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.

Local technicians, fixed prices and a written report for every job in Fairfield.
Our South West Sydney technicians cover Fairfield and the rest of 2165 as a matter of course - it is only about 23.3 km west of the city. We run Fairfield on a regular route, and same-day attendance is usually available.
If you are near Lennox Reserve, Neeta City Shopping Centre or Fairfield station, that is ground we cover constantly - it is the busiest part of Fairfield for us.
Liverpool, Fairfield and Cumberland is the council area for Fairfield, and we treat Yennora, Fairfield Heights and Fairfield East on the same schedule. On a newer estate the houses are near-identical and tightly spaced, which means a problem in one tends to turn up in the ones either side.
What we see in Fairfield is newer homes on small blocks where next door has the same problem. Describing it accurately when you book saves a second visit.
Our Fairfield runs also take in Crescent Park and the area near Fairfield Leisure Centre, so the whole postcode is served.
Your appointment is confirmed the day before with a real arrival time. Because Yennora and Fairfield Heights are covered on the same round, 2165 often has an earlier slot available.
Coastal brown ants, black house ants and odorous house ants all behave differently and all turn up around Fairfield. We identify before we bait rather than putting down a general-purpose product and hoping.
After heavy rain the opposite happens - flooded nests push colonies up and inside. Both extremes send ants into Fairfield houses for different reasons.
Several of the species we treat around Fairfield are polydomous - one colony spread across many nests. Treating the nest you found leaves the rest of it working, which is why we look for the extent before we choose a product.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

Small and shiny black. It is the usual kitchen ant here, trailing along skirting boards, window frames and power cables from nests in wall voids, roof spaces and the garden edge, and it takes sweet bait easily.

Minute brown ants with larger-headed soldiers among them. Fine sand in paving joints, at slab edges and in grout is the tell. Because a colony holds many nests, oil-based granular baits are the right approach.

Small, dull brown and fast-moving in thick trails. Nests hold many queens and connect with neighbouring nests, so infestations can stretch across several properties. Repellent sprays are especially counter-productive with this species.

These are the large night-active ants that nest in soil, hollow trees and timber that has softened with damp. Structural damage is uncommon in Australia, but a wall nest points to a leak worth chasing.

Where ants appear usually tells us where the nest is and which species we are dealing with.
A trail coming in from the external wall normally means a nest in the cavity or at the garden edge, and that entry point is where the tracing begins.
If fine soil keeps appearing in the paving joints and along the drive, coastal brown ants are nesting beneath it.
They go into switches and appliances for the warmth. Keep insecticide out of power points and tell us, so it can be treated 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.
These are the bull ants and jumper ants nesting in lawns and beds - a painful sting, and a risk of serious allergic reaction for some.

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.
Ants can detect a supermarket spray and will simply route around it. A professional non-repellent is undetectable, so they walk through it and carry the active home to the colony.
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.
It takes days for bait to move through a colony. Spraying the trail the day after our visit kills the very ants delivering it - our blog explains budding in more detail.
Tracing first, then baits and non-repellent products that do the work after we leave.
Species confirmed, then trails traced to entry points and to the nests - walls, paving, garden edges, roof space.
Before committing, we offer a little of each bait type and let the colony tell us which one it is on.
Inside, gel bait follows the trails: window frames, skirting, the routes they already use, always placed where children and pets cannot get to it.
Outside, a non-repellent goes around the foundation, weep holes, door frames and paths, so ants coming in pick it up on the way.
Granular bait, or direct nest treatment, for the coastal brown ant nests under paving and at lawn edges.
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 | Sugary liquids and honeydew, plus protein when raising brood | Sweet gel bait on trails, non-repellent perimeter at weep holes and frames | Wiping trails with detergent daily, which keeps the colony foraging elsewhere |
| 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 | Chiefly sugars, with protein at intervals | Slow-release baits plus a non-repellent treatment along the property line | Repellent sprays at the boundary, which make a multi-queen colony bud |
| Sugar ants (Camponotus) | Sweet foods and insects, mostly at night | Night-time trail inspection, bait near the nest, fix moisture in timber | Treating only in daylight when the ants are not active |
| Bull ants and jumper ants | Insects and nectar outdoors | Direct nest treatment in lawns and garden beds | Digging into the nest by hand and getting stung |
| Time of year | What is happening | What to watch for |
|---|---|---|
| Early spring (Sept to Oct) | The colony restarts and begins brood production, raising its protein needs | First trails inside, and sandy soil showing up in paving joints |
| Late spring to summer (Nov to Feb) | Peak activity, with swarming flights triggered by warm humid conditions | Flying ants, and trails that thicken noticeably after storms and heat |
| Autumn (Mar to May) | Colonies are at full size and stock up before cooler weather | Trails into pantries and pet food |
| Winter (Jun to Aug) | Outdoor activity slows, but nests in heated walls keep going | Ants around heaters, hot water units and kitchens |
Most failed ant treatments come down to what happens in the week after.
Mulch against the wall, a shrub touching the eaves and a damp garden bed along the footings all put ants within reach of the building. In Fairfield we routinely find the colony is in the garden, not the house.
Food premises need bait placement that will not contaminate, and records of what was used where. That is a different job from a domestic callout.
If a trail runs up a shrub rather than into the house, the colony is farming aphids or scale for honeydew. Treating indoors will not stop it; the plant has to be dealt with too.
Trails lead somewhere, so we follow them to the colony instead of spraying the sighting.
Which bait we use depends on the ant and the season: sweet, protein or oil-based.
We use non-repellents the foragers carry back, not sprays that split the colony up.
Six months of warranty on a general ant treatment, and a return visit if they come back inside it.

Same-day attendance is usually available. Fairfield sits roughly 23.3 km west of the CBD, inside our South West Sydney run, so we book a time and keep to it.
Estates are built fast and close. Shared fence lines, narrow side access and uniform construction mean ants rarely stay at just one address.
Modern detached homes on compact lots, usually slab on ground, so the perimeter and the entry points do most of the work.
We do. A lot of our Fairfield 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.
Usually not. Most ant control work is done with you there, and anything that needs the room vacated is for a short period we will tell you about beforehand.
Allow one to two hours for a typical Fairfield property. Larger homes, or ones where the problem has spread, take longer and we will say so when we quote.
Every general treatment carries a 6-month warranty. Call us if activity picks up again and we will arrange the return visit.
We do. Fairfield and Yennora, Fairfield Heights, Fairfield East and Canley Vale are all on the same route, which helps if you own more than one property in the area.
