Which insect hollows out wood for shelter and leaves piles of sawdust at the base of poles?

Explanation:
Carpenter ants hollow out wood to create nesting galleries, so they’ll often push out a coarse, sawdust-like material known as frass. When they excavate inside a pole or post, that frass accumulates as piles around the entrance, especially at the base. This combination of hollowed wood and visible sawdust-like frass is a telltale sign of carpenter-ant activity. Termites would show different signs, such as mud tubes or a fine, pellet-like frass produced by drywood termites, and beetles or fungi don’t produce the same distinctive frass piles at the base of poles. So the described behavior matches carpenter ants best.
