4. Setup
4.1 Unpacking
- Carefully remove the OWLTRA OW-5 Ultrasonic Rodent Repellers from their packaging.
- Inspect each unit for any signs of damage. If any unit is damaged, do not use it and contact customer support.
4.2 Installation
- Identify areas with known or suspected rodent activity.
- Plug one repeller directly into a standard 120V AC wall outlet. Ensure the outlet is easily accessible and not obstructed by furniture or curtains.
- For optimal performance, position the repeller in an open area, away from solid objects like walls, furniture, or thick carpets, which can absorb or block the ultrasonic waves. The sound waves cannot penetrate solid surfaces.
- The built-in night light will illuminate, indicating the device is powered on and functioning.
- Use one repeller per medium-sized room where rodent activity is present. For larger areas or multiple rooms, deploy additional units as needed.

5. Operating Instructions
5.1 How It Works
The OWLTRA OW-5 repeller emits high-frequency ultrasonic sound waves that are specifically tuned to disrupt the nervous and auditory systems of rodents. These sound waves create an irritating and hostile environment for pests, causing them to avoid the treated area. This method is entirely physical and does not involve chemicals or traps.

5.2 Night Light Function
Each repeller includes a built-in night light. This light serves two purposes: it provides a soft illumination in dark areas and acts as a visual indicator that the device is powered on and actively emitting ultrasonic waves.

5.3 Best Practices for Effectiveness
- Consistent Use: Keep the repellers plugged in continuously for best results.
- Strategic Placement: Place units in rooms where rodent activity is observed. Ensure the ultrasonic waves have a clear path and are not blocked by furniture, walls, or other large objects.
- Initial Period: It may take 2 to 4 weeks to see a significant reduction in rodent activity as pests are gradually driven away. Patience is key during this period.
- Combine with Other Methods: For severe infestations, consider using the ultrasonic repellers in conjunction with traditional traps or baits for a more comprehensive approach during the initial phase.
- Eliminate Food Sources: Maintain good hygiene, store food in sealed containers, and promptly clean up spills to reduce attractants for rodents.
6. Maintenance
The OWLTRA OW-5 Ultrasonic Rodent Repellers require minimal maintenance to ensure continued performance.
- Cleaning: Unplug the device from the wall outlet. Use a soft, dry cloth to wipe the exterior of the repeller. Do not use liquid cleaners, sprays, or abrasive materials.
- Clear Obstructions: Periodically check that the repeller's speaker grille is not covered by dust, debris, or other objects, as this can impede the ultrasonic wave emission.
- Storage: If storing the device for an extended period, unplug it and keep it in a cool, dry place.
