Cockroaches: Why They Invade Your Home & How to Get Rid of Them

Cockroaches are one of the most common pests we deal with in Queensland, and for good reason — our warm climate provides the perfect environment for them to thrive. Whether you’re seeing them in your kitchen, bathroom, roof void, or even during the day, cockroaches are a sign that something in the home is attracting them or allowing them to breed.

At CB Pest Control, we specialise in eliminating cockroaches and breaking their breeding cycle using professional products, IGRs, and targeted treatment methods.

Why Cockroaches Enter Your Home

Cockroaches are attracted to three main things:

1. Food Sources

Crumbs, pet food, grease, spills, and even rubbish left overnight attract them.

2. Moisture & Water

They thrive in bathrooms, kitchens, laundries, and leaking pipes.

3. Shelter

Cockroaches love tight, dark spaces like wall cavities, cardboard boxes, cupboards, drains, and roof voids.

Even the cleanest homes can get cockroaches — they hitchhike in grocery boxes, appliances, school bags, or simply wander in during warm nights.

Signs You Have a Cockroach Problem

• Droppings (small black pepper-like specks)
  
  

• Smear marks in damp areas
  
  

• Unpleasant “musty” odours
  
  

• Shed skins or empty egg casings
  
  

• Cockroaches seen during the day (a major red flag)
  
  

• Damage to food packaging
  
  

If you’re seeing them regularly, an active infestation is already present.

How to Prevent Cockroaches Around Your Home

1. Clean Food Sources Daily

Wipe benches, sweep floors, store food in sealed containers, and keep bins closed.

2. Fix Moisture Issues

Repair leaks, dry sinks nightly, and ventilate bathrooms.

3. Reduce Clutter

Boxes, paper bags, and stored items create perfect hiding spots.

4. Seal Entry Points

Fix gaps around doors, windows, plumbing, and vents.

5. Keep Drains Clean

Cockroaches often nest in drains and plumbing voids.

These steps reduce cockroach pressure — but they will not eliminate an established infestation.

How CB Pest Control Treats Cockroaches Professionally

A professional cockroach treatment must target both adult roaches and their breeding cycle. Here’s how we do it:

✔ Targeted Insecticide Application

We apply long-lasting, professional-grade sprays to high-risk areas such as skirting boards, cracks, crevices, and roof voids.
These products are far more effective than supermarket sprays and are designed for long-term control.

✔ Cockroach Gels

We place gels in cupboards, kitchens, pantries, and electrical appliances where sprays cannot be used safely.

✔ Insect Growth Regulators (IGRs)

IGRs stop roaches from reproducing by preventing eggs from hatching and juvenile roaches from developing.
This is essential for breaking the life cycle, not just killing the adults you see.

✔ Dusting Roof Voids & Wall Cavities

We use specialised dusts to treat hidden areas where cockroaches breed.

✔ Species Identification

Different species require different approaches.
German cockroaches, for example, breed extremely fast and require a more aggressive gel/IGR program.

Why Eliminating Cockroaches Is So Important

Cockroaches can:

• Spread bacteria and pathogens
  
  

• Trigger asthma and allergies
  
  

• Contaminate food
  
  

• Spread germs across benches and surfaces
  
  

• Reproduce extremely quickly if untreated
  
  

A single female German cockroach can produce thousands of offspring in a year.

The sooner you act, the easier and cheaper it is to get them under control.
