AVARZA Ultrasonic Pest Repellent – Indoor Electronic Repellent – Pack of 4 Pest Repellents – Effective Against Insects, Mice, and Bugs – Non-toxic and Eco-friendly – Plug & Play Installation

I placed two of these plug in units in my attic for rats. Did not see a difference for the first few days but soon noticed a decrease in their movement up there. Instructions said to leave devices plugged in for a minimum of 3-4 weeks.  I think this device works and will update my review in another couple weeks

I have recently moved into a row house. My main fears were my reality upon move in. Although the unit was pest free the first 6mths ultimately my neighbors way of living began to effect my living quarters. Every so often I would see a roach but the mice were becoming too much, and to top it off he was poisoning them and they were coming to my house to die frequently thus sending me on a scavenger hunt for the body.Since placing these around the house I haven't seen/smelt one mouse. I've seen one roach. I am sold and feel at ease in my home again. I love my home and was starting to get upset at the issues that were not of my doing.

I swear I can't live anywhere without a set of these! Im always paranoid of bugs and insects and ever since I discovered these years ago, I make sure I always have them at hand. I even buy them for my family members as well. They have all said how much they love them and how well they work. Ever since they started using them, they hardly see any spiders or ants around! Get them! you will not be disappointed!

I've had a bad rat problem in my apartment for several months. I plug in a hole in my wall and another appears a few days later. I tried traps , they soon outsmarted them. I tried rat poison , they outsmarted that. I tried these electronic repellents as a last resort because admittedly I was skeptical if they worked. Since I plugged these in every wall of the apartment. The rat dropping have completely stopped and there are no new holes! I am so happy my problem is gone

Hi - These work well, but I wanted to bring to your attention that if the animals you're wanting to deter have no way of exiting the home, this is a very inhumane device. If they do have a way out though, it's way more humane than a trap or especially a glue trap. No one wants to make the animals suffer needlessly. Thanks!

Just a little under a week of having all four plugged in, I can see the decrease in the amount of silverfish. At first I thought they were multiplying in my kitchen and bathroom areas but after about a week it seems to be finally clearing out of wherever they have a nest.

This is the second time I’m trying an ultrasonic pest gadget, but the first time from this company. I purchased it to get rid of the spiders in my apartment. Seems to be doing what it’s supposed to. I used to kill a handful of spiders daily, now I’m seeing a couple every few days. 5/5 so far.

Great way to prevent mice from settling in your place. Clear out time might be slower than I hoped, but it’s working for me!
