Budding splits the colony
Multi-queen species - Argentine ants and several house ants among them - react to a repellent by splitting. A queen and a few hundred workers relocate, and one colony becomes two.

Where Barangaroo sits, who covers it and what it costs.
Our Sydney CBD & Inner City technicians cover Barangaroo and the rest of 2000 as a matter of course - it is only about 0.9 km north-west of the city. Our technicians are through Barangaroo most days, so same-day attendance is usually available.
If you are near Wynyard station, Barangaroo station or Wynyard Park, that is ground we cover constantly - it is the busiest part of Barangaroo for us.
Millers Point, The Rocks and Pyrmont are all on the same route as Barangaroo. Nearly everything here is apartments, so the question is always whether the problem is in your flat or in the building - the risers, the bin room, the wall cavities between lots.
What we see in Barangaroo is units in towers where the kitchen backs onto shared services. Describing it accurately when you book saves a second visit.
Beyond that we are regularly around Observatory Hill Park, and out as far as Westfield Sydney. If you are anywhere in 2000, you are inside the area we run.
We confirm your slot the day before and arrive at a stated time. Millers Point and The Rocks sit on the same run, so earlier appointments in 2000 come up regularly.
Coastal brown ants, black house ants and odorous house ants all behave differently and all turn up around Barangaroo. We identify before we bait rather than putting down a general-purpose product and hoping.
Many ants get most of their sugar from honeydew - the secretion of aphids and scale insects they actively protect on garden plants. A Barangaroo garden with a scale problem is feeding the ant colony that then comes indoors.
Indoor nests sit in wall cavities, behind splashbacks, under baths and in roof insulation. Finding them is most of the work on a Barangaroo job.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

Small, shiny and black, and one of the most common kitchen ants in Sydney. It trails along skirting boards, window frames and power cables, and nests in wall voids, roof spaces and garden edges. It readily takes sweet baits.

Tiny brown ants with a larger-headed soldier caste. The giveaway is loose sandy soil pushed up between pavers, along slab edges and in grout. Colonies are large with many nests, and oil-based granular baits work well.

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.

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.

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 entering from the external wall point to a cavity or garden-edge nest. Finding that entry is the first step.
If fine soil keeps appearing in the paving joints and along the drive, coastal brown ants are nesting beneath it.
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.
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.

The difference matters. Retail sprays are repellent - ants sense them and avoid the treated area. Non-repellent products cannot be detected, so foragers cross them, pick up the active and take it back to the nest.
If the bait is not what they want today, they will walk past it. Preference moves between sugar and protein with brood demand, so we test and change as needed.
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 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.
We put out small quantities of sweet, protein and oil-based bait to see which the colony is actually taking today.
Gel is placed on the trails themselves - along window frames and skirting boards - and positioned out of reach of children and pets.
A non-repellent treatment around the foundation, weep holes, door frames and paths intercepts ants coming in.
For nests beneath pavers and in lawn edges - typically coastal brown ants - we use granular bait or treat the nest directly.
Written summary, instructions on what not to spray, and a 6-month warranty covering 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 | Mostly sweet liquids and honeydew, with protein demand during brood rearing | Gel bait along the trail, plus non-repellent treatment to weep holes and door frames | Daily detergent wiping of trails - it moves the foraging rather than stopping it |
| 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 | 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 | Outdoor feeders on insects and nectar | Direct treatment of the nest in the lawn or garden bed | Opening the nest up by hand and being stung for it |
| 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 foraging, mating flights after warm humid weather | Winged ants, heavy trails after storms and heatwaves |
| Autumn (Mar to May) | The colony is at its largest and laying in stores before winter | Trails running into pantries and to pet food |
| Winter (Jun to Aug) | Outside activity drops away, though nests in warm wall cavities carry on | Ants near heaters, hot water units and in the kitchen |
Most failed ant treatments come down to what happens in the week after.
After sustained rain in Barangaroo 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.
A branch touching the roof is a bridge. Mulch banked against brickwork is harbourage. Most of what brings ants inside a Barangaroo home is in the garden immediately around it.
Activity climbs from early spring as colonies start brood-rearing, peaks through the hot months and tails off in autumn. Treating in early spring around Barangaroo gets ahead of it rather than chasing it.
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.

Same-day attendance is usually available. Our Sydney CBD & Inner City technicians cover Barangaroo daily, and you get a confirmed arrival time when you book.
Density is the whole answer. Shared walls, shared risers and shared bins mean ants move between lots freely, which is why single-unit treatments here often do not hold.
Apartments throughout, which means treating your lot and scoping the building where the pattern points at common property.
We do all of those. A good share of the Barangaroo jobs we run are tenanted or strata properties, so the written record comes as standard.
It is, as long as you follow what we tell you on the day - usually keeping off treated surfaces for a couple of hours. Let us know at booking about young children, pets or an aquarium.
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.
We cover the whole of Barangaroo, from the streets around Westfield Sydney out to the suburb boundary and on into Millers Point.
