Bell + Howell Ultrasonic Pest Repellers, 4 pack

This product rates no stars. It doesn't work! You also gave me a hard time when you said my credit card was invalid -- 3 times! Even when I talked to a salesperson over the phone. Not so! I've been using the same card for years and had even just come from the grocery store where it was - as always! -- accepted.

They seem to have worked. You can't expect to not see any more spiders, just because you plugged them in, But you will see curled up spiders on the way out. And then, no more bites. Hallelujah!

I am sorry to report these aren’t working the way I had hoped. I have placed multiple ones throughout my house in hopes to deter the mice. However I have trapped 6 mice directly under one of these that I placed in my kitchen. I’m hopeful they are helping in some way but I definitely don’t think they are deterring the field mice

The product is as stated. The ultrasound frequencies work very well. It repel the critters incredibly well. I definitely recommend.

I'm not too sure about the merchandise but I am sure about Chewy. I love them! Not only are they efficient but they are quick with their delivery!!!!!! LOVE CHEWY.

Hope springs eternal and I was "gung-ho," for this product as it might be a way (any way) to get rid of my unwelcome furry guests that didn't use spring traps or poison bait. When plugged in, my dog hid in the closet. You could almost hear him whimpering "turn it off...turn it off." After several days of being plugged in, I returned home to find the mice having a party, chasing each other around right under these useless devices. The dog in the closet looked at me as if to say "can you make them go away!" I have no idea if these pest repellers get rid of spiders but...I'll ask one next time I see one. They certainly don't work for fleas either.

I was looking for a humane method of handling the mice in my stable. I turn these on every night and unplug them in the morning and they seem to work well. Mice are no longer running around me when I feed at night and are not jumping in my horse’s food bowls without killing any mice!!

Was hearing something chewing/ scraping around Behind the Walls, towards the ceiling, probably in the Attic and purchased this because I don't want to crawl up into the Attic or kill anything / handle anything that's been killed. plugged one in just beneath the noise and then another one just beneath the entryway to the Attic. The noise moved over to the other side of the room immediately. I plugged one in on that side. After a few days, I didn't hear anything there either and haven't anywhere since. Has no effect on any one of my three kitties. Didn't have bugs before... So I can't tell whether or not it's effective against those

Bad product -I paid for the 8] Igot.If I had known I wouldn't have taken them if I had been paid.

These do not work I ordered atleast six at once. Plugged all of them in and still see spiders in my house.
