion technology, which can intermittently emit four different frequencies of ultrasonic waves.Compared with other ultrasonic mosquito repellent, l Ultrasonic mosquito repellent makes it more difficult for parasites to produce “adaptability” and “immunity”. “Strength”, the expelling ability is more powerful and efficient. Ultrasonic anti-insect dual chip intelligent technology has become a professional intelligent dual chip, which can not only automatically generate ultrasonic waves at variable frequency, but also emit bionic waves to simulate cries between mice or other parasites, and double-stimulate parasites such as mice and mosquitoes. They could not stand it and could only run away. Ultrasonic insect repellent uses purely physical, non-toxic and tasteless mosquito repellent technology, the ultrasonic waves produced mainly attack the hearing system and the system nervous parasites,
