Weitech Pest Repeller Ultrasonic Professional

•Ultrasonic sounds do not pass through walls, doors, furniture, etc.
•Do not place behind curtains, sofas or other furniture which may block the sound emission.
•Use at least 1 unit in each room to be protected
•Rooms furnished with lots of textiles (curtains, drapes, upholstered furniture…..) require a more powerful unit because ultrasonic sounds are absorbed by soft materials.
•For increased effectiveness, it is preferable to use 2 smaller units installed in different parts of the room rather than 1 large pest repel product.
