This one does.

Rats and mice hate this sound (but you will never hear it)
Repello mimics warning signals that rodents use to alert each other to threats.
Rats and mice instinctively recognize it as a sign of immediate danger. They cannot ignore it – unlike ordinary ultrasonic repellents. Their instinct is to flee the moment it hits them.
These sounds are finely tuned to hit exactly the frequencies where rats and mice are most sensitive – yet still well above what humans can hear.
Repello emits in the red zone where rodents signal danger – but far beyond human hearing.
* Safe for cats, dogs, and birds. Do not use Repello if you have hamsters or other rodents as pets.

Don't waste money on cheap ultrasonic repellents.
Common ultrasonic repellents:
- Emit audible beeps that bother humans and pets.
- Use static wave patterns that pests get used to, so they come back.
- Produce weak signals that barely reach beyond one room.
Simple static ultrasonic beeping sounds
This is how Repello is better:
- Developed by researchers at LTU to be inaudible to humans.
- Changing sound patterns prevent pests from getting used to it.
- 10 times stronger signals penetrate deep into walls and hiding places.
Repello's waves mimic rats' warning signals
Gentle rodent control, discreet design
Developed in Sweden by researchers
Repello was developed by researchers at Luleå University of Technology (LTU) and the Swedish University of Agricultural Sciences (SLU).
Researchers studied how rats communicate to mimic their natural warning signals.
This makes Repello unique. Common ultrasonic repellents emit static beeping sounds that rats quickly get used to – and therefore come back.
Repello's signals cannot be ignored because they are rooted in the rodents' survival system.
The result: the rats disappear – and do not come back.
