I have spent a fortune on every kind of mouse trap I could find, and while they work for a couple of days the mice catch on to them right away. And then, the fancy and regular mouse traps stop working, because the mice get smart to them and don’t go in there. However, it would appear that these things actually work, and more than that, they actually have been effective in deterring what we call “piss ants” that nothing seems to get rid of. Now, we did get warmer weather. And there is the possibility that the mice decided to go outside cause it was warmer. So I can’t be 100% ssure that it was these electronic deterrent that worked. But it sure seems to me that it’s the first thing that actually has made a difference. I guess we won’t really know until winter time when we see whether mice return. But at the moment these things seem to be the first thing that actually works on a long-term basis.

I was freaking out because for the first time ever I had mice in my kitchen, ants must’ve found their way in through the same place. I placed one in the kitchen one in the basement and one in my bathroom. I have not seen a single pest in over a month. If you are a person who is scared of spiders that seems like the only pest that does not seem to be affected. I cannot hear any sound from this except for the clicking of the LED. If you are more than a couple feet away that is not an issue.

I have toyed with the idea of ultrasonic pest repellers for decades now, yes - decades. None of them over the years have worked. I just moved back into my old house after a complete renovation and we've just been fighting the never ending problem with ants. In the kitchen (of course), in the bathroom (weird, but ok), in the shower (weirder), in the laundry room, in the hall way, in the bedrooms... ok... in every room. You can't sit or stand anywhere for more than 2 minutes before you realize something crawled up your leg or already on your neck.My parents lived there for many years and complained about ants, but since I didn't live there for many years, I didn't understand how big of a problem it was. Even the contractors complained about the massive amount of ants in the house.Well, I decided to bring back one of my old ultrasonic repellers. I plugged it in for a couple days and - the ants were still there. I took it outside, where there are a swarm of ants. Plugged it in for a couple days. The ultrasonic was/is deafening, high pitch but the ants hadn't even budged. Even my dog turned to it like, "what's that annoying thing?", but we still had ants.I bought these repellers because a reviewer actually mentioned "in 2 weeks" and another reviewer mentioned "in a couple days". Ok, this is some data you can use, not just "works great" and "didn't work for me". So I installed these (pack of 3, just to try at first) in the kitchen and in 2 of the bedrooms. The next day, yes, I still had ants, however a lot less. And yes, day 2, I basically had zero ants an any of the rooms I installed these units in. I say basically because I still have ants on the other side of the kitchen, behind the fridge. I think the ultrasonic wave is not able to get there so I will find a way to install another unit near the fridge. I did order another pack of 3, which I will install in the other rooms and fridge.These units work! It took 2 days to work.Now to comment on the physical unit itself. Yes, these things are chunky and I was hoping I could find some that fit along side the light switches or electrical outlets for a cleaner install. Please let me know if anyone knows of one and one that works.It does make a ticking noise every few seconds. I think it is bursting ultrasonic waves instead of constantly flooding, like older units. It is annoying and another reviewer mentioned "you get use to it over time". Well, these have been working for about 2 weeks and I'm still not use to it, especially at night with all the lights off. All you hear is "tick... tick... tick... tick...". Is there any other way? I don't know if ants respond to higher frequencies and maybe the ticking will go away, but I wouldn't know.Anyway, without the "clean look", I would highly recommend these units, especially for ants. I still have spiders hanging around so, no, they don't appear to work on spiders. Also, placement seems to be really important as well as giving it a couple days, since ants to travel on a trail, so even if the immediate ants respond to the product, the ants further down the trail won't know what will hit them just yet.

DOES NOT WORK!Watched a flying mosquito-like insect fly right by it towards my bed.Not sure where package is so it would be hard to return - but I should have known better!!!!

These work wonderful. I have not had one ant in my house for a very long time. I am so glad Amazon carries this name brand because that is all I’ve ever used.

I have used this product for roughly a year. They do not seem to deter ants at all! It has no great effect beyond 3 ft on Spiders, bats, squirrels and voles.It does work on mice and rats very well and I will actually buy more to cover other structures. It seems like you need it at least in each corner of the house. It also does not seem to disturb the dogs.

This product was not working for me, thank you very much for your help and time with this matter.😢😢😩

They are seeming like they are starting to work. I put my in maybe a month ago, and I didn't start working anywhere from 2-4 weeks. So be patient with them! They might not work though if your house isn't clean. They go by sound waves, and when your house is a mess, then it could bounce of those objects causing them not to work. I put 1 in every single room, 2 if the room is bigger like my bedroom & living room. Also make sure your not putting them behind anything such as furniture and other soild objects because then the sound wave won't be able to project into the house. These aren't something that need to be replaced often, I think I read maybe every 5 or 10 years or something like that. If your in an area that is high in pests, then you may wanna double up I'm each room if you don't notice a difference after 4 weeks. I was pretty skeptical of this product at first, but decided to give it a try. We have spiders as do pretty much every house, stink bugs, boxelder bugs and ants. But after a month, I haven't noticed any of that around anymore. I think it's worth the money in my own opinion. I did give it a 5 star but I do hate the fact that the red light stays blinking all the time, but however, you do get use to it though! But if it weren't for the red light always blinking, then u wouldn't know if the device ever stopped working until the bugs started coming back, which obviously you would want to buy new ones before the bugs start to come back. I hope this helps anyone who is considering buying these.
