While waiting for these to arrive, I placed peppermint oil around the pantry where mice were having a party. That works well but you need to keep it up. When these arrived, I plugged only one in the pantry and one in the upstairs kitchen. Haven't seen or heard any critters since.

These don't seem to work at all. Have had then for a couple months and the rats and mice in the attic have been coming down all the time. This has no effect on them at all.

Does not come with complete instructions. It has five modes but you have no idea what they are.

Sooo, yea... This didn’t work. I think this called more mice. I started seeing them more. I waited a month to see if anything would change and it did. I’m pretty sure this creates more mice activity. Although, I didn’t conduct a formal research study or anything.

I placed them outside to rid rats. So far, they appear to be working. I had previously caught 7 in traps.

Waste of money, I am thoroughly disappointed.. Not only is the description inaccurate, but is an outright lie. These things DO NOT repel rodents, if anything, they invite pests.

Doesn't get rid of bed bugs but other bugs are gone.

Great nite lite, not sure about the repeller part. Cause I still have spiders.
