If you’ve ever Googled “how to get rid of cockroaches” at 11pm, you’ve probably come across a lot of confident advice. The problem? Much of it is flat-out wrong, or at least wrong for Queensland.
Pest behaviour in South East Queensland is shaped by a climate and housing stock that’s genuinely different from the rest of Australia, let alone overseas. The humidity, the heat, the prevalence of timber high-set homes, the proximity to bush, these all change how pests behave and what actually works against them.
After 60 years of pest control in Brisbane and the Gold Coast, we’ve heard every myth going. Here are the ones that cost homeowners the most.
Myth 1: ‘If My Home Is Clean, I Won’t Get Pests’
This is probably the most persistent myth in pest control, and it’s genuinely damaging because it makes people feel embarrassed when they do have a problem, so they wait longer to get help.
Cleanliness reduces food sources for some pests, particularly cockroaches and rodents. But it does almost nothing to deter termites, spiders, mosquitoes, or silverfish. Termites don’t care how clean your home is, they care about timber, moisture and warmth. A meticulously maintained Queenslander with a leaky downpipe is far more attractive to termites than a slightly untidy home with no moisture issues.
In SEQ’s subtropical climate, pests are present in large numbers in the natural environment year-round. They don’t need your home to be dirty to want to come inside, they need it to be accessible, warm and humid. Which, for most of the year, it is.
The reality: Good hygiene helps. But it’s not a substitute for preventative pest management.
Myth 2: ‘DIY Spray From the Hardware Store Is Just as Good’
This one has some truth buried in it, which makes it more misleading, not less.
Over-the-counter sprays can knock down visible insects on contact. If you spray a cockroach and it dies, the product worked. What it didn’t do is address the colony, the harbourage points, the moisture source, or the entry pathway.
Licensed pest technicians in Queensland use APVMA-registered products that are not available to the general public. More importantly, they apply them using specific methods – targeted dusting, non-repellent baits, perimeter treatments – that are designed to disrupt the entire pest population rather than the individuals you can see. For social insects like cockroaches, ants and termites, killing the ones you see is largely irrelevant if the nest is untouched.
There’s also the issue of repellent vs non-repellent chemistry. Many consumer sprays are repellent, they drive pests away from treated areas rather than eliminating them. In a home, that often just means the infestation moves somewhere less visible.
The reality: DIY products have their place for minor, isolated issues. For anything with a harbourage, a nest, or a colony, professional treatment is categorically more effective.
Myth 3: ‘Termites Only Attack Old or Neglected Homes’
Termites do not discriminate by age or condition of a property. They discriminate by timber species, moisture content and accessibility.
A brand-new home with untreated structural timbers, a small gap in the slab edge, or a garden bed sitting against the brickwork is just as vulnerable as an older home, sometimes more so, because buyers and owners are less vigilant about a property they assume is ‘new and fine.’
In SEQ specifically, the subterranean termite species most common to the region – including Coptotermes acinaciformis and Schedorhinotermes species – are aggressive, widespread and capable of causing significant structural damage within 12 to 18 months of initial infestation. The warm, humid conditions that make this part of Queensland so liveable are the same conditions these species thrive in.
The reality: No home in SEQ is immune to termites. Annual termite inspections are not a luxury, they’re the baseline.
Myth 4: ‘I Had a Treatment Done, So I’m Covered Indefinitely’
Pest control treatments have a service life. It varies by pest, product type, application method and environmental conditions, but nothing lasts forever, and in Queensland’s climate, treatments tend to break down faster than in cooler, drier parts of the country.
A general pest spray typically provides effective coverage for six to twelve months under normal conditions. Termite barriers – chemical or physical – require regular inspection and, in the case of chemical barriers, periodic replenishment. The Australian Standard for termite management (AS 3660) specifies that properties with termite management systems should be inspected at least annually.
Homeowners who ‘had something done three years ago’ and haven’t thought about it since are often the ones with the most significant problems.
The reality: Pest control is ongoing maintenance, not a one-off fix. Ask your technician for a recommended service interval and put it in the calendar.
Myth 5: ‘Seeing One Cockroach Doesn’t Mean There’s an Infestation’
Yes and no. Seeing one cockroach outdoors, or one wandering in from outside on a warm evening, is probably not cause for alarm. Seeing a small cockroach inside your kitchen during the day is a different matter.
German cockroaches in particular – the small, fast species most commonly found in Queensland kitchens and bathrooms – are almost exclusively indoor insects. They don’t wander in from outside. If you’re seeing one during daylight hours, it’s typically a sign that the harbourage is overcrowded, which means the infestation is already well-established.
American cockroaches (the large ones) are more likely to be opportunistic indoor visitors, but they breed outdoors in large numbers in SEQ’s warm conditions and can establish indoors quickly if conditions are right.
The reality: One cockroach inside, during the day, in a kitchen or bathroom, warrants a proper investigation. Don’t wait until you’re seeing dozens.
Myth 6: ‘Ultrasonic Pest Repellers Work’
They don’t. This has been tested repeatedly, and the evidence is consistent: ultrasonic plug-in devices have no meaningful effect on common household pests. Australian consumer advocacy groups have raised concerns about products in this category for years, and there is no peer-reviewed research supporting their efficacy against cockroaches, rodents, spiders or termites.
This is worth stating plainly because these products are widely sold and actively marketed. People buy them, believe they’re protected, and skip professional inspections. That’s the real harm, not the cost of the device itself.
The reality: Save the power point for something useful.
Myth 7: ‘Spiders in the Home Protect Against Other Pests’
There’s a version of this that’s true, some spider species do prey on insects, including mosquitoes and flies. But using this as a reason to tolerate a significant spider presence in a Queensland home is poor reasoning.
SEQ is home to several medically significant spider species, including funnel-webs (particularly in the hinterland and bushland fringe areas), redbacks and white-tails. The benefit of a few less mosquitoes is not worth the risk of a child or pet encountering a redback in the garage.
Beyond safety, significant spider populations in a home are often a secondary indicator, they’re there because there are other insects for them to feed on. Addressing the underlying insect issue typically reduces the spider population as a consequence.
The reality: A spider here and there is normal. A notable spider presence usually means a broader pest issue worth investigating.
Myth 8: ‘Body Corporates Handle Pest Control in Strata Properties’
This is a genuine grey area that catches a lot of unit and townhouse owners off guard. Body corporate responsibility for pest control in Queensland is governed by body corporate legislation and the specific scheme’s by-laws, and the division of responsibility between common areas and individual lots is not always what owners expect.
Generally speaking, a body corporate is responsible for pest management in common areas: stairwells, gardens, external walls and shared spaces. Individual lot owners are typically responsible for pest management within their own lot. Where an infestation originates from a common area or structural element, the picture becomes more complicated.
Termite infestations in particular can create significant disputes in strata properties. If termites enter through the slab or external wall of a building, the question of who is responsible for treatment and structural repair is not always straightforward.
The reality: Don’t assume the body corporate has you covered. Know your by-laws, and if you’re purchasing a strata property, a pre-purchase pest inspection of your specific lot is still worthwhile regardless of any body corporate pest management programme.
Don’t Let Myths Cost You
Pest control misinformation isn’t just frustrating, it delays treatment, encourages ineffective DIY approaches, and in the case of termites, can mean tens of thousands of dollars in structural damage by the time the problem is properly identified.
