BRISON Ultrasonic Pest Repeller - Electromagnetic Pest Repeller Plug-in - Prevents & Drives Away Mice Rats Spiders Roaches Ants Rodents Squirrels Bats – [1 Pack] (White 2Pack)

I plugged one into the entryway in the front and one into the entryway in the back. Because I did not know if it worked for certain size areas. I do have a bug zapper in the front, and it took care of the bugs that flew by, fatally attracted to said bug lite. Life was good but I had a bug zapper in the entry way. It was the first thing people saw. I saw these sonic things advertised somewhere. Remembered that a friend had something similar in her house(only one). She pretty much had the same thought I did. "Well, the bugs are gone. (Mom has not complained about them (I am her caregiver)), so that means it works, right?" So we are sitting here without bugs. Bug zapper is unplugged and has been for a month or so. It did take a few days or weeks to work. I saw bugs and was irritated, then I did not. Happy us!

In my pre-purchase research, half the internet were convinced they were a scam/ waste of money, etc. The other half said they worked on certain vermin etc. I took a chance - I have a large garage (2400 sqft) on the edge of a forest. I’d open the door to the sound of squirrels, rats and mice fleeing through the rafters and sheathing. Since installing 2 devices 2 months ago, at about 18” off the floor, I now open the door to silence. From experience, they work! Now the squirrels treat the roof like a parkour obstacle, but at least they are outside..

They work for me, keeping out insects of all types. However, they don't last very long. Hopefully, I can send the ones that stop working back.

The mice walk right by this damn thing and stepped on the glue trap if I wasn’t afraid of them I would posted a picture.

Have not seen any signs of mice since using this product and very happy about the price , the only on in our house that is not pleased with this product is our cat she’s not happy with our purchase at all
