Mice like the foam. It makes a great insulated "home".  They will nest in 
fiberglass as well.  Try stainless steel "Chore Girl" scrubbers to add 
structure to the foam.  I've also heard of layering the foam with hot sauce 
and/or cayenne pepper.

I have the same problem only with mice.  They chew away insulation on the 
They can squeeze thru a very small opening.  I'm thinking of trying either the 
duct seal 
or the expandable foam for these critters.   Anyone had success with either of 
these for mice ?
