What size are the droppings of an adult Norway rat?

The size of an adult Norway rat's droppings is typically around 3/4 inch long. This measurement is important as it helps in identifying the presence of Norway rats in an area, which can be crucial for pest control and management. Accurate estimation of droppings can indicate not only the species but also the level of infestation. Understanding these sizes informs effective control strategies, as different rodent species can have droppings of various sizes and shapes. The other options either understate or overstate the size of Norway rat droppings, which can lead to misidentification and ineffective pest management efforts.
