Each set contains two ultrasonic repellers that together offer greater coverage than a single device. By using high-frequency sound waves, an unpleasant environment is created for rodents, causing them to avoid spaces and settle there less quickly.

The repellers operate with variable frequencies from 22 to 65 kHz, making it difficult for mice and rats to get used to the sound signal. Each repeller has a range of approximately 50 m², allowing the two devices together to effectively protect areas up to 100 m². This makes the set ideal for use in homes, offices, warehouses, supermarkets, bakeries, and hospitality venues.

The Ronada 2-Pack works completely without poison, traps, or chemical agents, making it a safe and maintenance-free solution for preventive rodent control. By strategically placing the two repellers, multiple rooms or larger areas can be effectively protected against unwanted mouse and rat infestations.
