Every single year we get a flying bug infestation! These bugs are NOT bothered at all by many brands of bug sprays. In shear despairation, I put one of these in EVERY outlet in the room where they seem to be coming in...we still don't know how...it worked! It is now the height of their season and NO BUGS!

I think they work, because I do find bugs that come in the house from under the doors and stuff but they usually did. So I choose to believe that it’s working.

The media could not be loaded. I bought these for the new house I was moving into, since the price on the ones I have used for the past 5 years doubled sadly, and not sure why but I threw them out. These are well, after spraying the home I still see bugs, but they are annoying, as they click, or make a ticking sound. I have had them up for 2 weeks and looking to return them.

For some reason last year we saw evidence of mice in our garage and we have never had that issue over 22 years. Previously we had the smaller plug in devices we got at a local hardware store. So assuming they had stopped working, I took a chance on these. No more evidence of mice so far and its been a year. Now, there could always be other factors involved but for the price - this is peace of mind.

Helps to keep bugs away

These work as good as past ones I had from Bell and Howell. My last ones lasted over 5 years.I have seen a bug or two, but the were dead. So they work.

Recommended by family. First time purchase. Came in multi pak of 4. Purchasing another 4 pack.

I live in a slum community in South America where there are lots of pest especially large rats, spiders, roaches centipede....I was consistently purchasing rat poison to get rid of rats that would run into my apartment from outdoors but they just keep comming...not to mention i would find one or two large centipede like snake visiting my apartment from an nearby sawmill....i decided to try this product and it worked very well... i placed this product in my kitchen, doorway and sleeping area and i noticed only one small mice visit my apartment but would look a little shaky and try to run out....i suppose many who purchase this item failed to understand the principal of ultrasound..ultrasound cannot penetrate walls and objects however it is reflected or rebound from objects.. therefore if u want this device in a area where there a lots of obstacles then rats can still lurk nearby because the sound is not reaching their ears. so placement is a great factor for effectiveness...i forgot to mention too a large one feet rat visit my home and hid in the corner of my wall (as usual) but it suddenly ran out upon hearing the sound..i cannot say whether this device works on getting centipede out but i will update my review upon further analysis.To conclude, DON'T EXPECT THIS DEVICE TO KILL PEST OR STOP PEST REPRODUCTION IT IS ONLY INTENDED TO REPEL THEM.UPDATE 2013.12.11The devices works prefect for mice and rats but not spiders...i have a spider building its nest right in front of this device..wish i can take a picture and post it..however my main problems were mice and rats and i am glad that it solve my problem. However, this led me to the conclusion that the ultrasound sound given out from the devices is specifically designed to repel rats and mice only.UPDATE 2013.12.15The Devices does not have any effects on mosquitoes. i place one of the device on my wall in open air next to my bed..i noticed a couple of mosquitoes lurking on my bed netting. hope this helps those who are experiencing a mosquito infestation.
