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 Bardwell Valley sits, who covers it and what it costs.
Bardwell Valley is part of the St George & Bayside, 10.3 km or so south-west of the GPO, and 2207 is a postcode we know well. We run Bardwell Valley on a regular route, and same-day attendance is usually available.
Around Bardwell Valley we work the pockets near Bardwell Valley Golf Course, Bardwell Park station and Shepherd Parade Reserve most often, so the van is rarely far away when a job comes in.
Georges River and Bayside is the council area for Bardwell Valley, and we treat Bardwell Park, Turrella and Arncliffe on the same schedule. Salt air and sandy ground keep sub-floors damp here, and damp is what sustains a population.
Most Bardwell Valley bookings come in as apartments where the problem is really in the building rather than the flat. Say which one applies when you call 1300 313 373 and the technician will have the right products on the van.
The whole of 2207 is covered, Wolli Creek Regional Park included.
You get a confirmed time, not a window. We plan the 2207 run the day before, and if Bardwell Park or Turrella is on the same round there is often an earlier slot going.
A colony can occupy a garden bed, a paving slab and a wall cavity at once. That is why a single treated nest in Bardwell Valley changes very little on its own.
If there are ants running up a shrub beside a Bardwell Valley house, look for scale or aphids on it. They are farming, and that food source is what sustains the colony.
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.

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 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.

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.

An Elite photo of gel bait on an active trail. The whole point is letting them feed and take it home, so the trail must be left alone once we have treated it.
Where ants appear usually tells us where the nest is and which species we are dealing with.
Ants arriving from the outside wall usually nest in the cavity or garden edge. The entry point is where we start tracing.
Fine sand pushed up through paving, driveway and slab joints is coastal brown ants underneath, almost without exception.
A nest in a power point or appliance is about warmth. Spraying into electrical fittings is dangerous - tell us and we will treat it the right way.
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.
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.
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.
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.
Gel is placed on the trails themselves - along window frames and skirting boards - and positioned out of reach of 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.

The same bait does not suit every ant. This is how we choose.
| Species | Usually feeding on | Treatment approach | Common mistake |
|---|---|---|---|
| Black house ant | Honeydew and sugary liquids, switching to protein when there is brood | Sweet gel on active trails and a non-repellent perimeter at frames and weep holes | Washing the trail down each day, which only relocates the foraging route |
| 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) | Nocturnal, on sweet foods and insects | Trails inspected at night, bait placed near the nest, timber moisture fixed | Only ever treating during the day, when there is nothing to see |
| Bull ants and jumper ants | Insects and nectar, always outside | The nest itself is treated directly, in lawn or garden bed | Hand-digging a nest, which reliably ends in stings |
| Time of year | What is happening | What to watch for |
|---|---|---|
| Early spring (Sept to Oct) | Colonies wake up and start raising new brood, so protein demand rises | First trails indoors, sand piles reappearing in paving |
| 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) | 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.
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.
For a Bardwell Valley 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.
After sustained rain in Bardwell Valley we get a run of calls, and the cause is consistent: shallow nests waterlogged, the colony moved into a wall cavity or subfloor to dry out.
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.
Nothing repellent, because that causes budding. Non-repellent products get carried home instead.
If ants return within 6 months of a general treatment, we return at no charge.

Same-day attendance is usually available. We are about 10.3 km south-west of the city here, and Bardwell Valley is covered by the St George & Bayside team.
Humidity close to the coast does not fall away in winter the way it does inland, so ants here get a longer active season than they would further west.
Apartments near the beach and houses behind them. Either way the sub-floor and the lower level are the parts that matter.
We do all of those. A good share of the Bardwell Valley jobs we run are tenanted or strata properties, so the written record comes as standard.
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.
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.
Between one and two hours covers the majority of jobs. We do not book so tightly that a technician has to cut a job short.
Every general treatment carries a 6-month warranty. A return visit inside that period does not cost you anything.
Yes - we work right across the Georges River and Bayside area, which takes in Bardwell Valley and the suburbs around it.
