When the cold weather arrives, rats and mice head for the warmth - and your house could be the next target. Here is the inspector's checklist to help you seal, clean and protect your home before winter hits.
Autumn - the peak season for rodents
Every year during September and October, the number of infestations increases dramatically. As nature's larder is depleted of food, rodents seek shelter - and your home becomes the next target.
- Many people think that rat problems occur mostly in big cities, but the fact is that almost all homeowners are affected sooner or later. And autumn is the critical time when they establish themselves, says Örjan Johansson, researcher at Luleå University of Technology.
Why conventional methods are not enough
Cleaning, sealing and clearing around the house is a good start - but it is rarely enough. Mice can squeeze through gaps of just 6 millimetres. And once inside, they are extremely difficult to get rid of.
Many homeowners then turn to simple ultrasonic scarers sold cheaply online. But there is a pitfall here:
-
Most models only emit a solid tone in one corner of the room.
-
Rodents often get used to the sound - the effect wears off after a few weeks.
- This is why so many people are disappointed. They buy a cheap scare, but the mice come back," says Örjan.
Why Repello works - when others fail
Repello was developed in collaboration with researchers at Luleå University of Technology, and the technology has also been evaluated by SLU (Swedish University of Agricultural Sciences). Studies show that rats react instinctively - they do not perceive the sound as a disturbing noise, but as a real warning from their own conspecifics.
This makes the technology sustainable over time. They won't come back, because their instinct tells them the place is dangerous.
The result is a home that feels uninhabitable to rodents - without the need for poisons, traps or chemicals.
- Without Repello, it is almost impossible to fully rat-proof a house. "Now is the time to act - if you wait until they've already moved in, it's too late," says Örjan.

It's as simple as that
-
Plug Repello into a standard wall socket.
-
Leave it switched on around the clock.
-
After just a few hours, you can see the difference - the rodents disappear.
Customers' experiences
Thousands of Swedish homeowners already use Repello. Many testify that they tried everything before - sealing strips, traps, scents and cheap ultrasound - but nothing worked until they installed Repello.
- We hear from customers all the time who say: "This was the first winter without mice in the house". That's the kind of peace of mind Repello is designed to provide," says Örjan Johansson.
