Wood borers are one of the most misunderstood timber pests on the Gold Coast. Homeowners often confuse them with termites, and many don’t realise the damage until it’s too late. I’m Richard Eedy from Gold Coast Pest Inspector, and in this article I’ll tell you exactly what wood borers are, what to look for, and why a proper inspection matters.
Wood borers are the larval stage of various beetle species that lay their eggs in or on timber. When the eggs hatch, the larvae — the actual “borers” — tunnel through the wood, feeding on it as they go. This tunnelling can continue for months or years before the adult beetle emerges, leaving small, round exit holes in the timber surface. Those holes are often the first visible sign of an infestation.
The most common species found in Queensland homes include:
The tricky thing about wood borers is that the damage happens inside the timber where you can’t see it. By the time visible signs appear, the infestation may already be well established. Here’s what to look for:
The Gold Coast’s subtropical climate — warm, humid summers and mild winters — creates ideal conditions for wood borers. Timber in subfloors, roof voids, and older hardwood framing is particularly at risk.
Many Gold Coast homes built before the 1980s used untreated hardwoods and softwoods that are highly susceptible to borer attack. In newer homes, treated timber is used, but it’s not immune — especially if moisture has compromised the treatment over time.
People often confuse wood borers with termites, and the damage can look similar at first glance. Here are the key differences:
| Wood Borers | Termites | |
|---|---|---|
| Visible signs | Round exit holes, fine dust/frass | Mud tunnels, hollow timber |
| Speed of damage | Slower — can take years | Fast — can devastate in months |
| Timber preference | Dead, dry timber (sapwood) | Live timber and cellulose |
| Active signs | Rarely seen until adult emerges | Mud tubes, live insects visible |
Both are serious. Both require a qualified pest inspector to properly assess.
Earlier this year a buyer in Robina hired me to do a second opinion inspection before settlement. There was already a pest report from a building inspector — but that inspector hadn’t crawled into the sub-floor. I did. The wood borer damage I found was significant. The buyer pulled out of the sale and avoided a very expensive mistake.

If you’re buying a property on the Gold Coast, don’t rely on a building inspector’s pest report. Get a dedicated pest inspection from someone who will crawl into the sub-floor, get into the roof void, and check properly.
I’ve been doing this for years. I find what others miss.

Wood borers are wood-destroying insects whose larvae tunnel through timber as they feed and develop. Over time, they can weaken wooden structures, furniture, flooring, and other timber components if left untreated.
Common signs include small round exit holes in timber, fine powdery dust (frass) around wooden surfaces, weakened or damaged timber, and, in some cases, visible larvae or adult beetles emerging from the wood.
Yes. While damage often develops slowly, a long-term infestation can significantly weaken timber structures, flooring, roof timbers, and other wooden elements of a property. Early detection is essential to minimise repair costs.
Adult beetles lay eggs on or inside timber. Once the eggs hatch, the larvae bore into the wood and feed internally for months or even years before emerging as adults, leaving characteristic exit holes behind.
Wood borers typically leave small exit holes and fine powdery dust, while termites often create hollow timber, mud tubes, and hidden internal damage without visible holes. A professional inspection can accurately identify the pest responsible.
If you notice signs of wood borer activity, arrange a professional pest inspection as soon as possible. An experienced inspector can identify the species involved, assess the extent of the damage, and recommend the most effective treatment and prevention options.
