Which evidence would not be included in a WDO inspection?

In a Wood-Destroying Organism (WDO) inspection, the primary focus is on evidence that indicates the presence of organisms that cause damage to wood, such as termites, wood-boring beetles, and fungi. Active termite infestations, termite droppings, and wood-eaten structural beams are all direct indicators of wood damage caused by such organisms and are critical to the inspection process.

Ambrosia beetle stains, while they may indicate the presence of wood-boring pests, do not provide direct evidence of active infestation or wood damage in the same way that droppings and structurally damaged wood do. Stains can be remnants of a past infestation or not indicative of current issues affecting the structural integrity of the wood. Therefore, these stains would not be included as compelling evidence in a WDO inspection, making it the correct choice. Understanding this distinction is crucial for identifying relevant evidence during an inspection.
