Ultrasonic Solar Cat Fox Dog Rodent Garden Animal Repeller with Pir Motion Sensor
The sonic repeller produces ultrasound at constantly changing frequencies to frighten away animals. The sound waves and bright LED light activate when an animal enters the PIR Sensor range. The coverage can be easily adjusted using the sensitivity dial, up to a maximum of 2425 square feet. Whilst the deterrent will start protecting your garden from day one, it may take time for persistent pest animals to 'learn' to stay away. Ultrasonic waves behave in a similar way to light waves; they will not travel through solid doors, walls and furniture. Nor will they penetrate into nesting sites beneath flooring or within ceiling and wall cavities.
