The Difference Between Borers & Termites
When Sydney homeowners think of timber pests, termites immediately come to mind. But there is another silent destroyer that could be eating the structural framing of your home right now: the wood borer.
While both pests destroy timber, their habits, the damage they cause, and the way we treat them are entirely different.
What is a Borer?
A wood borer is an insect (typically a beetle) that lays its eggs in the cracks and crevices of timber. When the larvae hatch, they burrow deep into the wood, feeding on the starch and cellulose for months—or even years—before emerging as adult beetles to start the cycle again.
The most common culprit in Australian homes is the Anobium Borer (Furniture Beetle), which loves the soft pine timber often used in older floorboards and roof framing.
Borers vs. Termites: Spotting the Difference
- The Damage: Termites hollow out the inside of the wood, leaving a paper-thin veneer on the outside. You can often push your finger straight through termite-damaged wood. Borers, on the other hand, leave the wood looking like a honeycomb, covered in tiny, perfectly round “flight holes” (about 1-2mm wide).
- The Evidence: Termites build mud tubes to travel safely. Borers leave behind “frass”—a fine, powdery dust that looks like flour, which gets pushed out of the flight holes as they tunnel.
Is It Active?
Just because you see borer holes doesn’t mean the infestation is active; the beetles may have vacated years ago. During a professional pest inspection, we check for fresh frass and live adult beetles to determine if treatment is immediately required.
