Budding splits the colony
A repellent does not kill a multi-queen colony, it divides it. A queen and several hundred workers shift to a new site, leaving you with two nests instead of one.

Llandilo sits about 46.5 km north-west of the CBD in the Penrith & the Outer West, and postcode 2747 is one we are in most weeks. We travel out to Llandilo on planned runs through the Penrith & the Outer West, so booking a day ahead gets you the best slot.
Our Llandilo work takes in the streets by Jordan Springs Shopping Centre and Dunheved Golf Club, through to Wianamatta Nature Reserve at the other end.
Penrith City and Hawkesbury is the council area for Llandilo, and we treat Jordan Springs, Cranebrook and Berkshire Park on the same schedule. On larger blocks the outbuildings, sheds and woodpiles are usually where the problem is sitting, so they are part of the inspection.
What we see in Llandilo is acreage properties with outbuildings that need checking alongside the house. Describing it accurately when you book saves a second visit.
Wherever you are in 2747, you are inside the area our technicians cover.
Bookings for 2747 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Jordan Springs and Cranebrook often share the same run, which is how earlier slots come up.
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 Llandilo kitchen.
If trails appear in winter, or in a first-floor bathroom with no outdoor route, the nest is probably inside the building.
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.
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.

Small brown ants that include a bigger-headed soldier caste. Sandy soil pushed up between pavers and along slab edges gives them away. Colonies run to many nests, and oil-based granular bait is what works.

Small and flat brown in colour, running in dense fast trails. Because nests hold many queens and join with those next door, the infestation is usually bigger than one property. Never spray a repellent on it.

These are the large night-active ants that nest in soil, hollow trees and timber that has softened with damp. Structural damage is uncommon in Australia, but a wall nest points to a leak worth chasing.

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.
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.
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.
They go into switches and appliances for the warmth. Keep insecticide out of power points and tell us, so it can be treated safely.
Winged ants swarming in the warmer months are reproductives on a mating flight. Indoors, that can indicate an established colony within the structure.
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.

A repellent does not kill a multi-queen colony, it divides it. A queen and several hundred workers shift to a new site, leaving you with two nests instead of one.
Repellent means detectable, and detectable means avoided. Non-repellent products let foragers walk through and transfer the active to the rest of 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.
It takes days for bait to move through a colony. Spraying the trail the day after our visit kills the very ants delivering it - 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.
We put out small quantities of sweet, protein and oil-based bait to see which the colony is actually taking today.
Inside, gel bait follows the trails: window frames, skirting, the routes they already use, always placed where children and pets cannot get to it.
A non-repellent band around the footings, weep holes, door frames and paths catches ants as they come in.
Granular bait or direct treatment for coastal brown ant nests under pavers and in lawn edges.
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 | 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 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) | Sweet foods and insects, foraging after dark | Inspecting trails at night, baiting close to the nest, and fixing damp timber | Working only in daylight hours, when these ants are not out |
| Bull ants and jumper ants | Nectar and insects taken outdoors | Direct nest treatment wherever it is in the lawn or beds | Trying to dig it out yourself and getting stung |
| 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 peaks, and warm humid spells trigger mating flights | Swarms of winged ants, and heavy trails following storms or heatwaves |
| Autumn (Mar to May) | Full colony size, and foraging to build stores before it cools | Pantry trails, and ants on the pet food |
| Winter (Jun to Aug) | Outside activity drops away, though nests in warm wall cavities carry on | Ants near heaters, hot water units and in the kitchen |
Most failed ant treatments come down to what happens in the week after.
If your Llandilo paving keeps developing little sand volcanoes, sweeping them away is treating the spoil rather than the nest. The colony is in the bedding sand under the slab.
For a Llandilo cafe or kitchen, ants are a compliance finding. We run a documented program with monitoring points and reports your auditor will accept rather than a one-off spray.
We are around Wianamatta Nature Reserve most weeks and cover every street in 2747, including the ones off the main roads.
Finding the nest is the job - following the trail to it, not treating the visible end of it.
The bait is chosen for the species and the time of year - sweet, protein or oil-based.
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.

We cover it on scheduled runs, so a day's notice gets you the best slot. Llandilo sits roughly 46.5 km north-west of the CBD, inside our Penrith & the Outer West run, so we book a time and keep to it.
Acreage means more harbourage. Stacked timber, disused sheds and open ground all support ants populations that eventually work their way inward.
Bigger properties with sheds and open ground, where the source is usually outside the house.
Yes - freestanding homes, townhouses, apartments, rentals and business premises in Llandilo 2747 are all covered, with documentation suitable for an agent or a strata manager.
Yes, when it is applied properly. We use registered products at label rates and tell you which areas to keep clear and for how long. Mention pets, fish tanks or allergies when you book.
Usually not. Most of the work is done with you in the house, and where a room does need to be clear it is for a short period we will tell you about on arrival.
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. That is the point of the warranty - you do not pay twice for the same problem.
We do. Llandilo and Jordan Springs, Cranebrook, Berkshire Park and Werrington Downs are all on the same route, which helps if you own more than one property in the area.
