Very good! Mice stopped showing! Thank you!

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 haven't noticed these having any affect on even the lady bugs that we have an abundance of here every year .. I have them in an open area free from absolutely everything and anything that could disturb the travel of the sound waves. I'm my room it's located roughly 2 feet from the window pointing towards it and still there are lady bugs there.. in my son's room, his if also in an open area directed at the problem window, his however is about 10 feet away from the window.. I've also cleaned the windows and put peppermint oil around them as well and these devices do not seem to have reduce or eliminated them. It says in the description that it's safe for your household pets because they can not hear this noise the unit puts off however I am very much questioning that because I myself can hear it, very faintly but I can definitely hear it. It sounds kind of like the zap noise you hear when you have something metal that touches a wire and you blow the fuse.. I find it hard to believe if I can hear it that my dog's can not hear it.. I will say, regardless of the fact, in no way does it seem to bother either of them.. so I would've necessarily give a bad review as far as safety goes for the household pets. I'm assuming I'd be able to tell if it were bothering them and that doesn't seem to be the case at all.. Overall, I wouldn't recommend this product for even small insects and I feel safe to say the chances are minimal it would have any affect on anything larger.. I'm giving this a 5 star for ease of use you're literally plugging it into an outlet and you're done. There's no parts to put together, instructions you need to read on how to assemble it and other than the free seconds it takes you to plug this into the wall, it's simple, easy and quick. The size of the product I'll also give a 5 star. You can very easily plug the unit into the wall outlet without covering both outlets which is important in a place that you may have limited amounts of outlets. I've not experienced any sort of odor from these at all.

Still seen a couple bugs come through my small apartment but overall less bugs to worry bout.

Just what I needed. Easy to use

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 have bought so many! These actually work! Keep the area clean and it will stay clean. Ordering more. I live in the county. Keep them off the counter and put the traps on the floor. THEY WORK. I AM SO PLEASED AND AMAZED! Stop getting those cheap ones from Chinese manufacturers. Amazing! Wish they had something to kill moths!

I have used the Bell and Howell Plug Ins for Pest Repellant for several years in different state in different apartments and they have always performed well. Very good product and would highly recommend.
