While other bat repellents may not be pet-friendly, are ineffective, or have unpleasant odors, Pest Destruct Ultra Bat Repellent operates silently, is odorless, and is safe for use around children and pets. This device uses ultra technology to deter bats and other unwanted pests by emitting high-frequency sound waves that are in ble to humans. It effectively covers areas from 100 to 800 square feet, depending on the layout and obstacles in the space. Designed for indoor use, it helps keep homes free from bats, mice, rats, flies, insects, mosquitoes, fleas, and cockroaches. The unit requires no messy cleanup of pests and functions without producing any harmful residues. **Product Specifications:** - Voltage: 100-240V AC, 50/60Hz - Power: 2.5W - Output frequency: 20-65 kHz **Installation Guidelines:** Plug into indoor electrical outlets only. Avoid outdoor use or placement in hot, wet, humid, or liquid-prone environments. For optimal performance, ensure there are no obstructions directly in front of the unit that may block ultra wave dispersion.
