The answer to 'why is my rodent scratching sounds' is that it's likely due to a rodent infestation in your home. Rodents like mice, rats, or squirrels may be nesting or moving around in your walls, attic, or other hidden areas, causing scratching, scurrying, or squeaking noises. This is a common sign of a rodent problem that needs to be addressed.
Rodents are often attracted to homes in search of food, water, and shelter. They may enter through small cracks or openings and start building nests, chewing on materials, and reproducing. The scratching and scurrying sounds are a result of their normal behaviors and activities as they move around your home.
