It utilizes fine-tuned low-frequency waves to create a deterrent environment that feels much cleaner than traditional traps.

The Bell + Howell Ultrasonic Pest Repeller Home Kit offers a chemical-free way to reclaim your living space from uninvited guests. Instead of dealing with messy traps or pungent sprays, this six-pack uses variable ultrasonic frequency waves to irritate rodents and insects until they leave for good.
