You may see cockroaches out in daylight, moving slowly or dying on the floor. This is the bait and growth regulator starting to work. Sweep them up and keep going.

Cockroach Control Across Wahroonga
Local technicians, fixed prices and a written report for every job in Wahroonga.
Postcode 2076 covers Wahroonga and the streets immediately around it. At about 19 km north-west of the CBD it falls in the Upper North Shore, where we have vans out daily. We run Wahroonga on a regular route, and same-day attendance is usually available.
Most weeks we are somewhere between Collingridge Reserve and Palmerstone Centre in Wahroonga, and Thornleigh Driving Range is close enough to be on the same run.
Wahroonga is in the Ku-ring-gai and Hornsby area, and we cover Warrawee, Hornsby and Turramurra on the same runs - handy if you own more than one property or your cockroach problem has come from next door. With bushland close by there is constant pressure from outside, so the perimeter and the fence line get as much attention as the house.
Most Wahroonga bookings come in as houses backing onto a reserve, where the pressure is constant from outside. Say which one applies when you call 1300 313 373 and the technician will have the right products on the van.
Our Wahroonga runs also take in Wahroonga station and the area near Anulla Place Park, so the whole postcode is served.
Bookings for 2076 are confirmed the day before with a set arrival time, not an all-day window. Jobs at Warrawee and Hornsby often share the same run, which is how earlier slots come up.

OVERVIEW
Cockroach Control That Breaks the Breeding Cycle
A cockroach can last weeks on almost nothing to eat but only days without water. That is why perfectly clean Wahroonga kitchens still get them: a dripping tap, a sweating pipe or a damp dishwasher seal is enough.
If your Wahroonga neighbour has cockroaches, you have a supply line. The treatment still works, but it needs the entry points sealed and ideally the adjoining property done at the same time.
Floor wastes, overflow pipes and the gap where a waste pipe passes through a cupboard base are all cockroach routes. A dry floor waste in a Wahroonga laundry is an open door, and a cup of water down it once a week closes it.
- Species identified before any product goes down
- Gel bait and growth regulator for German cockroaches
- Drains, subfloor and roof void for large species
- From $89 with a 6-month warranty
SYDNEY SPECIES
The Cockroaches We Deal With Most in Wahroonga
Knowing the species tells us where the nest is and which treatment will work. Two of these photos are from our own Sydney jobs.
German Cockroach
Light brown with two dark stripes behind the head, roughly 12 to 15 mm long. It lives indoors near warmth, food and moisture, and it is the species that breeds fastest inside a kitchen.
American Cockroach
Reddish-brown and as long as 4 cm. It belongs to the drainage system - sewers, stormwater pits, grease traps, the subfloor - and arrives in the kitchen overnight from there.
Australian Cockroach
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.
Brown-Banded Cockroach
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.
What We Find on Inspection
One of our Sydney inspections, showing German cockroach activity. The harbourage itself tells the story: droppings, cast skins and egg cases give us both the species and the scale.
Inside Kitchen Equipment

IDENTIFY THE PROBLEM
Which Cockroach Have You Got?
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 |
| Small ones in a bedroom or living room - behind a picture, inside the TV cabinet - not near water | Brown-banded cockroach | Furniture and electrical gear that stays warm and dry | Baiting aimed at the living and sleeping rooms rather than the kitchen |
| 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 |

