Budding splits the colony
Species with many queens, such as Argentine ants and several house ants, respond to a repellent spray by relocating. A few hundred workers and a queen move to a new spot, and you now have two colonies instead of one.

What we cover in Galston, and how quickly we can get there.
We treat ants right across 2159. Galston is roughly 28.8 km north-west of the city, which puts it well inside the Upper North Shore run our technicians work. We cover Galston on scheduled runs through the Upper North Shore, and we will give you a firm time rather than a window.
Around Galston we are most often working near Fagan Park.
The suburb sits in the Ku-ring-gai and Hornsby area. Middle Dural, Arcadia and Dural are all covered on the same day, so a problem that has spread across a boundary can be handled in one visit. Backing onto bush means re-entry is the issue, so proofing and the perimeter do the real work here.
What we see in Galston is houses backing onto a reserve, where the pressure is constant from outside. Describing it accurately when you book saves a second visit.
Wherever you are in 2159, you are inside the area our technicians cover.
The 2159 run is set the day before and you are given an arrival time. Where Middle Dural and Arcadia fall on the same round, we can usually bring the visit forward.
Several of the species we treat around Galston 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.
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.
Indoor nests sit in wall cavities, behind splashbacks, under baths and in roof insulation. Finding them is most of the work on a Galston job.
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.

Very small brown ants, with soldiers that have noticeably bigger heads. You spot them by the fine sandy soil pushed up through paving joints, slab edges and grout. The colonies are big and multi-nested, so oil-based granular bait is the tool.

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.

Large and mostly nocturnal, nesting in soil, hollow trees and damp or softened timber. They rarely damage structure here, though a nest inside a wall is a reliable sign of moisture that needs attention.

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.
Warmth is what draws them into switches and electrical fittings. Never spray into a power point - tell us instead and we will treat it safely.
Swarms of winged ants in spring and summer are mating flights. Seen indoors, they can mean a mature colony inside the building.
Bathroom trails around the shower, basin or toilet normally mean water: damp in the wall cavity, or a slow leak supplying the colony.
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.

Species with many queens, such as Argentine ants and several house ants, respond to a repellent spray by relocating. A few hundred workers and a queen move to a new spot, and you now have two colonies instead of one.
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.
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.
Results come over days as the bait spreads. Spray the trail the next morning and you have killed the ants that were carrying it home. 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.
Outside, a non-repellent goes around the foundation, weep holes, door frames and paths, so ants coming in pick it up on the way.
Granular bait or direct treatment for coastal brown ant nests under pavers and in 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 | 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 | 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 | 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, 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 | 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) | 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) | 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 peak in size and stock up for the cooler months | Trails into the pantry and around pet bowls |
| 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.
Our Galston runs take in Fagan Park and continue across to the Middle Dural boundary - all the same service area.
A storm is the most reliable trigger for an indoor ant problem. Nests in soil and paving flood, and the colony relocates somewhere dry, meaning your building.
Fine soil pushed up along paving joints, path edges and garden edging is excavation - there is a nest directly beneath. Around Galston that is coastal brown ants more often than not.
Trails lead somewhere, so we follow them to the colony instead of spraying the sighting.
Sweet, protein or oil-based baits chosen for the ant and the season.
Sprays that scatter a colony are avoided entirely in favour of non-repellents the ants deliver themselves.
General ant treatments are covered. If ants come back within 6 months, so do we.

Get a Free QuoteAnt treatment starts from $89. We quote on the property rather than the postcode, so a unit in Galston and a large house are priced differently. The figure is fixed before any work starts. Every general treatment carries a 6-month warranty.
We cover it on scheduled runs, so a day's notice gets you the best slot. Galston is about 28.8 km north-west of the CBD in the Upper North Shore, and we give you a firm arrival time rather than an all-day window.
Properties on a bush edge get re-supplied continuously. That is why our work in Galston 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.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across Galston 2159, and we provide the written report agents and strata managers ask for.
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.
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.
An hour to two hours covers most jobs. The size of the building and the extent of the problem are what change it.
Every general treatment carries a 6-month warranty. Ring us if activity picks up again inside that period and we will arrange the return.
All of them. Galston sits alongside Middle Dural, Arcadia, Dural and Kenthurst in our coverage, and they are serviced on the same schedule.
