We had 2 mice living in one room. Purchased these thinking with only two pests this should have removed them or forced them out of the room. Did not work at all!! Plugged them in, made sure nothing was too close ( garbage bin or furniture). Don’t bother purchasing these!!

I'm happy to report that these pest repellent devices seem to work very well. In the past, we've had problems with a constant army of ants marching across the kitchen counters, no matter what we tried to get rid of them - we could wipe out 50 in one blow, but by the next day there would be a whole new army.Anyway, since installing these about 3 weeks ago, our counter tops have been blessedly ant-free...and the occasional cockroach sighting has also disappeared.Hmm...after about 4 months of these working wonderfully, all of a sudden an army of ants walking around our kitchen counters has reappeared. I'm wondering if these things can "burn out" or somehow otherwise quit functioning at some point. Before this, they were working great - no ants or roaches at all.

You say that this keeps flies away. It does not keep flies away I still have them all over in my house. I sure hope it works for mice like it's supposed to cuz I know it doesn't work for bugs and such

Installed it everywhere in the apartment. I still see mice..Waste of time and money..

So far two months in and no less pests than before, will continue to keep faith and see how it goes.

I think these are helping with the mice in my home. I had similar type plugged in for a couple of years and never saw a mouse! However, someone I respect told me they do nothing, so I took out. One year later, I have them everywhere. I recently purchased them again! Hope it doesn’t take too long for the mice to leave!

No issues at all, just want to know how often should I change them out.

These don't work against roaches, 2 days after having them plugged in I have noticed more roaches than before. One crawling right next to it.
