Termites cause more damage to Australian homes than fire, floods, and storms combined—and most of that damage is done long before the owner ever notices. In Sydney's warm, humid climate, subterranean termites can work silently inside walls for years.
The good news: with a few simple DIY checks, you can spot the early warning signs and act before the damage becomes costly. Here's how to inspect your own home and know when it's time to bring in a professional.
Important: DIY checks help you catch problems early, but they don't replace a professional inspection. Termites hide in places a homeowner simply can't reach safely.
Why Early Detection Matters
Termites—often called "white ants"—feed on the cellulose in timber. Because they eat wood from the inside out, a beam can look perfectly normal on the surface while being hollow within.
- Damage is usually not covered by home insurance.
- Repairs can run into tens of thousands of dollars.
- Colonies grow fast and spread to neighbouring structures.
Catching activity early is the single best way to protect your home's value.

DIY Termite Detection: Room-by-Room Checks
Set aside an hour, grab a torch and a flat-head screwdriver, and work through your home methodically.
1. Tap and Listen
Tap skirting boards, door frames, architraves, and timber beams with the screwdriver handle. A hollow or papery sound can mean termites have eaten the inside.
2. Probe Suspect Timber
Gently press the screwdriver into soft or damaged-looking wood. If it sinks in easily or reveals mud-packed galleries, that's a red flag.
3. Check for Mud Tubes
Look along foundations, brick piers, subfloor walls, and garden retaining walls for pencil-thin mud tubes—the highways termites build to travel from soil to timber.
4. Inspect Windows and Doors
Sticking doors and windows that suddenly won't close can signal moisture or termite activity warping the frame.
Early Warning Signs to Watch For
Beyond your hands-on checks, keep an eye out for these tell-tale signs throughout the year:
- Discarded wings near windowsills, light fittings, or doorways after warm evenings (swarmers shed wings).
- Mud tubes on walls, foundations, or trees.
- Hollow-sounding or sagging timber, floors, or skirting.
- Tight-fitting doors and windows or bubbling, cracked paint.
- Frass (droppings)—tiny pellets near drywood termite activity.
- Faint clicking sounds inside walls (soldiers banging their heads to warn the colony).

High-Risk Areas Around Sydney Homes
Termites are drawn to moisture and timber-to-soil contact. Pay extra attention to:
- Subfloors, crawl spaces, and damp basements.
- Bathrooms, kitchens, and laundries with hidden leaks.
- Garden beds, mulch, and timber sleepers touching the house.
- Stored firewood, timber, or cardboard against walls.
- Leaking gutters, downpipes, and air-conditioner overflow.
Common Confusions: Termites vs Ants
Many homeowners mistake flying termites for flying ants. The differences are easy to spot once you know them:
- Termites: straight antennae, broad waist, and two pairs of equal-length wings.
- Ants: elbowed antennae, pinched waist, and front wings longer than back wings.

When to Call a Professional
If your DIY check turns up any of the signs above—mud tubes, hollow timber, discarded wings, or live termites—stop probing and call a professional immediately. Disturbing an active colony can drive termites deeper and make treatment harder.
Even with no signs, Sydney homes should have a professional termite inspection at least once a year—more often in high-risk zones. Inspectors use moisture meters, thermal imaging, and movement sensors to find activity hidden behind walls.
