1. Ultrasound does not penetrate walls. For maximum effectiveness, use one ultrasonic pest repeller per room. For larger areas, two devices may be necessary.

2. To prevent pests from escaping before they are sufficiently exposed to ultrasound, please close doors and windows in the area where the pest repeller is installed. This will ensure the product's effectiveness and prevent pests from returning.

3. Please allow 3-4 weeks for results. During the first few weeks, pest activity may initially increase as the ultrasound drives them out of their hiding places.

4. For maximum effectiveness, do not obstruct the pest repeller with large objects such as furniture (e.g., closets, sofas, chests of drawers).

5. To enhance effectiveness, it is essential to continuously use the pest repeller without interruption until the problem is resolved.
