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 East Lindfield sits, who covers it and what it costs.
If you are in East Lindfield or anywhere else in 2070, you are in our Upper North Shore patch, 10.9 km north of the CBD. We run East Lindfield on a regular route, and same-day attendance is usually available.
Around East Lindfield we work the pockets near Roseville Golf Course, Roseville station and Follies Park most often, so the van is rarely far away when a job comes in.
The suburb sits in the Ku-ring-gai and Hornsby area. Roseville Chase, Roseville and Lindfield are all covered on the same day, so a problem that has spread across a boundary can be handled in one visit. Bush edges keep re-supplying the problem, which is why we treat the boundary rather than only the interior.
The ant calls we take from East Lindfield are mostly properties where the fence line matters as much as the kitchen. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Our East Lindfield runs also take in Nungara Reserve and the area near Lindfield Shopping Village, so the whole postcode is served.
You get a confirmed time, not a window. We plan the 2070 run the day before, and if Roseville Chase or Roseville is on the same round there is often an earlier slot going.
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.
Several of the species we treat around East Lindfield are polydomous - one colony spread across many nests. Treating the nest you found leaves the rest of it working, which is why we look for the extent before we choose a product.
Pharaoh and some other small species nest indoors in warm voids and never go outside at all. In a East Lindfield house that changes the treatment completely - and makes spraying actively harmful, because it buds the colony.
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.

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.

Small, dull brown and fast-moving in thick trails. Nests hold many queens and connect with neighbouring nests, so infestations can stretch across several properties. Repellent sprays are especially counter-productive with this species.

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.

From an Elite job - a nest coming out of a mortar joint. Cracked mortar and weep holes open directly into the wall cavity, and that cavity is where a lot of black house ant colonies sit.

Photo from an Elite job: gel bait placed along an active trail. The ants are left to feed and carry the bait home, so we ask customers not to wipe or spray the trail afterwards.
Where ants appear usually tells us where the nest is and which species we are dealing with.
A trail in from the outside wall means the colony is in the cavity or the garden edge - the entry point is what we follow.
Fine soil pushed up along paving, driveways and slab joints is the classic sign of coastal brown ants nesting underneath.
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.
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'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.
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.
First the species, then the trails - followed back to where they enter and to nests in the wall, under paving, at garden edges or in the roof space.
We put out small quantities of sweet, protein and oil-based bait to see which the colony is actually taking today.
Inside, gel bait follows the trails: window frames, skirting, the routes they already use, always placed where children and pets cannot get to it.
Outside, a non-repellent goes around the foundation, weep holes, door frames and paths, so ants coming in pick it up on the way.
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 | Protein and oils | Oil-based granular bait on paving and lawn edges | Pouring boiling water or insecticide into one pile while dozens of nests remain |
| Argentine ant | Sugar for the most part, with periodic protein demand | Slow baits and a non-repellent applied along the property line | Using a repellent barrier spray - it divides the multi-queen colony |
| Sugar ants (Camponotus) | Sweet foods and insects, active after dark | Night trail inspection, baiting near the nest, and dealing with damp timber | Inspecting in daylight when the colony is not foraging |
| Bull ants and jumper ants | Insects and nectar outdoors | Direct nest treatment in lawns and garden beds | Digging into the nest by hand and getting stung |
| Time of year | What is happening | What to watch for |
|---|---|---|
| Early spring (Sept to Oct) | The colony restarts and begins brood production, raising its protein needs | First trails inside, and sandy soil showing up in paving joints |
| 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 foraging slows right down while nests in heated walls continue | Ants showing up by heaters, hot water services and in kitchens |
Most failed ant treatments come down to what happens in the week after.
The Upper North Shore pattern is a surge after the first warm fortnight, then steady pressure into March. A colony treated in September is a fraction of the job it is in January.
Anywhere in 2070, or over toward Roseville Chase, is inside the area we treat at the same price.
Ants in the cavity of a East Lindfield house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
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.
We use non-repellents the foragers carry back, not sprays that split the colony up.
General ant treatments are covered. If ants come back within 6 months, so do we.

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 East Lindfield 2070. Every general treatment carries a 6-month warranty.
Same-day attendance is usually available. We are about 10.9 km north of the city here, and East Lindfield is covered by the Upper North Shore team.
Properties on a bush edge get re-supplied continuously. That is why our work in East Lindfield is as much about the fence line and the perimeter as the inside of the house.
Homes with sub-floors and roof voids backing onto reserve - we inspect all three plus the boundary.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across East Lindfield 2070, and we provide the written report agents and strata managers ask for.
It is, provided the instructions are followed. We will tell you what to keep clear of and for how long before we leave. Let us know about children, pets or fish tanks when you book.
Generally no. We will tell you on arrival if any part of the job means keeping out of a room for a while, so there are no surprises.
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. So if they turn up again within the warranty, ring us and we will attend.
We cover the whole of East Lindfield, from the streets around Nungara Reserve out to the suburb boundary and on into Roseville Chase.
