Budding splits the colony
Multi-queen species - Argentine ants and several house ants among them - react to a repellent by splitting. A queen and a few hundred workers relocate, and one colony becomes two.

We treat ants right across 2570. Cobbitty is roughly 51.2 km west of the city, which puts it well inside the Macarthur run our technicians work. We travel out to Cobbitty on planned runs through the Macarthur, so booking a day ahead gets you the best slot.
Around Cobbitty we are most often working near Camden Village Court.
Under Campbelltown and Camden, we cover Cobbitty and Ellis Lane, Kirkham and Camden alike. Newer estate housing sits close together on small blocks, so what happens next door matters. We check the boundary and the fence line, not just the house.
Cobbitty jobs tend to be recently built homes where the activity started at the boundary. Let us know which when you ring and we will plan the visit around it.
The whole of 2570 is on our regular run.
Your appointment is confirmed the day before with a real arrival time. Because Ellis Lane and Kirkham are covered on the same round, 2570 often has an earlier slot available.
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.
Ants lay a pheromone trail that other workers follow, which is why the line is so precise and why it reappears in exactly the same place after you wipe it. Cleaning a Cobbitty kitchen removes the smell for a few hours, not the colony that laid it.
Indoor nests sit in wall cavities, behind splashbacks, under baths and in roof insulation. Finding them is most of the work on a Cobbitty job.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

Small, shiny and black, and one of the most common kitchen ants in Sydney. It trails along skirting boards, window frames and power cables, and nests in wall voids, roof spaces and garden edges. It readily takes sweet baits.

Tiny and brown, with a distinct large-headed soldier. The sign is loose sand appearing between pavers, along the slab edge and in grout lines. Many nests to a colony, which is why we use oil-based granular baits.

Small and flat brown in colour, running in dense fast trails. Because nests hold many queens and join with those next door, the infestation is usually bigger than one property. Never spray a repellent on it.

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.

Photo from an Elite job: an ant nest emerging from a mortar joint. Weep holes and cracked mortar lead straight into the wall cavity, which is where many black house ant colonies live.

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.
Ants nesting in switches and electrical fittings are drawn to the warmth. Do not spray into power points; tell us so we can treat safely.
Swarms of winged ants in spring and summer are mating flights. Seen indoors, they can mean a mature colony inside the building.
Bathroom trails around the shower, basin or toilet normally mean water: damp in the wall cavity, or a slow leak supplying the colony.
Bull and jumper ants live in lawn and garden-bed nests. The sting hurts, and for some people it brings on a serious allergic reaction.

The difference matters. Retail sprays are repellent - ants sense them and avoid the treated area. Non-repellent products cannot be detected, so foragers cross them, pick up the active and take it back to the nest.
A colony only takes bait if it wants that food at that moment. Ants switch between sugar and protein as their brood needs change, so we test preferences and change baits when needed.
Give it days, not hours. Bait has to be carried through the colony, and spraying the trail afterwards destroys the couriers doing that work. Our blog covers 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.
A test with small amounts of each bait type - sweet, protein, oil-based - tells us what the colony wants at this point in its cycle.
We run gel along the active trails, window frames and skirting, keeping every placement out of reach of children and animals.
Outside, a non-repellent goes around the foundation, weep holes, door frames and paths, so ants coming in pick it up on the way.

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 oily foods | Oil-based granular bait over paving and lawn margins | Attacking a single visible nest while the rest of the colony's nests carry on |
| 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, foraging after dark | Inspecting trails at night, baiting close to the nest, and fixing damp timber | Working only in daylight hours, when these ants are not out |
| Bull ants and jumper ants | Nectar and insects, outdoors | Treating the nest directly where it sits in lawn or garden bed | Digging the nest out by hand, which is how people get stung |
| 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 peaks, and warm humid spells trigger mating flights | Swarms of winged ants, and heavy trails following storms or heatwaves |
| Autumn (Mar to May) | The colony is at its largest and laying in stores before winter | Trails running into pantries and to pet food |
| Winter (Jun to Aug) | Little happening outdoors, but a nest in a heated wall stays active | Activity around heaters, the hot water unit and kitchen areas |
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 Cobbitty we routinely find the colony is in the garden, not the house.
A storm is the most reliable trigger for an indoor ant problem. Nests in soil and paving flood, and the colony relocates somewhere dry, meaning your building.
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.
We follow the trail back to the colony rather than treating the spot where you noticed it.
Sweet, protein or oil-based baits chosen for the ant and the season.
Non-repellent products only - they are taken back to the nest rather than scattering it.
A general ant treatment carries 6 months of cover - if they return inside it, so do we.

Two things drive it on an estate: compact blocks with narrow side passages, and ground that was cleared and rebuilt recently, which displaces whatever was living in it.
Newer detached homes on compact blocks, so access down the side and the shared fence line shape how we work.
We do. A lot of our Cobbitty work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
Yes, with the usual care. Everything is APVMA-registered and used to label, and we will work around pets, aquariums and anyone in the house with a respiratory condition if you tell us when you book.
In the great majority of jobs, no. If one area needs to be left for an hour or two we say so before we start rather than after.
Typically one to two hours on site. What extends it is size, access and how far the problem has gone, all of which are accounted for in the quote.
Every general treatment carries a 6-month warranty. If activity continues past the expected period, call us and we will come back.
Yes - we work right across the Campbelltown and Camden area, which takes in Cobbitty and the suburbs around it.
