Fiberglass insulation that doesn't stay wet or attract mice?

If using any spray foam, use high density polyurethane. I think 6 lb density or better, from what I have read. But what about XPS sheets? The pink or blue ones depending on which store you go to. The only problem with them is getting the right glue that will hold them in place... some folks rough up the surface with sandpaper to help glue adhere.
