Humans can hear sound frequencies up to 20,000 Hz. Sound above this frequency is called ""ultrasound"". Animals can hear ultrasound and find it so unpleasant that they do everything they can to escape from it. The Ultrasonic Rodent Repeller continuously transmits ultrasound waves that irritate mice, rats and martens. For the best result, leave the unit running constantly day and night.

Use the Repeller indoors only. Plug it into an electric socket in the room where rodent activity is suspected. The green LED lamp on the front of the unit will light up and the unit will ""hum"" softly. Place the unit on the floor, or on a low level surface with the speakers pointing towards the area of ​​rodent activity. Ensure that the path of the ultrasound is not obstructed by furniture or curtains. Each room requires at least one Repeller and that will cover up to 30 m². For a larger space, or an L-shaped room more than one device is needed.

1. Make sure that rodents have no access to food. Store food in sealed containers and keep kitchen and dining rooms clean.

2.Block all holes and openings through which rodents could come into the house. SWISSINNO ""Rodent Stop"" steel wool is perfect for this.

3. Reduce rodent populations with SWISSINNO mouse and rat traps.

The Ultrasound Rodent Repeller emits ultrasound frequencies from 22,000 to 30,000 Hz.

No, the Repeller emits ultrasound that does not penetrate walls.

Do not place the Repeller in rooms where rodent pets such as hamsters, mice, degus, guinea pigs, chinchillas, or the like are kept. Birds do not hear ultrasound so the Repeller does not affect them. Dogs and cats may get accustomed to the sound, or may avoid rooms where the Repeller is installed.
