I've heard that story for years and I consider it sort of an urban myth. I've never seen much success from it. My best luck has been to just eliminate or at least drastically reduce the population of mice in my farm. I have "blue blocks" of poison nailed in the wall studs of most buildings so any mice that come to visit will get a helping of poison to shorten their lives, hopefully before they find their way into my vehicles. Its not hundred percent effective but is the best method I have found to date. It is rare to see a mouse here now. One warning though, do not allow pets or kids access to the buildings where these poison blocks are located.
