The insect repellent detects movement through a passive infrared sensor (PIR) and triggers an ultrasonic speaker to scare away unwanted animals and pests, thereby emitting a mixture of ultrasonic waves, sound waves, and powerful LED strobe lights. Irregular and variable frequencies can more effectively drive the most aggressive animals that may adapt to and immune to a certain frequency band. The dual speaker design and motion sensors extend the acoustic coverage to 5,000 square feet. The left and right angle of the radiation range is 210 degrees. Once the animal enters the 30-foot animal repellent, the motion sensor will emit ultrasonic waves, and the LED lighting will make the animal feel uncomfortable and run. Solar powered and waterproof-Chasehill mosquito repellent is equipped with a solar panel on the top, which can be charged by solar energy in the sun, or powered by a USB charging cable in rainy days. IP44 waterproof design makes it work normally in any weather conditions, perfect outdoor user experience. Effective and environmentally friendly-Ultrasound makes the animal feel uncomfortable and run away, while the strobe will only scare the animal. No traps, no killings, no pollution. But please keep the product away from children and infants' activity areas. Point the repellent at the area you want to protect, select the mode you want, and then carefully insert the spike into the ground where there is plenty of sunlight and turn it on.
