Some borers will not cause lasting or structural damage. However, even if this is the case, professional chemical treatments are available. Depending on the extent of the damage, this can be a one-off, or take place over a few treatments. Call us on or book online. Read more. Your email address will not be published.

How do I identify wood borers? The most important questions to answer are: What type of borer is responsible? How bad is the damage? Are the borers still active? Fully-grown larvae tunnel towards the surface and create oval cells within which they pupate.
Mature beetles emerge after weeks through circular holes mm diameter , creating small piles of frass on the timber surface.
Re-infestation is common for up to five years after tree-felling, until the food resource is depleted. Damage Powderpost and all Lyctine beetles attack only the sapwood of certain hardwoods and do not attack softwoods.
Susceptible timbers must contain enough starch to nourish the developing larvae. The heartwood is never infested, although adults may emerge through it. Most infestations occur in logs or sawn timbers drying at the saw-mill. Infestation may not be noticed until the timber is in-service and adults begin to emerge.
Infested timber contains galleries packed with fine, powdery frass. The infested area may be reduced to powder within a shell of wood, perforated by emergence holes. Small piles of smooth, floury frass may be found outside the timber. Infestation may occur anywhere where susceptible timber has been used for example, in subfloor areas, living space, roof space, or in furniture and artefacts. In new houses, emergence holes may appear in the lining materials for example, in plasterboard and paneling and joinery.
Such holes are made by adults emerging from the hardwood framing beneath. The Queensland pine beetle is a small native beetle and a pest of hoop pine timbers. There are about species of Anobiid beetles Family Anobiidae world-wide, but only about of these occur in Australia.
In Queensland, four species of Anobiid may be found in or around buildings. The Queensland pine beetle and the common furniture beetle, a native of Europe, are of economic significance, while the pine bark Anobiid and the cigarette beetle are of minor importance. Changes to building practices have decreased the risk of attack to timber-in-service and reports of damage have become less frequent. Scientific Name Calymmaderus Incisus.
Description The adult beetle is oval in shape, about 3mm long, 1. The antennae terminate in a three-segmented club. The body surface is covered in fine hairs and numerous minute punctures, which are not discernible to the eye. The legs can be tightly folded against the body. The eggs are white, spherical, 0. The larva is soft-bodied, clothed with numerous fine hairs, curved, wrinkled, and creamy white with dark-brown mandibles. When fully grown the larva measures mm in length and 1.
The pupa is soft, oval, creamy-white and measures 3. Distribution It is a small native beetle widespread in south-eastern Queensland. Previously, it has caused significant damage to timbers only within the area limited by Murwillumbah New South Wales in the south, Bundaberg in the north and west to the Great Dividing Range. Eggs are laid in cracks of susceptible timber and larvae hatch in a few weeks. Larvae can burrow long distances in the host timber and only the larval stage is responsible for destruction of timber.
Tunnels run with and across the grain, giving a honey-combed appearance. The tunnel is loosely packed with frass, which, if viewed under a lens, is seen to consist of cigar-shaped pellets made up of the chewed wood. When rubbed into the palm of the hand, the frass is fine and gritty, quite distinguishable from the frass of the powderpost beetle, Lyctus , which is soft and silky. Frass is sometimes ejected in small amounts through flight holes. Before pupating, the larva moves closer to the surface and constructs a pupal chamber.
The development period for larvae is usually three years. Mature larvae pupate and adults emerge leaving a circular 2 mm hole in the timber surface. Painted surfaces or wall sheeting materials may be penetrated during emergence.
It is a very slow working insect that may take many years to cause extensive damage. Damage To Timber Queensland pine beetle is a pest of susceptible hoop pine sapwood and rarely attacks other timbers. It attacks exposed without paint or varnish finish , susceptible wood in housing and, less commonly, in furniture.
Attack is most serious in old homes of more densely populated areas. Service Master Branches are located across the entirety of South Africa.
