What is a distinctive feature of house mice?

A house mouse typically weighs between 0.5 to 1 ounce, which is a key characteristic to identify this species. Understanding the weight range provides insight into the overall size and health of the mouse. This range is common for adult house mice, making it an important detail for pest control professionals when assessing and identifying potential infestations.

The other options, while they may contribute to identification features, do not capture the distinctive weight range that is specific to house mice. For instance, tail length, ear proportion, and belly fur color can overlap in characteristics with other mouse species or may not offer as definitive a guide for identification in practical pest control scenarios. Thus, recognizing the weight is crucial in distinguishing house mice from other rodent species in the field.
