Bell+Howell Ultrasonic Pest Repeller User Manual
Model: 50127
Introduction
The Bell+Howell Ultrasonic Pest Repeller is designed to help control various pests in your home using advanced ultrasonic technology. This device emits high-frequency sound waves that are irritating to pests but generally undetectable by humans and most household pets. It offers a chemical-free and odor-free solution for pest management.
Product Features
- Safe for Pets and Kids: Operates without harmful chemicals or odors, making it safe for use around children and pets.
- Easy to Use: Simply plug into a standard electrical outlet.
- Effective on Most Rodents and Insects: Designed to repel mice, rats, spiders, ants, roaches, and other common household pests.
- Ultrasonic and Variable Technology: Emits constantly changing wavelengths to prevent pests from adapting to the sound.
- Silent and Odorless Operation: Provides pest control without noise or chemical smells.
- Room Coverage: Each unit is effective for a single room, as ultrasonic waves do not travel through walls. For optimal performance, use one repeller per room.
- LED Indicator: A built-in LED light indicates that the unit is powered on and operating.
- Multiple Sizes: Available in Classic, Micro, and Extra Outlet designs to suit various placement needs.
Setup and Installation
- Unpack: Carefully remove the pest repeller units from their packaging.
- Placement:
- Identify areas with pest activity or potential entry points.
- Place one unit per room for maximum effectiveness, as ultrasonic waves do not penetrate walls or solid objects.
- Ensure the unit is not obstructed by furniture, curtains, or other large items that could block the ultrasonic waves.
- For best results, plug the unit into a lower outlet, close to the floor, as most pests travel along the floor.
- Power On: Plug the unit directly into a standard 120V AC electrical outlet. The LED indicator light on the front of the unit will illuminate, confirming it is powered on and emitting ultrasonic waves.
- Initial Period: Allow 2-4 weeks for the device to achieve full effectiveness. Pest activity may initially increase as pests are driven out of their hiding places.

- No adjustments or settings are required after initial plug-in.
- For continuous protection, keep the units plugged in at all times.
