Cayenne pepper. I don't know what you would put in in... seal it up... maybe the end of some nylons (ladies) maybe a coffee filter?

Wife had mice chewing her insulation on top of her g80's motor... under the plastic engine cover... sprinkled the pepper on top of the engine... put cover back on... no mice in the two years since, and I didn't add new pepper.

My recommendation: cayenne pepper.
