The answer to 'rat odor' is that a persistent, unpleasant odor is a common sign of a rat infestation in your home. Rats leave behind urine, feces, and decomposing bodies that can create strong, musky smells. The odor is often most noticeable in attics, walls, or other enclosed spaces where rats have nested.
To address rat odor, you'll need to locate and remove the source. This may involve setting traps, sealing entry points, and thoroughly cleaning and deodorizing affected areas. However, if the infestation is severe or the odor persists, it's best to call in a professional pest control technician who can properly identify and eliminate the problem.
