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.

What we cover in Waterloo, and how quickly we can get there.
We treat ants right across 2017. Waterloo is roughly 3.5 km south of the city, which puts it well inside the Inner South & City Fringe run our technicians work. Our technicians are through Waterloo most days, so same-day attendance is usually available.
If you are near Park Sydney Village, The Australian Golf Club or Green Square station, that is ground we cover constantly - it is the busiest part of Waterloo for us.
This is the City of Sydney and Bayside area, and our runs here also take in Redfern, Zetland and Beaconsfield. The building stock is close-packed, so we look at what the property adjoins before deciding where product goes.
Around Waterloo the pattern is fairly consistent: terraces and semis where the problem has come through a shared wall. Tell us which it is on the phone and we will come prepared for it.
Kensington Reserve and Jack Floyd Reserve are on the same round, which means every part of 2017 is within our area.
We confirm your slot the day before and arrive at a stated time. Redfern and Zetland sit on the same run, so earlier appointments in 2017 come up regularly.
What you are looking at is a supply line, not a population. Treat the line and the colony sends another one tomorrow along a slightly different route.
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.
In a dry spell ants move indoors looking for moisture, which is why a spotless Waterloo kitchen still gets trails in January. The sink, the pet bowl and the shower recess are the attractions.
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.

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.

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.

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.

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.

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.
Loose fine soil along paving, driveway joints and the slab edge means coastal brown ants have nested underneath.
Electrical fittings and switches stay warm, which is why ants nest in them. Do not spray into them; let us know and we will handle it properly.
Swarming winged ants in spring or summer are a mating flight. Seen inside the house, it often means the colony is mature and in 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 the lawn and garden beds. The sting is genuinely painful and in some people causes a serious allergic reaction.

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.
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.
Ants will ignore bait that does not suit their current needs. Because they alternate between sugar and protein depending on the brood, we test preference rather than assume.
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.
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.
We run gel along the active trails, window frames and skirting, keeping every placement out of reach of children and animals.
A non-repellent treatment around the foundation, weep holes, door frames and paths intercepts ants coming in.
Under-paver and lawn-edge nests are handled with granular bait, or treated directly where that is better.
You get a summary, advice on what not to spray, 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 | 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 | 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 | 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) | Sweet foods and insects, mostly at night | Night-time trail inspection, bait near the nest, fix moisture in timber | Treating only in daylight when the ants are not active |
| 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) | 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) | Little happening outdoors, but a nest in a heated wall stays active | Activity around heaters, the hot water unit and kitchen areas |
Most failed ant treatments come down to what happens in the week after.
Ants in the cavity of a Waterloo house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
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.
Honeydew is a sugar supply the colony will defend. We point out the plant on a Waterloo job because otherwise the trail simply re-establishes.
We follow the trail back to the colony rather than treating the spot where you noticed it.
The bait is chosen for the species and the time of year - sweet, protein or oil-based.
Non-repellent products that foragers carry home, instead of sprays that scatter the colony.
Six months of warranty on a general ant treatment, and a return visit if they come back inside it.

At roughly 3.5 km south of the city, Waterloo is on a route we run regularly. Same-day attendance is usually available. You will be given a time, not a window.
These houses were built joined together, and they have aged that way. Party walls, continuous roof voids and shared drainage give ants a route your front door has no bearing on.
Terraces and semis that share walls, roof voids and drainage - so we look at what the property adjoins before deciding where product goes.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across Waterloo 2017, 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.
Most of the time you can carry on as normal. If a particular area needs to be empty we will flag it when we arrive and it is rarely more than a couple of hours.
Allow an hour to two hours for most properties. A bigger building, or one where the problem has spread, takes longer - and we would rather tell you that when quoting than rush it.
Every general treatment carries a 6-month warranty. Call us if activity picks up again and we will arrange the return visit.
All of them. Waterloo sits alongside Redfern, Zetland, Beaconsfield and Moore Park in our coverage, and they are serviced on the same schedule.
