When conducting a home inspection, identifying signs of pest infestation is crucial to assessing the property's condition. The presence of droppings, holes in walls, or damage to wood structures is particularly significant because these indicators are directly associated with various types of pests. For example, droppings may suggest the presence of rodents, while holes in walls can indicate entry points for pests like termites or even larger rodents. Damage to wood structures, such as termites consuming the wood, is a clear sign that a pest issue is present and needs to be addressed promptly.

Other options, while they can suggest issues that may require further investigation, do not directly correlate with pest infestations. For instance, outdated appliances might indicate a need for modernization of the home but do not provide evidence of pest activity. Unusual odors can stem from various sources, such as plumbing issues or mold, and while they might signal a concern, they do not specifically point to pest infestation without further evidence. Noise from the attic or basement might suggest animal activity, but it is not as clear-cut as the specific signs of droppings, holes, or structural damage, which are well-documented indicators of pests. Thus, option B is the most definitive sign of a pest infestation during a home inspection
