Repairing the damage
Wait for confirmation that the colony is dead before repairing anything. Pull out the timber too soon and you remove what they were feeding on. Get a builder to assess the structural members - bearers, studs, roof timbers.

LOCAL COVERAGE
Termite Control in Thornleigh
What we cover in Thornleigh, and how quickly we can get there.
Thornleigh sits about 19.6 km north-west of the CBD in the Ryde & the Northern District, and postcode 2120 is one we are in most weeks. We run Thornleigh on a regular route, and same-day attendance is usually available.
If you are near Brickpit Park, Thornleigh Marketplace or Westleigh Shopping Village, that is ground we cover constantly - it is the busiest part of Thornleigh for us.
Our runs through Thornleigh also take in Normanhurst, Westleigh and Pennant Hills. The building stock is close-packed, so we look at what the property adjoins before deciding where product goes.
Most Thornleigh bookings come in as terraces and semis where the problem has come through a shared wall. Say which one applies when you call 1300 313 373 and the technician will have the right products on the van.
We cover the remainder of 2120 as well, from Thornleigh station through to Normanhurst station.
We confirm your slot the day before and arrive at a stated time. Normanhurst and Westleigh sit on the same run, so earlier appointments in 2120 come up regularly.

OVERVIEW
Termite Control That Targets the Colony in Thornleigh
Alates look like flying ants. The giveaway is the wings: termite wings are all the same length and shed in piles, ant wings are not. Finding them in a Thornleigh house means a mature colony nearby.
We have found colonies feeding on skirting boards, wardrobe carcasses, stored books and the paper face of plasterboard in Thornleigh houses. Structural timber is the worst outcome, not the only target.
Subterranean termites must stay in contact with soil moisture, so they build pencil-width mud tubes to carry it with them. On a Thornleigh pier, slab edge or internal wall, those tubes are the most reliable sign there is.
- Nothing gets treated until the species and the activity are confirmed
- Baiting, soil barrier or a combination
- Products used and areas treated, recorded in writing
- Warranty terms set out in writing alongside the quote
HOW WE TREAT
Termite Treatment Methods We Use in Thornleigh
Photos from our own Sydney termite jobs. Most properties need one primary method, and some need two working together.
In-Ground Baiting Systems
Soil stations placed around the footings. The timber inside draws termites in, bait replaces it, and the nest is destroyed by the workers' own foraging.
Station Checks & Refills
Stations are opened on a schedule to check for feeding and top up bait. Missed checks are a common reason baiting programs stall.
Above-Ground Bait Placement
If there is active work inside a wall or architrave, we can mount bait straight onto it, which puts the colony onto bait immediately rather than waiting for them to find a station.
Chemical Soil Barrier
We trench along the footings and apply termiticide, drilling and injecting through paths and slabs where trenching is not possible, so the treated zone is continuous.
Subfloor & Pier Treatment
With a suspended floor the piers and wall lines are part of the job. Most concealed termite activity we find started under the house.
Damage Assessment
We walk you through the damaged timber and record it for your builder. Repairs come after elimination is confirmed, not before.
FOUND TERMITES?
What to Do Before We Arrive in Thornleigh
What you do in the first day or two affects how quickly the colony can be eliminated.
Don't Spray Them
A can of spray takes out the ones you can see and sends the rest away from that spot - which removes the one place bait could have reached them.
Don't Break Open the Workings
Mud tubes and eaten timber are best left alone. Open them up and they dry out, the termites withdraw, and the treatment takes longer.
Take Photos
Take pictures of anything you have seen and remember where. It tells us what to bring and where to start.
Look for Moisture
Moisture is usually part of the story: a leaking tap, the hot water overflow, the air conditioner condensate line. Damp soil pulls termites in, so it needs fixing too.
Book Promptly
Subterranean termites feed continuously, so waiting costs timber. Same-day and next-day inspections are available right across Sydney.
Tell Your Strata Manager
In a unit or townhouse, activity in one lot often involves common property, so let the strata manager know early.

WHY IT MATTERS
Baiting vs Soil Barrier: Which Treatment Fits?
Both are recognised approaches for existing buildings under AS 3660.2. The right choice depends on your property.
| Consideration | Baiting system | Chemical soil barrier | Combination |
|---|---|---|---|
| Purpose | Elimination of the colony feeding on the structure | A treated band of soil that affects termites travelling through it | Both: the active colony goes, and new ones are deterred |
| Method of install | Soil stations round the perimeter and bait onto the workings themselves | Trenching at the footings with drilling and injection through hard surfaces | Bait phase first, soil barrier second |
| How intrusive it is | Low. Nothing drilled, nothing dug out of the garden | Paving gets small drill holes which are then sealed, and gardens get trenched | Spread over staged visits rather than one disruptive day |
| Ongoing maintenance | Regular scheduled station checks, which double as ongoing monitoring | How long it lasts comes down to the product label and the site, and it can be re-applied | The station checks carry on while the barrier does its job |
| Typically chosen for | Active termites, sites under extensive paving, or where chemical input must be minimised | Properties where there is good access to the soil at the footings | Heavy activity, a history of attacks, or a high-risk bushland block |

