Budding splits the colony
Species with many queens, such as Argentine ants and several house ants, respond to a repellent spray by relocating. A few hundred workers and a queen move to a new spot, and you now have two colonies instead of one.

What we cover in Cheltenham, and how quickly we can get there.
If you are in Cheltenham or anywhere else in 2119, you are in our Ryde & the Northern District patch, 17.5 km north-west of the CBD. We run Cheltenham on a regular route, and same-day attendance is usually available.
A lot of our Cheltenham jobs are in the streets around Beecroft station and Booth Park, and we are out near Epping Oval regularly enough that the technician usually knows the access before they arrive.
Beecroft, Pennant Hills and Epping are all on the same route as Cheltenham. Most of the housing here shares a wall, a roof void or a sub-floor with something else, so we check what adjoins the property rather than treating it in isolation.
The bulk of our Cheltenham work is terraces and semis where the problem has come through a shared wall. Mention the detail when you call 1300 313 373 - it decides how long we need on site.
We also work the streets near Pennant Hills Marketplace and across toward Thornleigh Marketplace - the whole of 2119 is covered.
We confirm your slot the day before and arrive at a stated time. Beecroft and Pennant Hills sit on the same run, so earlier appointments in 2119 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.
Some ants want protein, some want sugar, and the wrong bait gets ignored completely. Identifying what is trailing through a Cheltenham kitchen is the difference between a result and a wasted visit.
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 Cheltenham 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.

A small black ant with a glossy body, and the one most often in Sydney kitchens. It nests in wall cavities, the roof void and garden edges, trails along skirtings and cabling, and feeds readily on sweet bait.

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.

Fast-moving, small and dull brown, in thick trails. Its nests are multi-queen and interconnected with neighbouring nests, so it spreads across properties - and repellent sprays accelerate exactly that.

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.

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.

An Elite job photo: gel placed directly on an active trail. Leave it be - the ants feeding there are the ones delivering it to the 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.
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.
When trails appear around the shower, vanity or toilet, moisture is the reason - often a slow leak the colony is drinking from.
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.

Species with many queens, such as Argentine ants and several house ants, respond to a repellent spray by relocating. A few hundred workers and a queen move to a new spot, and you now have two colonies instead of one.
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.
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.
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.
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.
We treat the foundation line, weep holes, door frames and paths with a non-repellent so incoming ants carry it with them.
Coastal brown ant nests under paving and along lawn edges get granular bait or direct treatment.
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 | 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 | 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 | Mainly sugars, protein at some points in the cycle | Slow-acting bait with a non-repellent treatment right across the boundary | Spraying a repellent barrier, which causes a multi-queen nest to bud |
| 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.
For a Cheltenham cafe or kitchen, ants are a compliance finding. We run a documented program with monitoring points and reports your auditor will accept rather than a one-off spray.
Anywhere in 2119, or over toward Beecroft, is inside the area we treat at the same price.
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 Cheltenham after a storm is almost always this.
We follow the trail back to the colony rather than treating the spot where you noticed it.
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.

Get a Free QuoteAnt treatment starts from $89. There is no call-out charge in Cheltenham 2119. The final number comes down to the property itself, and it is fixed before we begin. Every general treatment carries a 6-month warranty.
Same-day attendance is usually available. Our Ryde & the Northern District technicians cover Cheltenham daily, and you get a confirmed arrival time when you book.
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.
Mostly terrace and semi. We look at the party wall, the sub-floor and the roof space, because those are the routes between houses.
Yes - freestanding homes, townhouses, apartments, rentals and business premises in Cheltenham 2119 are all covered, with documentation suitable for an agent or a strata manager.
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.
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. So if they turn up again within the warranty, ring us and we will attend.
We do. Cheltenham and Beecroft, Pennant Hills, Epping and North Epping are all on the same route, which helps if you own more than one property in the area.
