The ultrasonic range is completely harmless to humans and animals. Efficient Solar Charging: Powered by solar cells, no additional batteries are required. The device automatically harnesses solar energy during the day to operate continuously at night, preventing unwanted visitors from entering your premises. It is IP65 waterproof and weatherproof, allowing you to place it anywhere outdoors. This animal repellent works 24 or 7 and is ideal for outdoor areas such as gardens, yards, patios, garages, driveways, farms, ponds, and attics, effectively protecting your property.

Features: Ultrasonic waves stimulate and simulate danger to drive away pests from the irradiated area. Ideal for keeping snakes away using sonic and vibration technology to protect your garden or lawn. The multi-pulse repeller constantly changes ultrasonic pulses to prevent snakes from becoming accustomed to it and approaching your garden. Aluminum construction is a better conductor that repels vibrations, and when buried underground, it sends warning pulses through the soil. Installation: Attach the two connectors in the aluminum rail to the connection above, ensuring that the colors match: red to red, black to black. Secure the stem and top together. Place the pole on the ground, being careful not to use excessive force to avoid damage or obstacles. The top base should remain open to the outside, and keep the upper part about 5 cm from the ground to prevent exposure to heavy rain. Packing List: 2x Solar mouse repeller
