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 Beecroft sits, who covers it and what it costs.
Beecroft is part of the Ryde & the Northern District, 18.7 km or so north-west of the GPO, and 2119 is a postcode we know well. We run Beecroft on a regular route, and same-day attendance is usually available.
If you are near Thornleigh Marketplace, Beecroft station or Cheltenham station, that is ground we cover constantly - it is the busiest part of Beecroft for us.
Cheltenham, Pennant Hills and Epping are all on the same route as Beecroft. The building stock is close-packed, so we look at what the property adjoins before deciding where product goes.
Beecroft jobs tend to be older semis with a paved rear courtyard and a sub-floor that no longer dries out. Let us know which when you ring and we will plan the visit around it.
Our Beecroft runs also take in Booth Park and the area near Observatory Park, so the whole postcode is served.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Beecroft kitchen is the difference between a result and a wasted visit.
Where we find ants in a Beecroft 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.
People assume a trail means something was left out. Around Beecroft it is just as likely to be the bathroom, because water is the scarcer resource in summer.
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.

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, 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.

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.

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.
Loose fine soil along paving, driveway joints and the slab edge means coastal brown ants have nested underneath.
Ants nesting in switches and electrical fittings are drawn to the warmth. Do not spray into power points; tell us so we can treat 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.
Bathroom trails around the shower, basin or toilet normally mean water: damp in the wall cavity, or a slow leak supplying the colony.
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.

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.
Retail sprays repel: the ants know they are there and go round. Professional non-repellents do not register, so the foragers deliver the active to the colony for us.
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.
Bait takes days to work through a colony. If you spray the trail the day after we leave, you kill the couriers. 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.
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.
Gel bait goes along trails, window frames and skirting where ants travel, 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.
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, 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 | 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) | The colony restarts and begins brood production, raising its protein needs | First trails inside, and sandy soil showing up in paving joints |
| Late spring to summer (Nov to Feb) | Foraging at its height, and mating flights whenever it turns warm and humid | Winged ants indoors, and much heavier trails after storms and heatwaves |
| Autumn (Mar to May) | The colony is at its largest and laying in stores before winter | Trails running into pantries and to pet food |
| Winter (Jun to Aug) | Quiet outside, but colonies in warm wall cavities keep working | Ants around the heater, the hot water unit and the kitchen |
Most failed ant treatments come down to what happens in the week after.
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 Beecroft after a storm is almost always this.
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 Beecroft job.
The garden is usually the source. Shrubs touching the walls, mulch up against the footings and irrigated beds give a colony everything it needs within a metre of your kitchen.
Trails are traced to the colony, not just sprayed where you saw them.
The bait is chosen for the species and the time of year - sweet, protein or oil-based.
Non-repellent products only - they are taken back to the nest rather than scattering it.
If ants return within 6 months of a general treatment, we return at no charge.

Get a Free QuoteAnt treatment starts from $89. Two things move it: how big the place is, and how far it has already spread. We work that out on the phone or on site and tell you the figure before anything starts in Beecroft. Every general treatment carries a 6-month warranty.
Same-day attendance is usually available. Beecroft sits roughly 18.7 km north-west of the CBD, inside our Ryde & the Northern District run, so we book a time and keep to it.
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.
Older joined housing. The treatment takes account of shared walls, continuous sub-floors and roof voids that run between properties.
Yes. Houses, townhouses, units, strata common property, rentals and commercial sites in Beecroft 2119 are all part of what we do, and the paperwork is the kind agents accept.
It is, as long as you follow what we tell you on the day - usually keeping off treated surfaces for a couple of hours. Let us know at booking about young children, pets or an aquarium.
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.
Most ant control jobs in a Beecroft home take between one and two hours on site, depending on the size of the property and how much of it is affected.
Every general treatment carries a 6-month warranty. A return visit within the warranty period costs you nothing.
We do. Beecroft and Cheltenham, Pennant Hills, Epping and Westleigh are all on the same route, which helps if you own more than one property in the area.
