Which of the following factors is crucial in pest management in food storage areas?

In pest management, particularly within food storage areas, finding and removing the source of pests is a fundamental strategy. This practice directly addresses the root cause of pest infestations. By identifying and eliminating the sources—such as food spills, hidden food caches, or cluttered storage conditions—pest populations can be significantly reduced or entirely eradicated.

When food sources for pests are removed, it not only limits their ability to reproduce but also encourages pests to leave the area in search of alternative sustenance. This proactive approach is essential for long-term management of pests and is a cornerstone of integrated pest management (IPM) practices.

Other factors such as labeling food items, temperature control, and organic pesticide use play important roles in an overall pest management strategy, but they do not directly address the initial cause of the infestation, which is why they are not considered as crucial as finding and removing the source. For instance, while temperature control can deter pest activity following infestation, it does not eliminate current populations or prevent future infestations unless coupled with measures that target the source.
