What indicates a serious rodent infestation in terms of droppings?

The presence of numerous droppings is a significant indicator of a rodent infestation, particularly because even a small number of rodents can produce a large quantity of droppings in a short period of time. Mice, for example, can produce approximately 50 to 75 droppings each day. This rapid accumulation means that a minor mouse infestation can quickly escalate into a serious problem, with dense clusters of feces indicating a high population density.

In contrast, minimal droppings do not suggest an infestation, as they are typically more associated with lower rodent activity or isolated incidences. The statement that only rats leave droppings is incorrect, as both mice and rats are known to produce feces. Furthermore, suggesting that droppings are always easy to clean up overlooks the health risks associated with rodent droppings, such as potential transmission of diseases, highlighting why identifying the scale of infestation via fecal matter is crucial for effective control measures.
