Budding splits the colony
Argentine ants and a number of house ants carry multiple queens. Spray them with a repellent and a queen plus a few hundred workers simply moves out and starts again nearby.

Where Birrong sits, who covers it and what it costs.
Birrong sits about 17.4 km west of the CBD in the Canterbury-Bankstown, and postcode 2143 is one we are in most weeks. We run Birrong on a regular route, and same-day attendance is usually available.
If you are near Rose Park, Maluga Passive Park or Little Saigon Plaza, that is ground we cover constantly - it is the busiest part of Birrong for us.
Canterbury-Bankstown is the council area for Birrong, and we treat Potts Hill, Regents Park and Yagoona on the same schedule. Terraces, semis and converted blocks share cavities and risers, which is why a single-unit treatment often does not hold on its own.
Most Birrong bookings come in as apartments and converted blocks where the kitchen backs onto a service riser. Say which one applies when you call 1300 313 373 and the technician will have the right products on the van.
Our Birrong runs also take in Bass Hill Plaza and the area near Birrong station, so the whole postcode is served.
Bookings for 2143 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Potts Hill and Regents Park often share the same run, which is how earlier slots come up.
Many ants get most of their sugar from honeydew - the secretion of aphids and scale insects they actively protect on garden plants. A Birrong garden with a scale problem is feeding the ant colony that then comes indoors.
People expect a single nest. Coastal brown ants and Argentine ants run dozens of connected nests across a property and beyond it, so the question is never just where it is but how far it goes.
What looks like a queue is a chemical road. Each worker reinforces it on the way back, so the trail gets stronger the better the food is - and re-forms along the same skirting the moment the cleaning dries.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

Shiny, black and small - Sydney's most common indoor ant. Trails follow skirting boards, window frames and power cables back to nests in wall voids, roof spaces or garden edges. Sweet baits work well on it.

Small brown ants that include a bigger-headed soldier caste. Sandy soil pushed up between pavers and along slab edges gives them away. Colonies run to many nests, and oil-based granular bait is what works.

Dull brown, small, and noticeable for the thickness and speed of its trails. Multi-queen nests connect to neighbouring ones, which is how an infestation covers several properties. Repellents make it markedly worse.

Big ants, usually out after dark, nesting in soil, hollow trees and timber that has gone soft or damp. They are not the structural threat their overseas relatives are, but finding one in a wall usually means there is a leak behind it.

From an Elite job - gel bait set down on a live trail. The ants feed and carry it back to the nest, which is why we ask you not to wipe or spray that trail afterwards.
Where ants appear usually tells us where the nest is and which species we are dealing with.
Ants entering from the external wall point to a cavity or garden-edge nest. Finding that entry is the first step.
Loose fine soil along paving, driveway joints and the slab edge means coastal brown ants have nested underneath.
Warmth is what draws them into switches and electrical fittings. Never spray into a power point - tell us instead and we will treat it safely.
Swarms of winged ants in spring and summer are mating flights. Seen indoors, they can mean a mature colony inside the building.
Trails around the shower, vanity or toilet often mean moisture in the wall or a colony drinking from a slow leak.
Bull ants and jumper ants nest in the lawn and garden beds. The sting is genuinely painful and in some people causes a serious allergic reaction.

Argentine ants and a number of house ants carry multiple queens. Spray them with a repellent and a queen plus a few hundred workers simply moves out and starts again nearby.
Repellent means detectable, and detectable means avoided. Non-repellent products let foragers walk through and transfer the active to the rest of the nest.
Bait is only taken if it matches what the colony wants right now. Their preference moves between sugar and protein as the brood changes, so we test and switch baits accordingly.
Bait takes days to work through a colony. If you spray the trail the day after we leave, you kill the couriers. Our blog explains budding in more detail.
Tracing first, then baits and non-repellent products that do the work after we leave.
We identify the ant and follow trails back to entry points and nests in walls, paving, garden edges and roof spaces.
Before committing, we offer a little of each bait type and let the colony tell us which one it is on.
Indoor placements are gel on the trail - skirting, window frames, travel routes - sited away from children and pets.
We treat the foundation line, weep holes, door frames and paths with a non-repellent so incoming ants carry it with them.
For nests beneath pavers and in lawn edges - typically coastal brown ants - we use granular bait or treat the nest directly.
Written summary, instructions on what not to spray, and a 6-month warranty covering the general treatment.
The same bait does not suit every ant. This is how we choose.
| Species | Usually feeding on | Treatment approach | Common mistake |
|---|---|---|---|
| Black house ant | Mostly sweet liquids and honeydew, with protein demand during brood rearing | Gel bait along the trail, plus non-repellent treatment to weep holes and door frames | Daily detergent wiping of trails - it moves the foraging rather than stopping it |
| Coastal brown ant | Protein and oil | Oil-based granular bait applied to paving and lawn edges | Pouring insecticide into one pile and assuming that was the colony |
| Argentine ant | Sugars primarily, sometimes protein | Slow-acting baits combined with non-repellent treatment across the boundary | A repellent barrier, which splits nests that hold many queens |
| Sugar ants (Camponotus) | Insects and sweet foods, taken mainly at night | A night inspection of the trails, bait near the nest, and moisture in timber repaired | Daytime-only treatment, which misses them entirely |
| Bull ants and jumper ants | Outdoor feeders on insects and nectar | Direct treatment of the nest in the lawn or garden bed | Opening the nest up by hand and being stung for it |
| Time of year | What is happening | What to watch for |
|---|---|---|
| Early spring (Sept to Oct) | Activity resumes and brood rearing starts, so the colony wants protein | Trails appearing indoors again, and fresh sand piles in the paving |
| Late spring to summer (Nov to Feb) | Foraging at its height, and mating flights whenever it turns warm and humid | Winged ants indoors, and much heavier trails after storms and heatwaves |
| Autumn (Mar to May) | Colonies reach full size and start stocking up ahead of the cold | Trails heading for the pantry and the pet food bowl |
| Winter (Jun to Aug) | Outdoor foraging slows right down while nests in heated walls continue | Ants showing up by heaters, hot water services and in kitchens |
Most failed ant treatments come down to what happens in the week after.
Ants protecting aphids on a Birrong citrus or gardenia will keep that trail running all season. It is a garden problem presenting as a kitchen one.
Winter does not kill the colony, it just slows it. The nest under a Birrong path in July is the same nest that produces the trail in October.
Nests under paving are sheltered, warm and almost impossible to flood out. They need bait placed at the active entrances, not a hose.
Trails are traced to the colony, not just sprayed where you saw them.
The bait is chosen for the species and the time of year - sweet, protein or oil-based.
Sprays that scatter a colony are avoided entirely in favour of non-repellents the ants deliver themselves.
A general ant treatment carries 6 months of cover - if they return inside it, so do we.

Same-day attendance is usually available. Our Canterbury-Bankstown technicians cover Birrong daily, and you get a confirmed arrival time when you book.
Joined housing is the reason. Where walls, roof voids and sub-floors are continuous between properties, ants are a street-level problem rather than a house-level one.
Older joined housing. The treatment takes account of shared walls, continuous sub-floors and roof voids that run between properties.
We do. A lot of our Birrong work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
It is, applied properly. We put product into cracks, voids and stations rather than across open surfaces, and we will tell you what to stay off and for how long before we leave.
Generally no. We will tell you on arrival if any part of the job means keeping out of a room for a while, so there are no surprises.
Most ant control jobs in a Birrong home take between one and two hours on site, depending on the size of the property and how much of it is affected.
Every general treatment carries a 6-month warranty. If activity continues past the expected period, call us and we will come back.
