, 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*** 8/18/19Still 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.

One day I came home and ALL of my windows in the living room and kitchen were STACKED with flies! It was the spookiest, most bizarre thing. I would kill nearly all of them and then more would be back by the time I was home from work. Tried essential oils and they barely made a dent because the flies actually LIKED the diffuser! I live in the Bay Area (aka our building doesn't have AC so opening windows is a MUST when it's hot. Anyways- I killed all the flies invading my home this week so they wouldn't be persuaded to stay trapped, plugged these in, 1 in front of each window we typically open/may have a draft that they're crawling in through.. It's been about a week and I've only seen 1 fly (and that's because they're trapped in here and scared to go near the windows. My only negative is that these plug ins have an ongoing blue light that can be distracting if you're trying to sleep but if you're on the market for a night light, you can press the button and the lower half will also light up.

I bought this to get rid of a mouse I recently saw in my apartment I placed one in every room and for two days I didn’t see it and no mouse poop anywhere and all my spiders are gone but, today is day 3 and I just saw him he run into my apartment from my heater vent.I’ve never had to deal with mice before so I have absolutely no idea how to get rid of them but I was really hoping this would work :( if anyone has any advice please share!

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.

Was looking forward to these after a recommendation. Very cool looking plug-in BUT when a bug crawled across me at 2 am I called a Pest Control Co in the next day and put out store purchased baits. Have not seen any since. BTW...Owned 5 different homes and never had a bug in my bed and one of the plug-ins was in the same room.
