There are 3 main species of Borers in Australia they are insects of dry wood, insects of moist wood and bark & wood damaging insects. Some borers are considered serious and some are not so serious. You need to make sure you know the difference between the two groups. Borers are bark & wood feeding insects & adult borers will lay their eggs in timbers. Borer larvae will feed on the timbers & sap. Whatever the situation is, you can always count upon our termite control in Western Suburbs which we are most equipped to provide at really affordable rates
Dry Wood Borers
Dry Wood borers are insects which will destroy all timbers which are naturally dry or decaying.
The species of the longicorns which have been introduced to Australia are originally from New Zealand and is a pest which attacks timber flooring and structural timbers. The Longicorns will often vary in size and is usually 12mm to 30mm. Longicorns are a brownish to reddish colour and will have an elongated body with dorsal spines on their thorax and they have large antennae’s. The female Longicorns will lay their eggs in cracks and crevices in wood surfaces. The larvae do not have legs and is more like a worm which will eat through the wood often leaving tiny holes where they have eaten.
The Lyctidae will attack sapwood which has enough starch as if it doesn’t have enough starch the larvae will not be able to feed and therefore will die.The Lyctidae will often vary in size often from 3mm to 6mm in length and is more like a flatten beetle which body is separated in to two segments. The Lyctidae are a brownish to reddish colour and have short antennae’s which are tucked in beneath its head. Lyctidae are often called powder post beetles and the larvae can spend months inside the wood eating it away until there is dust. The Lyctidae will mate outside of the timber at night and will deposit their eggs in flight holes.
Anobium Punctatum also known as the furniture beetle was introduced to Australia from Europe. The adult Anobium Punctatum does not feed on timbers and it is very rare that you will see an adult Anobium Punctatum. The female Anobium Punctatum will lay her eggs in cracks and crevices of timbers. The eggs will hatch a few weeks later and the larvae will be a creamy colour and look like a C-shaped. The larvae will live in the timbers for a few years by eating the starch in the timbers.
The Hylotrupes Bajulus is also known as the old house borer and is a beetle which will re-infests the same timbers that it has emerged from. The Hylotrupes Bajulus was introduced to Australia from Europe and despite its name the old house borer it is common to find the Hylotrupes Bajulus in newly built homes as the timber that is used often has larvae under the surface. The Hylotrupes Bajulus prefer to digest on pine and other sought of softwoods. Depending on conditions of the timbers the larvae can take up to 15 years to mature. The Hylotrupes Bajulus are a dark brown colour with four small whitish patches on the wings, their eyes are really shiny and are at the base of their antennae’s, their antennae’s are long and flowing. The Hylotrupes Bajulus are roughly 25mm to 30mm in length. The female Hylotrupes Bajulus will lay her eggs in cracks and crevices in timbers and once the larvae hatches it will destroy the sapwood.
Hadrobregmus Australiensis also known as the dampwood borer will attack both hardwood and softwood timbers. If the Hadrobregmus Australiensis attacks the timbers in your home not only will you need a chemical treatment but you will also need ventilation as the Hadrobregmus Australiensis needs high humidity in wood rot. The Hadrobregmus Australiensis is a dark grey to brown colour with its head concealed beneath the prothorax, they are roughly 7mm to 10mm in length. The female Hadrobregmus Australiensis will lay her eggs in cracks and crevices in timbers or wood.
Moist Wood Borers
Borers which attack moist wood are not always serious but can continue to eat until the timbers have dried out.
Ambrosia Beetles are part of the weevil family. They are also known as pinhole borers. Ambrosia Beetles will excavate tunnels in trees which have died or have wood rot. They will also attack timber skirting boards and furniture. Adult Ambrosia Beetles are roughly 1.7mm to 5.8mm in length with a cylindrical body, their head is well marked with black dull eyes and the Ambrosia Beetle has long skinny legs. The female Ambrosia Beetle will burrow deep into the timbers taking with a fungus like substance and will deposit her eggs. Once the eggs hatch into larvae the larvae will feed on the fungi which were left by the female Ambrosia Beetle. Once the wood starts to dry the Ambrosia Beetle will need to leave the timber otherwise they will die in the tunnels which they live in.
Jewel Beetles also known as the Buprestidae is a wood boring beetle and is over 15,000 species across the world. The Jewel Beetle gets its name from the beautiful glossy colour that they come in. The Jewel Beetle will often attack healthy trees and fresh logs which have fallen down. The three main species in Australia are Oregon Jewel Beetle, Cyprus Pine Jewel and Hoop Pine jewel Beetle.
The Oregon Jewel Beetle
Oregon Jewel Beetle better known as Buprestis Aurulenta ranges from 13mm to 2mm and is a glossy marble blue to green colour with cupreous margins on the elytra. Adult Oregon Jewel Beetles are attracted to trees that have been damaged and fresh tree stumps. The adult Oregon Jewel Beetle will lay her eggs in the cracks and crevices of these timbers. When the eggs hatch they will tunnel into the surface of the wood and can stay there up until 40 years.
Cyprus Pine Jewel
The Cyprus Pine Jewel beetle is roughly 15mm to 20mm long in a flat cylinder shape body it has short toothed antennae’s, the Cyprus Pine Jewel can vary in colour often a bright yellow or green colour. They can sometimes have little patches or spots on the elytra. The larvae will tunnel until the surface of the wood and can live up to 20 years.
Hoop Pine jewel Beetle
The Hoop Pine jewel Beetle also known as Prospheres Aurantiopictus are 13mm to 19mm in length and their body is flatten with serrated antennae’s, the Hoop Pine jewel Beetle will vary in colour. Hoop Pine jewel Beetle will emerge from hoop pine up to 15 years after the timber has been utilised. The Hoop Pine jewel Beetle larvae will tunnel throughout the wood often staying just below the surface.
Bostrychid Wood borers
Bostrychid Wood borers which are sometimes referred to as Auger Beetlesusually don’t attack healthy trees but rather branches and other debris from the tree, the only time they will attack a healthy tree is in flight season which is usually around spring. Bostrychid Wood borers do not reinfest dry wood as they need some moisture in the wood to be able to breed and will live till around 12 months. The adult Bostrychid Wood borers are roughly 5mm to 20mm in length and they are a goldish to darkish brown colour with long antennae’s. The Bostrychid Wood borers lay their eggs just beneath the surface of the wood. Once the larvae have hatched they will tunnel their way through the wood often leaving frass.
There are many species of the Longicorns but the one that is native to Australia and the one that does the most damage are the Phoracantha Semipunctata and solely attacks eucalyptus trees. They have a life span of 2 to 3 years and have an elongated body with long antennae’s. The Longicorn is brownish in colour with a creamish to orangish band across their back. The Longicorn will lay its eggs in the damaged part of the tree to where once hatched into larvae will feed on the sapwood.
