One unit covers approximately 40 m². For best results, we recommend one unit per floor level or per separate space, such as a basement, garage, or storage room.

In tests against competitors, Repello has up to 30% higher sound levels, causing rodents to flee immediately. Thanks to the unique sound sequences, rats don't get used to the sound – and therefore won't come back.

Yes! Repello is designed to affect both rats and mice. The product uses their own alarm signals – sounds that both species are biologically programmed to react to.

So you don't need different models – one and the same Repello works effectively against both types of rodents.

No. Repello is based on signals that activate the rat's ancient flight instinct. It's not a sound they can learn to ignore – the brain reacts reflexively.

Repello is designed for indoor use, where the sound spreads and reflects between walls for maximum effect. Outdoors, the sound dissipates more quickly, so the effect is limited there.

Yes, Repello works against both rats and mice, including wood mice. It disrupts their natural alarm signals, causing them to leave the area and avoid returning.

No. The sound is inaudible to humans, dogs, and cats. Repello is is completely safe to use in homes, restaurants, and other environments where people and pets are present.

Yes. Repello was developed in collaboration with researchers.

A pilot study conducted by the Swedish University of Agricultural Sciences (SLU) showed promising results, with rat presence decreasing dramatically. The results showed a significant reduction in rat observations, with activity dropping by over 91%.

At present, Repello is only available for mains-powered operation, as the technology requires a steady and stable power supply to deliver full effect.

Yes, Repello can be used in motorhomes as long as there's access to a mains socket (220V). Many people use it during winter storage to prevent mice and other rodents from getting in.

Yes, Repello can be used in the car – especially during winter storage or when the car is parked for longer periods. The product plugs into a standard mains socket (220V), so if you're able to connect the car to electricity (e.g. via an engine heater socket or in a garage), it works well.

No, Repello is very energy-efficient and only consumes about 2.8 watts, which is roughly the same energy consumption as a small night light. You can therefore leave it plugged in around the clock without it having any noticeable effect on your electricity bill.

The sound from Repello spreads best in open spaces, where it can be reflected off walls and floors. The sound doesn't travel effectively through solid materials such as walls, ceilings, or insulation – so the unit is recommended in the room or space where the problem is.

Plug Repello into the wall socket and place it low near the floor, where rats and mice move around. Avoid placing it behind furniture, curtains, or other objects that could block the sound – it should stand free for the best distribution.

The unit works best in the room or space where you notice activity, such as in a basement, crawl space, storage room, or garage.
