Ultrasonic Pest Repeller Plug Set

Velleora Home Decor's Ultrasonic Pest Control Plug Set comes as a multi-pack for a practical reason: ultrasound does not travel through walls, so one unit only ever treats the room it is plugged into. A set lets you cover a kitchen, a utility, a loft hatch landing and a garage at the same time.

Each unit plugs into a standard socket and emits pulses above the range of normal human hearing, intended to make a room less comfortable for insects and rodents. There is nothing to refill, no bait to place, no chemicals on food surfaces and no smell. Power draw is tiny, so they can be left running continuously, and an indicator light on each confirms it is working.

Set expectations realistically: results vary a great deal between homes, and a plug-in device is a deterrent that may reduce activity rather than a guaranteed fix. Use an open socket rather than one hidden behind furniture, keep one per problem room, and call a professional for an established infestation. Do not use ultrasonic devices in rooms housing hamsters, gerbils, rabbits or other small pets.
