Repello Rat & Mouse Repeller

Repello is the world's first rat and mouse repeller with scientifically documented effect — developed with researchers at Luleå University of Technology (Sweden) and evaluated in a field study by the Swedish University of Agricultural Sciences (SLU). Instead of random ultrasound, Repello reproduces the rats' own alarm signal: the pulsed ultrasonic sweeps (25–85 kHz) that rodents use to warn each other of danger. The result: rats and mice perceive the room as unsafe and leave.

• Documented effect: over 90% fewer rat observations in the SLU field study — and 100% deterrent response from every rat exposed to the signal
• Patented, continuously shifting sound patterns — rodents cannot get used to it
• Completely silent to humans, dogs and cats — no poison, no traps, nothing to clean up
• Covers up to 40 m² of open space; one unit per room or enclosed area
• Piezo sound element in metal and ceramic — keeps full output for up to 20 years (ordinary membrane repellers fade after about 24 months)
• Plug-and-play: plugs straight into a 230 V socket (EU plug — fits Indonesian outlets). No buttons, nothing to configure

Ideal for hotels, villas, restaurants and homes: place one unit in each high-risk area — kitchen, food storage, roof space, garage or generator room. Ultrasound does not pass through walls, so use one unit per separate space.

Also known as: ultrasonic rat repellent, rodent deterrent, electronic mouse repeller, rat scarer. One device — it works on both rats and mice.
