Bell + Howell Ultrasonic Pest Repellers, 4 pack

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.

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

These are the worst! They make a clicking noise and the red indicator light blinks. I did some research and no review shares that the devices makes a clicking noise & the red light is a continues blinking. Annoying. I am returning them. Side note: Black & Decker made a great one, I’m sad they don’t make it anymore. Completely happy with Chewy.com! Chewy.com your an amazing company!

I just bought these because they are on sale and I have had good experience with other brands of ultrasonic pest repellers.... BUT the flashing red light is not going to work out for me.... guest room, bedrooms... won't be able to use them...

I’ve been using these for many years to rid my home of ants. We live near the water with lots of sandy soil and the ants were horrible when we moved here over 20 years ago. After exterminators, and countless chemicals , I tried these , and omg they work great for ridding your home of ants. It takes about 6-8 weeks, but then all of a sudden, they are just gone.

This product does not work I live in Florida so after it rains we get a lot of palmetto bugs the big cockroach and I have it all through my house I brought two packs which cost me $40 ants do not care nor the roaches do not care about the sound waves a waste of money please I recommend to not waste your money

These may work in other homes but not in my house. I still have mice rooming with me. I have caught numerous ones and put them outside. I find them a waste if money

We just moved and the place was infested. So we sprayed and bombed and got them almost clear but we still had a few intruders. I bout this with hope it would help with the few that got away but instead its attracting them. I unplugged one to use ny vacuum and they were just hanging out being it bc its warm. Now the package did say a few would be immune but it literally does nothing but click and light up and the bugs are using them as a heated home.

I live in a small studio cottage in the mountains and get lots of critters. I bought these and put all four up near my kitchenette where the biggest problems occur. So far, I haven’t heard any mice (though I still see there droppings). But the ants and spiders could care less about these devices. They keep swarming all over my 600 sq ft cottage.

I decided to try these because little bugs were coming in on our feet or paws. I plugged them in and so far no bugs.
