A member asked:

How long does squirrel feces/urine inside walls decay? i have been sleeping in a room for 11 years without cleaning the inside walls of urine/feces

A doctor has provided 1 answer

Not a problem: The urine dries quickly and the feces dry as well. They do not lie in wait waiting to attack you but simply become inactive although a concentration of feces might attract other pests into your walls. A good coat of paint will help isolate your living quarters.
