GROSSSSSS!!! I just went to get my frying pan from the drawer under my oven, only to discover my oven mitts chewed on, my frying pan chewed on and mouse poop in it!!

HELP! I have never encountered anything like this before, and I have no idea what to do! Do I need to throw out everything that was in that drawer? Wash it all? Get traps?

Any advice is good advice!
