Days 1 to 3
The first few days usually look worse: cockroaches in the open, slow, or dead on the floor. It means the treatment has started. Just sweep them away.

Local technicians, fixed prices and a written report for every job in Strathfield.
Strathfield is part of the Inner West, 12.4 km or so west of the GPO, and 2135 is a postcode we know well. We run Strathfield on a regular route, and same-day attendance is usually available.
Around Strathfield we work the pockets near Freshwater Park, Frog Conservation Area and Strathfield Plaza most often, so the van is rarely far away when a job comes in.
We work under the Inner West, Burwood, Strathfield and Canada Bay area here, and Enfield, Burwood and Homebush are all on the same route, which matters when cockroach problems are moving between adjoining properties. The building stock is close-packed, so we look at what the property adjoins before deciding where product goes.
The bulk of our Strathfield work is apartments and converted blocks where the kitchen backs onto a service riser. Mention the detail when you call 1300 313 373 - it decides how long we need on site.
The whole of 2135 is on our regular run.
We confirm your slot the day before and arrive at a stated time. Enfield and Burwood sit on the same run, so earlier appointments in 2135 come up regularly.
Think of it as two populations: the adults you see, and the eggs you do not. Clear the first in a Strathfield kitchen and the second hatches on schedule about ten weeks later, which is why one-off treatments never hold.
Worth knowing before you blame yourself: this species is almost always introduced. Flatten cardboard rather than storing it, and check any used appliance before it comes inside.
If cockroaches keep appearing in a Strathfield bathroom rather than the kitchen, the drain is the first thing we check. They travel the pipework between units and come up wherever the seal has dried out.
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.

The largest one we deal with, around 4 cm and reddish-brown. Pits, sewers, grease traps and subfloors are where it breeds; the kitchen is somewhere it passes through at night.

Similar in size to the American cockroach but with pale yellow edges near the head and along the wings. Despite the name it is an outdoor species that comes in from gardens, mulch and subfloors.

Small and marked with pale bands. It is the one that does not want water, so it settles high and dry - behind pictures, inside electrical housings, in the top cupboards.

From one of our own inspections: German cockroach harbourage in a Sydney kitchen. The droppings, shed skins and egg cases are what we read to judge the species and the size of the population.

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 |
|---|---|---|---|
| A dozen small cockroaches on the bench in broad daylight, with dark specks in the cupboard corners | German cockroach, already a heavy infestation | The hinge of a cupboard door, behind the dishwasher and fridge, the kickboard void, inside appliances | Bait rotation and a growth regulator, applied into cracks and crevices right through the kitchen |
| 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 |
| An apartment where they come back a few weeks after you treated it yourself | German cockroach travelling between lots | The service risers, the bin room and the wall cavities the units share | Treating the building as one job. See strata pest control |

One call to a licensed Sydney technician gets you honest advice and a fixed quote within 30 minutes.
A German cockroach egg case holds around 30 eggs, and the female carries it until shortly before hatching. Killing adults on the surface leaves the next generation untouched.
One female produces several egg cases, and in a warm kitchen the young reach maturity within weeks. That is how a handful becomes a serious problem in a short time.
Bombs and supermarket sprays push cockroaches deeper into wall voids and into the unit next door, and can contaminate the surfaces you prepare food on.
Cast skins, droppings and saliva are recognised asthma and allergy triggers, which makes a long-running infestation a health issue rather than just an annoyance.
What the technician does on the day, in the order it happens.
Species confirmation comes first, then the search. Torch and inspection mirror into cupboard hinges, appliance housings, the kickboard void and the wall cavity, so the treatment is aimed rather than general.
If grease or food residue is sustaining the population, we point out exactly what to clean and in what order. Bait competes with whatever else is available, so this step changes the result.
Small dots of professional gel bait go into the cracks cockroaches travel through. They eat, return to harbourage and the effect passes through the population.
Two products with different jobs: the growth regulator stops nymphs maturing, and dust carries the treatment into voids and cavities beyond the reach of gel.
American and Australian cockroaches are treated at source: pits, floor wastes, subfloor and roof void. Treating the kitchen alone just handles the ones that already made it in.
Everything is recorded in writing. Still seeing heavy activity after a fortnight, or it returns inside the 6-month warranty on a general treatment? We return at no cost.
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 | Works on a cockroach you can actually see | Egg cases and harbourage are untouched, and it repels the others further in |
| 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 | A sensible first try on a light problem | Bait volume is too low for a colony, and competing food beats it |
| Professional gel bait rotation | Fed on where they shelter and passed between them, with formulations rotated as needed | Only works once competing food is gone, and takes days to a couple of weeks |
| Insect growth regulator | Stops the next generation maturing, breaking the cycle of egg cases | Deliberately slow, so bait does the knockdown alongside it |
Ten minutes of preparation lets the bait reach more cockroaches.
The first few days usually look worse: cockroaches in the open, slow, or dead on the floor. It means the treatment has started. Just sweep them away.
Expect activity to taper off. The bait dots in hinges and cracks need to stay put, and nothing should be sprayed over them - that is what makes cockroaches avoid bait.
Still seeing them? Tell the agent or building manager, since the source is often a neighbouring lot. Apartment pest control explains what a building-wide job involves.
Two weeks on and still seeing them regularly, or back inside 6 months of a general treatment? That is a warranty call - 1300 313 373.
A cockroach sighting in a Strathfield food business is a compliance problem before it is a pest problem. The program we run is built so the paperwork exists before anyone asks for it.
We are around Frog Conservation Area and the streets behind it most weeks, and we cover every address in 2135, not just the main roads.
Humidity is the driver. In the Inner West the summer months bring the fastest breeding, and the mild winters mean a population indoors never really slows - it just gets quieter.
What we use depends on what you have: baits and growth regulators for German cockroaches, pit and subfloor treatment for the drain species.
Gel goes into the cracks and hinges. Nothing gets sprayed across the bench you prepare food on.
One flat or a whole commercial kitchen - food premises are done outside trading hours.
A general treatment is covered for 6 months. Cockroaches inside that period mean a free return visit.

At roughly 12.4 km west of the city, Strathfield is on a route we run regularly. Same-day attendance is usually available. You will be given a time, not a window.
Terraces and semis share walls, roof voids and sub-floors, so cockroaches move between houses without ever going outside. That is the single biggest factor here.
Mostly terrace and semi. We look at the party wall, the sub-floor and the roof space, because those are the routes between houses.
