While other bat repellents may not be pet-friendly, have unpleasant odors, or lack effectiveness, Pest Destruct Ultrasonic Bat Repellent operates silently, is odorless, and is safe for use around children and pets. It uses ultrasonic technology to deter bats and other unwanted pests by emitting high-frequency sound waves that are inaudible to humans. How it works – This device emits ultrasonic waves that create an uncomfortable environment for bats, mice, rats, flies, insects, mosquitoes, fleas, and cockroaches, encouraging them to leave the area. It provides a humane solution without causing harm or leaving behind pests to clean up. One unit effectively covers areas from 100 to 800 square feet when placed in open spaces without obstructions. Enjoy a pest-free home – Designed primarily for bat deterrence, this repellent also helps repel a variety of common household pests. Product Specifications: 1. Voltage: 100-240V AC, 5060HZ 2.
