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 Cherrybrook sits, who covers it and what it costs.
Postcode 2126 covers Cherrybrook and the streets immediately around it. At about 22 km north-west of the CBD it falls in the Upper North Shore, where we have vans out daily. We run Cherrybrook on a regular route, and same-day attendance is usually available.
Around Cherrybrook we work the pockets near Cherrybrook Village, Cherrybrook station and Roslyn Park most often, so the van is rarely far away when a job comes in.
Ku-ring-gai and Hornsby is the council area for Cherrybrook, and we treat West Pennant Hills, Westleigh and Pennant Hills on the same schedule. Backing onto bush means re-entry is the issue, so proofing and the perimeter do the real work here.
Around Cherrybrook 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.
We cover the remainder of 2126 as well, from Edward Bennett Oval through to Dural Nature Reserve.
When you book, we confirm the 2126 run the day before and give you an arrival time rather than a window. If we are already out at West Pennant Hills or Westleigh that morning, we will usually offer you the earlier slot.
People expect a single nest. Coastal brown ants and Argentine ants run dozens of connected nests across a property and beyond it, so the question is never just where it is but how far it goes.
If there are ants running up a shrub beside a Cherrybrook house, look for scale or aphids on it. They are farming, and that food source is what sustains the colony.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Cherrybrook kitchen is the difference between a result and a wasted visit.
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.

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.

An Elite photo of ants emerging from mortar. The route runs through weep holes and cracked joints straight into the wall cavity, which is the usual home for a black house ant colony.

Gel bait on a working trail, from one of our jobs. Ants feed and carry it to the nest, so wiping or spraying the trail afterwards undoes the treatment.
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.
Fine sand pushed up through paving, driveway and slab joints is coastal brown ants underneath, almost without exception.
A nest in a power point or appliance is about warmth. Spraying into electrical fittings is dangerous - tell us and we will treat it the right way.
Those spring and summer swarms of winged ants are mating flights. If they are coming out inside the house, there may be a mature colony in the building.
Trails around the shower, vanity or toilet often mean moisture in the wall or a colony drinking from a slow leak.
Bull and jumper ants live in lawn and garden-bed nests. The sting hurts, and for some people it brings on a serious allergic reaction.

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.
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.
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.
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.
Gel bait goes along trails, window frames and skirting where ants travel, out of reach of children and pets.
A non-repellent band around the footings, weep holes, door frames and paths catches ants as they come in.
Coastal brown ant nests under paving and along lawn edges get granular bait or direct treatment.
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 | 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 | 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) | 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, 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) | Activity resumes and brood rearing starts, so the colony wants protein | Trails appearing indoors again, and fresh sand piles in the paving |
| Late spring to summer (Nov to Feb) | Foraging at its height, and mating flights whenever it turns warm and humid | Winged ants indoors, and much heavier trails after storms and heatwaves |
| Autumn (Mar to May) | Colonies are at full size and stock up before cooler weather | Trails into pantries and 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 garden is usually the source. Shrubs touching the walls, mulch up against the footings and irrigated beds give a colony everything it needs within a metre of your kitchen.
Winter does not kill the colony, it just slows it. The nest under a Cherrybrook path in July is the same nest that produces the trail in October.
Brick cavities are dry, warm and undisturbed, which makes them ideal nesting. The weep hole is the doorway and it is usually where we start on a Cherrybrook job.
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 that foragers carry home, instead of sprays that scatter the colony.
General ant treatments are covered. If ants come back within 6 months, so do we.

Same-day attendance is usually available. Cherrybrook sits roughly 22 km north-west of the CBD, inside our Upper North Shore 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.
Detached houses on bush edges, where re-entry is the issue rather than the initial treatment.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across Cherrybrook 2126, and we provide the written report agents and strata managers ask for.
It is, applied properly. We put product into cracks, voids and stations rather than across open surfaces, and we will tell you what to stay off and for how long before we leave.
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.
Allow one to two hours for a typical Cherrybrook property. Larger homes, or ones where the problem has spread, take longer and we will say so when we quote.
Every general treatment carries a 6-month warranty. If it is not holding, call us - that is exactly what the warranty is for.
Yes. As well as Cherrybrook we cover West Pennant Hills, Westleigh, Pennant Hills and Beecroft on the same runs, so a job that crosses a boundary can be handled in one visit.
