If pest evidence is found but the origin is unclear, what should be done?

When pest evidence is found but the origin is unclear, asking construction questions to staff is a logical and systematic approach to identify potential entry points, conducive conditions, and previous pest issues. Engaging with staff who are familiar with the layout, repairs, and any structural changes can provide valuable insights. This information can help not only in pinpointing the source of the pest problem but also in assessing whether there may be ongoing vulnerabilities that need to be addressed.

Investigating the context around the pest evidence is crucial for developing an effective integrated pest management strategy. Understanding the building's history, maintenance schedules, and any alterations can lead to a more targeted and sustainable approach to pest control.

Meanwhile, other options may not effectively contribute to a long-term solution. For example, closing the facility outright can be excessive and disruptive without first gathering more information. Ignoring the evidence would risk a worsening infestation and related health risks. Initiating pest control measures without understanding the origin may lead to ineffective treatments and wasted resources. Thus, seeking insights from staff about construction and facility management stands out as the best initial step.
