Is ant treatment a one-off or do I need it regularly?

A single treatment with a 90-day warranty covers most residential ant situations. Properties adjacent to bushland, with heavy garden mulch, or with large established colonies in garden walls or paving benefit from a twice-yearly general pest program that covers ants along with cockroaches, spiders, and silverfish. This is more cost-effective than multiple reactive single treatments for properties with persistent ant pressure.

What is the difference between standard and large infestation pricing?

Standard pricing ($180-$240) applies to properties with a single ant species, perimeter nest sites, and normal property size. Large infestation pricing ($240-$320) applies when multiple ant species are present, multiple nest sites are identified (under paving, in garden walls, along fence lines), or the property has a large treatment area. The technician assesses at inspection whether the job is standard or extended scope.

Is same-day ant treatment available in Brisbane?

Yes. Same-day service is available for most Brisbane suburbs when you call before midday on 0406 178 471. No same-day surcharge applies during standard business hours. Same-day treatment for ants is commonly requested when ants have entered a kitchen or food storage area. Most Brisbane suburbs can be attended the same day when booking by midday.

Why does ant treatment cost more for persistent infestations?

Persistent ant infestations usually involve multiple established nest sites that have been present for one or more seasons. Multiple nest sites under paving, in garden walls, along fence lines, and in mulch beds each require targeted bait placement. Locating and treating all nest sites takes more time than treating a fresh infestation with a single identifiable nest. Properties that have had recurring ant problems without treatment are almost always in the large infestation price category.

Ant Treatment Cost Brisbane 2026

Q: How much does ant treatment cost in Brisbane?

Standard residential ant treatment costs $180-$240 for a 3-4 bedroom house. Large or persistent infestations with multiple nest sites cost $240-$320. Carpenter ant treatment costs $220-$320 due to the specialist timber inspection and drill-and-treat approach required. Commercial premises start from $260 per service. All residential treatments include a 90-day warranty. Same-day service is available without a surcharge during business hours.

Q: Why do carpenter ants cost more to treat?

Carpenter ants nest inside timber and require targeted timber inspection to locate the nest before treatment can begin. In many cases, the nest is accessed by drilling through timber at the nest site and injecting insecticide dust directly into the cavity. This is a different process from perimeter spray and nest bait placement used for garden and pavement ants. The additional inspection time and specialist approach to timber nest treatment is what drives the higher price.

Q: What happens if ants come back within the warranty period?

The 90-day warranty means the same species in the same treated area will be re-treated at no charge. Re-treatment is assessed to confirm the same infestation rather than a new ant trail entering from an untreated area. New nest sites that establish in untreated garden areas after the original treatment are not covered by the warranty for the original treated area, but can be treated at a reduced follow-up rate.

Standard residential $180-$240. Large or persistent infestations $240-$320. Carpenter ants $220-$320. Commercial from $260. 90-day warranty on all treatments. Same-day service without surcharge.

Cost by Ant Species

How Ant Species Affects Treatment Cost

Most Brisbane ant species fall into the standard price range. Carpenter ants are the exception because they require a fundamentally different treatment approach. Fire ants are a separate biosecurity matter entirely.

Black House Ant and Garden Ant

$180-$240 standard range

The most common Brisbane ant species found in kitchens and gardens. Nests in garden beds, under pavers, along fence lines, and in soil at the building perimeter. Standard perimeter spray and targeted nest bait covers most infestations. Responds quickly to treatment. Large persistent colonies nesting in multiple sites move into the $240-$320 range.

Carpenter Ant

$220-$320 specialist treatment

Carpenter ants (Camponotus species) excavate galleries inside timber, including structural building timbers, roof void framing, and fence posts. The nest is inside the timber rather than in soil, which requires a different treatment method: locate the nest by sound (tapping) and moisture meter, drill into the nest cavity, and inject insecticide dust directly. Perimeter spray alone does not reach a carpenter ant nest inside timber. Timber inspection is included in the price.

Fire Ant (Solenopsis invicta)

Biosecurity matter separate process

Fire ants are a biosecurity-regulated pest in Queensland. Suspected fire ant nests must be reported to Biosecurity Queensland on 13 25 23 before any treatment. Treatment under the National Fire Ant Eradication Program is separate from commercial pest control. Do not treat or disturb a suspected fire ant nest independently. See our fire ant page for identification and reporting guidance.

What Affects the Price

Factors That Push Ant Treatment Cost Higher

Most standard Brisbane properties sit at the lower end of the price range. These are the conditions that increase the cost toward the upper end.

Most common factor

Multiple established nest sites

A fresh ant infestation with a single identifiable trail and one nest site is quick to treat. An established infestation that has been present for one or more seasons often has nests under multiple areas: beneath paving, inside garden walls, along fence lines, and in thick mulch beds. Each identified nest site requires targeted bait placement. Finding and treating all sites takes more time than a standard perimeter treatment.

Adds $30-$60

Property size and perimeter

A standard Brisbane suburban block with a 3-4 bedroom house has a perimeter of roughly 50-60 linear metres. Properties on larger blocks with extensive garden coverage, multiple garden zones, or large outbuilding areas require more product and time. The treatment area per square metre drives the price difference between smaller and larger properties.

Specialist surcharge

Timber nest access for carpenter ants

When a carpenter ant nest is inside a building timber, locating it requires working through the property with a moisture meter and stethoscope to find the void. Drilling and injecting into the timber adds time and requires specialist knowledge of building structures. The $220-$320 range reflects the additional inspection and treatment complexity compared to a soil-nesting ant species.

No surcharge

Same-day service

Same-day attendance for ant treatment is available without a same-day surcharge during standard business hours. Call before midday on 0406 178 471.

FAQ

Ant Treatment Cost FAQ

How much does ant treatment cost in Brisbane in 2026?

Standard residential $180-$240. Large or persistent infestation $240-$320. Carpenter ants $220-$320. Commercial from $260. All residential treatments include a 90-day warranty and same-day service without surcharge during business hours. Call 0406 178 471 before midday for same-day attendance.

Why do carpenter ants cost more to treat?

Carpenter ants nest inside timber, not in soil. Treating a carpenter ant nest requires locating it inside the building timber using moisture meter and sound, drilling to access the nest cavity, and injecting insecticide dust directly inside. Perimeter spray does not reach a nest inside structural timber. The timber inspection and drill-and-treat process adds time and specialist knowledge, which is reflected in the $220-$320 price range.

Is ant treatment a one-off or recurring cost?

A single treatment with a 90-day warranty covers most situations. Properties with persistent ant pressure from adjacent bushland, large gardens, or established colonies in paving often benefit from a twice-yearly general pest program covering ants, cockroaches, spiders, and silverfish. This is more cost-effective than three or four individual ant treatments per year.

Why is my ant infestation quoted at the higher end of the range?

The higher end of the range ($240-$320) applies when: multiple nest sites are present across the property, more than one ant species requires treatment, the property is larger than a standard block, or the infestation is established across structural areas requiring extended time. The technician can explain specifically what was found at inspection that places it in the upper range.

What happens if ants come back within the warranty period?

Re-treatment of the same species in the same treated area is performed at no charge within the 90-day warranty period. The return visit confirms whether it is the same infestation rebounding or a new ant trail entering from an area that was not part of the original treatment. New trail entry points discovered at the warranty visit are treated as part of the re-treatment.
