What is a common trait of nocturnal pests such as roaches?

Nocturnal pests, like roaches, are characterized by their activity patterns, which is primarily during the night. This behavior helps them avoid predators and allows them to seek food and water resources while minimizing competition and risk. Being active at night enables them to exploit environments that are less disturbed, allowing for greater foraging success.

Although some nocturnal pests may have preferences for warm places or certain environmental conditions, the defining characteristic that distinguishes them from diurnal pests is their nighttime activity. Attractiveness to light does not apply to roaches as they generally prefer dark, concealed areas. Hence, their nocturnal nature is a key aspect of their survival and behavior, making it the most relevant trait.
