White Ant Treatment & Inspection Sydney

There's no such thing as a white ant, really. The name stuck because they're pale and they live in colonies like ants, but they're termites. That matters because the two get treated very differently. Ordinary ants you can leave alone or knock back with a bit of surface spray. Termites eat the timber in your house, and they need proper treatment.

A lot of the calls I get about "white ants" or "dust on the floor" turn out to be something else. Ant frass is fine, black, and dusty, like ground pepper. Termite workings are brown mud, solid, not powder. If what you've found is brown mud, get it looked at. If it's fine black dust, it's probably ants. Either way, an inspection tells you for sure.

Whatever you've found, don't spray it and don't poke at it. A surface spray won't reach the colony, and disturbing a nest can make it split and move deeper into the house, which makes the job harder. Leave it alone and get it inspected first.

The inspection comes first

I don't treat anything until I've inspected and know what's there. I go through the whole property: subfloor, roof void, every room, and the outside perimeter. I bring a thermal imaging camera and a moisture meter on every job, because termites work out of sight and the damage is hidden until you go looking with the right gear. See termite inspections for the full scope.

I write the report on-site and hand it to you before I leave, with what I found and what I'd recommend. If there's activity, I'll explain the options on the day.

Treatment options

If the inspection finds termites, the treatment depends on the property and how far the activity's gone. There are three main approaches.

• Chemical barrier. A treated zone in the soil around the house, using Termidor. The termites carry it back to the nest, which takes out the colony. 8-year warranty, conditional on keeping annual inspections up.
• Baiting and monitoring. In-ground stations the termites feed from and carry the bait back to the colony. Lower disruption, no trenching. I use Trelona and Nemesis.
• Pre-construction physical barrier. For new builds only — TermSeal sheeting before the slab pour. 50-year warranty. Can't be retrofitted to an existing home.

I'll tell you which one fits your place and why, and I won't push a treatment you don't need. If it turns out to be nothing, I'll tell you that too. For how the options compare, see termite treatment.

The termites behind the damage

The species behind most structural damage in Sydney is Coptotermes acinaciformis, a subterranean termite. A colony can run to hundreds of thousands of termites, and they can do real damage to the timber in a house before there's anything to see on the surface. That's why annual inspections matter. They catch activity early, before it gets expensive.

Guarantee

White ant treatments carry a 6-month guarantee. The barrier treatments carry their own longer warranties on top — 8 years on a chemical barrier and 50 years on a pre-construction physical barrier — and those stay valid as long as you keep your annual inspections up.

How I work

Every inspection and every treatment is done by me. You call the number and I'm the one who turns up. I've been doing this since 2015, across all sorts of houses. Thermal camera and moisture meter on every visit, the report on-site before I leave, a straight quote, and no upsell.

Common questions

Are white ants and termites the same thing?
Yes. "White ant" is just the common Australian name for a termite. Same insect, same damage, same treatment.

Are white ants dangerous to my house?
They eat timber, so they can do serious structural damage if they're left. The damage happens out of sight, which is why you want them found and dealt with early rather than after it shows.

How do I know if it's white ants or normal ants?
Termite workings are brown mud, solid. Ant frass is fine, black, and dusty. If you're not sure, that's what the inspection is for. Don't disturb whatever you've found before I see it, because knocking into a nest can split the colony.

Can you get rid of white ants for good?
The right treatment takes out the colony, and keeping up annual inspections is how you stay protected and catch anything new before it becomes a problem.

How quickly can white ants damage a house?
It depends on the colony and the timber, but an established colony can do real structural damage over months, not years, and it happens out of sight. That's why catching them early with a yearly inspection makes such a difference.

How soon should I book?
If you've found activity, or you haven't had an inspection in the last 12 months, it's worth booking. Don't disturb the area in the meantime.
