Which wood destroying insect causes damage in soft areas of wood and doesn't follow the grain?

Carpenter ants are known for their unique behavior when it comes to nesting and feeding on wood. Unlike termites, which consume wood and can follow the grain as they eat, carpenter ants prefer to excavate wood to create their nests. The damage they cause typically appears in soft or decaying areas of wood where they tunnel, often creating smooth, sanded surfaces rather than the jagged edges seen with other wood-destroying insects.

The distinction of not following the grain is significant because it indicates a different method of wood interaction. Carpenter ants do not consume the wood as termites do but rather remove it to create their colonies, leaving behind a hollowed-out structure that can be identified by the presence of frass (sawdust) and exit holes. This tunneling behavior leads to soft areas in wood structures, which can lead to significant damage over time. Understanding the specific behaviors and damage patterns of carpenter ants is essential for effective pest management and control strategies.
