Which of the following would not indicate evidence of previous treatment during a Form 13645 inspection?

During a Form 13645 inspection, the presence of certain indicators can provide valuable insights into previous pest treatments. The correct answer, which identifies what would not indicate evidence of such treatments, is drill holes in a tree stump.

Drill holes in a tree stump do not necessarily signify that previous treatment was administered. They could be the result of other activities unrelated to pest control, such as routine arborist work or the natural process of the tree decaying. As such, they do not provide clear evidence of pest management interventions.

In contrast, the other options serve as more reliable indicators of past treatments. Visible vapor barriers can reflect preventive measures, often indicating that the area was treated for moisture or pest control purposes. Pest entry points can suggest areas that may have been targeted for pest exclusion or treatment. Treated wood decay would typically show that chemical treatments were applied to protect the wood from termites or decay fungi. Each of these elements points toward intentional actions taken to manage pest presence.

Understanding these indicators helps inspectors evaluate properties effectively and determine the history of pest management strategies used in the structure.
