Big Cheese Anti Mouse Mini-Sonic Mouse Repellent 3 pack

Use one repellent device per room. Keep the device switched on whilst controlling an infestation, or use it as a preventative against the return of rodents.

The unit releases ultrasonic sound waves which only rodents can hear.

The sounds cannot be heard by humans or other non-rodent pets, and create an acoustically hostile environment, causing the rodents to move away and find an alternative habitat.

It shouldn#t be used around rodent pets such as gerbils, hamsters and guinea pigs as the sound will be within their hearing range.
