Features 1. Electric shock mosquito killer lamp, indoor and outdoor USB charging mosquito repellent, mosquito killer, mosquito trap lamp. 2. The electromagnetic bug repellent heater utilizes ultrasonic and electromagnetic wave technology to prevent your home from being invaded by bugs. It can prevent your home from being invaded by bugs and eliminate the worry of being bitten by bugs in your daily life. 3. Ultrasonic technology: The bedbug electromagnetic deworming heater is designed to emit ultrasonic waves with a sensitive frequency or higher, which can interfere with the normal communication of target pests (such as communication and foraging), disrupt their normal communication, and thus affect the target pests. The navigation system of pests makes it difficult for them to accurately locate their targets, thereby reducing the frequency of invasion. It is also safe and harmless, avoiding the use of toxic chemicals, ensuring that it does not cause harm to people, animals, or the environment. 4. Electromagnetic technology: The stink electromagnetic deworming heater sends electromagnetic waves to the target area, interfering with the nervous and sensory systems of the stink bug, affecting its sensory and motor abilities, including vision and smell. As a result, their perception of the environment will be disrupted, and they will leave the target area. 5. Quiet and harmless: The stink electromagnetic insect repellent uses special acoustic shielding technology to shield and kill pests, achieving a silent insect repellent effect. This method utilizes technological means to block the propagation of sound waves and maintain a quiet environment. Ensure environmental safety and quietness through micro release or chemical encapsulation technology.
