While other bat repellents may not be pet friendly, have unpleasant odors, or limited effectiveness, Pest Destruct Ultra Bat Repellent operates silently, is odor-free, and is safe for use around children and pets. How it works – This ultra device emits sound waves that are designed to deter bats and other unwanted pests by creating an environment that encourages them to leave the area. It requires no cleanup of deceased animals and covers up to 800 square feet, depending on layout and obstructions. Enjoy a more comfortable living space – although primarily designed for bats, this repellent may also help deter mice, rats, flies, insects, mosquitoes, fleas, and cockroaches. We are committed to quality and safety, using our products in our own homes to ensure performance and reliability for your family. Product Specifications 1. Voltage: 100–240V AC, 50/60Hz 2.