OUR PROCESS
From Live Termites to a Protected Home in Thornleigh
Termite treatment is a program over several visits, not a one-off spray.
01
Confirm Species & Extent
We identify the termites, trace mud tubes and workings, and check the roof void, subfloor and garden for the likely nest and entry points.
02
Written Treatment Plan
Everything goes in writing before we start - method, treatment areas, products and the follow-up schedule - at a fixed price.
03
Treat the Active Colony
Treatment goes where the termites actually are - bait on the workings or in stations, or termiticide in the travelled soil.
04
Monitor Until Elimination
Monitoring runs until elimination: each visit records feeding and replenishes bait. Bigger colonies and cooler months take longer.
05
Protect the Building
With the colony eliminated, the next question is protection - a soil barrier, continued station monitoring, or both together.
06
Records & Next Inspection
A written record of every product and location, and a date for the next timber pest inspection.
PRICING
What Termite Treatment Costs Depend On in Thornleigh
Treatment starts from $179. Your fixed quote comes after we've seen the activity.
| Factor | Why it changes the price |
|---|---|
| Location of the activity | Termites confined to one architrave take far less work than activity running through a subfloor and the wall framing |
| Method chosen | Above-ground baiting, in-ground stations and full soil barriers use different amounts of product and labour |
| Access and perimeter | Long footings, restricted subfloor height and narrow passages down the side all add labour |
| Concrete & paving | Paths, patios and garage slabs that must be drilled and injected take longer than open soil |
| Number of follow-ups | Return visits carry on until the colony is gone - larger colonies take more of them |
| What sort of property | A strata block, a commercial site or a house with an extension or granny flat is quoted individually |

AFTER TREATMENT
Life After a Termite Treatment in Thornleigh
Living with bait stations
You will have in-ground stations sitting flush with locking lids. Keep them clear of mulch and concrete, leave them in place, and call before landscaping so we can relocate them.
Looking after a soil barrier
The barrier depends on the soil staying put. Garden beds, pavers and decks built against the house are the usual way one gets broken, so talk to us before the work.
- Soil and mulch stay below the line of the weep holes
- Don't stack timber against walls
- Fix leaks near the footings
Keeping watch
AS 3660.2 sets the baseline at inspections every 12 months or better, more often on high-risk sites. A regular inspection is the only thing that catches a new attack early.
RISK FACTORS
Conditions That Invite Termites Back in Thornleigh
Treatment removes the colony. These property conditions attract the next one, and most are cheap to fix.
- Garden beds or mulch built up against the house, hiding the slab edge
- Leaking taps, downpipes or hot water overflow pipes near the footings
- Condensate from the air conditioner dripping into soil beside the house
- Leftover stumps, railway sleepers or timber scraps in the yard
- Fence or pergola posts, and steps, bedded directly into the ground
- Brick weep holes that have been rendered across or blocked
- Poor subfloor ventilation and damp soil under the house
- Firewood and leftover materials stored against the house wall
- Extensions or decks added without joining up termite protection
- A timber retaining wall near the building
SYDNEY TERMITES
Why Sydney Homes Get Attacked in Thornleigh
Risk is partly about the street, not just the building. Old stumps, timber fences and untreated structures nearby all sustain colonies within foraging distance of a Thornleigh home.
Around Thornleigh the risk is driven by what is in the soil and what the house is made of. Timber-framed homes with gardens against the slab edge are the ones we find activity in most often.
Nasutitermes is common in gardens around Thornleigh and far less destructive than Coptotermes. Knowing which you have is the difference between urgent and manageable.

FAQ
Termite Control Questions, Answered
Everything you need to know before you book. Still unsure? Call us — we're happy to help.
Get a Free QuoteHow much does termite control cost in Thornleigh?
Termite treatment starts from $179 and a full timber pest inspection from $159. The fixed price depends on the size of the property and how far the problem has spread, and we confirm it before we start - there is no call-out fee in Thornleigh 2120. Treatments carry a 6-month warranty and we re-inspect annually.
What is the wait for a technician in Thornleigh?
Same-day attendance is usually available. Our Ryde & the Northern District technicians cover Thornleigh daily, and you get a confirmed arrival time when you book.
Why are termites such a problem in Thornleigh?
Two things stack up here: shared structure and old drainage. Either one on its own is manageable; together they are why termites in this kind of housing is a street-level problem.
What kind of buildings do you work on around Thornleigh?
Mostly terrace and semi. We look at the party wall, the sub-floor and the roof space, because those are the routes between houses.
Do you work with agents and strata managers in Thornleigh?
We do. A lot of our Thornleigh work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
Is the treatment safe around children and pets?
Yes. Everything we use is registered for the purpose and applied at label rates, and we place product where people and animals do not go. Tell us about pets, aquariums or anyone with a respiratory condition at booking.
Do I need to leave the property during treatment?
Generally no. We will tell you on arrival if any part of the job means keeping out of a room for a while, so there are no surprises.
How much time should I allow?
Allow one to two hours for a typical Thornleigh property. Larger homes, or ones where the problem has spread, take longer and we will say so when we quote.
What if the termites come back?
Treatments carry a 6-month warranty and we re-inspect annually. Ring us if activity picks up again inside that period and we will arrange the return.
Do you cover the suburbs around Thornleigh too?
Yes. As well as Thornleigh we cover Normanhurst, Westleigh, Pennant Hills and Wahroonga on the same runs, so a job that crosses a boundary can be handled in one visit.
