Why Hornsby properties get termites
Hornsby's bushland fringe, established gardens and older brick-and-timber homes make it one of Sydney's highest termite-risk postcodes. Rodent pressure spikes in autumn as mice move indoors from the surrounding reserves.
Around Hornsby Westfield, older subfloors, garden beds built up against slab edges, leaking taps and air-conditioning overflows, timber retaining walls and stored firewood all give subterranean termites the moisture and concealed access they need. Colonies can forage up to 100 metres, so a nest in a neighbouring yard or street tree in 2077 is still your problem. Most Hornsby homes should be inspected at least every 12 months.
Termite inspections in Hornsby
Every job starts with a full AS 3660 timber pest inspection — interior, roof void, subfloor, perimeter, fences, trees, garden beds and outbuildings — with a written report, photos and a risk rating you can act on.
Standard timber pest inspection
Full property inspection with moisture readings, sounding of timbers and a written AS 3660 report emailed the same day.
Thermal imaging inspection
Thermal cameras detect heat and moisture signatures of live termites inside walls without cutting anything open.
Moisture & movement detection
Moisture meters and microwave movement detectors confirm activity behind plaster, tiles and brickwork.
Pre-purchase inspection
Buying in Hornsby? Fast turnaround reports timed around auction and cooling-off deadlines.
Annual inspection reminders
We track your inspection cycle and remind you when the next one is due so warranties stay valid.
Post-treatment verification
Follow-up inspections after treatment to confirm the colony is gone before we sign the job off.
Termite treatments in Hornsby
Treatment is chosen around how the termites are entering and how your property is built — slab-on-ground, subfloor, brick veneer or a renovated mix of all three.
Colony elimination (non-repellent)
Non-repellent liquid applied to active workings and entry points. Termites can't detect it and carry it back through the colony.
Termite dusting
A fine transfer dust puffed directly into live workings. Foragers groom it onto nestmates, taking the colony down without disturbing the mud leads.
Foam & void injection
Expanding foam injected into wall cavities, architraves and voids where liquid can't reach.
Direct nest treatment
Where a nest is located in a stump, tree or wall cavity, we treat it directly for the fastest result.
Emergency response
Live termites eating your Hornsby home? Priority attendance, including same-day where a slot is available.
Damage assessment
Advice on structural damage, what needs replacing and how to sequence repairs safely after treatment.
Termite baiting & monitoring in Hornsby
Baiting suits properties where activity is intermittent, where a full chemical barrier isn't practical, or where you want an early-warning system left in the ground permanently.
In-ground bait stations
Stations installed at intervals around the property, checked on a set schedule until the colony is eliminated.
Above-ground stations
Fitted directly over active workings indoors so foragers feed without needing to be located outside.
Ongoing monitoring
Once the colony is gone, stations stay in place as an early-warning system for the next attack.
Documented service records
Every station visit logged and reported — important for warranties, strata and pre-sale files.
Barriers & reticulation systems for Hornsby homes
A treated zone or physical barrier is what stops the next colony. Existing homes usually get a perimeter treated zone or a retrofitted reticulation loop; new builds and extensions get a pre-construction system installed at slab stage under AS 3660.1.
Perimeter treated zone
A continuous treated soil zone around the building so any new attack must pass through the chemical.
Reticulation refill
Where a reticulation system exists, we recharge it on schedule through the refill points to keep the barrier live.
Physical barriers
Kordon, HomeGuard, Trithor and TermSeal products installed at penetrations, perimeters and pipe collars.
Pre-construction systems
Full under-slab and perimeter systems specified and installed at the right stage of the build, with certificates.

Termite signs & help — what to do in Hornsby
Found live termites? Don't spray them and don't break the mud leads. Disturbing a working scatters the colony and makes elimination far harder. Cover it, leave it alone and call 1800 733 222.
NSW Government also publishes homeowner guidance — how to check for termites.

Termite control Hornsby — FAQs
How much does a termite inspection cost in Hornsby?
A full AS 3660 timber pest inspection for a standard home in Hornsby 2077 generally starts around $280–$390 depending on size, subfloor access and whether thermal imaging is required. You get a written report with photos, a risk rating and a clear treatment recommendation.
How often should Hornsby homes be inspected for termites?
Australian Standard AS 3660.2 recommends a competent inspection at least every 12 months. In Hornsby, properties near bushland, creeks, older subfloors or with previous activity should be inspected every 6 months.
What are the signs of termites in a Hornsby property?
Mud leads on piers and walls, hollow or drummy skirting boards, blistered paint, tight-fitting doors, frass near timber, discarded wings after rain, and damp musty smells in the subfloor. Around Hornsby Westfield, timber retaining walls, garden beds against slab edges and stored firewood are common starting points.
Do you treat live termites the same day in Hornsby?
Where a job slot is available we attend Hornsby the same or next day for live activity. Do not spray or disturb the termites — that scatters the colony. Call 1800 733 222 and we will talk you through protecting the area until we arrive.
Is termite dusting or baiting better?
Dusting is ideal where there is accessible live activity and we want fast colony transfer without disturbing the workings. Baiting suits properties where activity is intermittent, or where a chemical barrier isn't practical. Many Hornsby jobs use dusting first, then baiting or a barrier for long-term protection.
Do I need a pre-construction termite system in Hornsby?
Yes — every new build, extension or slab in NSW requires a compliant termite management system under AS 3660.1. We install reticulation and physical barrier systems including Termguard, Altis, TermX, TermStop, Kordon, HomeGuard, Trithor, TermSeal and GreenZone.
