, Ultrasonic Pest Repeller Control Reject Devices Electronic in Repellent Defender Home Indoor for Rat Mosquito Mice Spider Ant ROA, 4 PACK

Amazing, amazing, amazing!!!! These repellers saved my sanity! I had flies on my doors, sliding glass door, windows outside, on the stucco, on my front porch it sounded like a had a swarm of bees buzzing, but it was flies. I would have to do some kind of weird arm swing dance to shoe the flies before evey time I opened any door to come in or flies would be coming in with me. I have some chickens and ducks, the flies were on the food and water dishes, on the dirt, and on my animals. I hung fly traps, tape, those column sticky things, used my expensive essential oils to make sprays, and Pinterest posts on homemade cleaning mixes to no avail. They're area is raked, watered, and kept clean thinking the animals were the reason, but the flies didn't leave. I get these plugs and within a few hours most were gone. Left them plugged in around the clock and the next day NOTHING! I am fly free! It's just flies, but I feel so relieved. I have one plugged in about 10-12 feet outside from the animals facing them, one plugged in on my patio about 4-5 feet from slider door, which is then about 3-4 feet from the one plugged in for the animals. I also plugged one in the dining area of the house which is near the slider door. I didn't plug one in on the porch because those are gone too. Maybe from the other three plugs doing the work. I leave them plugged in 24/7...not taking any chances. In closing; these are awesome, they work, I recommend and would buy again. They also came nicly wrapped and packaged. ***update*** 8/18/19 Still have them plunged in and still working. A fly here or there, but plugs are doing a great job!

Bought about one set of 4 about 3 weeks ago. Sadly it only worked for about a week. I would still see very few mosquitos but didnt get bit like I usually would. They were plugged in the entrance (where theyd normally gather), my master bedroom, the bathroom, and the living room. Yet, somehow after one week everything returns to normal and the mosquitos are not affected. Was not happy with the fact that I paid for this with high hopes that my problem would be solved. Guess ill keep searching. I hope everyone else has a better experience.

I want you to know that I researched over 200 different ultrasonic pest repellents. I chose this one because it is safe for pets and children, but also has easy installation with good results. I bought this for my moms 4000 square foot house that was completely infested with rats and mice due to them being gone for a month for vacation. It was so bad that no one was making food anymore, and 15 to 20 rats running across the floor in the kitchen....house...ect. They were catching 10 to 20 rats and mice a day with rat traps. So i got these for her and put 1 in every room of her house...including bathrooms and garages....and within 1 week....there was no rats or mice anywhere....not even any sounds in the attic or basement....now theres alot left to clean...but they are completely gone! And she has 4 German Shepherds and cats in the house and none of them are affected by this product. Highly recommend this for rat and mice infestation....thats all I used it for...so I don't know how well it works for insects, bugs, ect.

I recently moved into a house in the mountains that wasn't well taken care of by the previous tenant. In my first couple weeks here I was consistently walking into nestlike cobwebs and having multiple daily stare-downs with some real gnarly looking spiders (intimidation is, after all, the best line of defense). When my scare tactics didn't work, I decided to give these sweet little spider-annoyers a try. I used one 4-pack for a 3000 sqft. house, and have had them plugged in for about a week now. The little leaflet that comes with them says to plug them in 20-40 in. above the floor, which was a challenge since most of my outlets are either much lower or much higher than that, and I wanted to space them out as well. I've still had to use intimidation and brute force on a few, more defiant a-holes in the last few days; but the incidence has decreased quite a bit.

2 upstairs, 2 downstairs.... Only been plugged in a few hours can't wait to see the results.... Or not see the bugs. Update: 2 days into it. The few ants I used to see are no where to be seen and our winged issues, flies, nats, and mosquitos, are no more. Great job. My dog comes home today so we shall see how well her hearing is. Ive now had it for almost 3 weeks, I'm satisfied with the crawly bugs but the flying bugs are still as present as if nothing was in there. So I'm not 100% convienced it works. I'll give it some more time.

I have multiple ZEROPEST ultrasonic pest control units plugged in to my living areas and bedrooms for over a year now. It's difficult to know how well they actually work, but what I can tell you is that our home is pretty much bug free. They are very easy to use. You just plug them in. I have had similar devices in a previous home that did not seem to work as well. The other devices also emitted a buzzing noise after a while. I cannot hear any noise coming from the ZEROPESTs. The blue nightlight is a nice feature as well. The glowing blue border at the top is always illuminated, but you have the option to turn on the brighter bottom blue light to use as a nightlight. Overall, I am very pleased with this purchase and would recommend them to others.

Easy to install. Received today put one in the garage, one by the front door and one by the back then one in the upstairs hall. We live in Hawaii and have had a lot of roaches around the outside of the house with a few dead ones inside. Hoping this helps keep them out. My only worry is that it says to install 20 in From the floor but don’t have a single plug that high up. Update: minus one star b/c after only 3-4 months use one of the four stopped working.. light will not come on and makes weird sound then dead.

I am a landlord in Chicago. Our winters are cold and it's not uncommon for mice to come on in for warmth. About one month ago tenants in two of my units reported seeing mice on a regular basis. My building is pet-friendly so I was hesitant about bringing in an exterminator or using traditional traps. And live traps would've been an inconvenience to everyone. I spent time reviewing all brands of pest repellers and decided on this product. BEST INVESTMENT EVER!!! I check in with my tenants often and they have not seen a single mouse since they plugged in the devices! I have to admit, I was skeptical in the beginning but if I'm ever again in need of a repeller I'm buying these, hands-down!!
