Electronic insect repeller features a smart display that combines ultrasonic, electromagnetic, and optical pest control technologies. Unlike conventional devices, electromagnetic waves can penetrate walls, providing 360-degree coverage for effective home protection. The device automatically changes frequency every 16 seconds (ranging from 20 kHz to 158 kHz), preventing pests from adapting by disrupting their nervous systems. This intelligent safety feature emits no harmful radiation or chemicals, making it safe for pregnant women, children, and pets. Low power consumption allows continuous operation without overheating. Coverage range up to 100 square meters with four variable wave modes that penetrate walls for comprehensive protection. Simply plug into any outlet and press the power button for 3 seconds to activate. An intelligent control chip automatically manages the pest-repelling frequency, ensuring safety for your family, pets, and babies. Designed to repel common household pests including rodents, mice, bats, squirrels, spiders, cockroaches, fleas, ticks, flies, wasps, ants, moths, bed bugs, and silverfish.
