If evidence of rodent activity is found only on the second floor, what does this often suggest about the entry path?
Answer
The entry point is likely a vertical void like a pipe chase or unsealed wall cavity running upward
Finding evidence localized to an upper floor often suggests a direct vertical route from the exterior, such as a utility line or an unsealed void running straight up through the structure.
