Pest Control
Pest Control near you
Pest control in Australia is dominated by one insect. The Victorian Building Authority states that termites cause more damage to Australian houses than fire, floods and storms combined, and that the damage may not be covered by household insurance. Subterranean termites work out of sight, inside wall frames and under floors, and a colony can be established in a house for a long time before anything shows on the surface. Everything else a pest technician deals with — cockroaches, ants, spiders, rodents, fleas, bed bugs, wasps — is a nuisance by comparison.

Because termites are structural, Australia manages them through the building rules as well as through pest treatment. The National Construction Code requires a termite management system where a house is built in an area with a risk of subterranean termite attack, and AS 3660.1 is the referenced standard for new building work, with AS 3660.2 covering detection and management in and around existing buildings.
Pest technicians are licensed by state, not nationally, and the licence that lets someone apply pesticides is separate from any building licence they may also need. Australia has around 350 termite species, of which roughly thirty are pests. Homeowners still commonly call them white ants, which is a misnomer — they are not ants — but it is the phrase most technicians will hear from a caller.
Termites and the other pests Australian homes call about
A good technician identifies the pest before proposing a treatment, because the approach for a timber pest is nothing like the approach for a general pest. The work divides roughly as follows.
- Subterranean termites, still widely called white ants: the structural threat, usually nesting outside the building and entering through ground contact, and the reason timber pest inspections exist as a separate discipline.
- Other timber pests: borers and decay fungi, which are assessed in the same inspection as termites but managed differently.
- Cockroaches: a year-round problem in warm and humid parts of the country, treated with baiting and targeted application rather than general spraying.
- Ants: genuinely ants, unlike white ants, and mostly a nuisance except where they nest in wall cavities or under paving.
- Rodents: rats and mice, where sealing entry points and removing food sources matters as much as baiting.
- Spiders: a routine call in most of Australia, with treatment focused on webs, eaves and the perimeter.
- Bed bugs, fleas and wasps: episodic problems that need preparation by the household and often more than one visit.
Signs of termite activity a homeowner can actually spot
Termite activity usually occurs in concealed areas, which is why it is hard to detect and why regular looking around your own home is worth the effort. What you are looking for is not usually an insect — it is the evidence it leaves behind.
- A dull, hollow sound when you tap timber such as skirting boards, door jambs or architraves.
- Blistered or bubbled paint, or wall linings that bulge slightly where they should be flat.
- Small mud tunnels running up external walls, footings, brickwork or paths towards the house.
- Timber that is weak and breaks easily, revealing wafer-thin layers inside.
- Changes in the corner fascia under the gutters, where damage often shows before anywhere else outside.
- If you find any of it, do not disturb the nests, mud tunnels, paths or trails — leave them intact so a technician can work out where the activity is coming from, and book an inspection.
Pest technician licensing is a state matter, and termite work has extra layers
There is no single national pest control licence in Australia. In New South Wales, the Environment Protection Authority licenses pest management technicians, who must hold a licence to apply pesticides to control pests for fee or reward, with trainees holding a training permit. A separate timber pest management technician licence is being phased in; in the meantime a pest management technician licence permits commercial termite treatments. Notably, someone who only carries out timber pest inspections without using pesticides, or who installs termite barriers that contain no pesticide, does not need an EPA licence for that work — so 'licensed' means different things depending on what you are asking the business to do.
Queensland splits it across two regulators. Pest management activities using a pesticide or fumigant are regulated under the Medicines and Poisons Act 2019 and its pest management regulation, and require a pest management licence issued by Queensland Health. On top of that, chemical termite management work — pre-slab and perimeter chemical treatment of new building work, and inspecting or investigating buildings and advising on termite management systems and infestations — falls under a QBCC termite management (chemical) licence, and the QBCC states that anyone supervising or performing that work must also hold the Queensland Health pest management licence.
Other states and territories have their own equivalents. The practical step for a homeowner is to ask which licences the technician holds, in which state, and for what activities, then check them on the issuing regulator's register rather than accepting a logo on a van.
Pre-purchase timber pest inspections when buying a house
A timber pest inspection before buying is close to standard practice in Australian property transactions, and it is not the same thing as a building inspection. NSW Fair Trading makes the distinction plainly: a building inspection report covers the property's condition and significant defects, and while it should identify visible damage caused by termites, it will not tell you whether termites and other timber-destroying pests are still present. A separate pest inspection is needed, and it matters most where termites are known to be a problem — which is most of the country.
