Ultrasonic Rodent Repeller VIANO model 281 for Rats, Mice and Martens

VIANO 281 is an ultrasonic rodent repeller designed to deter rats, mice and martens without poisons or traps. The compact plug-in device emits high-frequency sound pulses intended to create an uncomfortable environment for small mammals in indoor spaces such as homes, garages, attics and storage areas. The chemical-free design provides a non-lethal option to reduce rodent activity while allowing humans and pets to occupy treated rooms.

Advantages

The device operates by producing ultrasonic pulses that are difficult for rodents to tolerate while remaining inaudible or unobtrusive to most humans. Its plug-in format makes installation simple and immediate, with no need for direct contact with animals or the use of baits and poisons. The compact housing allows placement in narrow outlets and close to likely rodent access points, and the repeller requires minimal maintenance during operation.

Suitable for

• Homes and apartments — kitchens, basements and attics
• Garages and workshops
• Storage rooms and sheds
• Commercial backrooms and retail storage areas

Key specifications

• Target pests: rats, mice and martens
• Operating principle: ultrasonic high-frequency pulses
• Installation: plug-in, indoor use
• Coverage: suitable for single-room areas (coverage varies with room layout and obstacles)
• Power source: mains-powered plug
• Design: compact housing for wall outlet installation

How to use

Plug the unit into an indoor power outlet in the area where rodent activity has been observed, preferably elevated and unobstructed by furniture or curtains for better sound propagation. For best results, position the repeller near entry points, food sources or nesting areas. Leave the device continuously powered; ultrasonic repellers are most effective when operating over extended periods to encourage rodents to relocate. Periodically inspect the unit to ensure it remains plugged in and unobstructed.

Usage recommendations

For optimal performance combine the ultrasonic repeller with good hygiene and exclusion measures: seal cracks and holes, store food in rodent-proof containers, remove clutter and block access to nesting materials. Avoid placing heavy objects in front of the device or using it behind thick walls, as solid barriers reduce ultrasonic effectiveness.
