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.

Our Hills District technicians cover North Kellyville and the rest of 2155 as a matter of course - it is only about 31.3 km north-west of the city. We cover North Kellyville on scheduled runs through the Hills District, and we will give you a firm time rather than a window.
A good share of our North Kellyville work is in the streets around Lansdowne Road Reserve and The North Village.
Beaumont Hills, Kellyville and Rouse Hill are all on the same route as North Kellyville. 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 North Kellyville are mostly properties where the fence line matters as much as the kitchen. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
The whole of 2155 is on our regular run.
The 2155 run is set the day before and you are given an arrival time. Where Beaumont Hills and Kellyville fall on the same round, we can usually bring the visit forward.
In a dry spell ants move indoors looking for moisture, which is why a spotless North Kellyville kitchen still gets trails in January. The sink, the pet bowl and the shower recess are the attractions.
A colony's preference also shifts with the season. Spring brood-rearing wants protein; later in summer the same North Kellyville colony wants sugars.
Ant control is colony control. Everything else - sprays, powders, wiping the bench - is managing symptoms, and around North Kellyville that is why the same trail comes back every spring.
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.

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.

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.

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 photo of gel bait on an active trail. The whole point is letting them feed and take it home, so the trail must be left alone once we have treated 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.
Fine sand pushed up through paving, driveway and slab joints is coastal brown ants underneath, almost without exception.
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.
Trails around the shower, vanity or toilet often mean moisture in the wall or a colony drinking from a slow leak.
Bull ants and jumper ants nest in the lawn and garden beds. The sting is genuinely painful and in some people causes 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.
Supermarket sprays are repellent: ants detect them and walk around them. Professional non-repellent products are not detected, so foragers walk through, pick up the active and carry it back to nest mates.
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.
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.
Tracing first, then baits and non-repellent products that do the work after we leave.
First the species, then the trails - followed back to where they enter and to nests in the wall, under paving, at garden edges or in the roof space.
Sweet, protein and oil-based baits are offered in small amounts so the colony shows us its current preference.
Inside, gel bait follows the trails: window frames, skirting, the routes they already use, always placed where children and pets cannot get to it.
A non-repellent treatment around the foundation, weep holes, door frames and paths intercepts ants coming in.
Coastal brown ant nests under paving and along lawn edges get granular bait or direct treatment.
Written summary, instructions on what not to spray, and a 6-month warranty covering 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 | 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 primarily, sometimes protein | Slow-acting baits combined with non-repellent treatment across the boundary | A repellent barrier, which splits nests that hold many queens |
| 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 | Nectar and insects taken outdoors | Direct nest treatment wherever it is in the lawn or beds | Trying to dig it out yourself and getting stung |
| 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 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) | Colonies peak in size and stock up for the cooler months | Trails into the pantry and around pet bowls |
| 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 North Kellyville after a storm is almost always this.
Ants in the cavity of a North Kellyville house will appear at power points, architraves and ceiling roses - anywhere the cavity opens into the room.
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.
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.
Six months of warranty on a general ant treatment, and a return visit if they come back inside it.

Undisturbed ground, leaf litter and fallen timber right to the boundary mean ants are always established next to the house. Re-entry, not eradication, is what we are managing here.
Homes with sub-floors and roof voids backing onto reserve - we inspect all three plus the boundary.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across North Kellyville 2155, and we provide the written report agents and strata managers ask for.
Yes, when it is applied properly. We use registered products at label rates and tell you which areas to keep clear and for how long. Mention pets, fish tanks or allergies when you book.
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.
