Licensed pest technician applying a perimeter treatment to the outside of a brick home — Most of what you pay for is the part you never see: the diagnosis, the product choice and the record of what went where.

The short version: 2026 Perth ranges by job

These are the typical ranges we quote across Perth's northern suburbs. They're GST inclusive, and every one of them gets itemised in writing before anything is booked. If a number you've been quoted is a long way outside these, keep reading, because the reason is usually one of the six things further down.

Job	Typical 2026 Perth range	What it normally includes
General pest treatment (3-bed home)	$250 – $350	Cockroaches, spiders, silverfish and ants, inside and out. Six-month re-treatment period.
External ant treatment	$250 – $400	Colony-level treatment with non-repellents and baits. Three-month re-treatment period.
German cockroach kitchen program	$250 – $450	Gel bait plus growth regulator, follow-up visit built in.
Rodent program, first visit	$220 – $380	Species ID, entry-point audit, tamper-resistant stations, a written sealing plan.
Spider treatment (stand-alone)	$220 – $300	External web-and-harbourage treatment, internal only where needed.
Vacate flea treatment	$150 – $220	By floor area, certificate to you and your agent within the hour.
Wasp nest removal	$180 – $280	Accessible paper wasp nest treated and removed, roofline checked.

The full list, including commercial per-visit rates and bed bugs, lives on our investment guide. It's updated when our rates change, which is not often.

Why the range is a range and not a number

Nobody can quote pest work accurately without knowing four things, and any operator who gives you a single figure over the phone without asking is either guessing or planning to "find something" on the day. Here's what actually moves the figure.

1. The size and shape of the property

A villa on a 300 square metre block and a two-storey home on a quarter-acre with a shed, a pergola and 60 metres of fence line are not the same job, even if the pest is. Product volume, time on site and the number of harbourages all scale with the property. This is the single biggest driver of the general pest range.

2. Which pest, and which species

"Ants" is not a diagnosis. Black house ants on a windowsill are a ten-minute add-on to a general treatment. A coastal brown ant super-colony running under your paving, the lawn and two neighbours' yards is a dedicated job with slow-acting non-repellents, and it can need a second visit. Same with cockroaches: an Australian cockroach wandering in from the garden is covered by the general treatment; German cockroaches breeding behind the dishwasher need a gel-and-growth-regulator program with a follow-up. The species decides the chemistry, and the chemistry decides the figure.

3. How established the problem is

A rat that moved into the roof last week is a two-station job with some proofing. A colony that's been up there since last winter, with insulation shredded and droppings through the ceiling space, is more stations, more time and a bigger sealing plan. The same logic applies to termites: early activity in one pergola post is a different conversation from live workings through the roof framing.

4. The construction

This one matters most for termites. Installing a chemical management system means creating a continuous treated zone around the building. Where there's garden bed, we trench. Where there's paving or a concrete path, we drill, inject and reseal every 200 to 300 millimetres. A home with paving right around it takes longer and uses more product than one with beds on three sides. Perimeter length and how much of it is hard surface explain almost the whole $2,500 to $5,500 spread.

What you're actually paying for

People assume the money goes on chemical. It mostly doesn't. On a typical general pest job the product is a small fraction of the figure. What you're paying for is a licensed technician's hour or two on site, the diagnosis before anything is applied, the correct product chosen for the pest and the site, the application to its APVMA label, and the paperwork afterwards. That last part sounds boring until you need it: in WA, a registered pest management business has to keep a record of every treatment for three years under the Health (Pesticides) Regulations 2011, listing the product, the active, the rate, the areas and the technician's licence number. You should get a copy without asking. If you don't, ask why.

Price is what you pay. Value is what you receive. On a pest job, the value is a correct diagnosis and a record you can rely on. The spray is the easy bit.

Six questions that expose a bad quote

Use these on us as well. A fair operator answers all six without blinking.

Is it itemised? One number hides what you're paying for. You want the treatment, the report and any follow-up as separate lines so you can accept some or all.
What's the re-treatment period, and is it written down? A promise with no scope means nothing. A real one has a defined scope and a timeframe: six months for general pest, three for ants and rodents, 30 days for fleas and wasps, in our case. Ours is on the re-treatment promise page with its conditions.
Is there a call-out fee or a deposit? There shouldn't be. Coming to look and quote should be free, and nothing should be paid before the work is done.
Can the figure change on the day? Watch for a "variations" clause. Sometimes something concealed genuinely turns up, but the right response is to stop, show you and re-quote before continuing, never to add it to the invoice afterwards.
What product, and at what rate? You don't need the chemistry degree, but the technician should be able to name the active and confirm it's being applied to label. Vagueness here is a bad sign.
Who's turning up? Ask whether the person quoting is the person treating, and whether they hold a WA pest management technician's licence. The licence number goes on your treatment record.

