What is considered the most definitive sign of an active rodent infestation?

• A. Seeing a live rodent
• B. Damage to foods
• C. Rodent feces on the floor
• D. Rub marks on walls

Answer: (A)

Direct evidence of active presence is strongest when you actually see a live rodent. This confirms ongoing activity and the immediate risk to food safety and health. Indirect signs—like damage to foods, droppings, or rub marks—show rodents have been around, but they can reflect past activity or lingering effects rather than current infestation. A live sighting leaves little doubt that the infestation is active and requires prompt, targeted control measures.
