Best Premium Non-Toxic Chemical Free Ultrasonic Pest Repeller Made to Help Repel Mice, Roaches, Ants, Spiders, Flies, Mosquitos and other irritating pests. Safe for the Whole Family

We have had these about six weeks now with one installed in our garage and the other outside near our deck. There had always been a problem with flies in the garage and they would always come into the house when we opened the door from the house to the garage. Now there are no more flies there and I have to think it is more than a coincidence. Flies will enter the garage when we open the main garage door but they don't seem to stay. I don't know about other insects because they have not been a problem. There is no noise that we can detect.It is not as clear how effective the pest repeller mounted outside near the deck has been. Our patio table where we might eat is 15 or 20 feet away. There have been a fly or two when we have food on the table but otherwise it does seem that there are less in the area.I would buy these again. At the beginning I was very skeptical. A few years ago I bought what was a popular mosquito repellent/killer which was far more costly and never worked for long. I ended up dumping it. These ultrasonic repeller are not expensive and require no maintenance. You do need an electric outlet which limits where you can place them but that is a small inconvenience compared to what they do.

I wasn't sure what to think when getting the four of these that I purchased. I had a smell coming out of an electrical hole in the floor, the last few months, that smelled like mice, I put one of these beside the hole and within one day the smell was gone. We still see a spider once in a while, having only had these maybe a week, but things are much better. I think I can avoid calling the exterminator!

I was hopeful but had my doubts this little gadget could keep the flies away but it has! We have been using it for about 3 days and after about the first 24 hrs there was a noticeable reduction in those annoying house flies. They seemed to be coming from the garage when the dogs go in and out the doggie door so I plugged the other one in the garage. I am also happy to report that it has taken care of the fruit flies and I have some peaches ripening on the kitchen counter right now.

I had a significant spider problem at my house. I used several insecticide's but I was still killing 1 or 2 spiders a day inside my house. I started looking for alternatives to poison BC I was afraid my 3 yr old was going to get bitten or get sick from the insecticide. I bought this product 10 days ago and I've only seen one spider in my house since. I'm very pleased with this purchase and its effectiveness.

I purchased one set of these for my house and have since purchased another set for my dad's house. This product works extremely well especially with all flying insects - e.g. flies.

I plugged it in on my daughter's patio in Georgia. The roaches stay away but it doesn't seem to help the mosquitos at all. I was hoping it would keep them out of the patio so pretty sad about that

Doesn't work!!! No other words to be side

These do not seem to work at all. I'm bummed. I've had an ant infestation and I was hoping these would work. Back to the drawing board.
