WHILE OTHER BAT REPELLENTS are not pet friendly, don't really work, and have unpleasant odors, the Pest Destruct Ultra Bat Repellent operates silently, is odorless, effectively repels bats, and is safe for children and pets. HOW IT WORKS – This ultra bat repellent uses biological principles by emitting ultra waves that deter bats and other unwanted pests, encouraging them to leave the area naturally. There are no dead pests to remove from your home. One unit covers an area of 60–80 sq ft. ENJOY LIVING IN A PEST-FREE HOME – While specifically designed to repel bats, this ultra device is also effective against mice, rats, flies, bugs, mosquitoes, fleas, and cockroaches.
