It emits blue light when it works, makes no noise, has no effect on sleep, has been used for a few days, and now I can't hear mice at night. I left the product plugged in for a month and saw no reduction in spiders or those dreadful stink bugs. The best surprise, however, was the house... There isn't a single mouse in my house.

They do an excellent job. Because we've been using them in various homes for years with excellent results. We have two devices on the same circuit in the basement, and I didn't notice them tripping on ground fault. Rats were discovered for the first time this spring as a result. So I reset the ground fault, it worked fine for a week, and there were no more rats.

This one was chosen because it is pet-friendly. I had to remove my cats from their rooms for a couple of days before I could spray the area with repellent or ant killer. I had to always deep clean and wipe away any residual drug before reintroducing my pet babies. I got this device and it has made my life so much easier! I just turn the switch on and leave the device in the room!

I've been having an issue with house flies. I live in a basement and kept my door open often for air and my pets. This attracted flies. At one point I noticed Fly larvae by the pet food. Even as I rid the larvae, the flies kept coming. I suspect they migrated within the crawl space and I actually caught the second round of larvae. I purchased this product, which claims to provide optimal results in two weeks, but I saw results in one day.

I was skeptical about ultrasonic pest repellers before using them, but after using them, I believe you will not believe your eyes as I did, because they really work.

My mutts have been alerting me to something within the divider of the additional lavatory tub slow down where I live. I had my pest control company come out, and they kept telling me that I could hear reptiles on the exterior stucco divider. I swear I heard a squeak the other day and had had enough. I ordered these, and when I stopped it into the outlet, I heard all sorts of commotion beneath the tub, as if whatever it was was attempting to get out of there. I've since stopped two in that restroom and one in each of the rooms adjacent to that divider. Pooches have not been warned about the tub, and everything has been quiet since.

I only installed them two days ago, but they appear to be working already; we are primarily using these for roaches, and I am seeing the activity described in the listings, and it will be gone soon; I believe these work extremely well.

I bought these after catching three mice in two days in our living room. We live in the country, so mice are plentiful, but our toddler insisted on feeding them (leaving food everywhere), so I wanted to give these a shot. I would hear activity in the cable hole where they used to come out after installing them, but none of them ever came into the room. I'm not sure what effect these have on bugs; we got them for mouse control.

My children have been bitten by bugs since we moved into our new home. We haven't been able to figure out what the bugs are or where they're coming from. Then I saw this device, so we bought it, and my youngest son hasn't been bitten by bugs since it was installed.

We purchased a cottage and converted it into a house. We have bugs almost every day (ants, spiders, and some I'm not sure what they are). We would have ants on our counter tops every day and would have to use an aunt spray full of chemicals weekly to reduce the problem. I haven't seen a single aunt since we plugged these in, and that's only because it takes time (months) for the critters to scatter, as stated in the instructions.

I used to have the worst spider problem ever. So much so that I would wake up with a spider crawling on me. I never had a crawl on me again after installing 6 of these throughout my basement suite. I did spot a few, but nothing like before.

This year, we discovered a couple of mice in our basement ceiling. We even heard something running in the ceiling one day, so we set traps and it was caught. We haven't found anything in the traps since we installed the pest repellent device in the ceiling more than twenty days ago.

This item is fantastic! We've had a subterranean insect problem in our kitchen for quite some time. We tried non-toxic "fixes" from the internet, but nothing worked. We installed four in our kitchen and began to notice fewer and fewer ants as the first two weeks passed. It was like a supernatural occurrence at that point; no ants!

We are quite upset with the mouse in our garage. We have been using this for a week and have been pleasantly surprised that we have not felt any mouse activity or mouse itself. Very simple to use and appealing to the eye.

These were purchased on 10/10/2022. Nothing has happened in nearly 20 days!!!! We used to see earwigs, spiders, and the occasional water bug. NOW??? Absolutely nothing!! We are astounded because even when it rains, we may see earwigs—we've been told they come from the flowerbed—but NOT NOW!! WE ARE Incredibly happy!!!!!!!

Installed in the kitchen, basement, and garage for a few weeks now, I haven't seen a mouse running in the kitchen during the quiet time they used to be, and no mouse drop to be found in the garage or basement, so it appears to be working properly. I chose this one over others because it does not block another receptacle when plugged in, whereas others take up both receptacle space when used.

I used this one for over a month and discovered that it works and can get rid of insects. This does not produce instant results. It improves over time, but it is very simple to use..... Simply plug in, and good results are visible after about 2 weeks.

When insects buzz around the house and the stench bothers me. The insecticide I bought was ineffective. Then I discovered that insect repellent was available for purchase. It was the first time I bought it. Because a small spider was nearby, I used it as an experiment. The spider remained for a week, occasionally shifting its position. After two weeks, I discovered that it had completely vanished.

I had a swarm of fruit flies in the kitchen that I couldn't get rid of no matter what I tried. I figured I'd give it a shot; it's easily returnable if it's ineffective. But it makes me clean out all the pests in my house! IT DOES WORK!!! Money well spent, and the problem appears to be resolved.

They were simple to install; simply plug them in. I had ants in the kitchen before I got them, so I bought ant powder, which is not good for your health, but this pest control device is better, with no chemicals or poison. Right now, I'm not seeing a lot of ants, but I'm hoping the ants and other inserts will be gone after a while. It came with six, which I placed one on each level, with two in the basement.
