Get a little more nitrogen into your compost so that it really starts cooking ( ie mix in some fresh stable manure) and cook the little varmits.
On the other hand, if you have a soft heart, you could leave a basement window open. With these cooler nights ,I am sure the mice will be happy to abandon the compost pile and raise their offspring in the warmth of your home :-)
If you lived a little closer, helping you out would warm my Dachsies hearts.
