Woodworm Symptoms & Causes

Woodworm is the wood-eating larvae of any of many species of beetle. It is also a generic description given to the infestation of a wooden item (normally part of a dwelling or the furniture in it) by these larvae.

The Signs Of Woodworm

Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces) around the holes. The size of the holes varies, but are typically 1mm to 1.5mm in diameter for the most common household species. Adult beetles which emerged from the wood may also be found in the summer months.

Typically the adult beetles lay eggs on, or just under the surface of, a wooden item. The resulting grubs then feed on the wooden item causing both structural and cosmetic damage, before pupating and hatching as beetles which then breed, lay eggs, and repeat the process causing further damage.

As the beetles evolved consuming dead wood in various forest habitats, most grubs, if not all, typically require that the wooden item contain a higher moisture content than is normally found in wooden items in a typical home.

As the name suggests they have a habit of borering deeply and leaving oval shaped tunnels and leaving soil like frass in its trails.

Powder Post Beetle

With a slightly hairy and reddish-brown colour this smaller beetle can still bore extensively deep in to young hardwood and known for following the grain, although this particular beetle creates a maze of conjuring tunnels resulting in a high level of damage.
Very easy to recognize by leaving flour like frass at the surface of its flight holes.

Bark Borer

This beetle comes in many varieties but most common are either dark brown or light brown colour.
Known most for targeting soft wood and causing major damage if left. Also common for the Bark Borer to fly locally to discover more timber sources.
