Ultrasonic Pest Repeller 4 Packs,Electronic Plug in Sonic Repellent pest Control for Mosquitoes Roaches Ant Mice Bugs Rodents Insects Mouse Spiders

At first I didn’t think this pest control device was making a difference, but I notice there were no little bugs...all gone. When you open your door to get in and out you expect something to fly in with you...Somehow they disappear...I’m not sure where the bugs are going but it must be working it’s magic. You really don’t remember it’s there.

I live in a older house that has small where the floor meets the wall in a couple of places, mainly near crawl space locations. Some of the gaps are large, so fixing them is going to costs a small fortune. For the first time in 10 years, I've had a single rat move into my house. I bought a pack of these repellers hoping they would fix the problem, but the rat doesn't seem to mind them at all. I even have 2 installed in one room. They just don't work. I'm now looking at other options such as a more expensive device. I've had field mice problems over the years, and never had that much trouble trapping them. But rats are a totally different animal. They are 10x smarter than a mouse. They won't mess with a trap if it's new to the environment. I don't wan't to use poisen because they could be living in the walls and I dont' want to risk them dying and me not being able to get to the carcus. I'm very disappointed in this purchase. I highly recommend you go with something else for rats or mice.

Ordered these last year for an ant problem within weeks along with some other ant bait traps they worked great haven't seen bugs in months up until a few weeks ago I noticed the lights were all almost burnt out on them so decided to order new ones. First shipment I received 2/4 worked the other 2 were defective wouldn't light up so I gave it another shot because they worked great in the past. Today I received my 2nd replacement and received 2 that fully light up then the other 2 are halfway lit up as if they been used. Also 2 of the plug ins have a logo the other 2 do not. So if you're a gambler and think you'll receive 4 fully effective ones I'd highly recommend these but having received 2 orders in one week both being defective is what's making me give 3 stars i would be giving 5/5 if I received the same exact product i received last year as it worked amazing. Peep the 2 photos which came out the same box today

The apartment below has holes under their kitchen sink and mice got into my place and were having a huge party under my sofa and all over my kitchen. I could hear them at night. So gross. I have since sanitized my apartment and left three of these devices plugged in my 500 sqft apartment. The first night after I plugged them in I heard mice scream and after the second night I found two baby mice bodies on my kitchen floor between two units that faced each other. I think these are meant to be a deterrent but in this case because I had so many plugged into such a small space and the mice were young, I think it may have killed them. So far so good. No mice have returned and it's been five days since I plugged these in. I recommend people try this.

somehow we got a rat in the wall of our bedroom and we could hear it at night going back and forth, I went up into the attic to see if by chance it was going up there so I could put some traps up there (nope). I was able to find where it was getting in, but without getting it out first I was not going to close up the hole and then have to deal with a stinky rat in the wall. Not really having a lot of options, I decided to take a gamble on this, I have always thought these devices were just a gimmick and a scam, but we didn't really have many options besides opening up part of the wall and putting a trap in. The first night we plugged it in, there was all kinds of commotion going on in there, it almost sounded like a bird was trapped in there. after about a hour the noises stopped and we haven't heard any more since then. I am COMPLETELY blown away that this even remotely worked let alone worked as well as it did. I still cant believe that it worked.

Satisfied with these repellents, because they actually look good and non-invasive, and more importantly, they seem to take four weeks to work, because they need small vermin to pack boxes and collect everything, but so far, it's quiet to get past it and keep it that way. We bought the product after finding our mouse under the sink area of the kitchen. Since I started using plug-ins, no mouse has been in the room for four weeks. When the weather is good, my back door is still open, and flies, spiders, etc. enter the room. The service is very good. I like weird email. So, thank you, thank you for relieving my loft pressure. Definitely recommended. I'm really glad... It's highly recommended to use this device

I like is a old farm house so I know I have mice. But I always hoped the stayed down in the basement. When I saw one in the living room I went on and order these along with mouse traps.I plugged these and didn't see anything for about 6 weeks. The traps I set also didn't catch anything. And, then about 6 weeks later I mouse scurried across my living room, right in front of the device. I set out a few more mouse traps and with in 3 days I caught 3 mice. It does say that on weeks 5-6 the mice find the noise intolerable and flee. So maybe that is what is happening and they just can't find there way other. But, the reviews looked so promising.If anyone is wondering I have 5 on my first floor and 3 on my second floor.I'll keep them plugged in and update this review as needed. But currently I am pretty disappointed and super tired of deposing of Mouse Corpses.
