Wood Borer
Common House Borer, prefers softwood/sap timbers, makes round exit holes from 2mm diameter. The frass from the borings is a densely packed fine powder. Beetles emerge from wood generally between November and February.
Two Tooth Long Horn Borer makes large oval holes measuring 3-4mm across. They attack sap or heart timbers. Beetles emerge during the Autumn. Frass is also fine and packed into their exit holes.
Termites
N.Z. Native Termites are wood-dwelling, they live in colonies hollowing out a cavity in the timber until it has only a thin layer on the outside, which makes it difficult to locate. However, a distinguishing feature is the presence of small, hard, oval six sided pallets of digested wood which are expelled from the runways. Affected timbers, if tapped, give a hollow sound and often show a wrinkled surface. This pest can cause major structural damage.
