Termite treatment in Sydney starts with a licensed timber pest inspection, then a spot treatment, chemical barrier or baiting system matched to what the inspector finds. In Sydney, an inspection typically costs $345, spot treatment $575, a baiting system $3,000 and a chemical barrier $4,025. If you suspect termites, leave the area undisturbed and book an inspection before anything else.
Key points
- A Sydney termite inspection costs $290–$575 (typical $345), and most inspectors recommend one every year.
- Never disturb active termites or spray a live nest yourself, because it can scatter the colony and hide the damage.
- Treatment choices are spot treatment, a chemical barrier or a baiting system, and the right one depends on the inspection findings.
- The technician must hold an NSW pest management technician licence; ask to see a copy before work starts.
When you need termite treatment in Sydney homes depend on
- Mud tubes on walls or in subfloors: pencil-width tunnels up brick or concrete show termites travelling to timber, often tracking up through garden beds against brick walls. See early warning signs of termites.
- Hollow-sounding timber: skirting boards, door frames or floors that sound papery when tapped may have been eaten from the inside while the paint looks intact.
- Flying termites after warm rain: a swarm of winged insects near a window or light can signal a nearby nest; compare them with what termites look like.
- Frass or tiny pellets: small piles of wood-coloured pellets under timber mean activity, and our guide to termite frass shows examples.
- Buying or selling a home: a pre-purchase inspection reveals hidden activity, and an unchecked house can hold costly damage.
- Time since your last check: most inspectors recommend an inspection every year, even if you have never seen a termite.
What termite pest control includes
| Job type | What we do | When it suits |
|---|---|---|
| Termite inspection | A licensed inspector checks the roof void, subfloor and exterior against AS 4349.3 and reports on activity and risk | Annual checks, pre-purchase and any suspicious sign |
| Spot treatment | Treat a small, confined area of activity with registered products | Limited, localised activity found in an inspection |
| Chemical barrier | Install a treated zone in the soil around and under the building, using products such as Termidor | Houses needing long-term perimeter protection |
| Baiting system | Install stations in the ground, such as Sentricon or Exterra, and monitor them over time | Properties where trenching is hard or colonies must be eliminated |
| Barrier top-up | Re-treat gaps or disturbed sections in an existing barrier | Homes with a previous barrier or after landscaping changes |
| Termite prevention advice | Advise on drainage, mulch, ventilation and timber contact with soil, following AS 3660 | New builds, renovations and older homes |
How the white ant treatment job works
- Call and describe what you saw: mention mud tubes, damaged timber or swarms, and avoid disturbing the area.
- Timber pest inspection: a licensed inspector examines accessible areas and reports activity, damage and conducive conditions.
- Written quote: the report is followed by an itemised price that names the method, the products and any warranty.
- Choose the method: spot treatment, a chemical barrier or a baiting system, depending on the findings and your property.
- Treatment day: the licensed technician applies the treatment or installs the stations, and you keep children and pets away as directed.
- Monitoring or follow-up: baits are checked on a schedule and barriers are inspected at the intervals the technician sets.
- Sign-off: you receive a treatment record, a warranty document and a recommended inspection schedule.

For a deeper breakdown, read our termite treatment cost guide.
- Perimeter length: a larger or more complex footprint needs more product and more time.
- Slab, pier or suspended floor: access to the subfloor and the type of footing change the method.
- Site conditions: paving, pools and retaining walls make trenching harder and can push the cost up.
- Extent of activity: a single area of activity is a different job from a colony feeding in several places.
- Product and method: baiting and barriers suit different houses, so compare both quotes.
- Warranty: many pest treatments carry a warranty period with free re-treatment, so compare it as well as the price.
Termite control for homes, strata and commercial
- Freestanding houses: the technician treats the full perimeter and checks sheds, fences and garden timber for links to the house.
- Units and apartments: termites can move through shared walls and common areas, so the owners corporation often coordinates inspections.
- Strata common areas: decks, car parks and landscaped areas are an owners corporation matter, not an individual lot owner’s.
- Rentals: report signs to the agent in writing and keep the landlord informed, because treatment often needs approval.
- Commercial sites: shops and offices need documented inspection schedules, and activity in the building structure should be reported immediately.
- Older timber homes: weatherboard and timber-framed houses benefit from more frequent inspection because the structure itself is food.
What to check before you book termite inspection near me
- Licence: in NSW, anyone using pesticides for fee or reward must hold a pest management technician licence from the NSW EPA; ask to see a copy.
- Inspection standard: ask whether the report follows AS 4349.3 for timber pest inspections.
- Insurance: request proof of public liability cover.
- Written quote: it should name the method, products, areas covered and any exclusions.
- Warranty: check the term, the re-treatment conditions and any inspection duties that keep it valid.
- Management plan: a barrier or baiting job should come with a plan aligned with AS 3660.
- Safety: keep children and pets away, ventilate and store chemicals locked away; never treat a live nest yourself.
FAQs: termite treatment in Sydney
How much does termite treatment cost in Sydney?
Spot treatment typically costs $575, a baiting system $3,000 and a chemical barrier $4,025, with inspections around $345. Price depends on perimeter, access and activity. Get itemised quotes and compare the warranty.
How often should I have a termite inspection?
Most inspectors recommend an inspection every year. Sydney’s mild climate and timber-framed homes make annual checks sensible. Book sooner if you see mud tubes, hollow timber or swarms, and ask for a report that follows AS 4349.3.
What is the difference between termites and white ants?
White ant is the common name for termites, although they are not true ants. See white ants and what white ants look like. The treatment and licensing rules are the same.
Can I treat termites myself?
No. Disturbing a live nest or spraying it can scatter the colony and hide activity. At home you can reduce moisture, keep timber off soil and clear gardens from walls, then book a licensed inspection. Leave all pesticide treatment to a licensed technician.
How do I tell a termite nest from other pests?
Nests are often hidden in trees, stumps or wall voids. Read our guide to a termite nest and the page on the termite queen, then do not touch the area. A licensed inspector can confirm what you have.
How does termite prevention work?
Prevention combines regular inspections, good drainage, ventilation, and a barrier or baiting system around the building. Keep mulch and garden beds clear of walls. A licensed technician advises what suits your house and sets the inspection schedule.
