Budding splits the colony
Multi-queen species - Argentine ants and several house ants among them - react to a repellent by splitting. A queen and a few hundred workers relocate, and one colony becomes two.

LOCAL COVERAGE
Ant Control in Mortlake
What we cover in Mortlake, and how quickly we can get there.
Mortlake is part of the Inner West, 10 km or so west of the GPO, and 2137 is a postcode we know well. We run Mortlake on a regular route, and same-day attendance is usually available.
Our Mortlake work takes in the streets by Cabarita Shopping Centre and Concord Golf Club, through to Spyglass Park at the other end.
Mortlake is in the Inner West, Burwood, Strathfield and Canada Bay area, and we cover Breakfast Point, Cabarita and Concord West on the same runs - handy if you own more than one property or your ant problem has come from next door. Terraces, semis and converted blocks share cavities and risers, which is why a single-unit treatment often does not hold on its own.
What we see in Mortlake is terraces and semis where the problem has come through a shared wall. Describing it accurately when you book saves a second visit.
Uhrs Point Reserve and the remainder of 2137 are on the same run.
You get a confirmed time, not a window. We plan the 2137 run the day before, and if Breakfast Point or Cabarita is on the same round there is often an earlier slot going.

OVERVIEW
Ant Control That Reaches the Nest in Mortlake
A colony's preference also shifts with the season. Spring brood-rearing wants protein; later in summer the same Mortlake colony wants sugars.
After heavy rain the opposite happens - flooded nests push colonies up and inside. Both extremes send ants into Mortlake houses for different reasons.
Some species excavate soft, damp timber rather than eat it. Finding them in a Mortlake window frame or bathroom wall usually means moisture has been getting into that timber for a while.
- The species identified and the trail followed back to the nest
- Baits selected for what that colony is actually taking
- Non-repellent perimeter products, so the colony does not bud
- Starting at $89 and carrying 6 months of warranty
SYDNEY SPECIES
Common Ants in Sydney Homes in Mortlake
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.
Black House Ant
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.
Coastal Brown Ant
Small brown ants that include a bigger-headed soldier caste. Sandy soil pushed up between pavers and along slab edges gives them away. Colonies run to many nests, and oil-based granular bait is what works.
Argentine Ant
Dull brown, small, and noticeable for the thickness and speed of its trails. Multi-queen nests connect to neighbouring ones, which is how an infestation covers several properties. Repellents make it markedly worse.
Sugar or Carpenter Ants
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.
Nests in Mortar and Masonry
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.
Gel Bait on the Trail
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.
READING THE SIGNS
What Your Ant Problem Is Telling Us in Mortlake
Where ants appear usually tells us where the nest is and which species we are dealing with.
A Trail From the Window or Weep Hole
A trail in from the outside wall means the colony is in the cavity or the garden edge - the entry point is what we follow.
Sand Piles Between Pavers
Fine soil pushed up along paving, driveways and slab joints is the classic sign of coastal brown ants nesting underneath.
Ants in Power Points or Appliances
A nest in a power point or appliance is about warmth. Spraying into electrical fittings is dangerous - tell us and we will treat it the right way.
Winged Ants After Warm Rain
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.
Ants in the Bathroom
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.
Large Stinging Ants in the Yard
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.

WHY IT MATTERS
Why Household Sprays Make Ants Worse in Mortlake
Repellent vs non-repellent
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 must beat the food on offer
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.
Patience beats instant results
Give it days, not hours. Bait has to be carried through the colony, and spraying the trail afterwards destroys the couriers doing that work. Our blog covers budding in more detail.
OUR PROCESS
How We Treat an Ant Colony in Mortlake
Tracing first, then baits and non-repellent products that do the work after we leave.
01
Species & Trail Tracing
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.
02
Bait Preference Test
Sweet, protein and oil-based baits are offered in small amounts so the colony shows us its current preference.
03
Indoor Baiting
Gel bait goes along trails, window frames and skirting where ants travel, out of reach of children and pets.
04
Non-Repellent Perimeter
We treat the foundation line, weep holes, door frames and paths with a non-repellent so incoming ants carry it with them.
05
Nest & Paving Treatment
Granular bait, or direct nest treatment, for the coastal brown ant nests under paving and at lawn edges.
06
Written Advice & Warranty
You get a summary, advice on what not to spray, and a 6-month warranty on the general treatment.
BAIT SELECTION
Matching the Treatment to the Ant Species in Mortlake
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 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, active after dark | Night trail inspection, baiting near the nest, and dealing with damp timber | Inspecting in daylight when the colony is not foraging |
| Bull ants and jumper ants | Nectar and insects, outdoors | Treating the nest directly where it sits in lawn or garden bed | Digging the nest out by hand, which is how people get stung |
SYDNEY SEASONS
When Ants Are Busiest Around Sydney in Mortlake
| 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) | 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) | The colony is at its largest and laying in stores before winter | Trails running into pantries and to pet food |
| 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 |
BEFORE AND AFTER
Dos and Don'ts for Ant Treatment in Mortlake
Most failed ant treatments come down to what happens in the week after.
- Do leave the trail alone before we arrive so we can follow it
- Do seal away the sugar, honey, fruit and pet food
- Do deal with leaks and damp close to where the ants are appearing
- Do trim back vegetation that touches the building
- Don't spray shop-bought insecticide onto trails or bait placements
- Don't mop the skirting or wipe the window sills for roughly a week
- Don't pressure-wash the treated perimeter or paving for a few weeks
- Don't apply anything into power points, light switches or appliances
- Mention pets, ponds and vegetable gardens near the building
- Call us if activity has not dropped after two weeks
LOCAL KNOW-HOW
Ants in Sydney Gardens, Paving and Units in Mortlake
If a trail runs up a shrub rather than into the house, the colony is farming aphids or scale for honeydew. Treating indoors will not stop it; the plant has to be dealt with too.
Ants in the cavity of a Mortlake house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
A branch touching the roof is a bridge. Mulch banked against brickwork is harbourage. Most of what brings ants inside a Mortlake home is in the garden immediately around it.

FAQ
Ant Control Questions, Answered
Everything you need to know before you book. Still unsure? Call us — we're happy to help.
Get a Free QuoteWhat am I looking at for ant control in Mortlake?
Ant treatment starts from $89. There is no call-out charge in Mortlake 2137. The final number comes down to the property itself, and it is fixed before we begin. Every general treatment carries a 6-month warranty.
How soon can someone come out to Mortlake?
Same-day attendance is usually available. We are about 10 km west of the city here, and Mortlake is covered by the Inner West team.
Why are ants such a problem in Mortlake?
Most of this area is terrace, semi and converted block, and those share more than people realise - cavities, roof spaces, drainage. ants use all of it.
What kind of buildings do you work on around Mortlake?
Older joined housing. The treatment takes account of shared walls, continuous sub-floors and roof voids that run between properties.
Do you treat units and rentals in Mortlake?
Yes. We work in houses, units, strata blocks, rentals and commercial premises across Mortlake 2137, and we provide the written report agents and strata managers ask for.
Do we need to worry about pets or children afterwards?
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.
Can we stay home while the treatment is done?
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.
How much time should I allow?
For a standard Mortlake home, one to two hours. We would rather tell you it will take longer up front than rush it.
Is there a warranty if they return?
Every general treatment carries a 6-month warranty. Ring us if activity picks up again inside that period and we will arrange the return.
Which areas around Mortlake do you cover?
Yes. As well as Mortlake we cover Breakfast Point, Cabarita, Concord West and Concord on the same runs, so a job that crosses a boundary can be handled in one visit.
