When conducting a rodent inspection, which of the following is the BEST indicator of an active infestation versus an old one?
1
Fresh, moist, dark-colored droppings in the area
✓ Correct Answer
2
Finding a dead rodent in a snap trap that was set previously
3
The presence of any droppings regardless of their condition
4
Visible grease marks along walls and pipes
Explanation
Fresh rodent droppings are soft, moist, and dark; old droppings are hard, dry, and gray. Fresh droppings indicate current activity in that area. Gnaw marks can be old or new (fresh gnaw marks are lighter in color). Runways and rub marks build over time. Droppings are the most reliable indicator of recent activity.
