Product information
Repello is the world's first mouse repeller based on scientifically documented alarm signals. Unlike ordinary ultrasonic devices, which mice quickly get used to, Repello is based on a unique sound pattern that activates the rat's ancient flight instinct.
- Patented technology – developed at Luleå University of Technology (LTU) and the Swedish University of Agricultural Sciences (SLU).
- Up to 30 times stronger sound
Repello uses a unique sound chamber that amplifies the signals up to 30 times more than conventional ultrasonic devices. - Works against both rats and mice – documented effect on several species
Installation and use
Easy installation
The Repello mouse repeller is designed to be used straight out of the box. Simply plug the device into a wall outlet in the area you want to protect, for example in the attic, basement, or a storage room. Place it as unobstructed as possible so the sound signals spread evenly throughout the room.
Place a mouse repeller in each risk area:
- Kitchen – scares away mice searching for food scraps and waste.
- Garage – prevents mice from nesting among boxes and vehicles.
- Crawl space – place near the entrance where rats often enter.
- Basement and attic – typical habitats for mice; install a device if there is an electrical outlet.
- Storage rooms and warehouses – protects food, feed, and materials from rodents.
- Laundry room or boiler room – places with water pipes and heat that attract rats.
How it works
When the device is activated, a unique sound signal is emitted, developed by researchers at Luleå University of Technology (LTU) and the Swedish University of Agricultural Sciences (SLU). The signals are based on documented research and trigger the mice's primitive flight instinct.
To mice, the sound is perceived as an acute threat, causing them to leave the area shortly and avoid returning. The effect is documented in several tests where up to 100% of the mice disappeared within 24 hours.
Maintenance-free
The product requires no maintenance or supervision. Once the device is plugged in, it operates completely automatically.

What is a mouse repeller – and why do you need one?
Mice are a growing problem in Swedish homes. They get in through the smallest cracks, gnaw on electrical wires, destroy insulation, and leave behind unhygienic traces. In addition to the damage, mice can also spread diseases. The use of poison is increasingly questioned, both because of environmental risks and because legislation restricts its use. Therefore, many homeowners, farmers, and businesses are looking for new solutions – and this is where mouse repellents come into play.
A mouse repellent is an electronic device that emits sound frequencies or vibrations that make mice avoid the area. But far from all products on the market work equally well. Most cheap variants are based on simple ultrasonic technology – something that mice quickly learn to ignore.
Why ordinary mouse repellents are not enough
There are plenty of mouse repellers to buy online or in stores, but independent tests often show a weak effect. The reason is simple: the devices usually emit a constant tone. For us humans, it is inaudible, but for the mice, it soon becomes part of the background noise. And since mice are quick to adapt, the sound loses its deterrent effect.
Many homeowners have reported how they bought these repellers hoping for a solution, only to find that the mice are back after a few days. Therefore, many of these products are described as pure scams. This is where the research behind Repello Mouse repeller makes a difference.
Swedish research shows the way
Repello is the result of several years of research at Luleå University of Technology (LTU) in collaboration with Swedish University of Agricultural Sciences (SLU). Professor Örjan Johansson and his research team studied exactly how different sound frequencies affect the nervous system of mice.
Through careful laboratory tests, the researchers were able to identify sound sequences that activate the so-called reptilian brain – the part of the brain that controls the animals' most primitive reflexes for flight and survival.
Frequently Asked Questions
Does Repello really work – has it been tested?
Yes. Repello is the result of several years of research at Luleå University of Technology (LTU) and the Swedish University of Agricultural Sciences (SLU). In controlled tests, up to 100% of the rats disappeared within 24 hours and avoided the area for up to 18 days, even when the sound was turned off.
Can humans or pets hear the sound?
No. The sound is inaudible to humans, dogs, and cats. Repello is completely safe to use in homes, restaurants, and other environments where people and pets are present.
How large an area does a Repello unit cover?
One unit covers approximately 60 m². For best results, we recommend one unit per floor or per separate space, such as basement, garage, or storage room.
Is Repello dangerous for other animals?
No. Repello is specifically aimed at rats and mice. The sound profile is adapted to their hearing and is not perceived by humans or most other animals.
How quickly does one notice an effect?
Most rats leave the area within a few minutes after activation. In some cases, it can take up to 24 hours before all are gone.
Can the rats get used to the sound?
No. Repello is based on signals that activate the rat's ancient flight instinct. It is not a sound they can learn to ignore – the brain reacts reflexively.
Does it work against mice?
Yes, Repello also works against mice, including field mice. The product is designed to disturb both rats and mice through their natural alarm signals, so they leave the area and avoid coming back.
