Seeing more of them at first is expected. They come out, move slowly and die - the bait and growth regulator doing their job. Sweep up and leave everything else alone.

Where Guildford West sits, who covers it and what it costs.
We treat cockroaches right across 2161. Guildford West is roughly 22.8 km west of the city, which puts it well inside the Greater Parramatta & Cumberland run our technicians work. We run Guildford West on a regular route, and same-day attendance is usually available.
A lot of our Guildford West jobs are in the streets around Yennora station and O S Young Park, and we are out near Hyland Road Reserve regularly enough that the technician usually knows the access before they arrive.
This is the City of Parramatta and Cumberland area, and our runs here also take in Yennora, Merrylands West and Fairfield. Terraces, semis and converted blocks share cavities and risers, which is why a single-unit treatment often does not hold on its own.
Most Guildford West bookings come in as terraces and semis where the problem has come through a shared wall. Say which one applies when you call 1300 313 373 and the technician will have the right products on the van.
The rest of 2161 is covered too, including the pockets around Neeta City Shopping Centre and Woodville Golf Course.
The 2161 run is set the day before and you are given an arrival time. Where Yennora and Merrylands West fall on the same round, we can usually bring the visit forward.
The usual route into a Guildford West home is carried, not crawled. Appliance deliveries, recycled cartons and second-hand white goods are the three we trace most often.
Almost none of the colony is out where you can see it. They are packed into the warm humid gaps - the kickboard void, the dishwasher housing, under the fridge motor, inside a cupboard hinge - so a Guildford West job that treats surfaces has missed the point.
They do not bite. What they do is walk through a drain and then over the surface you cut food on, which is a contamination problem - and the reason we treat the pipework and the harbourage, not just the floor.
Knowing the species tells us where the nest is and which treatment will work. Two of these photos are from our own Sydney jobs.

At 12 to 15 mm and light brown with two dark stripes behind the head, this is the species we find living permanently indoors. Warmth, food and moisture are all it needs, and it reproduces faster than any other cockroach here.

Up to roughly 4 cm long and reddish-brown. You find it in sewers, pits, grease traps and under the floor, and it travels up through drains after dark rather than nesting indoors.

About the same size as the American, distinguished by pale yellow margins behind the head and along the wing edges. It is an outdoor cockroach - mulch, garden beds and subfloors - that wanders inside.

A small banded cockroach that favours warmth and dryness rather than moisture. Look for it high up: behind frames, inside electrical enclosures and in cupboards well away from the sink.

An Elite job photo of German cockroach activity on a Sydney inspection. Egg cases, shed skins and droppings in the harbourage are how we work out what we are dealing with.

From an Elite commercial job: harbourage found inside kitchen equipment. The motor housing, the door seal and the hollow leg hold warmth after close and almost never get cleaned out.
Where and when you see them is often a better clue than size. Use this to tell us what you are seeing when you call.
| What you see | Likely species | Where the nest usually is | What treatment focuses on |
|---|---|---|---|
| Cockroaches barely 15 mm out in the open by day, with dark pepper-like specks where cupboards meet | German cockroach, and an established one | Inside hinges, appliance cavities, the kickboard void, the housings of the appliances themselves | Gel baits rotated through the job, a growth regulator, and crack-and-crevice application indoors |
| A single big one after dark by the laundry tub, the bathroom or a floor drain | American cockroach | Stormwater and sewer pits, the space under the floor, floor wastes that have dried out | Treating the pits and drains, the subfloor, and sealing the gaps where pipes pass through |
| Big cockroaches with pale yellow margins, usually in the garage or arriving from outside | Australian cockroach | Garden mulch, leaf litter, stacked firewood and the roof cavity | Perimeter treatment outside, dusting the roof void, and dealing with garden harbourage |
| Little cockroaches well away from the kitchen: bedrooms, the TV unit, behind wall hangings | Brown-banded cockroach | Warm dry spots in furniture and inside appliances | Bait placed where they actually are, in the living and sleeping areas |
| A unit where the problem never quite ends, weeks after a DIY attempt | German cockroach spreading from a neighbouring lot | Shared risers and bin rooms, plus the cavities inside shared walls | A building-wide, coordinated treatment. See strata pest control |

