Budding splits the colony
Species with many queens, such as Argentine ants and several house ants, respond to a repellent spray by relocating. A few hundred workers and a queen move to a new spot, and you now have two colonies instead of one.

Where Doonside sits, who covers it and what it costs.
If you are in Doonside or anywhere else in 2767, you are in our Blacktown & Mount Druitt patch, 33.5 km west of the CBD. We cover Doonside on scheduled runs through the Blacktown & Mount Druitt, and we will give you a firm time rather than a window.
Most weeks we are somewhere between Doonside station and Bert Saunders Reserve in Doonside, and Woodcroft Shopping Village is close enough to be on the same run.
We work under the Blacktown City area here, and Woodcroft, Glendenning and Rooty Hill are all on the same route, which matters when ant problems are moving between adjoining properties. 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.
The ant calls we take from Doonside are mostly newer homes on small blocks where next door has the same problem. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Every part of 2767 is covered as standard.
Bookings for 2767 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Woodcroft and Glendenning often share the same run, which is how earlier slots come up.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Doonside kitchen is the difference between a result and a wasted visit.
Pharaoh and some other small species nest indoors in warm voids and never go outside at all. In a Doonside house that changes the treatment completely - and makes spraying actively harmful, because it buds the colony.
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 Doonside kitchen removes the smell for a few hours, not the colony that laid it.
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.

A small, matt brown ant that moves quickly in heavy trails. Its nests have multiple queens and link up with others nearby, so the problem often spans several properties. Repellent spray is the worst thing to use on it.

Large ants, often active at night, that nest in soil, hollow trees and softened or damp timber. Unlike the notorious overseas species they are rarely a structural pest, but a nest in a wall often points to a leak worth fixing.

An Elite photo of ants emerging from mortar. The route runs through weep holes and cracked joints straight into the wall cavity, which is the usual home for a black house ant colony.

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.
Fine sand pushed up through paving, driveway and slab joints is coastal brown ants underneath, almost without exception.
Electrical fittings and switches stay warm, which is why ants nest in them. Do not spray into them; let us know and we will handle it properly.
Those spring and summer swarms of winged ants are mating flights. If they are coming out inside the house, there may be a mature colony in the building.
Trails in the bathroom point to water in the wall or a slow leak the ants have found.
Bull ants and jumper ants nest in lawns and garden beds. Their stings hurt and can cause serious allergic reactions in some people.

Species with many queens, such as Argentine ants and several house ants, respond to a repellent spray by relocating. A few hundred workers and a queen move to a new spot, and you now have two colonies instead of one.
Supermarket sprays are repellent: ants detect them and walk around them. Professional non-repellent products are not detected, so foragers walk through, pick up the active and carry it back to nest mates.
A colony's appetite shifts between sugar and protein with the brood cycle. Bait only works when it matches, which is why we test preferences on site.
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.
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.
A non-repellent band around the footings, weep holes, door frames and paths catches ants as they come in.
Under-paver and lawn-edge nests are handled with granular bait, or treated directly where that is better.
You receive the job summary in writing, guidance on what to leave alone, and 6 months of warranty on 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 | Sugars and honeydew, turning to protein while brood is being raised | Sweet gel on the trails themselves, with a non-repellent at weep holes and frames | Cleaning the trail off every day, which just sends them foraging somewhere else |
| 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 | Mainly sugars, protein at some points in the cycle | Slow-acting bait with a non-repellent treatment right across the boundary | Spraying a repellent barrier, which causes a multi-queen nest to 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 | 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) | Colonies become active and start on brood, which shifts them onto protein | Early indoor trails, and sand piles returning to 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) | Full colony size, and foraging to build stores before it cools | Pantry trails, and ants on the 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.
Ants in the cavity of a Doonside house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
For a Doonside cafe or kitchen, ants are a compliance finding. We run a documented program with monitoring points and reports your auditor will accept rather than a one-off spray.
The garden is usually the source. Shrubs touching the walls, mulch up against the footings and irrigated beds give a colony everything it needs within a metre of your kitchen.
Finding the nest is the job - following the trail to it, not treating the visible end of it.
Sweet, protein or oil-based, picked to suit the ant and the point in the season.
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.
