Pest Fox treats sugar ants, black house ants, coastal brown ants and Argentine ants in homes and businesses across metro Adelaide and the Hills. We use gel baits and non-repellent perimeter treatments that reach the colony, not just the trail. A typical residential ant treatment costs $180–$350. Send the quote form or call for a written quote.
Ant control in Adelaide isn’t a can of surface spray. The trail you can see is a small fraction of the colony — kill the foragers and the queen sends out replacements. Pest Fox uses targeted gel baiting and non-repellent perimeter treatments that the workers carry back to the colony, taking out the queen and the brood. Same-day service across metro Adelaide where we can, $180–$350 for a typical residential treatment.

The Adelaide ant species you’ll actually see
Adelaide has a stable cast of ant species turning up on residential jobs. The species drives the treatment — what works on a sugar ant trail won’t dent an Argentine ant super-colony.
- Black house ant (Ochetellus glaber) — small, shiny black, 2–3mm, the most common indoor ant in Adelaide kitchens. Trails to anything sweet or greasy. Nests in wall voids, slab cracks, weep holes.
- Sugar ant / banded sugar ant (Camponotus consobrinus) — larger (up to 12mm), orange-and-black banded, mostly nocturnal, conspicuous trails along skirtings and benchtops at night. Garden-based colonies, foraging indoors.
- Coastal brown ant (Pheidole megacephala) — small (1.5–3mm), light brown, with two distinct caste sizes (the larger “soldier” caste has an oversized head). Common in coastal western suburbs and across the metro. Can form very large, spread-out colonies.
- Argentine ant (Linepithema humile) — small (2–3mm), light brown, smooth-bodied, an introduced species. Doesn’t fight other Argentine colonies — instead they merge, forming continuous super-colonies. Trail discipline is high; they’re the species you see in single-file lines on benchtops.
- White-footed house ant (Technomyrmex difficilis) — small (2–3mm), black with pale lower legs. Indoors year-round, particularly in eastern-suburb kitchens.
- Bull ants (Myrmecia spp.) — large (8–25mm), aggressive, ground-nesting. Garden problem more than indoor; painful sting; foothills and Adelaide Hills properties most affected.
- Carpenter ants (Camponotus spp.) — large, hollow out wood for nesting (don’t eat it like termites do). Less common indoors, but turn up in damaged timbers and tree stumps near the house.
- Pavement ant and Pharaoh ant — turn up occasionally; species-confirmed during the inspection.
Ant control and ant removal in Adelaide: which treatment for which ant
| Ant | Where you’ll see it | What usually works |
|---|---|---|
| Black house ant | Kitchen benches, bathrooms, along skirtings | Gel bait at trails and nest entries, plus a non-repellent perimeter treatment |
| Sugar ant | Night-time trails indoors, nests in the garden | Bait placed on the trail, treatment of garden nests and entry points |
| Coastal brown ant | Paving, garden edges, along slab edges, coastal suburbs | Broad perimeter treatment plus granular or gel bait across the colony area |
| Argentine ant | Single-file lines on benches and outdoor paths | Bait programs over a wider area, often with a follow-up visit |
| Bull ant | Lawn and garden mounds, foothills and Hills properties | Direct nest treatment; see our bull ant guide |

