While other bat repellents aren't pet-friendly, don't really work, and smell bad, the Pest Destruct Ultrasonic Bat Repellent is silent to the human ear, has no odor, eliminates bats perfectly, and is 100% safe for children and pets. HOW IT WORKS - This ultrasonic bat repellent works on a biological level by emitting ultrasonic waves to send bats and other unwanted guests back to nature. This means you don't have to remove dead bats, mice, rats, flies, or beetles from your home. One unit covers an area of 100-800 square feet. ENJOY LIFE IN A PEST-FREE HOME - While this ultrasonic repellent is specifically designed to eliminate bats, it also works on mice, rats, flies, beetles, mosquitoes, fleas, and cockroaches.
