What beetles make a scratching sound in wood?

Wood-boring beetles, particularly the larvae of species like the powderpost beetle and the wood-boring beetle (from the family Buprestidae), are known to make a scratching sound in wood. As they tunnel through the wood, they create friction which produces this characteristic noise. The sound is often more pronounced in older or damaged wood where the beetles have established their galleries. This scratching can indicate an infestation, making it a concern for wood structures and furniture.
