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 Bundeena sits, who covers it and what it costs.
Our Sutherland Shire technicians cover Bundeena and the rest of 2230 as a matter of course - it is only about 24.5 km south of the city. We run Bundeena on a regular route, and same-day attendance is usually available.
The Bundeena addresses we attend cluster around Berenice Forster Park and Bundeena Reserve. Horderns Beach is another part of the suburb we are called to often.
Under Sutherland Shire, we cover Bundeena and Burraneer, Maianbar and Cronulla alike. Bush edges keep re-supplying the problem, which is why we treat the boundary rather than only the interior.
Around Bundeena the pattern is fairly consistent: homes on sloping blocks with a sub-floor and bush on the boundary. Tell us which it is on the phone and we will come prepared for it.
The whole of 2230 is on our regular run.
When you book, we confirm the 2230 run the day before and give you an arrival time rather than a window. If we are already out at Burraneer or Maianbar that morning, we will usually offer you the earlier slot.
Ants in timber are a symptom. They do not create the damp, they move into timber the damp has already softened, so the leak matters more than the ants.
A colony's preference also shifts with the season. Spring brood-rearing wants protein; later in summer the same Bundeena colony wants sugars.
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 Bundeena 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.

Small brown ants that include a bigger-headed soldier caste. Sandy soil pushed up between pavers and along slab edges gives them away. Colonies run to many nests, and oil-based granular bait is what works.

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.

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.

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.
When they come in from the outside wall, the nest is usually in the cavity or just outside in the garden. We work back from the entry point.
Fine soil pushed up along paving, driveways and slab joints is the classic sign of coastal brown ants nesting underneath.
They go into switches and appliances for the warmth. Keep insecticide out of power points and tell us, so it can be treated safely.
Mating flights produce the winged swarms you see in spring and summer. Finding them indoors suggests a mature colony inside rather than outside.
Bathroom trails around the shower, basin or toilet normally mean water: damp in the wall cavity, or a slow leak supplying the colony.
Bull ants and jumper ants nest in lawns and garden beds. Their stings hurt and can cause serious allergic reactions in some people.

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.
Retail sprays repel: the ants know they are there and go round. Professional non-repellents do not register, so the foragers deliver the active to the colony for us.
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.
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.
Species confirmed, then trails traced to entry points and to the nests - walls, paving, garden edges, roof space.
Small amounts of sweet, protein and oil-based bait show what the colony is feeding on right now.
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.
You get a summary, advice on what not to spray, 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 | 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 | Oils and protein rather than sugars | Granular bait with an oil base, spread on paving and at the lawn edge | Boiling water down one hole - there are dozens of other nests |
| 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) | 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 | Nectar and insects taken outdoors | Direct nest treatment wherever it is in the lawn or beds | Trying to dig it out yourself and getting stung |
| 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) | Peak foraging, mating flights after warm humid weather | Winged ants, heavy trails after storms and 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.
After sustained rain in Bundeena 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.
Ants in the cavity of a Bundeena house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
A branch touching the roof is a bridge. Mulch banked against brickwork is harbourage. Most of what brings ants inside a Bundeena home is in the garden immediately around it.
Trails lead somewhere, so we follow them to the colony instead of spraying the sighting.
Sweet, protein or oil-based, picked to suit the ant and the point in the season.
Non-repellent products only - they are taken back to the nest rather than scattering it.
Six months of warranty on a general ant treatment, and a return visit if they come back inside it.

Get a Free QuoteAnt treatment starts from $89. The fixed price depends on the size of the property and how far the problem has spread, and we confirm it before we start - there is no call-out fee in Bundeena 2230. Every general treatment carries a 6-month warranty.
Same-day attendance is usually available. Bundeena sits roughly 24.5 km south of the CBD, inside our Sutherland Shire run, so we book a time and keep to it.
Leaf litter, fallen timber and undisturbed ground right up to the boundary keep ants populations healthy next door to you, whatever you do indoors.
Mostly detached housing backing onto reserve. Proofing and the perimeter are what actually hold here.
Yes. Houses, townhouses, units, strata common property, rentals and commercial sites in Bundeena 2230 are all part of what we do, and the paperwork is the kind agents accept.
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 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.
Usually between one and two hours on site. Bigger properties and heavier infestations take more, and that is included in the quote rather than added afterwards.
Every general treatment carries a 6-month warranty. A return visit within the warranty period costs you nothing.
Yes - we work right across the Sutherland Shire area, which takes in Bundeena and the suburbs around it.
