In pest management, what does a higher population of roaches typically indicate?

A higher population of roaches typically indicates poor sanitation practices. Roaches thrive in environments where food and moisture are readily available. When there are unclean areas, leftover food particles, and standing water, it creates an inviting habitat for these pests. Therefore, observing a significant increase in the roach population often serves as a warning sign that the living conditions are conducive to pest infestations due to inadequate cleaning or sanitation.

In contrast, effective pest control measures would generally lead to a decrease in pest populations, not an increase. Seasonal changes can influence roach activity but would not cause a persistent higher population; instead, they may only cause fluctuations. Similarly, low building occupancy might reduce food sources for roaches, potentially leading to a decline rather than an increase in their population.
