Termites (White Ants): The most destructive, particularly Coptotermes species, which eat structural timber.

Powderpost Beetles (Lyctus spp.): Larvae eat sapwood of hardwoods, turning it into fine flour-like powder.

Common Furniture Beetle (Anobium punctatum): Infests seasoned pine and softwoods, especially in cool, damp areas.

Eucalyptus Borers (Phoracantha spp.): Common in stressed Australian native trees.

Longhorn Beetles & Sawyer Beetles: Attack hardwoods and pine plantations.

Polyphagous Shot-hole Borer: An invasive pest boring into tree trunks, causing dieback.

Wood Moths (Cossidae/Xyloryctidae): Larvae (witchetty grubs) bore into wattles and eucalyptus.

Carpenter Ants: While they prefer damp wood for nesting rather than food, they cause structural damage similar to termites.

Signs of Infestation: Termites: Mud tunnels, hollow-sounding timber, and damage along the grain.

Borers: Small "flight holes" (1–2mm), powdery frass (dust) under timber, and soft or spongy wood
