There are actually 5 principal pest species of cockroach australia wide, all introduced & providing under 1 per cent of the four hundred and fifty varieties present in Australia. They include: German, American Smoky-brown, Brown-banded and of course the Australian species.
Their particular insect order is known as Blattodea & evolved from termites more than three hundred million years back. A species known as the "Oriental Cockroach" (scientific name: Blatta orientalis) had been a pest species, however is currently seldom experienced, so it won't be mentioned here.

I'm often asked by my clients, "I've heard that cockroaches are clean because of their habit of grooming? Is this true?"
I answer; "No, they actually crawl through sewers, garbage & rubbish bins. They eat our food and transmit such diseases as Diarrhoea, Salmonella, E. coli,and pneumonia.
Other risks are hookworm, tapeworms & viruses. Cockroaches may also cause allergies and asthma attacks.

CONTROL: Inspection is a very important part of cockroach control. Have you noticed any particular trouble areas? If so, then inspect all known cockroach harbourage areas such as:
- cracks and crevices in and around kitchen, bathroom and laundry and meal preparation sites if on a commercial building
- behind hot water services
- electrical appliances such as ovens, refrigerator motors, microwaves, stereos etc.
- door hinges
- behind wallpaper or ply veneer boards
- drains and plumbing; and
- roof voids
Treat cracks and crevices in all of these areas and any other harbourages with insecticidal dusts to flush out the cockroaches and/or in conjunction with safer residual sprays such as Permethrin. Use dust for electrical items & always use a non-fuming synthetic pyrethroid spray such as Cislin 10 for inside treatments. Heavy infestations may require a misting or a gassing for a faster kill.
WARNING: DO NOT UNDER ANY CIRCUMSTANCE TREAT ANY FOOD PREPARATION AREAS, FOOD UTENSILS,CLOTHES, BEDDING, OR ANY OTHER AREAS NOT DESCRIBED ON THE PESTICIDE LABEL.
GERMAN COCKROACH INFORMATION SHEET
German Cockroaches are the world's most successful and prolific cockroaches because of their extremely fast breeding habits and ability to adapt to almost any environment. They will eat anything that humans do and will also eat wallpaper, curtains, leather and any other organic material. They are always found indoors and tend to stay where food and water are freely available, such as kitchens, pantries and bathrooms, etc. They cannot fly and carry their egg capsules (Ootheca) until maturity, unlike the other pest species.
IDENTIFICATION:
The adults are 10-15mm long and are tan to medium brown coloured with 2 parallel dark stripes on the head section (Pronotum). The nymphs are very small, dark and beetle-like when they first emerge from the capsule and within a few weeks grow more slender and lighter coloured. They have a light stripe down the centre at this stage of their development. Signs of infestation include cast skins, dark regurgitation and faecal droppings in corners and door hinges of cupboards. Their droppings are tiny and resemble fly-specks. They are often confused with the Brown-banded Cockroach which is lighter in colour, lives outdoors or indoors in dry environments and can fly.
PREVENTATIVE MEASURES TO ENSURE PERMANENT CONTROL
Once you have employed a professional pest control company such as A1 PEST CONTROL to control German Cockroaches in your environment, there are certain things that you can do in order to get a faster, more permanent result. We have used our professional equipment and insecticides to get to the places that you would not normally even think of, let alone carry out. Once we have gone there are three measures that you can do to achieve this result. These 3 things are:
- KEEP THE AREAS WHERE COCKROACHES HAVE BEEN FOUND SCRUPULOUSLY CLEAN

This involves keeping the floor and other areas free of food scraps and grease. Washing up should not be left overnight and food should never be consumed in any place other than the meal area. Cardboard and paper are notorious for harbouring German Cockroaches. Do not store these for any period longer than necessary. - FILL GAPS OR BLOCK ANY CRACKS & CREVICES WHICH MAY PROVIDE HIDING SPOTS FOR COCKROACHES
You can do this with a caulking agent such as "No More Gaps." Replace washers on dripping taps as this can provide their dringking water. - ONE MONTH TO SIX WEEKS AFTER TREATMENT USE SURFACE SPRAY INSIDE THE CUPBOARDS OR COCKROACH BOMBS.
Still go ahead and carry this out
EVEN IF NO COCKROACHES ARE SIGHTED AT THIS STAGE!
Doing this will break their life cycle and hasten their demise. Remember to close off the infested areas as much as possible when using bombs to keep as much of the smoke contained. -Sheets may be used when pinned to doorway frames when doors are absent. Always read and take note of the instructions on the label. In badly infested situations, (i.e., when cockroaches are sighted in numbers during the day) repeat this treatment in a further month.
Remember that cockroach control relies upon a conscientious effort from both the pest control operator and the client. Success definitely doesn't occur overnight but following these few instructions will get you very good results within one month of our treatment and guarantees that you won't be living with these unwanted guests in the future!
