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 Leonay.
Postcode 2750 covers Leonay and the streets immediately around it. At about 53.3 km west of the CBD it falls in the Penrith & the Outer West, where we have vans out daily. We travel out to Leonay on planned runs through the Penrith & the Outer West, so booking a day ahead gets you the best slot.
The Leonay addresses we attend cluster around Lapstone station and Glenbrook station. Leonay Oval is another part of the suburb we are called to often.
Under Penrith City and Hawkesbury, we cover Leonay and Regentville, Emu Plains and Jamisontown alike. Bigger properties mean sheds, stables and stacked timber to check as well as the house.
The ant calls we take from Leonay are mostly rural-residential homes where it started in a stable or a feed store. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
The rest of 2750 is covered too, including the pockets around Childrens Park and Lennox Village Shopping Centre.
You get a confirmed time, not a window. We plan the 2750 run the day before, and if Regentville or Emu Plains is on the same round there is often an earlier slot going.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Leonay kitchen is the difference between a result and a wasted visit.
Pharaoh and some other small species nest indoors in warm voids and never go outside at all. In a Leonay house that changes the treatment completely - and makes spraying actively harmful, because it buds the colony.
A trail along a bench is foragers, and foragers are maybe five per cent of the colony. The queens, the brood and most of the workers are in a nest you have not found, which is why wiping the trail achieves nothing lasting in a Leonay kitchen.
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.

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.

Dull brown, small, and noticeable for the thickness and speed of its trails. Multi-queen nests connect to neighbouring ones, which is how an infestation covers several properties. Repellents make it markedly worse.

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.

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 coming in from the external wall normally means a nest in the cavity or at the garden edge, and that entry point is where the tracing begins.
Fine soil pushed up along paving, driveways and slab joints is the classic sign of coastal brown ants nesting underneath.
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.
Swarms of winged ants in spring and summer are mating flights. Seen indoors, they can mean a mature colony inside the building.
Trails in the bathroom point to water in the wall or a slow leak the ants have found.
Bull ants and jumper ants nest in lawns and garden beds. Their stings hurt and can cause serious allergic reactions in some people.
One call to a licensed Sydney technician gets you straight advice and a fixed quote within 30 minutes.
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.
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.
Sweet, protein and oil-based baits are offered in small amounts so the colony shows us its current preference.
Gel is placed on the trails themselves - along window frames and skirting boards - and positioned out of reach of children and pets.
A non-repellent treatment around the foundation, weep holes, door frames and paths intercepts ants coming in.
Coastal brown ant nests under paving and along lawn edges get granular bait or direct 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 | Sweet liquids and honeydew; protein while the colony is raising young | Gel bait placed on trails, non-repellent applied at weep holes and window frames | Wiping trails clean daily, so the colony simply forages on a different route |
| 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 | Sugars primarily, sometimes protein | Slow-acting baits combined with non-repellent treatment across the boundary | A repellent barrier, which splits nests that hold many queens |
| 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 | Outdoor feeders on insects and nectar | Direct treatment of the nest in the lawn or garden bed | Opening the nest up by hand and being stung for it |
| 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) | 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) | 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) | 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.
The Penrith & the Outer West 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.
Anywhere in 2750, or over toward Regentville, is inside the area we treat at the same price.
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.
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.
Nothing repellent, because that causes budding. Non-repellent products get carried home instead.
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. There is no call-out charge in Leonay 2750. The final number comes down to the property itself, and it is fixed before we begin. Every general treatment carries a 6-month warranty.
We cover it on scheduled runs, so a day's notice gets you the best slot. Leonay is about 53.3 km west of the CBD in the Penrith & the Outer West, and we give you a firm arrival time rather than an all-day window.
Larger properties have more places for ants to live undisturbed, and the house is simply the warmest option once the weather turns.
Large blocks where the shed, the feed store or the woodpile is as likely to be the problem as the house itself.
Yes - freestanding homes, townhouses, apartments, rentals and business premises in Leonay 2750 are all covered, with documentation suitable for an agent or a strata manager.
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.
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.
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. If it is not holding, call us - that is exactly what the warranty is for.
Yes - we work right across the Penrith City and Hawkesbury area, which takes in Leonay and the suburbs around it.
