What is a sign that indicates a raccoon may be using an area?

A sign that indicates a raccoon may be using an area is the presence of overturned garbage containers. Raccoons are opportunistic feeders and are known to scavenge in urban environments, especially at night. When they rummage through trash cans, they can easily knock them over in search of food. This behavior is a clear indication of their presence in the vicinity.

Additionally, nocturnal activity is also a significant indicator of raccoon presence. Raccoons are primarily active during the night, and observing them or signs of their activity, such as noise or movement at night, can suggest that they are inhabiting the area. Furthermore, excessive daytime activity can also be a sign, as it may indicate that the raccoons are feeling comfortable in the area or that food sources are plentiful, which is unusual behavior for this typically nocturnal species.

Considering all of these points, the correct answer incorporates all relevant signs, affirming that the presence of overturned garbage containers, nocturnal activity, and excessive daytime activity collectively signal raccoon usage of an area.
