Cockroach Pest Control.

Why are cockroaches considered a pest?

Cockroaches have cohabitated with people over time and thus made them considered a pest.

The reasons that cockroaches are considered a pest are due to the following: fear, contamination of food, odour caused by large populations, allergic reactions, disease transmission and just being plain annoying.



First Strike Pest Control technicians will inspect and advise the client of a treatment plan using liquid, gels and dust to gain control.

Areas of treatment:

On initiating a pest treatment, we will apply liquid insecticide to the external area of the home and to the skirting area within the structure. Gels will be applied to kitchen cabinetry and dust dispersed throughout the roof void and subfloor (if there is one). Particular attention is paid to where the client has seen the activity.




American Cockroach:


Warm, moist dark areas such as steam ducts, drains, sewers and grease traps. Indoors they infest bakeries, abattoirs, food factories, restaurants and hospitals, and all areas including roof spaces. In warmer climates, they infest outdoor areas and are often found in garbage dumps, outbuildings, woodpiles and palm trees.


 The American cockroach’s ootheca is dark brown then black and is on average about 8 mm long – wider and darker than the ootheca of the German cockroach. The adult is reddish to chocolate brown and is usually 30–40 mm long. Its wings are fully developed and extend beyond the abdomen. It has a yellow band on the pronotum. The American cockroach is the largest of the pest cockroach species. American cockroaches can coexist with German cockroaches with no negative effects on either cockroach population.

Australian Cockroach:


The Australian cockroach is usually found outdoors, under bark and in woodpiles and locations with moist and decaying vegetable matter. Inside it can be found in cupboards, behind drawers and in all food areas. It prefers warmer, humid environments.

Australian cockroach nymphs are initially brown and wingless, with later instars becoming more like adults in shape, colouring and size. Later instars have distinct bright yellow spots along the edges of their abdomen. The adult is similar in appearance to the American cockroach but slightly smaller, 30–35 mm in length. Its wings are fully developed and extend beyond the abdomen. It has a distinctive pale yellow ring on the pronotum and a pale yellow margin on the front edges of each forewing. 


German Cockroach: The German cockroach’s egg case (ootheca) is brown and is usually less than 6–7 mm long. Nymphs are dark brown to black, with distinct dark parallel bands running the length of the pronotum (shoulders) and yellowish in the centre. Nymphs do not have wings. The adult cockroach is light tan to medium brown, 10–15 mm in length. Wings cover the entire abdomen but they do not fly; there are two dark parallel stripes on the pronotum behind the head. The German cockroach is the most common cockroach in Australia


Oriental Cockroach:


Oriental cockroaches prefer cool, damp areas and are common in temperate climates. They are often found outside in the garden or in and around rubbish bins, drains and sewers. Inside, they are more commonly seen beneath the floor or in other cool areas such as basements and foundations.

 The oriental cockroach produces a dark, reddish-brown, slightly puffy ootheca that is 8–10 mm long. The adult is shiny dark brown to black and measures 20–30 mm in length. The shorter male has long, functional wings, covering two-thirds of its abdomen, while the wider-bodied female has short wings and cannot fly. This species cannot climb


Brownbanded Cockroach

Kitchens, laundries and food preparation areas – dry and quite warm locations.


The smoky-brown cockroach’s ootheca is dark brown to black and is on average about 10–14 mm long. The adult is uniformly shiny, blackish-brown and measures 30–35 mm in length. Wings are fully developed and extend beyond their body; they are strong fliers. They are prone to dehydration, so the availability of a moist environment is essential for survival. They are common around Sydney
