Buying Guide
What should you consider when choosing a rodent plug-in repellent?
- Room size and layout: Larger homes often need multiple units placed in open spaces to maximize coverage.
- Target pests: Some models emphasize rodents, others focus on insects like ants, roaches, or mosquitoes. Choose based on the main problem in your space.
- Number of devices: If you have a sizable floor plan, a multi-pack offers better per-room coverage and redundancy.
- Noise and pets: Most devices are designed to be pet-safe, but some modes can emit audible sounds. Use appropriate modes when rooms are unoccupied.
- Installation: Look for plug-in units that are easy to place away from obstructions and near the center of rooms for balanced coverage.
- Maintenance: Ultrasonic devices typically require no chemicals or batteries, but ensure vents are clear and outlets are not overloaded.
How to maximize effectiveness
- Place one unit per room or open area, especially in high-traffic zones like living rooms, kitchens, and garages.
- Avoid placing units behind furniture or inside cabinets where signals can be blocked.
- Start with the default mode, then adjust based on pest activity and household presence.
