The answer to 'rat trails' is that rat trails are the visible paths or tracks left behind by rats as they move around. Rats are creatures of habit and will often use the same routes repeatedly, creating distinct trails on floors, walls, and other surfaces. These trails are a common sign of a rat infestation and can provide valuable clues for identifying the source and extent of the problem.
Rat trails are typically found along baseboards, in corners, or in other areas where rats travel frequently. They may appear as dark, greasy smudges or as slightly worn or flattened paths. Rats also leave behind other signs of their presence, such as droppings, gnaw marks, and nesting materials. Identifying and addressing rat trails is an important step in effectively controlling a rat infestation.
