Bell+Howell 4 Pack

This was my FIRST review - OUR FIRST WINTER WITH THE PRODUCT. SEE my SECOND review at the end of this one .. A YEAR LATER> I purchased this product for my family's 2 family house. My parents live on the 1st floor, I live on the 2nd. During the winter we were waking up everyday to "mouse droppings" all over the stove and counter, despite these places being washed down after dinner every night with Clorox lemon wipes. Peppermint oil being put on cotton balls and wiped on the counter is another thing we tried. After doing some research and talking to the people I decided this Ultrasonic Repeller was the way to go. I sent for them in mid-January. They arrived and we plugged in 2 on each floor. I feel I have been more then patient and have given this product a fair test (2 months). While there are fewer droppings, the mice are still here and still leaving their "little gifts". The light is blinking every 4-5 secs, since we can't hear the tone it supposedly gives off (sound that mice/bugs hate), I have to assume that either it doesn't bother the mice, they don't care or they are deaf or there is no tone and it is all a con because I can tell you -- These plugged in pieces of plastic are worthless pieces of garbage. THEY DO NOT WORK! SECOND REVIEW - I left the product plugged in for the year, it wasn't in my way. I did notice fewer spiders and those awful stink bugs. But the best surprise was the winter... NOT one mouse all winter long. From talking to people who have had these critters while the product does work, but it has to be in place and operating before the mice take refuge in your home for the winter. Once they are in and have their babies while the noise to them is horrible they can't leave. Which explains when the weather got nice they moved out and as long as the pest repeller stay plugged in they don't come back. We are now on our second winter, mouse free.

I started buying these a few years ago when I lived out on a 1000 acre ranch and had 25 mice all over my kitchen every night. They cleared them out so fast. Then my next place had roaches when I moved in, and again, these things cleared them out. I have seen flies fly in and turn around and fly out when I have these. I noticed that my dog stopped getting fleas when I had these in my house. The only thing you need to know is you need to rebuy them ever 6 months as they loose their effectiveness at that point. So I just replace them. With these installed in my house, I have also noticed NO spiders, and since I moved to Georgia that has a ton of bugs that I have never even seen before, once I got my new ones for my new place I stopped have strange creepy crawlies in my apartment. I tell you, you haven't seen bugs till you have lived in Georgia!

I waited almost a month to write this review wanted to give it time to see if it works. We have a small 2 bedroom house we have one in each room, one in the living room and kitchen (4 come in the package). We still have a minor issue with a rodent. IMO this product does not perform as it stated it would, therefore we will be returning it while we try and come up with another solution.

It’s good with the stopping the rodents, but I am still seeing baby roaches.

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 2013.12.11 The 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 2013.12.15 The 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.

I purchased this repellent for an elderly lady & it seemed to do the trick. They are definitely easy to use & reasonably priced. They are a nice weight & size, and seemed to be effective. They emit a sound that keeps pests away but doesn't bother people. I can't think of any negatives. There is no poison!

I bought these as an experiment. I did not want to use insecticide in my kitchen. So far they seem to be working. the trick is to use electrical outlets with a clear view of the problem areas.

I already had this brand for 15yrs they really did the job! Wanted to buy the same brand.

Doesn't seem to work, there is a spider living in a web right next to it. The device also has a VERY bright light that comes on a night.
