OverviewHow it works: Ultrasonic insect repellent uses dual ultrasonic waves and electromagnetic chips to work at the same time to disorient the pest's auditory and nervous systems, thus driving them away quickly and powerfully. It can scare away most types of flying and crawling pests such as mosquitoes, spiders, bed bugs, cockroaches, rats, fleas, ants, fruit flies, etc. Five levels: CF fixed frequency mode, VF frequency conversion mode, CF fixed frequency + LED light drive, VF frequency conversion + LED light drive, silent driving It works best: some pests have some adaptation to the environment. When the sound waves are fixed at a certain frequency, some pests can adapt to the sound waves and cannot move away. Therefore, different frequencies of sound waves + light can repel pests more effectively Wide coverage: effective area up to 1600 square feet; Put one in each room, because ultrasound cannot penetrate walls and solid objects Hygiene: Ultrasonic household insect repellents are safe even for pests because when the device is turned on, they leave your area without you finding dead insect carcasses throughout the morning
