If there is a tremendous accumulation of rat feces and urine in your attic insulation, usually the only way to get rid of the terrible odor is through a total attic restoration. Attic restorations can be costly. Urine-soaked nesting sites will filter through the insulation and create unsightly, smelly stains on the ceilings below. The removal of soiled insulation, often a primary target for rats, demands meticulous handling and disposal to prevent health hazards, further adding to the cost. Extensive damage repair, such as wiring or structural components chewed by rodents, requires skilled tradespeople and materials, escalating expenses. Replacing insulation and repairing ceiling damage may seem expensive, but are essential for ensuring a safe, healthy, living environment. Proactive measures and regular maintenance can help reduce these costs by preventing infestations in the first place.
