Termite Myths That Cost Sydney Homeowners Money

Most of the expensive termite mistakes I see start with a genuinely reasonable-sounding assumption that just happens to be wrong. Here are the ones that come up most often, and why they don't hold up.

Myth 1: Brick homes are safe from termites

Brick veneer doesn't stop termites, and even full-brick homes have timber somewhere, usually the roof trusses. The structural frame behind brickwork is timber, and termites reach it through weep holes, expansion joints, or the slab. The brick you can see has no bearing on what's happening in the frame behind it. I've written more on this in brick veneer and termite risk.

Myth 2: Only old houses get termites

Age matters less than conditions. A concrete slab isn't a termite barrier on its own, and new builds without proper pre-construction protection carry real risk too. What matters is whether the right barriers were installed at the right stage, and whether conducive conditions like moisture and timber-to-soil contact exist, not how old the building is. See are slab homes termite-proof.

Myth 3: If I can't see anything, I don't have termites

Termites feed from the inside of timber outward, leaving the surface intact, sometimes paper-thin, while the structural material behind it is compromised. Surface signs like sagging floors, blistering paint, or hollow-sounding timber tend to appear late, usually after real structural damage has already occurred. Absence of visible signs isn't the same as absence of termites.

Myth 4: A DIY spray will sort it out

A surface spray might kill the termites you can see, but it does nothing to the colony behind them, and disturbing an active colony this way can cause it to split and re-establish somewhere else in the house, a bigger problem than the one you started with. A proper treatment uses a non-repellent product that termites carry back to the colony themselves, so the whole colony is addressed, not just what's visible on the day.

Myth 5: Termites take a break in winter

Sydney's climate doesn't give termites a genuine off-season. Colonies live below ground where conditions stay comparatively stable, and foraging continues whenever soil temperature and moisture are sufficient, which in Sydney is most of the year. What's seasonal is swarming, not the colony's underlying activity. More on this in is it too cold for termites in winter.

Myth 6: A building inspection covers termites

A general building inspection and a termite and timber-pest inspection aren't the same scope. A termite-specific inspection covers termites, borers, and decay fungi specifically, using tools like thermal imaging and a moisture meter, rather than treating termite risk as one line item in a broader report. If you're relying on a combined building and pest report, it's worth checking exactly what was covered.

Why these myths cost money

Each of these assumptions leads to the same outcome: a delay. Delaying an inspection because the house is brick, or new, or because nothing's visible, or because it's winter, or because a general inspection already “covered it,” all give an established colony more time to do damage before anyone catches it. The cost of that delay is almost always higher than the cost of the inspection that would have caught it early.

Common questions

Which of these myths do you hear most often?
The brick one and the “nothing visible” one, by a wide margin. Both come from reasonable logic, brick looks solid, and no visible damage feels reassuring, but neither actually reflects how termites behave.

Does believing one of these myths mean I definitely have termites?
No. These are reasons people delay getting checked, not proof of an existing problem. Plenty of inspections find nothing that needs treating. The point is not to let an assumption be the reason you never find out either way.

I've heard termites only affect houses near bushland. Is that true?
Not specifically. Termite risk in Sydney is tied to conditions, moisture, timber-to-soil contact, housing age and construction, much more than proximity to bushland specifically. Properties across the whole service area can be affected.

How do I find out if any of these actually apply to my house?
An inspection is the only reliable way. I'll tell you honestly what I find, whether that confirms a risk or rules one out.
