Which sign may indicate a pest infestation?

The presence of pest activity reports from a licensed operator is a strong indication of a pest infestation. These reports are generated based on inspections conducted by trained professionals who know how to identify signs of pests. When these individuals document their findings, it provides valuable information about the presence and possible extent of an infestation, which can help ensure timely intervention and control measures.

In contrast, other options may not accurately reflect an infestation. The absence of food sources could suggest that pests are not feeding, but it doesn’t mean they aren’t present. Clean surfaces might indicate good hygiene practices, which help prevent infestations, but they do not prove that pests are absent. Fresh food containers can signify that food is being handled appropriately, yet they do not provide information about pest activity. Therefore, relying on professional assessments through reports is essential for understanding and addressing potential pest problems effectively.
