Plug-in Rat & Mouse Repeller

What’s the verdict on these - work or scam? We’ve got something running around in our ducts, cant find it & don’t want to try poison.

So freaky.

Will this work to run squirrels off bird feeders? Can it be used outside in a covered, but damp, environment? Thanks.

The manual is available on this page.

I’m reading it as best inside buildings.

Bummer…I was hoping this was a cat repeller. I know a dozen people who would buy it if it kept cats from wandering into their yard. Could someone get with building that please? Thanks

The verdict has been clear for a long time. These do not work. At all!
