Which item would be considered a sign of pest infestation?

• A. Cluttered storage
• B. Clean floors
• C. Fresh air
• D. Gnawing damage

Answer: (D)

Signs of pest infestation include direct physical damage caused by pests. Gnawing damage is a clear indicator that pests, such as rodents or some insects, have been actively chewing on packaging, food containers, or structural materials, showing their presence and activity. This kind of damage prompts immediate corrective actions like removing affected items, sealing entry points, and implementing targeted pest control measures.

Cluttered storage, while it can create spaces for pests to hide, isn’t itself proof of an infestation. Clean floors reflect good sanitation practices but don’t indicate whether pests are present. Fresh air isn’t a sign of pests and doesn’t relate to infestation status.
