Bell + Howell® Ultrasonic Pest Repellers 3 ct Carded Pack

[This review was collected as part of a promotion.] These types of things are always difficult to see if they are truly effective or not, but I will say that since installing them that we've seen less spiders in our house than normal. They take up a single plug but have a large coverage area and you don't even realize they are there.

[This review was collected as part of a promotion.] I received for free from influenster the bell and Howell rogue ultrasonic test repeller. I am going to give a very honest review on it. I have been using them all over the house for the last three weeks. I still have seen bugs and spiders. I do not feel that these work as well as they should. Don't think I would buy them myself.

[This review was collected as part of a promotion.] I live in an older home and occasionally I do see sings of mouse life. The idea of these is great. I've not had them long enough to know how affective they are. There's one for each room in my house, Different sizes for different rooms, no noise (except for an almost indistinguishable soft click). The only downside I found was the bright red light that flicks. I covered those and after that, no complaints.

[This review was collected as part of a promotion.] I was excited when we received these but they do not work. The noise is not bad at all. They do not do anything besides make a sound when flashing red. We have a couple of big roaches in our garage, due to the heavy rains, and they pass right through them without fear. So nope, they don't work!

[This review was collected as part of a promotion.] These pest repellers are great. I have used this type of device before but they have all clicked loudly every minute or so and if you are within range, it can become annoying. These don't have a sound. I placed them in outlets near our doors to deter pests from getting in. I love the largest one, because it has a plug on the side so you still have a plug to use. I think this concept works. Of course I can't prove it but I am no longer seeing bugs and I love that I am not using chemicals.
