Budding splits the colony
Where a species has many queens, a repellent spray causes budding rather than death. Part of the colony, queen included, moves elsewhere, and you have doubled the problem.

Where Lethbridge Park sits, who covers it and what it costs.
We treat ants right across 2770. Lethbridge Park is roughly 40.4 km west of the city, which puts it well inside the Blacktown & Mount Druitt run our technicians work. We travel out to Lethbridge Park on planned runs through the Blacktown & Mount Druitt, so booking a day ahead gets you the best slot.
If you are near Emerton Village, Tandarra Park or Yiraaldiya National Park, that is ground we cover constantly - it is the busiest part of Lethbridge Park for us.
The suburb sits in the Blacktown City area. Blackett, Ropes Crossing and Shalvey are all covered on the same day, so a problem that has spread across a boundary can be handled in one visit. 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 Lethbridge Park are mostly estate houses with narrow side access and a shared fence line. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Wherever you are in 2770, you are inside the area our technicians cover.
When you book, we confirm the 2770 run the day before and give you an arrival time rather than a window. If we are already out at Blackett or Ropes Crossing that morning, we will usually offer you the earlier slot.
Where we find ants in a Lethbridge Park wall or frame, we look for the water first. Fix the leak and the timber dries; leave it and another colony will use the same cavity.
Indoor nests sit in wall cavities, behind splashbacks, under baths and in roof insulation. Finding them is most of the work on a Lethbridge Park job.
Several of the species we treat around Lethbridge Park 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.
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.

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.

Photo from an Elite job: an ant nest emerging from a mortar joint. Weep holes and cracked mortar lead straight into the wall cavity, which is where many black house ant colonies live.

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.
Ants arriving from the outside wall usually nest in the cavity or garden edge. The entry point is where we start tracing.
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.
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 and jumper ants live in lawn and garden-bed nests. The sting hurts, and for some people it brings on a serious allergic reaction.

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.
Bait is only taken if it matches what the colony wants right now. Their preference moves between sugar and protein as the brood changes, so we test and switch baits accordingly.
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.
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.
Gel is placed on the trails themselves - along window frames and skirting boards - and positioned out of reach of children and pets.
The perimeter gets a non-repellent product - foundation, weep holes, door frames, paths - which intercepts ants before they are inside.
Under-paver and lawn-edge nests are handled with granular bait, or treated directly where that is better.
You receive the job summary in writing, guidance on what to leave alone, and 6 months of 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 | Oils and protein rather than sugars | Granular bait with an oil base, spread on paving and at the lawn edge | Boiling water down one hole - there are dozens of other nests |
| 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, 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 | 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) | Activity resumes and brood rearing starts, so the colony wants protein | Trails appearing indoors again, and fresh sand piles in the 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) | Full colony size, and foraging to build stores before it cools | Pantry trails, and ants on the pet food |
| Winter (Jun to Aug) | Outdoor foraging slows right down while nests in heated walls continue | Ants showing up by heaters, hot water services and in kitchens |
Most failed ant treatments come down to what happens in the week after.
Our Lethbridge Park runs take in Emerton Village and continue across to the Blackett boundary - all the same service area.
Nests under paving are sheltered, warm and almost impossible to flood out. They need bait placed at the active entrances, not a hose.
Honeydew is a sugar supply the colony will defend. We point out the plant on a Lethbridge Park job because otherwise the trail simply re-establishes.
The trail gets traced to its source. Spraying where you saw ants achieves very little.
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.
General treatments come with 6 months. Ants back within that window means we come back too.
