A pencil-thin mud tube climbing a brick pier, a skirting board that suddenly sounds hollow, or a door that starts sticking for no obvious reason can be the first visible sign of a much bigger termite problem. The best termite inspection checklist helps you look in the right places before damage becomes expensive, but it is not a substitute for a thorough professional inspection.

Termites can work behind walls, below floors and inside roof timbers for years with little surface evidence. In Victorian homes, especially older properties with subfloors, extensions or timber close to soil, the goal is not to guess whether termites are present. It is to identify risk, preserve evidence and act before they reach structural timber.

Best Termite Inspection Checklist: Start Outside

Most termite activity begins outside the home. Walk the full perimeter slowly, including side passages, decks, garden beds, garages and any area where timber meets the ground. Take photos of anything unusual, but do not pull apart suspected termite workings. Disturbing an active colony can cause termites to retreat and reappear elsewhere.

Check these high-risk areas carefully:

• Brickwork, concrete stumps and slab edges: Look for narrow mud tubes or packed-earth trails. Subterranean termites use these covered pathways to travel between soil and timber while staying protected from air and light.
• Timber close to the ground: Inspect fence posts, sleepers, garden edging, timber retaining walls, decking supports, pergolas and stored timber. Decaying or damp timber in contact with soil is an easy entry point.
• Garden beds and mulch: Soil or mulch built above weep holes can create a hidden bridge into the building. Weep holes should remain visible and clear, not covered by mulch, paving, soil or stored items.
• Moisture sources: Check leaking taps, downpipes discharging near the house, poor drainage, air-conditioning overflow and damp areas beneath decks. Termites are attracted to conditions that provide reliable moisture.
• External timber and trim: Probe only gently where timber is visibly weathered or damaged. Blistered paint, soft patches, unexplained cracks or timber that sounds papery can warrant closer investigation.

A common mistake is assuming a concrete slab makes a home termite-proof. It does not. Termites can enter through tiny cracks, service penetrations, expansion joints and concealed paths behind cladding or render.

Inspect the Interior Without Causing Damage

Inside, focus on changes that do not have a clear explanation. Termite damage is often concealed beneath paint, plaster or flooring, so visible damage may be limited until the activity is well established.

Start with skirting boards, architraves, door frames, window frames and built-in cabinetry, particularly around bathrooms, laundries and kitchens. These rooms are worth attention because plumbing leaks and humidity can create favourable conditions. Look for rippling paint, bubbling surfaces, fine cracks, sagging timber or tiny pinholes in plaster.

Open and close doors and windows. Sticking does not automatically mean termites – seasonal movement, humidity and settlement are common causes – but a recently warped frame alongside other warning signs should not be ignored. Check floors for a soft, springy or hollow feel, especially near external walls and wet areas.

If you find discarded wings near windows, doors or lights, collect a sample or photograph it. Flying termites, known as alates, swarm when a colony is mature and conditions are right. However, winged ants can look similar. A pest professional can identify the insect and advise whether it signals a nearby termite colony.

Avoid drilling, cutting open walls or spraying suspected activity with supermarket insecticide. A quick spray may kill the termites you see while leaving the colony untouched. Worse, it can make a professional assessment more difficult and drive activity into less visible areas.

Check the Subfloor, If It Is Safe to Access

A raised home with a subfloor needs particular attention. Only enter if access is safe, dry and clear, and never crawl into a confined area with damaged wiring, standing water, poor ventilation or unstable flooring overhead.

Use a torch to inspect stumps, bearers, joists, floorboards and timber around plumbing penetrations. Look for mud leads travelling up stumps or walls, earth packed into timber joints, damaged timber and excess moisture. Also check whether ventilation vents are blocked by soil, vegetation or stored goods. Poor ventilation increases moisture and makes the subfloor more attractive to termites.

Subfloor inspections are where a DIY check has clear limits. Restricted access, insulation, ducting and stored materials can conceal large sections of timber. A professional termite inspection uses specialist tools and a systematic process to assess accessible areas properly, then identifies any limitations in the report.

Do Not Forget the Roof Void

Termites do not only attack floors. They can reach roof timbers through wall cavities, plumbing routes and concealed construction gaps. If a roof void is safely accessible, look from the entry point with a torch for mud material on timbers, damaged trusses, unexplained timber debris or moisture around roof leaks.

Do not walk across ceiling plasterboard or place weight on insulation. If the area is difficult to access, leave it to an inspector. The point of a checklist is to reduce risk, not create another repair bill.

Check the Conditions That Make Termites More Likely

Termite inspections should assess more than active insects. A good inspection also identifies the conditions that make an infestation more likely in the future.

Pay attention to timber-to-soil contact, water pooling against the building, leaking plumbing, inadequate subfloor ventilation, dense vegetation touching walls and stored cardboard or timber under the home. Firewood stacked beside the house is another regular issue. Keep it raised from the ground and positioned well away from the building.

If the property has an existing termite management system, do not assume it remains effective forever. Physical barriers can be bridged or damaged during landscaping and renovations. Chemical systems require the correct installation, documentation and ongoing checks. Ask for records showing what system was installed, when it was installed and when it was last inspected or replenished.

Renovations also change termite risk. New decks, garden beds, paved paths, plumbing work and extensions can conceal access points or interfere with existing protection. If work has recently been completed, include those areas in the inspection.

When a Professional Termite Inspection Is Non-Negotiable

Book a professional inspection immediately if you find mud tubes, soft or hollow timber, unexplained moisture damage, winged insects indoors or visible termite activity. The same applies if a neighbour has confirmed termites nearby. Colonies forage widely, and waiting for more obvious evidence is rarely a smart saving.

A professional inspection is also essential before buying a property. A standard building inspection may flag general concerns, but it is not automatically a detailed timber pest inspection. Confirm exactly what has been inspected, which areas were inaccessible and whether the report addresses termite risk as well as visible damage.

For established Victorian homes, annual inspections are a sensible baseline. Higher-risk properties may need more frequent reviews, particularly where there is a history of termites, substantial timber landscaping, damp subfloors, poor drainage or nearby construction. The right interval depends on the property, its protection system and the risks found during the inspection.

What a Proper Inspection Report Should Give You

A proper termite inspection should leave you with more than a verbal reassurance. You need a clear record of accessible areas checked, any areas that could not be inspected, evidence of active or previous termite activity, contributing conditions and practical next steps. Photographs matter because they show you exactly what was found and where.

If termites are active, ask how the proposed treatment targets the colony, how long monitoring will continue and what prevention work is recommended after treatment. The cheapest quote can be costly if it deals only with visible insects and ignores the moisture, entry points or damaged barriers that allowed the issue to develop.

At Zeropest Australia, the focus is on clear findings, evidence you can see and a plan that addresses both active termites and the conditions that help them return.

A careful check around your home can reveal the warning signs early. If something does not look right, photograph it, leave it undisturbed and arrange an inspection before termites have more time to work out of sight.