The relevant standard is AS 4349.3, Inspection of buildings, Part 3: Timber pest inspections, which sets the criteria for these reports. Ask which standard the inspector is reporting to, and read the limitations section of the report carefully: an inspection of this kind is visual and non-invasive, so it reports on what was accessible on the day and will list the areas that could not be inspected, such as a sealed subfloor or a full roof cavity.
The Victorian Building Authority strongly recommends having an expert inspect a house for termite activity before you buy, and engaging a properly qualified, experienced and insured pest inspector to report on it. NSW Fair Trading similarly advises making sure your consultant has adequate insurance cover, particularly professional indemnity, since that is what stands behind the report if something significant is missed. If you are bidding at auction, the inspection has to happen before the hammer falls, because there is no cooling-off period to fall back on.
Annual inspections and keeping a termite management system working
A termite management system is not a permanent solution that can be installed and forgotten. The QBCC advises homeowners to hire a licensed pest controller to inspect and report on the property every year, or more often in high hazard areas, and to keep up the system's own maintenance requirements, such as the yearly top-ups a chemical barrier may need. Those requirements are recorded on the termite management notice — a durable notice the National Construction Code requires to be permanently fixed in a prominent location, typically the meter box, stating the system used, the date of installation, the life expectancy of any chemicals used and the installer's recommendations for the scope and frequency of inspections. Find yours before you book anything; it tells the technician what they are dealing with.
It also helps to understand what these systems actually do. They protect the primary structural elements and are designed to make termite entry detectable during inspection rather than to guarantee that termites can never reach the building. That is why the inspection routine, not the barrier, is the part that catches an infestation early. Renovations are the usual way a working system gets compromised: adding garden beds, a patio or new landscaping can create a concealed path around the barrier.
- Keep garden beds, shrubs, trees and bark or mulch away from the walls of the house, since built-up material lets termites reach the building undetected.
- Keep the weep holes between the bricks and the concrete slab open and clear, rather than covering them with soil, paving or render.
- Fix leaking taps, plumbing leaks, drainage problems and roof leaks promptly, because termites are drawn to damp conditions.
- Keep loose timber, offcuts and firewood off the ground and away from the house.
- Tell your pest technician about any landscaping, paving or extension work done since the last inspection.
- Keep the inspection reports — a sequence of them is far more useful than any single report on its own.
Why termite damage is worse than it looks, and what insurance may not cover
Two things make termites unusually expensive in Australia. The first is concealment: because activity happens inside wall cavities, under floors and within frames, the damage is structural by the time it is visible, and the repair is carpentry rather than pest treatment. The second is insurance. The Victorian Building Authority warns that termite damage may not be covered by household insurance, which leaves the repair bill with the owner even though the loss can be larger than many insured events.
There is also a safety dimension that is easy to overlook. Weakening structural timber does not only cost money — the chair of the Standards Australia technical committee behind the termite management standards has pointed out that termites pose an often overlooked threat to health and safety, and that the weakening of structures increases the likelihood of serious damage in a storm, flood or fire. A house with quietly compromised framing is less able to withstand the other hazards Australia regularly delivers.
Termite management options: barriers, chemical treatment and resistant construction
For new building work, AS 3660.1 is the standard behind the National Construction Code's termite risk management requirements, and it sets out the approaches available — including using timber that is naturally termite-resistant or timber that has been preservative-treated. For a house that already exists, AS 3660.2 covers detection and management of subterranean termite activity in and around existing buildings and structures, including determining the extent of an infestation, the treatment to control or eradicate it, and managing the risk of reinfestation.
The Victorian Building Authority notes that for a new home or an extension, an owner can choose termite-resistant primary structures — concrete slabs, termite-resistant timber, steel frames — which do not depend on a regular maintenance system in the way a chemical barrier does. That is a design decision worth making early, because it is far cheaper than retrofitting.
When AS 3660.2 was revised, the intent was to move the conversation past which chemical to use. As the committee chair put it, consumers can now make decisions based on inspection data and management proposals to decide on the best way to manage termites. That is the right way to read a technician's quote: the inspection findings and the proposed management plan should justify the treatment, not the other way around.
