Final answer:
Mud tubes, pellets, and live termites are all indicators of live termite infestation inside a house.
Step-by-step explanation:
The presence of mud tubes is a common indication of live infestation of termites inside a house. Termites build these tubes to travel from their nest to a food source, and they are usually found along foundation walls, plumbing, or electrical pipes.
The presence of pellets, also known as frass, is another sign of termite infestation. Termites produce tiny, pellet-like droppings as they feed on wood, and these droppings can accumulate near infested areas.
Infestation in exterior bait stations may indicate the presence of termites near the house, but it does not necessarily confirm an active infestation inside. Bait stations are designed to attract termites and be monitored for their presence.
The most direct and conclusive indication of live termite infestation inside a house is the presence of live termites themselves. If you see termites crawling around, it is a clear sign of an active infestation.
