While other bat repellants are not pet friendly, don't really work and smell bad, Pest Destruct Ultrasonic Bat Repellent works silently on the human ear, has no odor, completely eliminates bats, and is 100% safe for children and pets. How it works - This ultrasonic bat repellent works on a biological level by sending out ultrasonic waves to send bats and other unwanted guests back to nature.

ENJOY LIFE IN A PEST-FREE HOME - While this ultrasonic repellent is designed to eliminate bats, it's also good for mice, rats, flies, bugs, mosquitoes, fleas, and cockroaches.
