4-Pack Ultrasonic Mosquito Repellent Ultrasonic Electric Insect Reptile Repellent Ultrasonic Insect Insect

2020 Latest Ultrasonic Technology: - With intelligent dual chip design, Ultrasonic Insect Repellent stimulates the auditory nerve with ultrasound in the frequency range of 20kHz to 65kHz and destroys the central olfactory system and nervous system of 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. Environmentally friendly and safe for humans: - This type of pest control is used to drive away pests by emitting ultrasonic waves. However, these ultrasonic waves are invisible and harmless to humans and pets. Electronic mosquito repellents can emit non-toxic ultrasonic waves without radiation. The ultrasonic protection agent is 100% safe, environmentally friendly, and has low consumption. Large Coverage Area: - Ultrasonic repellent works in an area of 80-120 square meters, but ultrasound does not penetrate walls. We recommend that you use at least 1 device per room. Ultrasonic repellent is ideal for homes, offices, garages, attics, basements, warehouses and greenhouses. EASY TO USE: - Just plug the pest killer into an electrical outlet (at least 12 inches above the ground) to serve. This pest killer can be used in any home that can get power, like kitchens, bedrooms, basements, garages, warehouses, etc.
