Pest Inspections
Pest Inspections near you
A pest inspection in Australia is nearly always a timber pest inspection, and the timber pest that matters is the termite. The inspector walks the property, the sub-floor and the roof void, reads the moisture and the mud, and writes down what was visible on the day. It is the single most useful few hours you can buy before signing a contract on a house, and it is also the most widely misunderstood.

The misunderstanding is about reach. A standard inspection is visual and non-invasive: nobody cuts open a wall, lifts a floor covering or moves the owner's stored boxes in the garage. Anywhere the inspector could not see becomes a limitation recorded in the report, and those limitations are the part worth reading first, because they describe where a problem could still be sitting.
Start with the durable notice in the meter box, which under clause 3.4.3 of the NCC 2022 Housing Provisions records the termite management system, its installation date, any chemical life expectancy and the recommended scope and frequency of future inspections. If it is missing, faded or decades old, that is information about the building before the inspector has opened a torch. In New South Wales, the person carrying out a commercial termite treatment must hold an EPA pest management technician licence, so ask to see the licence as well as the quote.
The inspections Australian homeowners actually book
- A pre-purchase timber pest inspection, usually taken together with a separate building inspection and made a condition of the contract.
- A routine periodic inspection on the cycle the durable notice recommends, which is what keeps a management system meaningful.
- An inspection triggered by something found — a mud lead, a hollow architrave or a swarm of winged insects at dusk.
- A pre-treatment inspection that maps the building before a barrier or baiting system is designed for it.
- A post-treatment or reinstatement inspection confirming a system has gone back in after renovation work cut through it.
- A handover inspection on a new build, where the point is to confirm the system that was specified is the system that was installed.
What a thorough inspection covers on the day
- The full external perimeter at ground level, looking at the slab edge, weep holes, paving levels and garden beds against walls.
- The sub-floor where there is one, which is where piers, bearers and ventilation either tell a story or hide one.
- The roof void, including the ends of rafters and the top plates, reached properly rather than from the manhole.
- Wet areas and their surrounds, because a shower that has been leaking quietly is the classic termite invitation.
- The garden within the boundary: stumps, retaining walls, sleepers, landscape timbers and stacked firewood.
- Moisture readings and sounding of accessible timber, which is how an inspector finds what the eye cannot see.
- Photographs of anything reported, so a later argument about what was visible on the day has evidence behind it.
Licensing, and the difference between a building report and a pest report
These are two different reports written by two differently qualified people, even when one company sells them as a package. The building report is about structure, weatherproofing and defects. The timber pest report is about termites, borers and decay, and about the conditions that make them likely. Neither one substitutes for the other, and a combined booking should still produce two documents.
Licensing is a state matter. In New South Wales, a pest management technician licence is issued by the EPA, is valid for five years, requires the applicant to be at least eighteen and to have completed three specified training modules from an accredited provider, and covers conducting commercial termite treatments. Other states and territories run their own licensing schemes through their own regulators, so check the requirement where the property is rather than assuming the New South Wales arrangement applies nationally.
Why a clear report is not the same as a clear house
- Stored goods in a garage or under the house hide exactly the surfaces an inspector most wants to see.
- A sub-floor with no crawl height cannot be entered, so a whole elevation may be reported as inaccessible.
- Rendered or clad slab edges remove the one place a mud lead would have been obvious from outside.
- Fixed floor coverings, built-in robes and kitchen kickboards all conceal the timber underneath them.
- A recently painted and patched interior can be tidy work or can be a repair nobody wants discussed.
- An inspection is a snapshot: a property can be clear in March and have live activity by December.
What the report promises, and what to keep
Read the scope and limitations before the findings. They define what the inspector was engaged to look at, what was accessible, and what was expressly excluded, and they are the terms you are actually buying. If the limitations swallow half the building, the sensible response is to arrange access and have the inspector come back rather than to accept the report as it stands.
Keep every report, every invoice and a photograph of the durable notice in one file with the building's other records. Over a decade that file becomes the evidence that the property has been managed, which matters when you sell and matters again if there is ever a dispute about when something started.
What you can check yourself between inspections
- Walk the perimeter after heavy rain and look for soil, mulch or paving that has crept up over the slab edge.
- Tap skirtings and door jambs in bathrooms, laundries and any room on an external wall, and listen for a papery sound.
- Look for wings on window sills and in webs after warm humid nights, which is the cheapest early warning there is.
- Keep firewood, timber offcuts and garden sleepers off the ground and away from walls.
- Check that sub-floor vents are not blocked by a new garden bed, a rainwater tank or a stack of pavers.
- Photograph anything odd with something in frame for scale, so the inspector can see what it looked like before you touched it.
Pest Inspections: frequently asked questions
How often should an Australian house have a termite inspection?
The honest answer is written on the building rather than in a general rule. Clause 3.4.3 of the NCC 2022 Housing Provisions requires the durable notice to state the installer's or manufacturer's recommendations for the scope and frequency of future inspections, and that recommendation is specific to the system installed and to the site. Where there is no notice — which is common in older houses — the interval becomes a judgement made with the inspector, based on construction type, how much of the perimeter can be seen, and whether there is a history of activity nearby.
Is a building inspection the same as a pest inspection?
No, and buying one while believing you have bought the other is the most expensive mistake in this whole area. A building inspection reports on structure, defects and weatherproofing. A timber pest inspection reports on termites, wood-boring insects and decay, and on the conditions that invite them. They are often sold together and carried out on the same visit, but they are separate engagements producing separate documents. Ask for both reports in writing, and read the limitations in each.
Will the inspector open up walls or lift the carpet?
Not on a standard inspection. The usual engagement is visual and non-invasive, which means the inspector looks, sounds timber, takes moisture readings and photographs, but does not cut, drill or lift finishes. If something is suspected behind a finish, that becomes a recommendation for further invasive investigation, which is a separate job usually needing the owner's written permission. This is why the limitations section matters: it tells you which parts of the building the report simply does not speak for.
Does the person doing the inspection need a licence?
Yes, and the licence is issued by the state. In New South Wales the EPA issues a pest management technician licence, valid for five years, to applicants aged at least eighteen who have completed three specified training modules with an accredited provider, and it covers conducting commercial termite treatments. Every state and territory runs an equivalent scheme through its own regulator with its own name and conditions, so ask to see the licence card and check it against the register for the state you are in.
The house is being auctioned. Is an inspection still worth it?
It is worth more, not less, because at auction there is no cooling-off period and no condition to fall back on. Booking a timber pest inspection before the day costs you a fee on a property you may not win, which is genuinely annoying, but it is the only point at which the information can still change your decision. If you cannot arrange access before the auction, at least look for the durable notice in the meter box on inspection day and photograph it.

What affects the cost of pest inspection
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 pest control technicians 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 pest control technicians 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 inspection
- 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 inspection permits and local rules
Some pest inspection 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.
