Cockroaches are Melbourne’s most reported household pest and the number one cause of council health enforcement action in food businesses. They spread Salmonella, E. coli, and Staphylococcus bacteria across food preparation surfaces and trigger asthma and allergy attacks — particularly in children. AD Pest’s licensed cockroach specialists use gel bait, residual spray, and crack-and-crevice treatment to eliminate German and American cockroach infestations fast, with child-safe products and same-day service available across Melbourne and Victoria.
Signs You Have Cockroach
- Small dark oval droppings (resembling ground coffee or black pepper) found in kitchen cupboards, under appliances, or behind the fridge.
- A distinctive musty or oily odour in enclosed spaces like cupboards, drawers, or wall cavities — this smell intensifies with larger infestations.
- Oval-shaped egg cases (oothecae) found behind fridges, under sinks, or in dark confined spaces — each case contains 15–40 eggs.
- Live cockroaches seen at night when lights are turned on — cockroaches are nocturnal; seeing them in daylight indicates an overcrowded infestation.
- Grease marks or dark smear trails along skirting boards, wall junctions, or behind appliances — left by cockroaches as they travel their regular routes.
- Shed exoskeletons — cockroaches moult several times as they grow; shed skins near harbourage sites confirm an active infestation.
Common Cockroach Species Found in Melbourne & Victoria
German Cockroach (Blattella germanica)
The most common indoor cockroach in Melbourne homes, apartments, restaurants, cafés, and commercial kitchens. German cockroaches reproduce extremely quickly and are often found behind refrigerators, dishwashers, microwaves, and inside cupboards. A single infestation can grow into thousands within months if left untreated.
American Cockroach (Periplaneta americana)
One of the largest pest cockroach species found in Victoria. American cockroaches are commonly found in drains, sewers, basements, subfloors, warehouses, and commercial buildings. They can fly short distances and are often attracted to warm, damp environments.
Australian Cockroach (Periplaneta australasiae)
Common throughout Victoria, particularly during warmer months. Australian cockroaches are frequently found in gardens, sheds, garages, roof voids, and around outdoor entertainment areas before moving indoors in search of food and moisture.
Smokybrown Cockroach (Periplaneta fuliginosa)
A large flying cockroach occasionally found in Melbourne, especially around roof voids, gutters, trees, and outdoor structures. They prefer humid environments and can enter homes through open windows and doors.
Brown-Banded Cockroach (Supella longipalpa)
Less common than German cockroaches but still found in Melbourne homes and offices. Brown-banded cockroaches prefer warm, dry locations and are often discovered in cupboards, wardrobes, electrical equipment, and furniture.
Oriental Cockroach (Blatta orientalis)
Sometimes called the “water bug,” this species prefers cool, damp environments such as drains, basements, subfloors, and sewer systems. They are slower moving than other cockroach species but can still pose significant hygiene risks.
Wood Cockroaches
Wood cockroaches are generally outdoor species found under mulch, bark, firewood, and garden debris. While they occasionally enter homes, they rarely establish indoor infestations.
Not Sure Which Cockroach You Have?
Our licensed technicians identify the species before treatment because different cockroach species require different control methods. Correct identification ensures faster results and long-term protection.
Why It Happens / Risk Factors
German cockroaches (Blattella germanica) thrive in Melbourne kitchens because they require warmth (24–30°C), moisture, and food — all present in kitchens and bathrooms year-round. They reproduce exponentially: a single female and her offspring can theoretically produce 30,000 descendants in a year. They enter buildings through grocery bags, second-hand appliances, cardboard boxes, and gaps in plumbing. American cockroaches (Periplaneta americana) are larger, typically found in drains, sewers, and sub-floors, and move into buildings during heavy rain. Both species build resistance to over-the-counter insecticides quickly, making professional gel bait rotation essential.
Health Risks
⚠️ EEAT signal — reference official sources (CSIRO, Vic Health, Victorian Food Act 1984 where applicable)
Cockroaches are classified as public health pests under the Australian Food Standards Code. They carry Salmonella, E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa on their bodies and contaminate every surface they traverse. Their cast skins and faeces are potent allergens — a leading trigger for childhood asthma and year-round allergy symptoms. For commercial food businesses in Victoria, a cockroach sighting during a council health inspection can result in an improvement notice or temporary shutdown under the Victorian Food Act 1984 and Food Standards Code Standard 3.2.2.
Our Treatment Process
Species Identification & Inspection
We identify the cockroach species before treatment — German and American cockroaches require very different approaches. We inspect harbourage sites, entry points, harbouring conditions, and population density using a thorough inspection protocol.
Gel Bait Application
We apply professional-grade cockroach gel bait (Maxforce FC, Advion, or equivalent APVMA-registered product) in crack-and-crevice locations: under appliances, in cupboard hinges, behind sinks, and around plumbing penetrations. Gel bait eliminates the entire population including egg cases through secondary kill.
Residual Spray Treatment
We apply a residual insecticide to harbourage surfaces, floor-wall junctions, sub-floor vents, and external entry points. Rotation of active ingredients prevents resistance build-up — critical for German cockroach control.
HACCP Documentation (Commercial)
For food businesses, we provide full HACCP-aligned treatment documentation including product name, APVMA registration, application method, site map of treatment locations, and technician licence number. This documentation satisfies Food Safety Supervisor and council health inspector requirements.
Follow-Up & Guarantee
We recommend a follow-up visit at 2–4 weeks for German cockroach infestations, as egg cases can survive initial treatment. Annual plan subscribers receive unlimited callbacks — if cockroaches return within the guarantee period, we treat again at no charge.

Cockroach Control Questions Answered
Everything VIC homeowners ask about cockroach control, inspections, and treatment options.
How do you get rid of cockroaches in a Melbourne kitchen?
Professional cockroach control in a Melbourne kitchen involves gel bait applied in crack-and-crevice locations (under appliances, in cupboard hinges, behind sinks), combined with a residual spray to harbourage areas. Gel bait is child-safe and food-safe when applied correctly. The entire process takes 30–60 minutes and you can use the kitchen the same day. Follow-up treatment at 2–4 weeks ensures egg cases are eliminated.
Are cockroaches dangerous in Melbourne homes?
Yes. Cockroaches carry Salmonella, E. coli, and other bacteria on their bodies and contaminate food preparation surfaces as they move. Their shed skins and droppings are potent allergens — a documented trigger for childhood asthma and allergy attacks. For food businesses in Victoria, cockroaches found during a council health inspection can trigger enforcement action under the Victorian Food Act 1984.
What is the difference between German and American cockroaches?
German cockroaches (Blattella germanica) are small (12–15mm), tan-coloured, and live exclusively indoors — primarily in kitchens and bathrooms. They reproduce rapidly and build resistance to insecticides quickly. American cockroaches (Periplaneta americana) are much larger (35–40mm), reddish-brown, and typically live in drains, sewers, and sub-floors, entering buildings during wet weather. Treatment methods differ significantly between the two species.
How long does cockroach treatment take to work in Melbourne?
Gel bait begins killing cockroaches within 24–48 hours of first feeding. Full elimination of a German cockroach population typically takes 2–4 weeks, as egg cases must hatch and newly emerged nymphs must feed on the bait. A follow-up visit at 3–4 weeks after initial treatment ensures egg cases are addressed. Severe infestations may require a third treatment.
Do I need to leave my home during cockroach treatment?
No. Professional cockroach gel bait treatment does not require you to vacate the property. We apply gel bait in concealed locations inaccessible to children and pets. Residual spray treatment may require a 30–60 minute airing period before re-entry to treated rooms. Our technician will advise you of any specific precautions for your property.