WHY IT MATTERS
Why Cockroach Sprays Often Fail in Wahroonga
01
The Egg Case Is Protected
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.
02
Numbers Build Fast
A female will make several egg cases, and in kitchen warmth her young are breeding within weeks. Small numbers do not stay small.
03
Repellent Sprays Scatter Them
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.
04
Allergens Stay Behind
The allergen load - droppings, saliva, cast skins - is a recognised trigger for asthma and allergies, which is why clearing an infestation properly matters beyond the nuisance.
OUR PROCESS
How We Get Rid of Cockroaches in Wahroonga
What the technician does on the day, in the order it happens.
01
Identify & Map
First we establish which cockroach it is, then map where it lives - torch and mirror into hinges, motor cavities, behind kickboards and into wall voids. Everything after this depends on that map.
02
Clean-Out Advice
Where build-up is feeding them, you will get a short list of what to clean and the order to do it in - bait has to out-compete everything else available.
03
Gel Bait Placement
Professional gel goes down as small dots inside the cracks they already use. A cockroach feeds, goes home, and the product moves through the rest of the colony from there.
04
Growth Regulator & Voids
A growth regulator prevents the young reaching breeding age, while dust treats the wall voids and cavities that gel placement cannot get into.
05
Drains, Subfloor & Roof
Pits, floor wastes, the subfloor and the roof void get treated for the American and Australian species - they come in from there, so that is where it has to be done.
06
Warranty Check-In
A written summary comes with the job. Heavy activity still there after two weeks, or a return within 6 months of a general treatment, and we come back for nothing.
DIY VS PROFESSIONAL
Supermarket Products vs a Professional Program
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 | Quick on a cockroach you can actually reach | No effect on egg cases or harbourage, and it pushes the others deeper into cavities |
| 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 | Has a place when you have only seen one or two | Very little bait in each, and any crumbs or grease will out-compete it |
| Professional gel bait rotation | Carried home and shared where they shelter; if they start refusing one gel we rotate to another | Requires a clean kitchen and patience - days to a couple of weeks, not overnight |
| Insect growth regulator | Keeps nymphs from becoming breeding adults, so the egg-case cycle stops | It acts gradually, which is why it is always paired with a bait |
BEFORE WE ARRIVE
Kitchen Preparation for Cockroach Treatment in Wahroonga
Ten minutes of preparation lets the bait reach more cockroaches.
- Empty the under-sink cupboard and the vanity units in the bathrooms
- Stow food, crockery and cutlery behind closed cupboard doors
- Wipe grease from the stovetop, rangehood and around the bin
- Empty the bins - rubbish and recycling - the night before the treatment
- Keep the kickboards under the dishwasher and fridge clear so we can get to them
- Do not spray insecticide in the days before we come
- Pour water down the floor wastes and laundry tubs you hardly ever use
- Cover fish tanks and move pet food bowls off the floor
- Tell us if anyone else in the building is seeing cockroaches too
- Have the phone on you so we can call with the arrival time
AFTER TREATMENT
The Two Weeks After Treatment in Wahroonga
Days 4 to 14
Numbers should drop away through this period. Do not wipe the bait out of hinges and cracks, and do not spray over it - cockroaches will stop taking bait that has been sprayed.
- Wipe benches and sweep floors so there are no crumbs
- Store dry food in sealed containers from now on
- Fix the drips: taps, and any leaking waste pipe
If you rent or live in a unit
If it keeps going, let the agent or building manager know - cockroaches move between units readily. There is more on co-ordinated work on our apartment pest control page.
When to call us back
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.
LOCAL KNOW-HOW
Cockroaches in Sydney Kitchens and Apartment Blocks
For a Wahroonga cafe or restaurant the standard is different: a documented program, a site plan with numbered monitoring points, and a report an auditor will accept. We work to that rather than turning up with a spray pack.
We are around Collingridge Reserve and the streets behind it most weeks, and we cover every address in 2076, not just the main roads.
Humidity is the driver. In the Upper North Shore the summer months bring the fastest breeding, and the mild winters mean a population indoors never really slows - it just gets quieter.
WHY CHOOSE US
The Elite Pest Difference in Wahroonga
Species-First Treatment
Treatment follows identification. Indoor German cockroaches need bait and a growth regulator; drain-dwelling species need the pits and subfloor treated.
Kitchen-Friendly Methods
Precise gel placement into cracks and hinges rather than spraying the surfaces you cook on.
Units & Food Businesses
Single units through to commercial kitchens, with food premises worked outside trading hours.
6-Month Warranty
General treatments carry 6 months: a return within that window brings us back at no cost.
FAQ
Cockroach Control Questions, Answered
Everything you need to know before you book. Still unsure? Call us — we're happy to help.
Get a Free QuoteHow much does cockroach control cost in Wahroonga?
A cockroach treatment starts from $89. Two things move it: how big the place is, and how far it has already spread. We work that out on the phone or on site and tell you the figure before anything starts in Wahroonga. Every general treatment carries a 6-month warranty.
How quickly can you get to Wahroonga?
Same-day attendance is usually available. Wahroonga sits roughly 19 km north-west of the CBD, inside our Upper North Shore run, so we book a time and keep to it.
Why do cockroaches keep coming back in Wahroonga?
Properties on a bush edge get re-supplied continuously. That is why our work in Wahroonga is as much about the fence line and the perimeter as the inside of the house.
What sort of properties do you treat in Wahroonga?
Free-standing homes with gardens running into bush. We treat the boundary as seriously as the building.
Can you do a rental or a strata property in Wahroonga?
We do. A lot of our Wahroonga work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
Is the treatment safe around children and pets?
Yes. Everything we use is registered for the purpose and applied at label rates, and we place product where people and animals do not go. Tell us about pets, aquariums or anyone with a respiratory condition at booking.
Do I need to leave the property during treatment?
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.
How long does the treatment take?
Usually between one and two hours on site. Bigger properties and heavier infestations take more, and that is included in the quote rather than added afterwards.
What if the cockroaches come back?
Every general treatment carries a 6-month warranty. So if they turn up again within the warranty, ring us and we will attend.
Do you cover the suburbs around Wahroonga too?
Yes - we work right across the Ku-ring-gai and Hornsby area, which takes in Wahroonga and the suburbs around it.
