Woodworm

The collective name for the larvae of wood-boring beetles - most commonly the Common Furniture Beetle (Anobium punctatum) - that tunnel through timber as they feed. Signs include small round exit holes (1–2 mm diameter), fine powdery frass, and in severe cases a crumbling surface. Active woodworm is treated by applying a permethrin-based insecticide to all exposed timber surfaces. Structural timber with heavy infestation should be assessed by a surveyor before a decision on retention or replacement.
