Termite inspections and management in Newcastle and the Hunter

Plate I, the signs

The signs you actually saw

Termites work out of sight, so you almost never see the insect. You see what it leaves behind. These are the things that turn up in the enquiries we read, and what each one usually means.

Mud on a brick pier, slab edge or wall: A mud lead, or mud tube: a covered highway termites build to travel from damp soil to timber without drying out. Pencil-thick, earthy, running vertically up a foundation. It is the single most reliable sign there is, and the reason a subfloor gets checked first.
Timber that sounds hollow when you tap it: Termites eat the soft wood from the inside and leave a paper-thin shell, so a skirting, architrave or door frame that was solid now sounds papery. A blistered or rippled paint surface over timber is the same thing seen from outside.
Doors and windows suddenly tight: Timber that has been hollowed and taken up moisture swells and distorts, so a door that always closed now sticks. On its own it is just a damp house; alongside another sign it is worth a look.
Flying ants at dusk, especially after warm rain: Winged termites, called alates, leaving a mature nest on a colonising flight. They are drawn to light and often turn up at windows on a humid evening in spring or summer. Termite or flying ant is a five-second check: our flying ants or termites guide has it.
A small pile of discarded wings: Alates shed their wings soon after they land and pair off. A scatter of identical narrow wings on a windowsill or in a web means a flight happened nearby, which means a mature nest is within range.
Mud or a dark stain seeping from a skirting or cornice: Workings inside a wall breaking the surface. This is the one that says stop and book, because whatever you can see is a fraction of what is behind it.

If you have found them

Leave it undisturbed. That is the whole rule.

The instinct is to spray it, poke it, pull the skirting off and see how bad it is. Don't. A disturbed colony abandons the workings you found and moves to feed somewhere you cannot see, which turns a located problem into a hidden one and makes the treatment harder. Repellent surface sprays do the same thing.

Cover it back over if you exposed it, keep the kids and the vacuum away from it, and book. Live workings are exactly what a technician needs to see to plan the job, so the best thing you can do is nothing at all until we get there.

Plate II, the local habit

What termites are doing in a Hunter house

Coastal NSW carries termite activity year-round, or close enough to it that season is not much of a defence. The insect itself explains why: subterranean termites are thin-skinned and dry out fast, so they can only reach a building's timber where there is constant moisture and a covered route to travel. The Hunter's housing stock hands them both, from two different directions.

In the old inner ring, the damp comes from underneath. A Federation weatherboard in Mayfield or a terrace off Darby Street sits over a timber subfloor that stays humid in the salt air, and every bearer and joist down there is food with a moisture source attached. Out on the newer estates around Fletcher and Maitland the route is the buried slab edge: a garden bed or a path built up over the edge of the slab lets termites cross from soil to wall frame without ever surfacing, which is exactly the gap an inspection is looking for.

Coptotermes, the genus behind most structural termite damage in Australia, is at home on this coast. That is not a reason to panic about your house; it is the reason a proper inspection is worth more here than a reassuring guess. Only the inspection settles what is actually happening under your floor.

Plate III, the inspection

How a timber pest inspection works

Everything else on this page waits on this. A termite inspection is a methodical look at every place termites reach or hide, worked to AS 4349.3, and it is the honest first step before a single word about treatment. Here is the order it happens in and why.

The subfloor first
In this stock the answer is usually underneath. A technician gets under the house and reads the piers, bearers and joists for mud leads, damaged timber and the moisture that makes the whole thing possible. In a slab home the equivalent is the perimeter, the weep holes and the slab edge where a path or garden has buried it.
The roof void and the interior
Up into the roof space to check the frame and any leaks feeding it, then a room-by-room look at skirtings, architraves, door frames, wet areas and the back of built-in cupboards. Timber gets tapped and sounded; a moisture meter reads the walls that a torch cannot see into.
The grounds and the timber outside
Fences, gates, retaining walls, the deck, stored firewood, tree stumps and the garden beds crowding the house walls. Most termites arrive from the yard, so the conditions out here are half the report.
The findings, in writing
What was found, what could not be reached, the conducive conditions worth fixing, and a clear recommendation. If management is needed the report is what it is built on. If nothing active turns up, you get that in writing too, with a sensible date to look again.

What an inspection cannot do. It is a visual inspection of what can be safely reached. A meter and a thermal camera help find hidden moisture and movement, but nothing can look through a sealed wall or into the ground beneath a slab. That is why it reports the risk conditions honestly and why the sensible pattern is to look again on a set cycle, not once and forget it.

Plate IV, management

If management is needed, two ways to do it

Management follows a confirmed inspection, never a phone guess. Broadly there are two approaches under AS 3660, and the honest answer to which is better is that it depends on your house. Here is what each one actually is, product names left out on purpose.