The egg case - around 30 eggs, carried by the female until just before hatching - is shielded from anything applied to a surface. That is why the population reappears after a DIY attempt.
Each female can produce several egg cases in her life, and the young mature in weeks in a warm kitchen. A few cockroaches become an infestation quickly.
A repellent product scatters rather than clears - deeper into the wall void, through to the unit next door - and leaves residue where food is prepared.
Cockroach droppings, saliva and cast skins are recognised triggers for allergies and asthma, so a lingering infestation is a health issue as well as a nuisance.
What the technician does on the day, in the order it happens.
We confirm the species and use a torch and inspection mirror to find harbourage: hinges, appliance housings, kickboards and wall voids. The treatment follows what we find, not a standard routine.
We identify the build-up that is feeding them and tell you what to deal with first. The less competing food there is, the harder the bait works.
We place gel in precise dots along their travel routes rather than spraying. They feed, return to the harbourage, and the effect spreads through the population by contact and feeding.
A growth regulator prevents the young reaching breeding age, while dust treats the wall voids and cavities that gel placement cannot get into.
The outdoor species need outdoor treatment - stormwater pits, floor wastes, under the floor and the roof cavity, which is where they actually live before they reach your kitchen.
You receive a written summary of what was found and done. Heavy activity after two weeks, or a return within the 6-month general-treatment warranty, brings us back free of charge.
Some DIY options help with a few stray cockroaches. An established German cockroach colony is a different job.
| Method | What it does well | Where it falls short |
|---|---|---|
| Aerosol surface spray | Deals with the individual in front of you | Never touches the egg cases or the voids, and drives the rest further into the walls |
| Bug bombs and foggers | Puts product across everything out in the open | Does not get into harbourage, coats your benchtops, and can split the colony up |
| Retail bait stations | Worth using when numbers are genuinely low | There is very little bait in them, and crumbs or grease will beat them every time |
| Professional gel bait rotation | Fed on inside the harbourage and shared through the colony, with the option to swap formulations | Only works with the food competition removed, and needs days to two weeks |
| Insect growth regulator | Prevents the young reaching breeding age, which ends the egg-case cycle | Slow by design, so we never use it on its own - it goes in with bait |
Ten minutes of preparation lets the bait reach more cockroaches.
Seeing more of them at first is expected. They come out, move slowly and die - the bait and growth regulator doing their job. Sweep up and leave everything else alone.
You should see a steady decline. Leave the gel where we put it in hinges and cracks, and keep your own insecticide away from it, or they will refuse to feed.
Keep the agent or building manager informed if it does not settle; cockroaches travel between flats. Our apartment pest control page covers the options for a whole block.
If you still see steady activity after two weeks, or cockroaches return within 6 months of a general treatment, call 1300 313 373 for a warranty re-treatment.
Humidity is the driver. In the Greater Parramatta & Cumberland the summer months bring the fastest breeding, and the mild winters mean a population indoors never really slows - it just gets quieter.
Cockroaches do not respect a lease boundary. In a Guildford West block they move through service risers, shared drains and the cavity between units, so treating one kitchen in a building with a problem is money spent on a holding pattern.
We are around Hyland Road Reserve and the streets behind it most weeks, and we cover every address in 2161, not just the main roads.
What we use depends on what you have: baits and growth regulators for German cockroaches, pit and subfloor treatment for the drain species.
Bait placed in cracks and hinges, not a blanket spray over food preparation surfaces.
Single units through to commercial kitchens, with food premises worked outside trading hours.
General treatments carry 6 months: a return within that window brings us back at no cost.

Get a Free QuoteA cockroach treatment starts from $89. The fixed price depends on the size of the property and how far the problem has spread, and we confirm it before we start - there is no call-out fee in Guildford West 2161. Every general treatment carries a 6-month warranty.
At roughly 22.8 km west of the city, Guildford West is on a route we run regularly. Same-day attendance is usually available. You will be given a time, not a window.
Joined housing is the reason. Where walls, roof voids and sub-floors are continuous between properties, cockroaches are a street-level problem rather than a house-level one.
Joined housing with ageing drainage. That combination decides where product goes far more than the floor plan does.
Yes. Houses, townhouses, units, strata common property, rentals and commercial sites in Guildford West 2161 are all part of what we do, and the paperwork is the kind agents accept.
Yes, with the usual care. Everything is APVMA-registered and used to label, and we will work around pets, aquariums and anyone in the house with a respiratory condition if you tell us when you book.
In most cases you can stay. Where an area does need to be left clear it is for a couple of hours at most, and we say so before we start.
For a standard Guildford West home, one to two hours. We would rather tell you it will take longer up front than rush it.
Every general treatment carries a 6-month warranty. If activity continues past the expected period, call us and we will come back.
