One of my favorite magazines (this was online though) recently had an article that I thought I would share. http://www.motherearthnews.com/green-homes/how-to-get-rid-of-mice-zm0z10zhun.aspx
I know that many people have mice and would love to keep them away, I know we sure do. I would love it if I never had to see little signs that a mouse has been in our house, never have to clean up after one, and never have to be surprised by the occasional sighting.
I have tried quite a few things and have to say that peppermint oil like this short article suggested does seem to work the best. Just an FYI though, I have to refresh the peppermint once every week or so. If I forget or get kind of lazy about it then it doesn't usually take long and another little house guest is back :(
But after trying all kinds of non toxic ideas, this by far worked the best.
Just thought I would share for those of you that might be looking for a little relief from the unwanted house guest :)
