Rat urine poses such a significant health risk that Abolish Pest Control recommends the use of biohazard suits, complete with gloves and respirators, when removing it. Waste removal experts focus on attics as the main nesting area, using vacuum cleaners equipped with special filters.
Any kind of clutter gives rodents cover to travel in and out at will. Use a black light to detect rat urine. The average rat urinates 300 times every night. Each drop will show up under black light (much like some other substances that police investigators use black light to detect in crime season investigation). Where you see rat urine, you have rats.
