Sonic Barrier: ultrasonic repellents for gardens and outdoor spaces

Sonic Barrier is an online retailer specialising in ultrasonic animal repellents. The company presents its devices as a humane alternative to poisons and traps, using targeted sound frequencies, light and motion to encourage animals to leave a garden rather than harming them. Its catalogue is organised by type of animal, covering domestic and feral animals, birds and flying pests, insects and arthropods, rodents and small mammals, and wildlife, predators and scavengers.

How the repellents work

According to the company, each model is tuned to the hearing range of a specific pest species, which it describes as the basis for its effectiveness. The devices use infrared sensors to detect movement and emit ultrasound only after a short delay, for a few seconds at a time. Sonic Barrier states that the sound is generally inaudible to adults, although younger people or those with sensitive hearing may perceive a high-pitched tone when the device activates. The company also notes that target animals may take two to four weeks to associate the ultrasound with discomfort and adopt avoidance behaviour, and that territorial attachment can delay the effect.
