House mice and rats are not very nice critters. They use their urine as scent trails. They both urinate and defecate on food stuffs and surfaces. Sadly you have to bite the bullet and deal with them.
They can also be very expensive as they have been known to chew through electricity cables in the roof space and cause fires.
We had to have our living room replastered because one escaped to behind a bookcase. When I moved the bookcase to get at the mouse, the plaster on the wall fell off.
