Indoor Plug (2-pack)

The tones sit above the range most people can hear, so the room should stay quiet to you. Some children and pets are more sensitive to high frequencies, which is worth keeping in mind if you have very young kids or small caged animals nearby.

Most cats and dogs are unaffected and settle in normally around the unit. Small caged pets like hamsters, mice, and rabbits are in the same hearing range as the pests it targets, so keep units out of the rooms where those animals live.

No. This is a plug-in, mains-powered unit. It runs continuously from a standard wall outlet, so there is nothing to charge and no batteries to replace.

Ultrasonic deterrents work gradually. Existing pests need time to decide the space no longer feels safe, so most customers notice activity easing over the first week. Keeping the unit on continuously gives the best results.

Ultrasonic sound is easily blocked by walls, doors, and large furniture, so treat each unit as covering one open room. For rooms that connect through a doorway, or for very cluttered spaces, place a unit in each area rather than relying on one to reach around corners.

Choose an outlet where the sound can travel across open floor toward where you see activity, rather than behind a couch or cabinet. Lower outlets near the baseboards where rodents travel tend to work well.

Honestly, they are a deterrent, not a cure. Independent testing shows mixed results, and ultrasonic sound alone rarely clears an established infestation. Where it helps is as one layer in a larger approach: pests often find the sound annoying and are less inclined to settle in an area, especially early on. Pair it with sealing gaps, removing food and water, and cleaning up clutter. If you already have a heavy, entrenched problem, treat the source first and use the repeller to help discourage pests from returning. Set realistic expectations and give it time in the right spot.

This is the key limitation to understand: ultrasonic sound does not travel through walls, doors, or furniture. It is highly directional and gets absorbed or blocked by solid objects, so each unit really only covers the open area of the room it is plugged into. That is why one device cannot protect a whole house. As for pests, results vary by species. Some people notice reduced rodent and insect activity, but there is no strong evidence it reliably drives out spiders or fully clears mice or roaches on its own. Use it per room, in open space, as part of a broader plan.

For cats and dogs, it is generally considered safe. The frequencies sit above comfortable human hearing, and while some dogs and cats can technically detect them, most simply habituate and treat it as background noise. The important exception is pet rodents. Hamsters, guinea pigs, rabbits, mice, rats, gerbils, and ferrets hear the same frequencies the device targets and can become stressed, so do not use it in rooms with those animals. Birds and fish are typically unaffected. If your pet seems agitated or you have any health concerns, unplug it and check with your veterinarian.

Plan for roughly one unit per room you want to cover, since sound will not pass through walls. Plug it into an open outlet a foot or two off the floor, not hidden behind furniture, curtains, or large appliances that would block the signal. Aim it toward the open area and known problem spots like along baseboards or near entry points. Garages, kitchens, basements, and attics are common placements. Leave it running continuously and give it a couple of weeks. For whole-property coverage, add units room by room or step up to a layered outdoor-plus-indoor setup.
