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.

Local technicians, fixed prices and a written report for every job in Elderslie.
If you are in Elderslie or anywhere else in 2570, you are in our Macarthur patch, 50.3 km south-west of the CBD. We travel out to Elderslie on planned runs through the Macarthur, so booking a day ahead gets you the best slot.
A lot of our Elderslie jobs are in the streets around Camden Golf Club and Camden Village Court, and we are out near Spring Farm Shopping Centre regularly enough that the technician usually knows the access before they arrive.
We work under the Campbelltown and Camden area here, and Camden, Kirkham and Narellan are all on the same route, which matters when ant problems are moving between adjoining properties. Estate blocks are compact with narrow side passages, so access and the perimeter are where most of the work happens.
The ant calls we take from Elderslie are mostly newer homes on small blocks where next door has the same problem. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Our Elderslie runs also take in Kirkham Park and the area near Harrington Green, so the whole postcode is served.
Your appointment is confirmed the day before with a real arrival time. Because Camden and Kirkham are covered on the same round, 2570 often has an earlier slot available.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Elderslie kitchen is the difference between a result and a wasted visit.
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.
The reason the trail returns to the same spot in a Elderslie kitchen is that it is marked chemically. Wiping it buys hours. Treating the colony that maintains it is the only thing that ends it.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

Small and shiny black. It is the usual kitchen ant here, trailing along skirting boards, window frames and power cables from nests in wall voids, roof spaces and the garden edge, and it takes sweet bait easily.

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.

Photo from an Elite job: gel bait placed along an active trail. The ants are left to feed and carry the bait home, so we ask customers not to wipe or spray the trail afterwards.
Where ants appear usually tells us where the nest is and which species we are dealing with.
A trail in from the outside wall means the colony is in the cavity or the garden edge - the entry point is what we follow.
Loose fine soil along paving, driveway joints and the slab edge means coastal brown ants have nested underneath.
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.
Swarms of winged ants in spring and summer are mating flights. Seen indoors, they can mean a mature colony inside the building.
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.
Bull ants and jumper ants nest in the lawn and garden beds. The sting is genuinely painful and in some people causes 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.
Ants can detect a supermarket spray and will simply route around it. A professional non-repellent is undetectable, so they walk through it and carry the active home to the colony.
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.
Identification comes first. Then we trace the trails to the entry points and the nests themselves, whether those are in walls, paving, garden edges or the roof.
We put out small quantities of sweet, protein and oil-based bait to see which the colony is actually taking today.
Indoor placements are gel on the trail - skirting, window frames, travel routes - sited away from 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.
Under-paver and lawn-edge nests are handled with granular bait, or treated directly where that is better.
A written summary, clear advice on what not to spray afterwards, 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 | 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 oily foods | Oil-based granular bait over paving and lawn margins | Attacking a single visible nest while the rest of the colony's nests carry on |
| 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) | 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) | 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) | 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) | Quiet outside, but colonies in warm wall cavities keep working | Ants around the heater, the hot water unit and the kitchen |
Most failed ant treatments come down to what happens in the week after.
Heavy rain floods shallow nests, and the colony moves to the nearest dry cavity - which is usually a wall, a subfloor or under a slab. A sudden indoor trail in Elderslie after a storm is almost always this.
Our Elderslie runs take in Camden Village Court and continue across to the Camden boundary - all the same service area.
Food premises need bait placement that will not contaminate, and records of what was used where. That is a different job from a domestic callout.
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.
Non-repellent products only - they are taken back to the nest rather than scattering it.
Six months of warranty on a general ant treatment, and a return visit if they come back inside it.

Get a Free QuoteAnt treatment starts from $89. The fixed price depends on the size of the property and how far the problem has spread, and we confirm it before we start - there is no call-out fee in Elderslie 2570. Every general treatment carries a 6-month warranty.
We cover it on scheduled runs, so a day's notice gets you the best slot. Elderslie is about 50.3 km south-west of the CBD in the Macarthur, and we give you a firm arrival time rather than an all-day window.
Estates are built fast and close. Shared fence lines, narrow side access and uniform construction mean ants rarely stay at just one address.
Recent estate housing - slab on ground, narrow side passages, young landscaping. The perimeter does most of the work.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across Elderslie 2570, and we provide the written report agents and strata managers ask for.
Yes, with the usual care. Everything is APVMA-registered and used to label, and we will work around pets, aquariums and anyone in the house with a respiratory condition if you tell us when you book.
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.
Allow one to two hours for a typical Elderslie 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.
All of them. Elderslie sits alongside Camden, Kirkham, Narellan and Narellan Vale in our coverage, and they are serviced on the same schedule.
