Upgraded Ultrasonic Pest Control Repeller 6 Packs

I had my doubts, but after being bitten by a brown recluse, I immediately bought these. I was finding all sorts of dead flies that I didn’t know were in the home. So, super effective, doesn’t bother dogs, excellent value, no noise, safe, perfect size, and still working in August 2026, so very durable and long lasting.

I bought these because I had a mouse problem. I’ve noticed my scorpion problem is gone!! *knock on wood* I don’t even see the random dead scorpion around like I used to! I even have moved a few rocks outside and there was none under them either, which is usually where scorpions reside. It just took longer for them to work on mice, but it seems to have thinned them out, at least! I bought some easy set traps off Amazon and that’s been nice. I can set them myself and don’t have to ask hubby to do it for me because it takes a while for him to act. I’m scared of those old wooden traps, apparently he is too.

Useless, I’ve literally had ants crawling on it while plugged in. There’s another one plugged in by the door. Spiders crawl underneath. It doesn’t phase them. This thing is completely useless.

I've used similar products and honestly don't know exactly what to look for. When I purchased these I had began seeing tiny ants in a couple room throughout my business. I began using them the day that I received them and after a 10 day period I took the time to reassess. Searching high and low I wasn't able to see any evidence that I had an ant problem previously. It seems the effectiveness of this product is no joke. Who knows? Maybe the ants picked up and decided to move along to a different location, either way the timing coincided with the arrival of this product. It would be remiss of me to give the credit anywhere other than this product. Aside from the ants, the one off fly or bee situations have been fewer and fewer. I definitely recommend giving this product a try - especially with such a great price. Each unit seems well assembled and they do not emit any noise whatsoever.

Took about a month to notice that the flies and night time bugs no longer come in when the door is left open so it is working as it states.

I originally would give a one star and here is why: Okay I really wanted these to work and honestly thought they WERE working because we saw a down tick in mice/rats/shrews after initially using for several months on our farm. However now that it is winter in our area they are all back and these things don't seem to matter plugged in or not. So we are going to assume the cats had been taking care of them and now that it is cold, it appears everything is back and cats are doing less of good job on control lol. So while they were a good value, no noise level, they are NOT effective on mice, rats or shrews, especially if you live on a farm and they are prevalent. MAYBE they would be good in a small area or apartment that is NOT known to have a consistent flow of rodents. I am not sure. Good luck! I am changing my rating to a 2 because I contacted the company and they were so kind to initiate my warranty and provide a full refund WITHOUT us having to send the product back. For that we are sincerely thankful. We tried, just did not work for us unfortunately.

These bug repellers may work well - however I didn’t leave them in long enough to find out. They emanated a smell that was very overwhelming. I read the packaging to find out if this was normal but that issue wasn’t addressed. Instead I was told “not to worry” if I saw a an increased number of bugs running around the house as they would “be searching for a way to exit the house.” I certainly wasn’t wanting to see an increased number of bugs in my house since none had been visible in the first place. I bought these repellers as a preventative measure, not as a way to bring them out of hiding. That fact, plus the unpleasant odor, made me decide to NOT use them ever again.

I bought this 6-pack of ultrasonic pest repellers to cover multiple rooms in my home, and overall I’m pleased. Setup was super easy—just plug them in and the blue light shows they’re working. I like that they’re silent to me and safe around kids and pets (I have a cat, and she doesn’t seem bothered). After about 2–3 weeks, I noticed a real drop in hearing the sounds of mice and rats in my walls and ceiling around the kitchen and bathroom. I haven’t seen any mice either, which was my main concern. It doesn’t instantly clear pests—you have to give it some time—but once it kicks in, it seems effective. Overall, if you’re looking for a clean, non-toxic way to help keep pests away, this is a solid option. Just don’t expect a miracle in 24 hours.