Invoices and a calculator laid out on a desk — An itemised quote is the whole test. If you can't see what each line is for, you can't compare it with anything.

Why one quote is so much cheaper than another

Usually one of four things. The scope is smaller (external only, no roof void, no sub-floor). The chemistry is cheaper (a repellent spray that knocks down the foragers you can see instead of a colony treatment that reaches the nest, which is why the ants come back in three weeks). There's no report and no follow-up. Or there's a variation clause that lifts the figure once the technician is on site. Ask the six questions and the gap normally explains itself. A low figure that needs a second visit at full rate isn't low.

Our view, for what it's worth: quarterly servicing is overkill for most Perth homes. An annual general treatment with a top-up after heavy rain is the right cadence under normal pressure, and we'll tell you that on the day if that's what your house needs. Selling you four visits a year when one will do is a way to make a quote look small and an annual figure look big.

DIY or professional: the honest split

Some jobs are genuinely DIY. A few black house ants at a windowsill, a paper wasp nest the size of a golf ball you can reach from the ground at dusk, sticky traps to work out where the cockroaches are coming from. Have a go.

Some jobs are not, and the supermarket product makes them worse. Repellent sprays on a coastal brown super-colony split the colony into more nests. Bug bombs push German cockroaches into wall voids to breed. And termites: hardware-store termite spray on an active infestation in a Perth home is $40 of regret. Termite management in WA is licensed work for a reason, and the product that actually works is not sold retail.

Rule of thumb: if it's a single pest you can see, in one spot, and it's not a termite, try once. If it's back within a fortnight, the problem is the colony or the harbourage, not the strength of your spray, and that's the point to ring someone.

How to get a fixed figure from us

Send the address and what you're seeing, by text, email or the form. For most jobs we quote from the address using the floor plan and property details, itemised, within the hour, so the figure is fixed before we arrive. For termites we inspect first and quote the system the house actually needs, with a drawing of where it goes. No call-out fee, no deposit, seven-day terms, and the treatment record follows every job by email.

Frequently asked

How much does pest control cost in Perth?

A general pest treatment for a standard three-bedroom home is typically $250 to $350 including GST. Targeted ant, cockroach or rodent programs run $220 to $450 depending on how established the problem is. Termite work is quoted by the perimeter and construction: $250 to $350 for an inspection, $2,500 to $5,500 for a full chemical management system.

How much does an exterminator charge per visit?

We don't use the word exterminator, because no treatment removes every pest for good. A single general pest visit is $250 to $350. Follow-up visits, where a program needs them, are $90 to $140. There's no call-out fee for a look and a quote.

How much does termite treatment cost?

A chemical management system installed to AS 3660.2:2017 typically runs $2,500 to $5,500 in Perth, depending on the length of the perimeter and how much of it is paved or concreted. A baiting system is $1,500 to $3,000 to install plus an ongoing monitoring program. An inspection first tells you which one the house needs.

Is it cheaper to bundle treatments?

Yes. Adding a general pest treatment to a vacate flea treatment, or a spider treatment to a rodent program, on the same visit brings the combined figure down because the travel and set-up are shared. Ask for the bundle to be itemised so you can see the saving.

Do you charge more for the far northern suburbs?

No travel line on any quote. For Alkimos, Butler and Yanchep we group bookings by day so the drive is absorbed in scheduling rather than charged to you.

What's included in the general pest treatment?

An internal treatment for cockroaches, spiders, silverfish and ants using non-staining, low-odour products and a growth regulator, an external perimeter and harbourage treatment, and a treatment record with a prevention plan. Six-month re-treatment period on the pests listed on your invoice.

Why is a rodent job dearer than I expected?

Because the bait is the cheap part. The value is finding how they're getting in and giving you a sealing plan, otherwise you're feeding a revolving door. Two tamper-resistant stations, the entry-point audit and the plan are what the first-visit figure covers.
