When are roaches most likely to be active, considering their nocturnal habits?

Roaches are primarily nocturnal insects, meaning they are most active during the night. This behavior allows them to search for food and water while avoiding predators and human activity. During the dark hours, they tend to roam and forage, making it easier for them to find shelter and resources without the risk of being disturbed.

In contrast, dawn and the afternoon do not align with their natural activity patterns, which is why those times are not when roaches are most likely to be seen. Being active all day is also inaccurate, as roaches typically rest and hide during daylight hours, emerging at night to engage in activities essential for their survival. Therefore, the correct choice reflects their well-documented behavior of being most active at night.
