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.

Where Berowra Waters sits, who covers it and what it costs.
Berowra Waters is part of the Upper North Shore, 30.7 km or so north of the GPO, and 2082 is a postcode we know well. We cover Berowra Waters on scheduled runs through the Upper North Shore, and we will give you a firm time rather than a window.
A lot of our Berowra Waters jobs are in the streets around Wideview Road Reserve and Berowra Marketplace, and we are out near Berowra Village Shopping Centre regularly enough that the technician usually knows the access before they arrive.
This is the Ku-ring-gai and Hornsby area, and our runs here also take in Berowra Heights, Berrilee and Berowra. Backing onto bush means re-entry is the issue, so proofing and the perimeter do the real work here.
The ant calls we take from Berowra Waters are mostly houses backing onto a reserve, where the pressure is constant from outside. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Every part of 2082 is covered as standard.
Bookings for 2082 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Berowra Heights and Berrilee often share the same run, which is how earlier slots come up.
Many ants get most of their sugar from honeydew - the secretion of aphids and scale insects they actively protect on garden plants. A Berowra Waters garden with a scale problem is feeding the ant colony that then comes indoors.
After heavy rain the opposite happens - flooded nests push colonies up and inside. Both extremes send ants into Berowra Waters houses for different reasons.
Ants lay a pheromone trail that other workers follow, which is why the line is so precise and why it reappears in exactly the same place after you wipe it. Cleaning a Berowra Waters kitchen removes the smell for a few hours, not the colony that laid it.
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.

Very small brown ants, with soldiers that have noticeably bigger heads. You spot them by the fine sandy soil pushed up through paving joints, slab edges and grout. The colonies are big and multi-nested, so oil-based granular bait is the tool.

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, often active at night, that nest in soil, hollow trees and softened or damp timber. Unlike the notorious overseas species they are rarely a structural pest, but a nest in a wall often points to a leak worth fixing.

An Elite job photo showing a nest in masonry. Weep holes and cracked mortar lead into the wall cavity - the spot black house ants most often choose.

From an Elite job - gel bait set down on a live trail. The ants feed and carry it back to the nest, which is why we ask you not to wipe or spray that trail afterwards.
Where ants appear usually tells us where the nest is and which species we are dealing with.
When they come in from the outside wall, the nest is usually in the cavity or just outside in the garden. We work back from the entry point.
Loose fine soil along paving, driveway joints and the slab edge means coastal brown ants have nested underneath.
They go into switches and appliances for the warmth. Keep insecticide out of power points and tell us, so it can be treated safely.
Those spring and summer swarms of winged ants are mating flights. If they are coming out inside the house, there may be a mature colony in the building.
Ant trails at the shower, vanity or toilet usually come down to moisture - either damp in the wall or a slow leak they are drinking from.
Lawns and garden beds are where bull ants and jumper ants nest. Their stings are painful and can trigger severe allergic reactions.

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.
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.
Small amounts of sweet, protein and oil-based bait show what the colony is feeding on right now.
Gel bait goes along trails, window frames and skirting where ants travel, out of reach of children and pets.
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.
The job ends with a written summary, advice on what to avoid spraying, and a 6-month warranty.
The same bait does not suit every ant. This is how we choose.
| Species | Usually feeding on | Treatment approach | Common mistake |
|---|---|---|---|
| Black house ant | Honeydew and sugary liquids, switching to protein when there is brood | Sweet gel on active trails and a non-repellent perimeter at frames and weep holes | Washing the trail down each day, which only relocates the foraging 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 | 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) | Nocturnal, on sweet foods and insects | Trails inspected at night, bait placed near the nest, timber moisture fixed | Only ever treating during the day, when there is nothing to see |
| 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) | 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) | Foraging peaks, and warm humid spells trigger mating flights | Swarms of winged ants, and heavy trails following storms or heatwaves |
| Autumn (Mar to May) | Colonies peak in size and stock up for the cooler months | Trails into the pantry and around pet bowls |
| 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 single trail across a Berowra Waters prep bench during an inspection is enough to cause a problem. The program is built to prevent that rather than react to it.
After sustained rain in Berowra Waters we get a run of calls, and the cause is consistent: shallow nests waterlogged, the colony moved into a wall cavity or subfloor to dry out.
Brick cavities are dry, warm and undisturbed, which makes them ideal nesting. The weep hole is the doorway and it is usually where we start on a Berowra Waters job.
Trails are traced to the colony, not just sprayed where you saw them.
Which bait we use depends on the ant and the season: sweet, protein or oil-based.
Non-repellent products only - they are taken back to the nest rather than scattering it.
General ant treatments are covered. If ants come back within 6 months, so do we.

We cover it on scheduled runs, so a day's notice gets you the best slot. Berowra Waters sits roughly 30.7 km north of the CBD, inside our Upper North Shore run, so we book a time and keep to it.
Leaf litter, fallen timber and undisturbed ground right up to the boundary keep ants populations healthy next door to you, whatever you do indoors.
Detached houses on larger blocks with bush on a boundary, so the fence line and perimeter matter as much as the interior.
We do. A lot of our Berowra Waters work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
Yes. The products are registered for this use and applied at label rates, and placement keeps them away from where children and animals go. Let us know at booking about pets, fish tanks or anyone with asthma and we will plan the visit around it.
Usually not. Most ant control work is done with you there, and anything that needs the room vacated is for a short period we will tell you about beforehand.
An hour to two hours covers most jobs. The size of the building and the extent of the problem are what change it.
Every general treatment carries a 6-month warranty. Call us if activity picks up again and we will arrange the return visit.
Yes - we work right across the Ku-ring-gai and Hornsby area, which takes in Berowra Waters and the suburbs around it.
