Wood-destroying insects

Wood Boring Beetles

Multiple beetle families

Beetles whose larvae tunnel through timber, furniture or structural wood while developing.

Included in this category

Powder post beetle (Lyctus brunneus)

Adults differ by species, while pale curved larvae live inside wood. Exit-hole size and frass texture help identify the group.

Larvae may remain concealed for months or years, feeding along the grain before adults emerge through characteristic holes.

Larvae feed on starches or cellulose in seasoned, damp or decaying timber according to species.

Adults lay eggs on rough timber, cracks or old exit holes. Larvae bore into the wood and later pupate near the surface.

Fresh exit holes, powdery or pellet-like frass, weak timber, audible feeding in severe cases and adult beetles near windows.

Persistent attack can damage furniture, artefacts, flooring and structural timber.

Prevention

Confirm the organism before selecting control measures

Remove food, water and shelter where practical

Seal or manage access points and harbourage

Use monitoring and a site-specific IPM programme

Professional support

Arrange a site-specific assessment with PCAMB.
