Ultrasonic Pest Repeller 6 Pack,Upgraded Electronic Pest Repellent Plug in Indoor Pest Control for Insects, Mosquito, Mouse, Cockroaches, Rats, Bug, Spider, Ant, Human and Pet Safe

I can't recall ever being more impressed or pleased with a purchase than I am with these! We've had a TERRIBLE mice infestation for months. I mean you couldn't go 3 minutes without seeing one or two scamper across the floor, we've tried every trap or trick we could and they JUST KEPT COMING.I got these in the mail today, plugged them all up and we rushed off to my kid's Christmas program.. we were in such a hurry that I forgot to eat my burger before we left and I accidentally left it out on the kitchen counter (the mice favorite spot no matter how clean we keep it) When I got home and went to the kitchen, much to my surprise there wasnt a single bite taken out of it! I've now been home for about 5 hours and everyone is asleep (this is when the mice come out to play) and yet I havent seen or heard A SINGLE ONE!! We even got our first snow of the season tonight, it's been the coldest night so far, so that makes it even more impressive to me that I'm not seeing any mice! Also they havent bothered my dog one bit since I plugged them in! My husband thought these were a joke... but victory is mine muhahaha! Thank God and Amazon for no more mice! Hallelujah. Amen.**I'll update if anything changes, but if there is no update then you can assume I'm still happy as a clam with this purchase**

OK—these things do not work, like, at all. Full stop. They make decent night lights but I’m pretty sure that not only do they not work but they seem to attract the mice. Save your money and buy the sticky traps. I would return them for a refund, but honestly I’m too lazy. And my house is well-lit at night with blue light all around.UPDATE: Seller just contacted me to offer me $$ to remove the negative review. So PLEASE do not buy this product. What kind of retailer would ask you to remove a legitimate review and offer you money to do so? Amazon should do something about this but I cannot figure out how to contact Amazon directly about this.

I have always seen these and thought, "I doubt those work." Then I had to try them out because I've been having issues with mice in my apartment since I moved in about 4 months ago. I bought traps and within 2 weeks, caught about 15 mice. And they were getting into EVERYTHING! So I was a little desperate. Friend encouraged me to look into these at least and try them. So I did. And I have to say, I'm impressed. I have not seen one mouse in a week! If that changes at all, you better believe I will be updating this, lol. These are pretty easy to use. You just pull them out of the box and find a good spot in the room to place it. And just leave them be.

We got this to try, not expensive, for mice in a college dorm. That's a tough situation, many dorms and building volume for mice to come from and re-charge our kid's room, but after about two-weeks, mice still wandering brazenly in the room, nesting in bedding, zero effect. I've never heard of any study that indicated sonic items worked, but we were hoping, cheap enough to try and some users liked them, maybe for other types of pests, but we saw no effect at all on mice, which is consistent with some of the other user ratings we read. Oh, well...

not sure if it's working (1 week in) because I see a couple roaches still. I'll keep it plugged in and see if it works as advertised. I'll update this review in a few weeks for further review.***2 months in****This item DOES NOT WORK!I still see roaches in the kitchen, so I pulled out the "pest repellent" and there was a love roach ON THE BACK!! Fake item does not work, I feel like I wasted my money.

I'm not sure how many people actually use these but, every year when we go to the cabin up North we bring these with us. The cabins are closed up all Winter and in the Spring, spiders and other little creatures seem to invade the surrounding area around the cabins. I just had to by more after a couple years. I put one in my laundry room. I'm pretty sure these things work. I mean where ever I put them I never see anything. Sooo.. you be your own judge!! lol

I live in a studio apartment with a serious roach problem. They have taken over my kitchen and I was looking for serious help and decided this would’ve been the best option considering I have a cat. I left a couple plugged in in different areas around my apartment and left for Christmas hoping they would all be gone. When I came back, I saw no roaches and thought it was actually working until I started going through my presents and a roach crawled right between my feet. Awful. waste of money. Don’t buy.

I plugged this product along with another one to an extension cord outside and got about 4 feet away from a squirrel on our bird feeder and it didn't care at all. Just kept munching. So, I left the ultrasonic pest repellers plugged in and saw birds and the squirrel come back frequently to the feeder as before the repellers were set up. So if your issue is squirrels or birds. This isn't your product.I also used a sound meter to test whether these very light plastic boxes actually make sound and the results were no! These boxes do not emit sound. FYI - I tested other ultrasonic pest repellers we already had, and the sound meter did indicate that they do make sound. I suspect that this product may only be a plastic box with a cute light on it. AKA a complete waste of money.We are currently using a set of computer speakers with subwoofer and iPod playing very loud hip hop in our attic and the critters moved out the same day! They came back after a few days without music. So, we are keeping the music on as much as possible during the day and evening to keep them out. This is likely a superior method to any ultrasonic pest repeller (that actually does make noise) because the hip hop is constantly changing, unlike the ultrasonic signal.

Al principio parecían que funcionaban perfecto porque no se acercaban los moscos y después volvió a estar el lugar como antes lleno de mosquitos. No me gusta que se quede la luz azul prendida porque en la noche es algo molesto pero en general está bien porque te vienen muchos aparatos para conectarlos por toda la casa

No sirve, las hormiguitas salían del enchufe donde estaba conectado el aparato. Duro mas de un mes y nunca las ahuyento.

No aleja realmente a los insectos, pasan como si nada
