HOW IT WORKS: Our mosquito repellent uses ultrasonic technology to target the brain neurons of pests. Prolonged exposure to these ultrasonic waves disrupts the pests' nervous system, effectively driving them away without harm. EASY TO USE: Simply plug our mouse repellent into any standard outlet. You’ll hear a “beep” sound and see a calming blue breathing light, indicating that the device is active. Results are typically noticeable within 2-4 weeks, and you can say goodbye to pests for good! Note: It’s normal to see an initial increase in pest activity during the first 2 weeks as the device drives them out of their hiding spots.
