1. Product Overview
The Bell and Howell Ultrasonic Pest Repeller is designed to help deter various pests such as mice, rats, spiders, ants, mosquitoes, and cockroaches from your home or office. This device operates by emitting ultrasonic frequencies that are irritating to pests but are generally inaudible to humans and most household pets. It offers a chemical-free, odor-free, and sound-free solution for pest management.
The complete kit includes multiple units of varying sizes to provide comprehensive coverage for different areas within your living space.
2. Features

- Broad Pest Deterrence: Helps to repel a wide range of pests including mice, rats, spiders, ants, mosquitoes, and cockroaches.
- Ultrasonic Technology: Utilizes a mix of highly-effective ultrasonic frequencies to create an uncomfortable environment for pests, encouraging them to leave the area.

3. Setup Guide
Setting up your Bell and Howell Ultrasonic Pest Repeller is straightforward:
- Unpack the Devices: Carefully remove all repeller units from their packaging.
- Choose Placement: Select an appropriate electrical outlet for each unit. For optimal effectiveness, place one unit per room where pest activity is observed or anticipated. Ensure the unit is not obstructed by furniture, curtains, or other objects that could block the ultrasonic waves.
- Plug In: Insert the repeller firmly into a standard 110V-120V AC electrical outlet.
- Verify Operation: Once plugged in, the LED indicator light on the front of the unit should illuminate, confirming that the device is powered on and functioning.
Note: For best results, it is recommended to use one repeller per room. The ultrasonic waves do not penetrate walls or solid objects effectively.

4. Operating Instructions
The Bell and Howell Ultrasonic Pest Repeller operates continuously once plugged into an active electrical outlet. There are no buttons or settings to adjust.
- Continuous Operation: For best results, keep the repeller plugged in at all times. The device emits ultrasonic waves constantly to create an unwelcoming environment for pests.
- LED Indicator: The red LED light on the front of the unit indicates that the device is powered on and actively emitting ultrasonic frequencies. If the light is off, check the power outlet.
- Initial Results: It may take several days to a few weeks to notice a significant reduction in pest activity. Pests may initially appear more active as they are driven out of their hiding places.
- Coverage Area: Each unit is designed to cover a single room. For larger areas or multi-room homes, use multiple units as provided in the kit.

5. Maintenance
The Bell and Howell Ultrasonic Pest Repeller requires minimal maintenance:
- Cleaning: If necessary, gently wipe the exterior of the unit with a dry, soft cloth. Do not use water, cleaning solutions, or abrasive materials.
- Obstruction-Free: Periodically check that the front of the unit, where the ultrasonic waves are emitted, remains unobstructed by furniture, curtains, or other household items.
- No Consumables: The device does not require refills, batteries, or any other consumables.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LED indicator light is off. | No power to the outlet, or unit is faulty. | Check if the outlet is working by plugging in another device. Try plugging the repeller into a different outlet. If the light remains off, the unit may be faulty. |
| Pest activity persists or increases. | Initial increase in activity is normal; unit is obstructed; unit is too far from pest entry points; pest type is not affected by ultrasonic waves. | Allow 2-4 weeks for full effectiveness. Ensure the unit is not obstructed. Place units closer to known pest entry points or areas of activity. Consider if the specific pest type is known to be affected by ultrasonic repellers. |
| Unit makes a faint noise. | This is normal operation. | Some individuals with sensitive hearing or pets may detect a very faint high-frequency sound. This is part of the normal operation and indicates the unit is working. |
