Roaches aren’t just annoying, unsightly intruders.

Their ability to spread parasites, fungi, bacteria, and viruses also poses a serious threat to the health of you and your family.

They can even trigger itchy eyes, dermatitis, and respiratory issues, making living spaces unpleasant and dangerous.

Signs of a Cockroach Infestation

Most of the time, Gold Coast home and business owners realise they have a cockroach infestation when they turn on the light at night and see dozens of cockroaches scurrying for cover.

Some of the other signs of a cockroach infestation include:

  • Cockroach droppings, which are typically tiny black pellets (often found near the nest site)
  • Ootheca (egg sacs), ovoid brown sacs about half the size of a cockroach that are attached to surfaces (these contain multiple cockroach eggs)
  • A musky or oily odour that intensifies as more cockroaches join the infestation
  • Damaged objects such as cardboard boxes, leather goods, books, and clothes
  • Shed skins, which can often look like dead albino roaches
  • Dark smear marks or stains on walls and surfaces

The presence of any of the above generally means you have an indoor cockroach infestation.  Because they’re normally symptomatic of a large, long-lived cockroach community, we strongly recommend hiring a professional pest technician to remove them. 

Spraying suspected nest areas with DIY insecticides will simply drive the cockroaches into hiding – they can survive for up to seven hours underwater and over a month without food, so exterminating them properly requires non-repellent baits and dusts.

Why Are Cockroaches So Bad?

Unlike termites, which threaten human structures, or ants, which are annoying and occasionally painful, cockroaches are direct threats to human health.

Like flies and rats, cockroaches are carriers for dozens of different diseases and parasites.  They normally acquire germs from feeding on unhygienic food sources, like human faeces, which can then contaminate surfaces and food that they walk over.

They have a tendency to vomit partially digested food, and regularly leave faeces on floors, benchtops, and food sources.  Finally, they also produce a musty, oily smell that typically worsens the longer they stay in your home or workplace.

According to the WHO, all these factors mean cockroaches are responsible for the transmission of diseases such as:

  • Diarrhea
  • Dysentery
  • Cholera
  • Leprosy
  • Plague
  • Typhoid fever
  • Various viral diseases
  • Parasitic worms
  • Various types of fungi

They can also cause allergic reactions, which can trigger dermatitis, eyelid swelling, and breathing problems.

Types of Cockroaches on the Gold Coast

In Australia, there are about 450 species of cockroaches, but only three of them are common pests.  If you see any of the following cockroaches in your home, consider hiring a professional pest control service to help eliminate them.

German Cockroaches

The first thing you need to know about German cockroaches (Blattella germanica) is that they aren’t actually German.  They originated in Africa, and have subsequently spread around the world, which tells you a lot about their durability and survival skills.

These small, tan-coloured cockroaches are typically between 1.1 and 1.6 centimetres long, and are the most invasive of all cockroach species.  Their small size allows them to hide and breed in places larger roaches can’t; females also carry their eggs, rather than laying them on an object, which makes them harder to eradicate.  

Often, German cockroaches can be found in large groups, especially around warm objects like fridges, coffee machines, and water heaters.  Females carry around 40 eggs, with an annual reproductive rate of about 20,000 eggs per year.  Nymphs (baby roaches) mature within about 60 days of birth, making German cockroaches one of the most prolific pests that you’ll ever encounter.

Unlike other pests, which prefer certain seasons, German cockroaches will invade your building during literally any time of the year.

American Cockroaches

American cockroaches (Periplaneta americana) are one of the larger species of cockroaches in Australia, clocking in at between 2.9 and 5.3 centimetres in length. 

Their reddish-brown wings and white-stroked heads are instantly recognisable to most people – you’ve almost certainly come across one in your Gold Coast property before. 

Although these cockroaches aren’t quite as bad as German cockroaches, you still definitely want to avoid having them in your home.  They lay about 10 eggs per clutch, producing about 150 eggs per year and maturing at 6­–12 months. 

Note the yellow stripes on the upper third of the wings.

Australian Cockroaches

Australian cockroaches look very similar to American cockroaches, although they’re smaller (2.3–2.5 centimetres) and have yellow strokes on the edges of their wings as well as their heads.

Don’t worry, you won’t be exterminating anything native when you kill these roaches.  Despite the name, Australian cockroaches are actually from Africa, but now inhabit tropical climates around the world.    

