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 Bilgola Plateau sits, who covers it and what it costs.
Bilgola Plateau sits about 26.9 km north of the CBD in the Northern Beaches, and postcode 2107 is one we are in most weeks. We cover Bilgola Plateau on scheduled runs through the Northern Beaches, and we will give you a firm time rather than a window.
If you are near Village Plaza, Avalon Golf Course or Bilgola Plateau Park, that is ground we cover constantly - it is the busiest part of Bilgola Plateau for us.
We work under the Northern Beaches area here, and Clareville, Bilgola Beach and Newport are all on the same route, which matters when ant problems are moving between adjoining properties. Salt air and sandy ground keep sub-floors damp here, and damp is what sustains a population.
The ant calls we take from Bilgola Plateau are mostly ground-floor units with a damp sub-floor, and houses where the garage sits below the living level. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Our Bilgola Plateau runs also take in Angophora Reserve and the area near Clareville Beach, so the whole postcode is served.
Bookings for 2107 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Clareville and Bilgola Beach often share the same run, which is how earlier slots come up.
What looks like a queue is a chemical road. Each worker reinforces it on the way back, so the trail gets stronger the better the food is - and re-forms along the same skirting the moment the cleaning dries.
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.
Ants will defend aphids and scale from predators because that honeydew is their sugar supply. Deal with the scale on the plants near the house and the ant pressure drops with it.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

A small black ant with a glossy body, and the one most often in Sydney kitchens. It nests in wall cavities, the roof void and garden edges, trails along skirtings and cabling, and feeds readily on sweet bait.

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.

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.

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.

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.

An Elite job photo: gel placed directly on an active trail. Leave it be - the ants feeding there are the ones delivering it to the colony.
Where ants appear usually tells us where the nest is and which species we are dealing with.
When they come in from the outside wall, the nest is usually in the cavity or just outside in the garden. We work back from the entry point.
Loose fine soil along paving, driveway joints and the slab edge means coastal brown ants have nested underneath.
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.
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.
Lawns and garden beds are where bull ants and jumper ants nest. Their stings are painful and can trigger severe allergic reactions.

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.
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.
Before committing, we offer a little of each bait type and let the colony tell us which one it is on.
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.
Coastal brown ant nests under paving and along lawn edges get granular bait or direct treatment.
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 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) | Insects and sweet foods, taken mainly at night | A night inspection of the trails, bait near the nest, and moisture in timber repaired | Daytime-only treatment, which misses them entirely |
| 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 become active and start on brood, which shifts them onto protein | Early indoor trails, and sand piles returning to 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 reach full size and start stocking up ahead of the cold | Trails heading for the pantry and the pet food bowl |
| 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.
After sustained rain in Bilgola Plateau 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 column of ants going in and out of a weep hole means they are nesting in the cavity, not the garden. Treating the garden bed in that case does nothing at all for a Bilgola Plateau home.
If a trail runs up a shrub rather than into the house, the colony is farming aphids or scale for honeydew. Treating indoors will not stop it; the plant has to be dealt with too.
Finding the nest is the job - following the trail to it, not treating the visible end of it.
Baits are matched to the species and the season rather than used as a default.
Non-repellent products that foragers carry home, instead of sprays that scatter the colony.
A general ant treatment carries 6 months of cover - if they return inside it, so do we.

At roughly 26.9 km north of the city, Bilgola Plateau is on a route we run regularly. We cover it on scheduled runs, so a day's notice gets you the best slot. You will be given a time, not a window.
The air never really dries out near the water, so sub-floors and lower rooms hold moisture through the year. ants need that damp more than they need food, and here they always have it.
A mix of unit blocks and houses, most with a damp sub-floor or a ground level that sits low - and that is usually where we concentrate.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across Bilgola Plateau 2107, 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.
You do not normally need to leave. Anything requiring an empty room is short, and you will know about it before the work starts.
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. If it is not holding, call us - that is exactly what the warranty is for.
We cover the whole of Bilgola Plateau, from the streets around Angophora Reserve out to the suburb boundary and on into Clareville.
