Can Monterey Consan 20 be used to kill mold on Sheetrock?

The manufacturer does not recommend that you use the Monterey Consan 20 on sheetrock. Sheetrock retains a lot of moisture, so the better solution would be to remove the sheetrock and insulation, treat the wood studs in the wall with Bora-Care with MoldCare, and then replace the insulation and sheetrock. Please look at the regular Bora Care with Mold Care which will kill and prevent future mold growth on a variety of surfaces including wood, cellulosic drywall (sheetrock), and concrete. You may paint surfaces after you have treated with Bora Care with Mold Care and allowed it to fully dry which should take about 72 hours.

Can I use Monterey Consan 20 to spray on attic insulation where roof rats have deficated?

No Monterey Consan 20 would not be used in an attic.  Nisus DSV can be used in attics and almost any area to clean up rodent or any other pest droppings and will not harm insulation, wood or other materials within the attic or treatment areas.  If possible though it would be best to replace the insulation.