Tips to Prevent Cockroach Infestations

Although it’s impossible to stop every cockroach from getting inside, these simple tips will help you prevent any major cockroach incursions.

  1. Clean up food scraps.  It shouldn’t be surprising that food crumbs and spills attract vermin, and cockroaches will be the first pests on the scene.  If you wipe down food surfaces when you’re finished, regularly wash the floor, take the rubbish out daily, and do the dishes each night, you’ll cut down on cockroaches, flies, and rats, as well as associated predators like spiders.
  2. Keep food in sealed containers.  Still having roach problems?  Make sure all your food (including fruit) is stored in plastic containers or in the fridge.  Cockroaches can chew their way through carboard and plastic wrap.
  3. Seal up entrances.  To keep roaches and other pests out of your house, make sure your windows and doors are fully sealed when closed; consider investing in DIY door seals.  If you have cracks in your exterior walls, close them up with concrete or sealant.
  4. Eliminate moisture sources.  Cockroaches require a water source to survive, so any dripping pipes or leaky taps will make your home a more desirable habitat for them.  Most leaky pipes can be fixed by tightening or replacing seals, but, if you think the job’s too complex, pay a handyman to come and do it.  You’ll save water, prevent mould, and reduce your risk of cockroaches, termites and ants.      
  5. Conduct regular deep cleans.  Cockroaches are notorious for living in appliances and machinery, so make sure you regularly clean behind things like your microwave, fridge, and coffee machine.  If you can easily access the interior of your appliance, do so – food scraps and coffee grind can collect in very unusual places.
  6. Declutter your house.  More objects lying around your house means more dust, more difficulty cleaning, and more dark corners for pests to hide.  One of the easiest shortcuts to a cockroach-free home is to put as much as possible into sealed cupboards and storage spaces.             

Cockroach Pest Control FAQs

How much is cockroach pest control on the Gold Coast?

The cost of cockroach pest control varies depending on factors like:

  • Whether your property is commercial or residential
  • The size of your property
  • Whether you want a preventative treatment or need an infestation destroyed
  • The type of cockroach
  • The accessibility of the infestation site

For example, the occasional American cockroach might be be deterred with an annual residual pest treatment, whereas a serious infestation of German cockroaches in the back of your fridge could require a more complex approach.

On average, cockroach pest control on the Gold Coast ranges from $150 to $300.  At Arena Pest Management, our general pest control service (which also kills and prevents ants and spiders) starts from just $140 for a four-bedroom home. 

How do I get rid of cockroaches in Queensland?

Like ants, cockroaches are typically drawn into homes and businesses by three things:

  • Food
  • Water
  • Shelter

You can start by removing their food sources.  Cockroaches are indiscriminate omnivores, which means they’ll eat almost anything you leave around, including food scraps, spilled sauce, grease, other insects, faecal matter, and fruit.

Always clean up after you’ve finished cooking.  Wipe away any water or food spills or scraps; pay particular attention to food that’s fallen on the floor.  If you have fruit, try storing it in the fridge or in a sealed container to prevent it from being contaminated.

You can also make your home inhospitable for cockroaches through regular repellent pest treatments.  Insects and arachnids can detect repellent insecticides, which means they’re much less likely to even enter your building – and, if they do, they’ll soon succumb to the residual poison.

Does pest control keep cockroaches away?

Yes, professionally implemented pest management does keep cockroaches away.  Repellent insecticides are a type of insecticide used by pest technicians that bugs can detect – they know there’s poison around, so they’re much less likely to come in the house.

However, if you have an active cockroach infestation, a repellent insecticide might not be the best choice.  Cockroaches are communal insects, which means there isn’t just one lurking around – there’s probably a whole nest of eggs and gravid females hiding somewhere that you can’t see. 

In situations like these, a non-repellent treatment option (like baits) is the best way to ensure that you kill the whole nest, not just the cockroaches that are out in the open.    

How long does it take for pest control to get rid of cockroaches?

The speed of extermination depends on the extent of your cockroach infestation and the type of treatment used.

Direct treatments such as sprays will kill the target cockroach in a matter of minutes, but will leave the rest of the nest untouched.  Indirect treatments, such as bait stations and gels, take longer, but will typically wipe out the rest of the infestation (including gravid females) in a few weeks.
