For a cleaner, less intrusive way to take care of pests in your home, use Electronic All-Pest Repellers from Bird-X. These sound-based pest repellers keep away insects and small rodents without the use of chemicals or traps. Instead, they give off an ultrasonic sound wave that deters pests from getting too close. The frequency of the pest deterrent can't be heard by most humans, making it an annoyance to insects but not to you. Set it as a continuous sound to make sure pests always keep their distance, or use it as a motion-activated pest repeller that only triggers when pests get close. With six in this pack, you'll be set to take care of multiple parts of your home.
