Ultrasonic Pest Repeller 4 Pack Pest Repeller for Insects Ants Roaches Mosquitoes Mice Spiders Bugs Flies Rodents, Non-toxic Eco-Friendly Humans & Pets Safe

You might ask, how do you know these Pest Reject units do not work. Well when I returned home from being away 4 months I had 5 grey four legged critters, common mice living happily and warm where we normally do. They all had to go by 3 units. One was placed at the entry point. Don't ask long story... and the third in the same room where we had some grass seed stored for this seasons planting. It was their food source for a period of time. I cleaned up the seed mess and planted a single Victor mouse trap in its place. I caught all five in a 4 hour period. Make your own conclusion.

Purchased these pest repellers for an added backup for pests in the basement (i.e. spiders, mice, etc). The product was received quickly which was nice and they seem to help a bit with the larger pests - still had some minor sugar ants in one area of the basement.But after 3 months, two out of the four repellers died. There is a light on the front indicating power and two have died. I’m just waiting on the other two to eventually go out, too.Frustrating, because I had these growing up in my childhood home and they always seemed to work. Then again, they don’t make things like they used to.

I wrote a "haven't tried it yet" report, but now that Spring has indeed sprung, I have been finding dead of dying roaches in various places in my house, so these things are working! Am going to purchase more for other rooms and for a storage room. In the South, pest control is absolutely necessary and so far I am quite pleased!

Got rid of mice like it states. Have recommended it to others, and have given a couple of extra ones to friends who were having same problems. Worked well for them also.

Found droppings right in front of unit

Doesn't work at all. Not even a little bit. Don't waste your money.
