Why freak?
What are you freaking out about? Almost every home I've remodeled over the past 35 years (including relatively new ones-and very high end ones) have had evidence of mice. Just like your and I, mice are looking for a warm place to sleep in the winter and regular meals. Call a pest control professional and get them under control. It may take a month or two. Plus maintainence. The best way to keep mice out is to not give them a food source and to not give them an opportunity for egress. Anywhere there is 1/4" gap or more, they can move through. And don't eat crackers in bed.
Whether you want to remove the dead mice and mice dropping by removing all your insulation is your choice. Your insulation value will not be measurably compromised to leave as is. If you're worried about it being a health hazard: IMO it is probably more mental than physical.
In my opinion, any level of rodent infestation can be dangerous. Tunneled, torn, and shredded insulation, and, frequent large groupings of mouse droppings can be a nuisance, however, mice are hosts for ticks and other parasites. Mice harbor and can transmit dangerous bacteria including Rocky Mountain fever and Lyme disease................
