Setting up your Bell+Howell Ultrasonic Pest Repeller is straightforward:
- Unpack the device from its packaging.
- Plug the repeller directly into a standard 110V 2-prong electrical outlet.
- Ensure the red LED indicator light illuminates, confirming the device is powered on and functioning.

5. Operating Instructions
The Bell+Howell Ultrasonic Pest Repeller utilizes intelligent variable technology to emit ultrasonic frequencies. These frequencies are constantly changing to prevent pests from becoming accustomed to the sound, ensuring continuous effectiveness.
- The device operates silently to humans and most pets.
- The red LED indicator light confirms that the ultrasonic waves are being emitted.
6. Placement Guidelines
For optimal effectiveness, consider the following placement guidelines:
- Plug the device into an outlet that is approximately 36 to 48 inches (91 to 122 cm) off the floor. This height helps ensure the ultrasonic waves can travel effectively without being absorbed by furniture or other objects.
- Place one unit per room or open floor plan area. For larger spaces or areas with many obstructions, additional units may be beneficial.
- Avoid placing the unit behind large furniture, curtains, or other soft materials that can absorb the ultrasonic waves.
- Allow 2 to 3 weeks for the device to achieve its full effect in repelling pests. Consistent use is key.
7. Maintenance
The Bell+Howell Ultrasonic Pest Repeller requires minimal maintenance:
- The device is designed for continuous operation and does not require chemical refills or regular upkeep.
- Periodically check that the LED indicator light is on to confirm the unit is functioning.
- Keep the device clean by wiping it with a dry cloth if dust accumulates. Do not use liquid cleaners.
8. Troubleshooting
If you encounter issues with your pest repeller, consider the following:
- No LED Light: Check if the device is securely plugged into a working electrical outlet. Try plugging it into a different outlet to rule out a power issue.
- Pests Still Present: Remember that it can take 2 to 3 weeks for the device to achieve full effectiveness. Ensure the unit is placed optimally, not obstructed by furniture or soft materials. For severe infestations, additional pest control methods may be necessary initially.
- Reduced Effectiveness: Ensure the device is not blocked and that the area is not too large for a single unit. Consider adding more units for broader coverage.
