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.

Our St George & Bayside technicians cover Bardwell Park and the rest of 2207 as a matter of course - it is only about 10.7 km south-west of the city. We run Bardwell Park on a regular route, and same-day attendance is usually available.
Our Bardwell Park work takes in the streets by Wolli Creek Regional Park and Bardwell Valley Golf Course, through to Bardwell Park station at the other end.
We work under the Georges River and Bayside area here, and Bardwell Valley, Turrella and Bexley North are all on the same route, which matters when ant problems are moving between adjoining properties. The coastal damp is the part that matters: sub-floors and ground-floor wet areas rarely dry out properly.
The bulk of our Bardwell Park work is unit blocks a street or two back from the water, plus the odd beachfront cafe. Mention the detail when you call 1300 313 373 - it decides how long we need on site.
The whole of 2207 is covered, Charles Daly Reserve included.
The 2207 run is set the day before and you are given an arrival time. Where Bardwell Valley and Turrella fall on the same round, we can usually bring the visit forward.
The reason the trail returns to the same spot in a Bardwell Park kitchen is that it is marked chemically. Wiping it buys hours. Treating the colony that maintains it is the only thing that ends it.
If there are ants running up a shrub beside a Bardwell Park house, look for scale or aphids on it. They are farming, and that food source is what sustains the colony.
Coastal brown ants, black house ants and odorous house ants all behave differently and all turn up around Bardwell Park. We identify before we bait rather than putting down a general-purpose product and hoping.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

The small glossy black one you find in the kitchen. It runs along skirtings, window frames and cabling, nesting in wall cavities, roof voids and the edges of garden beds, and it takes sweet bait without much persuading.

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.

Fast-moving, small and dull brown, in thick trails. Its nests are multi-queen and interconnected with neighbouring nests, so it spreads across properties - and repellent sprays accelerate exactly that.

Large and mostly nocturnal, nesting in soil, hollow trees and damp or softened timber. They rarely damage structure here, though a nest inside a wall is a reliable sign of moisture that needs attention.

Taken on an Elite job: a mortar joint with a nest behind it. Weep holes and failed mortar are a direct path into the cavity, where many black house ant colonies establish.

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.
That fine sandy soil appearing between pavers, along the driveway and at slab joints is the classic coastal brown ant sign - they are nesting below.
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.
Ant trails at the shower, vanity or toilet usually come down to moisture - either damp in the wall or a slow leak they are drinking from.
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.
Ants will ignore bait that does not suit their current needs. Because they alternate between sugar and protein depending on the brood, we test preference rather than assume.
A bait program works over days. The worst thing you can do is spray the trail once we have gone - those ants are the delivery system. See our blog on budding in more detail.
Tracing first, then baits and non-repellent products that do the work after we leave.
We work out which ant it is and follow the trails back, which is what locates nests in wall cavities, under paving, along garden edges and in roof spaces.
Sweet, protein and oil-based baits are offered in small amounts so the colony shows us its current preference.
Inside, gel bait follows the trails: window frames, skirting, the routes they already use, always placed where children and pets cannot get to it.
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.
A written summary, clear advice on what not to spray afterwards, and a 6-month 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 | Oils and protein | Granular oil-based bait across the paving and along lawn edges | Treating one sand pile with boiling water or insecticide when there are dozens more |
| Argentine ant | Sugars, with protein at times | Slow-acting baits plus non-repellent treatment across the property line | Repellent barrier sprays, which split multi-queen nests |
| 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 | 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 come out of winter and begin raising brood, which pushes protein demand up | The first indoor trails of the season, and sand reappearing between pavers |
| Late spring to summer (Nov to Feb) | The busiest foraging period, with mating flights after warm humid weather | Winged ants on the wing, and thick trails after a storm or a hot spell |
| 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) | Quiet outside, but colonies in warm wall cavities keep working | Ants around the heater, the hot water unit and the kitchen |
Most failed ant treatments come down to what happens in the week after.
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.
Winter does not kill the colony, it just slows it. The nest under a Bardwell Park path in July is the same nest that produces the trail in October.
We are around Wolli Creek Regional Park most weeks and cover every street in 2207, including the ones off the main roads.
The trail gets traced to its source. Spraying where you saw ants achieves very little.
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.
If ants return within 6 months of a general treatment, we return at no charge.

Get a Free QuoteAnt treatment starts from $89. There is no call-out charge in Bardwell Park 2207. The final number comes down to the property itself, and it is fixed before we begin. Every general treatment carries a 6-month warranty.
Same-day attendance is usually available. Our St George & Bayside technicians cover Bardwell Park daily, and you get a confirmed arrival time when you book.
Being near the water means humidity that never really drops. Sub-floors stay moist, lower levels stay cool and damp, and ants do well in both.
A mix of walk-up blocks and free-standing homes, where the lower level and the sub-floor are what we concentrate on.
We do. A lot of our Bardwell Park 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. Everything we use is registered for the purpose and applied at label rates, and we place product where people and animals do not go. Tell us about pets, aquariums or anyone with a respiratory condition at booking.
In most cases you can stay. Where an area does need to be left clear it is for a couple of hours at most, and we say so before we start.
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. A return visit within the warranty period costs you nothing.
All of them. Bardwell Park sits alongside Bardwell Valley, Turrella, Bexley North and Bexley in our coverage, and they are serviced on the same schedule.
