Greenvida Ultrasonic Mouse Repellent - Rodents and Squirrels Repeller Pressure Wave Pest Deterrent Control Chaser with Anion Air Purification in 360 Degree Indoor for Insects Mouse Mice Rats

this works! but it is not liked by my dog...when it was in the basement or attic it was fine but when i put it in the downstairs bath [just off the kitchen where the dog is frequently ] my dog started shaking and acting weirdly . the animal in the wall left in ten minutes!! but my dog made me move it back down stairs . i put it on the wall in the basement bath directly below where the animal was in the wall upstairs and it is also working from there to repel the critter in the wall and the dog seems ok! so there appears to be a proximity thing going on ...if you have a dog bear this in mind!! the unit does work well otherwise ...everywhere i put it the mice disappear within days.

I ordered one and then, under the assumption it was working because I had not spotted a particularly vexing rat for two days, ordered two more. Unfortunately, I now have irrefutable evidence the first one does NOT work, so I am returning the unopened additional units. Save your money and buy lots of traps instead.

This product works well. I no longer see any ants or other bugs coming through my basement windows.There has no more reviews since #61 was posted. Is this product still being sold?

Definitely, works on house mice. Drove them out of my apartment one day. Didn't bother the dog. The jury is still out on whether it works on rats. Will update soon.

Mice definitely noticed when I turned it on, but did not repel them, even after a month of being on...

Piercing sound no matter where we put it. Dog couldn’t tolerate it either!

It seems to be working just fine; hope it keeps on keeping on.

This was very effective against mice. I bought it primarily for the rats in the kitchen and they seem to be gone. I haven't seen one in over a week. Extremely effective.
