Which insect activity is evidenced by piles of sawdust at the base of poles and hollowing wood for shelter?

Explanation:
Carpenter ants hollow wood to create nesting galleries and push out coarse, sawdust-like frass as they excavate. That frass often accumulates at the base of affected wooden poles, signaling an active nest inside. The combination of hollowed, tunneled wood and visible piles of wood shavings is a classic sign of carpenter ants. Termites usually leave mud tubes and different-looking frass, while wood borers and beetles tend to leave fine powder or pellets from smaller, localized bore holes rather than large, hollowed galleries.
