What is a sign of rodent infestation?

A sign of rodent infestation is indicated by the presence of runways, burrows, and droppings. Rodents often create specific paths, or runways, that show where they frequently travel, typically along walls or in hidden areas, which makes them easier to spot during an inspection. Burrows are nests or homes that rodents dig into the ground or find in hidden spaces, which can signal a larger population in the vicinity. Additionally, rodent droppings can be a direct indicator of their presence, as they tend to leave droppings near their food sources or along their travel routes.

While visible nests made of grass might indicate some form of nesting, they are not as definitive for identifying a rodent infestation compared to the combination of droppings and runways. Unexplained noises at night may suggest activity, but they do not provide physical evidence of an infestation. Food packages that are unopened suggest that rodents have not accessed them yet, hence not serving as a clear sign of rodent activity. The combination of physical evidence like runways, burrows, and droppings is crucial for accurately identifying a rodent problem.
