6 Pack Ultrasonic Pest Repeller, Safe for Human Pets US Standard Plug Efficient Control Mosquito Insects Spider Termite Flies Cockroaches Mice

I’m giving this product 4 star for its price and ease of use. I’ve had it plugged in to 2 rooms for 4 days now and so far, we have not heard any mice movement on the wall. I’ll give it another month and revisit my review if anything changes.

Not sure how well they work, because the second I plugged one in, my dog lost his sh*t.I've had good luck with similar products for mice (I have a wide range of hearing so I can hear the buzzing but it usually isn't an issue if it's in the kitchen/living room).It's probably not a health issue for animals, but my dog going nuts means I won't be using them. I'm also foolish and already got rid of the packaging.3 stars because if they bug him that much, they probably bug the bugs (pun intended) too.

A friend recommended trying these out and I did reluctantly because I didn’t know if they would work. And we have a dog who I didn’t want the sound messing with. First we tried one out to see if it messed with the dog and when it didn’t we set up the rest. I bought this more for the mice plus it is winter time so I haven’t tested it out on the other pests but plan to this summer. I will update my review then. Normally I find mice dropping everyday. They run around at night in our kitchen and I have a very clean house. I hate mice, but after a month. Nothing!!! No dropping. No issues at all with dog. No mice. I am one over the top happy customer. I strongly recommend you try these out if you have a mouse problem. I am very happy with this purchase. The price is great and you get 4 of them. I have no complaints.

These are worth it, kill all those termites type bugs I had. Came in my living room after a day or too of plugging one in there and I say what is all this on the rug it was a lot of dead termites or ant type bugs dead. I was shocked because didn't know I had that going on in my house.

We had one device like this and it seems to be working so we bought this 6 pack. Have only seen one small spider since plugging them in. Summer hot moths will be coming and that will be the real test of flies etc. We do like them a lot and are pet friendly.

It works for me for my house. My kitchen has some cockroaches go around after I use this, they just disappeared.update: few month later, it's not working anymore, don't know why. It's too bad >.<..............!!

This item is useless. I'm using it as directred. And big spiders and ants and stink bugs come in no less than before I plugged these in. So don't waste your money. And of course we are just a few days out of the 30 day return window and now I'm stuck with it....

We just moved in new home and lots of spiders and other strangers around. My cat was really freaking out i got ultrasonic repeller and all works really surprised helping a lot.
