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.

Blakehurst sits about 16.4 km south-west of the CBD in the St George & Bayside, and postcode 2221 is one we are in most weeks. We run Blakehurst on a regular route, and same-day attendance is usually available.
Around Blakehurst we work the pockets near Stuart Park, Bald Face Point Reserve and Beverley Park Golf Club most often, so the van is rarely far away when a job comes in.
Blakehurst is in the Georges River and Bayside area, and we cover Connells Point, South Hurstville and Kogarah Bay on the same runs - handy if you own more than one property or your ant problem has come from next door. Salt air and sandy ground keep sub-floors damp here, and damp is what sustains a population.
What we see in Blakehurst is ground-floor units with a damp sub-floor, and houses where the garage sits below the living level. Describing it accurately when you book saves a second visit.
Every part of 2221 is covered as standard.
Bookings for 2221 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Connells Point and South Hurstville often share the same run, which is how earlier slots come up.
The reason the trail returns to the same spot in a Blakehurst kitchen is that it is marked chemically. Wiping it buys hours. Treating the colony that maintains it is the only thing that ends it.
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.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Blakehurst kitchen is the difference between a result and a wasted visit.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

The small glossy black one you find in the kitchen. It runs along skirtings, window frames and cabling, nesting in wall cavities, roof voids and the edges of garden beds, and it takes sweet bait without much persuading.

Tiny and brown, with a distinct large-headed soldier. The sign is loose sand appearing between pavers, along the slab edge and in grout lines. Many nests to a colony, which is why we use oil-based granular baits.

A small, matt brown ant that moves quickly in heavy trails. Its nests have multiple queens and link up with others nearby, so the problem often spans several properties. Repellent spray is the worst thing to use on it.

Large ants that come out at night and nest in soil, hollow trees or damp timber. Unlike the overseas carpenter ants they seldom threaten structure - but a nest in a wall tells you there is moisture there.

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.

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.
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.
Mating flights produce the winged swarms you see in spring and summer. Finding them indoors suggests a mature colony inside rather than outside.
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.
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.
If the bait is not what they want today, they will walk past it. Preference moves between sugar and protein with brood demand, so we test and change as 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 work out which ant it is and follow the trails back, which is what locates nests in wall cavities, under paving, along garden edges and in roof spaces.
A test with small amounts of each bait type - sweet, protein, oil-based - tells us what the colony wants at this point in its cycle.
Indoor placements are gel on the trail - skirting, window frames, travel routes - sited away from children and pets.
We treat the foundation line, weep holes, door frames and paths with a non-repellent so incoming ants carry it with them.
Granular bait or direct treatment for coastal brown ant nests under pavers and in lawn edges.
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 | 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 | 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 | Sugar for the most part, with periodic protein demand | Slow baits and a non-repellent applied along the property line | Using a repellent barrier spray - it divides the multi-queen colony |
| 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 | 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 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) | 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) | 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.
A branch touching the roof is a bridge. Mulch banked against brickwork is harbourage. Most of what brings ants inside a Blakehurst home is in the garden immediately around it.
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 Blakehurst after a storm is almost always this.
Ants in the cavity of a Blakehurst house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
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.
We use non-repellents the foragers carry back, not sprays that split the colony up.
A general ant treatment carries 6 months of cover - if they return inside it, so do we.

At roughly 16.4 km south-west of the city, Blakehurst is on a route we run regularly. Same-day attendance is usually available. You will be given a time, not a window.
Sandy ground drains fast but the humidity stays, which means the conditions under a house here suit ants in winter nearly as well as in summer.
Coastal housing here is a mix, but the damp lower level is consistent across most of it.
Yes. Houses, townhouses, units, strata common property, rentals and commercial sites in Blakehurst 2221 are all part of what we do, and the paperwork is the kind agents accept.
Yes, applied correctly. Products are registered for this use, placed out of reach rather than across open surfaces, and you will know what to stay off and for how long.
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. A return visit inside that period does not cost you anything.
We do. Blakehurst and Connells Point, South Hurstville, Kogarah Bay and Hurstville Grove are all on the same route, which helps if you own more than one property in the area.
