Protect lawns, flower beds, and bird feeders from unwanted cats with the STV Mega Sonic Cat Repeller (STV606), a motion-activated ultrasonic deterrent from the STV Defenders range. When a cat enters the protected zone, a built-in PIR sensor triggers a continuously variable sonic burst that cats find uncomfortable but humans cannot hear — keeping gardens feline-free without harm.

Ideal for placing near flower beds, vegetable patches, bird feeders, fish ponds, or sandpits where cats are a nuisance, this stake-mounted repeller pushes straight into soft ground for instant setup. The motion sensor detects movement up to 12 metres away in an 80° arc, providing a protected zone of up to 120 m² — enough to cover most domestic gardens and allotment beds.

Built for permanent outdoor use, the dual-casing design with internal rubber seals delivers IP44-rated water resistance, ensuring reliable year-round performance through UK rain, frost, and sun. Power comes from standard batteries for cable-free flexibility, or an optional 9V STV612 mains adaptor (sold separately) for set-and-forget installation.

How It Works

• PIR sensor detects movement: a built-in passive-infrared sensor scans the protected zone up to 12 metres away in an 80° arc.
• Sonic burst fires: when a cat (or other small animal) enters the zone, the unit emits a continuously variable ultrasonic burst that cats find uncomfortable but humans cannot hear.
• Cat moves away: the unpleasant sensation deters the cat from returning to the protected area without causing pain, injury, or lasting distress.

Frequently Asked Questions

Is the ultrasonic sound harmful to cats?
No. The Mega Sonic Cat Repeller uses a continuously variable ultrasonic burst that cats find uncomfortable, encouraging them to leave the area. It does not cause pain, injury, or lasting distress — it simply creates an unpleasant sensation that cats learn to avoid.

Will the sound bother my dog or other pets?
The ultrasonic frequency is targeted at the hearing range of cats. Most dogs cannot detect it, and the sound is inaudible to humans. The unit is safe for use around households with dogs, birds, and other small pets.

How large an area does it cover?
The repeller detects motion and projects sound up to 12 metres in an 80° arc, providing a protected zone of up to 120 m² — enough for most domestic gardens, individual flower beds, or sections of an allotment.

Does it work in the rain?
Yes. The dual outer casing with internal rubber seals is rated to IP44, meaning it is splash-proof and protected from rain. It is designed for permanent year-round outdoor use in typical UK weather conditions.

How is it powered?
The repeller runs on standard batteries for completely cable-free use, or can be connected to mains power using the STV 9V Universal Mains Adaptor (STV612), which is sold separately. Battery life depends on how often the PIR sensor is triggered.

How do I install it?
Push the in-built ground stake firmly into soft soil at the edge of the area you want to protect, ensuring the PIR sensor faces the direction cats typically approach from. For hard surfaces, the unit can also be wall-mounted.
