Termite Evidences vs. Termite Signs
Termite evidences is different from Termite signs.
Termites live inside the wood member in case of drywood termites and deep in soil and inside the wood member in case of subterranean termites. This is why detecting actual live termites consuming the wood in structures is rarely the case since they are not readily visible.
Termite evidence is when live drywood or subterranean termites are found within or close to the structure.
Termite signs are not termites themselves but signs of them such as drywood termite droppings in form of pullets, wings, damaged wood, as well as subterranean termite mud tubes, winds and other signs.
It is important to realize that non-existence of termite signs does not necessarily mean there are no termites in inaccessible and invisible and even in visible and accessible wood members.
This is simply due to the fact that if a wood member is checked and no termite signs are found, it does not mean there will be no termite infestation there. Termite infestation may be new and no droppings may be found. Also, the wood members inspected may be eaten by termites from inside, and it will not show during inspection.