Why surface spray makes ants worse
The mistake every DIY ant treatment makes: kill the visible foragers with a repellent surface spray and the colony detects the threat, sends out replacement workers on a different route, and splits (“budding”) into multiple sub-colonies. You started with one trail and you end with three.
Effective treatment uses non-repellent products the foragers don’t detect, plus slow-acting gel baits the foragers actually carry back to the queen. The workers self-deliver the active to the colony centre. That’s how the queen and the brood are eliminated.
Our process
A typical ant treatment runs to an assess–treat–follow-up pattern, completed in a single morning visit:
- Assess — identify the species (different ants take different baits), trace trails to harbourage points, identify nest entry points (slab cracks, weep holes, eaves, garden-bed edges), and confirm what we’re treating around (food storage, pet bowls, fish tanks).
- Treat — gel baits placed at trail interception points, internal harbourages, and external nest sites. Non-repellent perimeter spray to slab edge, weep holes, eaves, and identified entry points. Where wall-cavity nests are confirmed, dust application via existing access points (power outlets, light switches, vent screens).
- Follow-up — written treatment record, re-entry timing brief, and what to expect over the following weeks as the bait works. Stubborn species (Argentine, coastal brown super-colonies) sometimes need a second visit; your written quote will say whether one is included.
A standard residential ant treatment takes 60–90 minutes. Surface treatments dry in 1–2 hours.
Ant treatment cost in Adelaide
A standard residential ant treatment in Adelaide runs $180–$350. The variables:
- Property size — perimeter length and number of internal trails to address
- Species — Argentine and coastal brown super-colonies need broader perimeter coverage and more bait volume than a single black house ant trail
- Severity — established multi-trail infestations vs precautionary single-trail treatment
- Combined treatment — many ant jobs are bundled with a general pest treatment at the same visit, which comes in cheaper than two separate jobs
We quote in writing. Same-day phone quotes available on standard residential jobs.
When to book
- A persistent kitchen trail you can’t break
- Sugar ants taking over the pantry
- Bull ants nesting in the lawn near where the kids play
- Argentine or coastal brown super-colonies running across the patio
- Ants emerging from wall outlets, light switches, or skirting gaps (wall-cavity nest)
- Spring (warmer ground triggers foraging activity) or after heavy summer rain
If the trail’s been there more than a week, the colony’s established. Don’t wait it out.
Safe around kids and pets
We use APVMA-registered products applied to the label. Surface treatments are touch-safe once dry (1–2 hours). Gel baits are placed in cracks, behind appliances, and inside bait stations — not on accessible surfaces. Tell us at booking if you’d prefer chemical-light gel-only options for sensitive households.
Where we work
We treat ant jobs across Greater Adelaide and the Adelaide Hills. Common patterns by area: coastal western suburbs (coastal brown super-colonies — Henley Beach, Glenelg, Semaphore), inner east heritage homes (sugar ants and white-footed house ants — Norwood, Unley, Walkerville), foothills properties (bull ants — Mitcham, Belair, Stirling), and post-war stock with reactive clay soils (slab-crack entry — Salisbury, Marion, Tea Tree Gully).

FAQs about ant control in Adelaide
Q: How much does ant control cost in Adelaide? A: A standard residential ant treatment runs $180–$350. Property size, ant species, severity, and whether you bundle with a general pest treatment all move the price.
Q: What’s the difference between ants and termites? A: Ants have a clearly pinched waist; termites have a thick, straight body with no waist. Ants have bent (elbowed) antennae; termites have straight, beaded antennae. Worker ants are usually dark; worker termites are pale cream-white. Winged ants have unequal-length wings; winged termites have four equal-length wings. If you’ve got winged insects in late spring and you’re not sure, photograph one and send it through — we’ll tell you. (And if it’s termites, that’s a different page — see termite inspections.)
Q: Will the ants come back? A: A correctly executed gel-bait + non-repellent perimeter treatment targets the colony causing the problem. New colonies can move in from outside the property over time, particularly with coastal brown and Argentine ants, which can form very large, spread-out colonies. A recurring quarterly or 6-monthly program keeps the perimeter active and prevents re-establishment.
Q: Is the treatment safe around kids and pets? A: Yes. APVMA-registered products applied to the label. Surface treatments dry in 1–2 hours and are touch-safe once dry. Gel baits are placed in inaccessible locations. Chemical-light options available — ask at booking.
Q: I’ve already used surface spray and it made it worse — why? A: Repellent surface sprays scatter the colony. The foragers detect the chemical, communicate the threat, and the colony “buds” — splits into sub-colonies in fresh locations. You go from one visible trail to three. Non-repellent products don’t trigger this defensive split, which is why the trade has moved away from spray-only treatments for ants.
Q: What ants are most common in Adelaide? A: Black house ant indoors year-round; sugar ants nocturnally on benchtops; coastal brown ant in coastal western suburbs and increasingly metro-wide; Argentine ant in pockets across the metro; white-footed house ant in eastern suburbs; bull ants on foothills properties.
Q: I keep seeing flying ants — should I worry? A: Flying ants are reproductive winged adults (alates) leaving an established colony to start new ones. They’re a sign the colony’s mature and it’s the right time to book a treatment. Worth checking they’re not winged termites — see the body/antenna/wing test above, or send a photo.
Q: Do you do white ant control? A: “White ants” are termites, not ants, and they need a different approach: an inspection first, then a termite treatment if activity is found. See termite inspections and termite treatments in Adelaide.
Q: How long does ant removal take to work? A: Baits work through the colony, so you’ll usually see more ants at the bait for a few days, then a clear drop. Don’t spray the trail while the bait is working, or you’ll stop the workers carrying it back to the nest.
