Safe Ultrasonic Repeller: The animal repellent uses ultrasonic technology to scare away intruders without harming them. When the animal approaches, a highly sensitive infrared sensor detects the intruding animal and emits high-frequency ultrasonic waves that repel the animal. Very effective against mice, foxes, raccoons, skunks, rodents, wild boars, martens, etc., and is harmless to humans, pets, and poultry. Ideal for gardens, farms, and greenhouses. Wide Effective Working Range: The PIR infrared motion sensor has an angle of up to 110 degrees and a detection range of up to 10 meters. With the updated repellent design, there are two horns that emit powerful ultrasonic waves, effectively driving animals away from the detected area. As soon as the animals reach the protected area, the PIR sensor starts working, emits ultrasonic waves, and the red light turns on, repelling the animal. Solar Mole Repellent: The cat repellent is powered by solar cells, no need for additional batteries.