Written treatment plans, your consumer rights and using LokalMatch
Australian Consumer Law gives you guarantees that cannot be excluded: a service must be supplied with due care and skill, must be fit for any purpose you made known, and must be supplied within a reasonable time where none was agreed. For pest work, insist the plan is in writing — the pest identified, the evidence for it, the products or systems proposed, the areas covered, what could not be inspected, the follow-up visits included and what happens if activity is found again.
Finding technicians is what LokalMatch does. Describe the problem once — the pest if you know it, the signs you have seen, the age and type of the building, your postcode — and pest control businesses working in your area contact you themselves. Those businesses pay LokalMatch for the requests they take on, which is how the service is funded, and it costs a homeowner nothing to describe a job. LokalMatch does not carry out inspections or treatments, does not quote or set prices, and does not vet, rank or recommend any business, so confirming a technician's state licence remains something you do yourself.
Pest Control: frequently asked questions
Are white ants the same thing as termites?
Yes, in everyday Australian usage — white ants is the colloquial name for subterranean termites. Biologically it is a misnomer, because termites are not ants at all, but it is what most people call them when they ring a pest controller. Australia has around 350 termite species, of which roughly thirty are considered pests.
How often should I have my house inspected for termites?
The QBCC advises engaging a licensed pest controller to inspect and report on your property every year, or more often in high hazard areas. Your own termite management notice may specify a different scope and frequency, since the National Construction Code requires that notice to record the installer's or manufacturer's inspection recommendations. Regular checks of your own around the house between professional inspections are worth doing as well.
Will my home insurance cover termite damage?
Often not. The Victorian Building Authority warns that termite damage may not be covered by household insurance, despite termites causing more damage to Australian houses than fire, floods and storms combined. Read your own policy and its exclusions rather than assuming, and treat the inspection routine as your real protection.
Do I need a separate pest inspection when buying, or is the building report enough?
You need both. NSW Fair Trading points out that while a building inspection report should identify visible damage caused by termites, it will not tell you whether termites and other timber-destroying pests are still present, so a separate pest inspection is advised, especially where termites are a known problem. Timber pest inspections are reported to AS 4349.3, and it is worth checking that your inspector carries professional indemnity insurance.
Is my pest technician licensed?
That depends on the state and the work. In New South Wales, the EPA licenses pest management technicians who apply pesticides for fee or reward, with a timber pest management technician licence being phased in; inspection-only work using no pesticides does not require that licence. In Queensland, applying pesticides requires a Queensland Health pest management licence, and chemical termite management work also requires a QBCC licence. Ask which licences they hold and verify them with the issuing regulator.
I have found mud tunnels on my wall. What should I do first?
Leave them alone. Do not disturb nests, mud tunnels, paths or trails — breaking them up can push the colony to relocate within the building and makes it harder for a technician to trace where the activity is entering. Take a photo, note where you found it, and book a full inspection with a licensed pest controller promptly.
Does a termite barrier mean my house is safe?
Not on its own. Termite management systems are designed to protect the primary structural elements and to make entry detectable during inspection, rather than to guarantee termites can never reach the building. They also need their own upkeep, such as the yearly chemical top-ups a barrier may require, and renovations like new garden beds, patios or landscaping can compromise a system that was previously working.

What affects the cost of pest control
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Type of pest or animal
- How widespread the problem is
- Size of the home and number of units affected
- Treatment method
- Number of follow-up visits
- Exclusion work, such as sealing gaps or installing barriers
How to compare exterminators before you hire
- Choose a company that inspects first and identifies the pest before recommending treatment.
- Ask whether they are licensed to apply pest control products in your area.
- For wildlife like raccoons, squirrels or birds, look for a company that uses humane removal and seals entry points.
- Ask how they'll keep children, pets and food safe during and after treatment.
- Get the treatment plan in writing, including follow-up visits and what happens if the problem comes back.
Questions to ask exterminators before you hire
- What pest do you think this is, and how did you identify it?
- Are you licensed to apply pest control products in my area?
- What products or methods will you use, and are they safe around children and pets?
- How do I need to prepare my home before treatment?
- How many visits are included, and what happens if the problem comes back?
- Will you seal entry points so the problem doesn't return?
When to call a pro for pest control
- Droppings, gnaw marks or scratching noises in walls or the attic
- Bites or small blood spots on bedding that could point to bed bugs
- A wasp or hornet nest near a door, deck or play area
- An animal living in the attic, chimney or under a deck
Pest control permits and local rules
Some pest control work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