FIG. 2, the two approachesDiagram, product names left out

Approach A

Chemical soil barrier

Termiticide is worked into the ground at the footings and slab penetrations until the soil the house sits in reads as one treated zone. Modern non-repellent products give no warning of themselves, so foragers walk through and ferry the dose home to the colony instead of steering around it.

Best when: There is active pressure and you want protection working the day it is finished.
The trade-off: It needs full, even soil access, which is harder near waterways, wells or under-slab services, and it is renewed over its service life.

Approach B

Baiting and monitoring

A ring of in-ground stations that termites work, then carry back to the rest of the nest themselves, checked on a cycle. Where a colony is already known, above-ground stations can be fixed directly to the live workings for a faster hit.

Best when: The site is sensitive, or the goal is long-term colony elimination and ongoing watchfulness.
The trade-off: It works over weeks to months rather than at once, and it is an ongoing monitoring relationship, not a one-off.

Which one is a decision, not a default. A good technician recommends the fit for your house from what the inspection found, not from what they would rather sell. The barrier or baiting guide walks the choice through in plain terms, in disruption rather than dollars. Building new or extending? AS 3660.1 has the termite management designed in at the slab stage, so it is worth a conversation before the concrete goes down, not after.

Plate V, conducive conditions

What makes a Hunter house termite-friendly

Age does not decide termite risk. Conditions do. A dry, ventilated, well-kept old house can be a poorer target than a new one with a garden bed piled against the slab. Most of what invites termites is moisture and a hidden path to timber, and a fair bit of it you can fix in a weekend. The conducive conditions guide is the long version; this is the short one.

Worth a weekend

Things a homeowner can usually sort out and take the pressure off.

A leaking tap, gutter or air-conditioner drain keeping the ground damp against the house.
Firewood, timber offcuts or old fence palings stacked against a wall or under the house.
Mulch or a raised garden bed burying the weep holes or the slab edge.
Subfloor vents blocked by soil, plants or stored junk, so the underfloor never dries out.
A path or paving that has buried the slab edge and hidden the one line an inspection reads.

Worth an inspection

Things that need a trained eye, not a guess, to read properly.

A subfloor that stays damp no matter what you do, or a house on low, poorly ventilated ground.
Old stumps or a large tree close to the house with roots and dead wood underground.
An extension, deck or retaining wall where new timber meets old and soil meets frame.
Any bridging you cannot see into: rendered foundations, split-level junctions, sealed cavities.
A house you are about to buy, where the timber pest inspection belongs before you exchange.

Plate VI, worth knowing

The honest fine print

Timber pest work is a licensed job. An ordinary pest licence does not cover it: termite inspection and treatment sit behind a separate timber pest endorsement. That is who does this work, and worth checking before anyone crawls under your house.

We do not sell a warranty on this page. Real timber protection agreements and their terms come from the work actually done and are set out in writing for your house, not promised by a website. Be wary of any big round guarantee number offered before anyone has looked under the floor.

Management is only ever quoted after an inspection. The inspection is a set fee we confirm before booking. What management costs, and whether you need it at all, depends entirely on what the inspection finds. Anyone quoting a treatment sight unseen is guessing, and it is your house they are guessing about.

Buying a place? The pre-purchase timber pest inspection is its own job, timed to your contract and reported to AS 4349.3. It has a page of its own: pre-purchase inspections.

Questions

Asked about termites

I found mud on a pier. Do I have termites?

A mud lead means termites have been building a covered route there, which is the strongest single sign there is. Whether they are active right now, and how far the workings go, is what the inspection settles. Leave it undisturbed and book; do not break it open to look.

Are white ants and termites the same thing?

Yes. White ant is the old common name and it is still what most people search for, but termites are not actually ants at all. Same insect, same job, either way.

My house is brick, so I am safe, right?

No. Brick veneer is a timber frame with a brick skin, and the frame, the roof timbers, the floors and the joinery are all food. Full double-brick still has a timber roof structure and internal fixings. Construction changes where termites get in, not whether they can.

Barrier or baiting, which should I get?

It genuinely depends on the house, the activity and the site, which is why an honest answer waits on the inspection. Broadly, a barrier protects fast once it is in and a baiting system works more slowly toward eliminating the colony. The guide lays out the trade-offs.

How often should an inspection happen?

An inspection is a point in time. The coastal Hunter barely gives termites an off-season, so a regular cycle is the sensible pattern for keeping ahead of it rather than finding out the hard way. The report suggests a date to look again for your particular house.

Can you just spray them for me today?

No, and anyone who offers to is doing you no favours. A surface spray on visible termites scatters the colony to feed out of sight and makes the real job harder. The right order is inspect, understand, then manage. That order is the whole method.
