OWLTRA OW-5 Ultrasonic Rodent Repellers 4 Pack, Effectively Repel Rodents While 100% Silent & Safe to Humans and Non-Rodent Pets, White

These mice are smarter than this product. Didn’t work at all

My husband and I live in a 1 bedroom 1 bath apartment. We have a mice problem, they travel through the vents. Not the smallest but not big. We have had all for plugged in for well over a month. We have changed areas put then closer together, spread out. We have tried everything. DO NOT BUY. THEY DO NOT WORK. And too expensive to just use for a night light. Odoban works better and it's only a disinfectant spray.

These little devices have been a game-changer for our home. We had some unwanted visitors in the garage and attic space, and within about one week of plugging these in, the activity completely stopped. I love that they're completely silent to us-no annoying buzzing sounds whatsoever. The built-in night light is a nice bonus, giving a soft glow while letting me know they're working. Setup couldn't be easier: just plug into any outlet. The 4-pack covered our whole main living area and garage perfectly. Such a simple, non-toxic solution that actually delivers results. Highly recommend for anyone dealing with pest issues!

You can certainly hear all 4 when they are plugged in. Might light is fine every where except the bedroom. Too bright. But no signs of mice since plugging them in. Even if the sound is annoying. 35 btw so I shouldn’t be able to hear the high pitched sounds.

I bought these and love that there is also a night light. I haven't seen any evidence of mice or insects at all. The cost is great too

My dog could hear this almost immediately and started acting scared and shaking. Unfortunately I’m 3 days outside the return window because they are completely useless.

I can't comment on the effectiveness. I do want to comment on the "silent" part. These aren't silent. If you know the sensation of being able to tell when a CRT tv is on even if it's not playing audio - this is similar. The first one I took out of the box happened to be much worse than the other 3. Maybe I'm hearing hum from the LED. Give me a quiet room. Plug this in. I'd hear it. I'm sensitive to high pitched noises, but I'm old and that sensitivity is fading. I imagine it would drive children crazy.
