Final answer:
During a termite inspection, live infestations can be identified through the presence of damage, pellets, and natural observation of live organisms.
Step-by-step explanation:
In a termite inspection, damage is considered a live infestation. When termites infest a structure, they can cause extensive damage to wood, including floors, walls, and furniture. The damage is evidence of an active termite colony, even if you don't see the termites themselves.
On the other hand, dead swarmers are not considered a live infestation. Swarmers are reproductive termites that emerge from the colony to mate and start new colonies. If you find dead swarmers, it could indicate that the mating process has already occurred, and the active infestation may no longer be present.
Pellets, also known as termite frass, are considered a sign of an infestation, but they do not indicate live termites. Pellets are tiny wood-colored droppings that termites leave behind. They are the result of termites eating wood and excreting waste.
Natural observation of live organisms is also a clear indication of a live infestation. If you see live termites in or around a structure, it confirms an active termite colony.
