Budding splits the colony
A repellent does not kill a multi-queen colony, it divides it. A queen and several hundred workers shift to a new site, leaving you with two nests instead of one.

Postcode 2158 covers Middle Dural and the streets immediately around it. At about 30.9 km north-west of the CBD it falls in the Hills District, where we have vans out daily. We cover Middle Dural on scheduled runs through the Hills District, and we will give you a firm time rather than a window.
Kenthurst Park is the part of Middle Dural we attend most often.
Our runs through Middle Dural also take in Galston, Arcadia and Kenthurst. Backing onto bush means re-entry is the issue, so proofing and the perimeter do the real work here.
Around Middle Dural the pattern is fairly consistent: properties where the fence line matters as much as the kitchen. Tell us which it is on the phone and we will come prepared for it.
All of 2158 falls inside the area we service.
We confirm your slot the day before and arrive at a stated time. Galston and Arcadia sit on the same run, so earlier appointments in 2158 come up regularly.
Indoor nests sit in wall cavities, behind splashbacks, under baths and in roof insulation. Finding them is most of the work on a Middle Dural job.
A colony can occupy a garden bed, a paving slab and a wall cavity at once. That is why a single treated nest in Middle Dural changes very little on its own.
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 Middle Dural 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, 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.

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 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.

Large ants, often active at night, that nest in soil, hollow trees and softened or damp timber. Unlike the notorious overseas species they are rarely a structural pest, but a nest in a wall often points to a leak worth fixing.

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.
Ants nesting in switches and electrical fittings are drawn to the warmth. Do not spray into power points; tell us so we can treat safely.
Mating flights produce the winged swarms you see in spring and summer. Finding them indoors suggests a mature colony inside rather than outside.
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.
These are the bull ants and jumper ants nesting in lawns and beds - a painful sting, and a risk of serious allergic reaction for some.

A repellent does not kill a multi-queen colony, it divides it. A queen and several hundred workers shift to a new site, leaving you with two nests instead of one.
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.
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 identify the ant and follow trails back to entry points and nests in walls, paving, garden edges and roof spaces.
A test with small amounts of each bait type - sweet, protein, oil-based - tells us what the colony wants at this point in its cycle.
Gel bait goes along trails, window frames and skirting where ants travel, out of reach of children and pets.
The perimeter gets a non-repellent product - foundation, weep holes, door frames, paths - which intercepts ants before they are inside.
Granular bait, or direct nest treatment, for the coastal brown ant nests under paving and at lawn edges.
The job ends with a written summary, advice on what to avoid spraying, and a 6-month warranty.
The same bait does not suit every ant. This is how we choose.
| Species | Usually feeding on | Treatment approach | Common mistake |
|---|---|---|---|
| Black house ant | Sugary liquids and honeydew, plus protein when raising brood | Sweet gel bait on trails, non-repellent perimeter at weep holes and frames | Wiping trails with detergent daily, which keeps the colony foraging elsewhere |
| 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 | 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) | Sweet foods and insects, mostly at night | Night-time trail inspection, bait near the nest, fix moisture in timber | Treating only in daylight when the ants are not active |
| Bull ants and jumper ants | Nectar and insects, outdoors | Treating the nest directly where it sits in lawn or garden bed | Digging the nest out by hand, which is how people get 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) | 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) | Full colony size, and foraging to build stores before it cools | Pantry trails, and ants on the 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.
Ants in the cavity of a Middle Dural house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
A single trail across a Middle Dural prep bench during an inspection is enough to cause a problem. The program is built to prevent that rather than react to it.
The Hills District 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.
We follow the trail back to the colony rather than treating the spot where you noticed it.
The bait is chosen for the species and the time of year - sweet, protein or oil-based.
Non-repellent products only - they are taken back to the nest rather than scattering it.
If ants return within 6 months of a general treatment, we return at no charge.

We cover it on scheduled runs, so a day's notice gets you the best slot. We are about 30.9 km north-west of the city here, and Middle Dural is covered by the Hills District team.
Properties on a bush edge get re-supplied continuously. That is why our work in Middle Dural is as much about the fence line and the perimeter as the inside of the house.
Detached houses on larger blocks with bush on a boundary, so the fence line and perimeter matter as much as the interior.
We do. A lot of our Middle Dural 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, applied correctly. Products are registered for this use, placed out of reach rather than across open surfaces, and you will know what to stay off and for how long.
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.
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. Ring us if activity picks up again inside that period and we will arrange the return.
We cover the whole of Middle Dural, from the streets around Kenthurst Park out to the suburb boundary and on into Galston.
