When it comes to German cockroaches, they rank in the top five insect pest inquiries for homes, businesses and other institutions. These are the kind of roaches that live in apartments, houses, grocery stores, restaurants, hospitals and other buildings were food is being prepared, served or stored. These cockroaches don’t discriminate when it comes to food, as they’ll eat anything.
German cockroaches can move into a new location by hitching a ride on soft drink cartons, egg cartons, beer cases, potatoes, onions, used furniture and more. During the summer time, they are actively moving from one location to another.
German cockroaches can quickly increase their populations and live in all rooms of the home, most especially the bathrooms and kitchen. They’re a real nuisance because they damage books and wallpaper as well as fouling food. They eat the glue found on furniture, and they give off a nasty-smelling odour.
Worst of all, some people are allergic to german cockroaches, and they can be responsible for many cases of childhood asthma. They also carry diseases – meaning any food that has been contaminated by german cockroaches can result in diarrhoea, dysentery and/or food poisoning.
GERMAN COCKROACH IDENTIFICATION
German cockroaches have a flat, oval shape, long antennas and spiny legs. In the early stages of a german cockroaches’ life span, they still look like adults but are only smaller and don’t have developed wings.
Adult German cockroaches appear to have light tan or have a medium brown colour. The only difference is its shield behind its head. It’s got two dark stripes, which are separated by one lighter stripe. These stripes run the entire distance of the cockroach’s body. They measure around 1.27 centimetres to 1.58 centimetres long with wings (although they don’t generally fly).
The entire stomach region of the female german cockroach is covered by its wings; the wings of the male cover all but the stomach tip. The male german cockroach has a light brown colour and looks like a boat; females have a darker colour with a round posterior.
Young german cockroaches, known as nymphs, don’t have wings. They are practically black although they do have one light stripe that divides to black bands that run down the middle of its back. The egg capsules have a light tan colour and measure no more than 0.7 cm long
HABITS & LIFECYLE
Typically, cockroaches hide during the day – in closets, cracks of closets, cabinets or pantries and behind baseboard moulding. They can also be found under dishwashers, refrigerators and stoves. If many roaches are seen in the day, you can bet the population is big.
The activity level of both the adults and nymphs is high and they can scurry quickly.
This cockroach needs moisture and can travel up to 4 meters from their home to find water and food. However, they prefer to stay in the shadows, as not to be seen. Without a food or water source, the adult cockroach can die within a couple of weeks. With just water as a source, they will live for up to a month.

HOW TO PREVENT COCKROACH INFESTATION
Most of the time, Geram cockroaches are introduced into your house by being brought in in boxes or a 2nd hand appliance.
Before you bring in boxes, cartons, sacks, furniture and appliances, inspect them for roaches and egg cases.
It’s vitally important to keep your home clean – a dirty dwelling is more susceptible to roach infestation than a clean home. Here are some things you can do to prevent roaches from entering your building:
– Clean every part of your home that you can – sinks, refrigerators, stoves, cabinets, food storage bins, pantry shelves and more
– Clean spilt food or beverages up right away
– Don’t leave food scraps on dirty dishes and on countertops during the overnight hours
– Food should be kept in tightly sealed containers
– Cans and bottles are rinsed before placed in the trash
– Have the garbage containers moved away from the home or building
– Put leftover pet food away – do not keep it in their feeding dish during the overnight hours
GERMAN COCKROACHES HAVE HEAVY RESISTANCE
As it stands right now, it’s just the German cockroach that has become resistant to many of the current control problems. For that reason, people often think that spraying more insecticide will help in controlling the pests. This only leads to more resistance with the cockroaches. Therefore, you should never “up” the dosage amount.
Even if you do kill the susceptible roaches, there is always that one resistant roach that becomes a part of the rest of the population. As such, insecticides previously used to control these roaches do not work anymore because of the altered population – the parent passes the resistance on to their children.
HOW TO DETECT GERMAN COCKROACH INFESTATION
When you contact Sydney’s Best Pest Control and inform them you have an issue with the small (German) cockroaches your consultant will ask you what rooms you are seeing them in. This is because severity is based on the rooms you are seeing them in and how far away from the wet rooms they have travelled.
The further the cockroaches move away from water the larger their populations. Once their nests become over crowded they are forced to go into rooms where there is no easy water supply.
Mild: Kitchen, bathroom and laundry
Moderate: Kitchen, bathroom, laundry, lounge room and hallway
Severe: Throughout the entire premises including the bedrooms.
Internal: We use a gel/paste that is placed inside the hinges of the cupboards, around the affected rooms in specific areas and behind your appliances. A non-repellent spray will also be applied to the skirting boards of the affected rooms which acts as a barrier for any wandering German cockroaches which would prevent them from spreading into unaffected rooms.
How Does the Gel Work?
The gel is placed in the hinges of the cupboards and behind your appliances using a syringe and then hardens. The German cockroaches see this gel as a food source and will feed on it.
As cockroaches lick themselves clean, when they go back to the nest and other cockroaches start the cleaning process the chemical is passed amongst each other inside the nest.
Preparing for The German Cockroach Treatment
Internally: Clean up internally, clean behind the fridge if accessible and under the microwave. Limit the clutter within the house as having a cluttered house can introduce pests to your home and become a harbourage area for pests. Limit paper goods and throw out cardboard boxes and plastic bags
What to Expect After a German Cockroach Treatment
German cockroaches will be flushed out and will continue for up to 6 weeks, which is what you want. You do not want the German cockroaches to continue to hide.
It is common to see baby German cockroaches coming out at the 4-week mark which is entirely normal and not a cause for alarm or that the treatment is not working.
You should notice a 70-80% reduction in the first week and over the next 6 weeks, this will continue to decrease.
If your premise has a severe case of German cockroaches, i.e. they have spread to the bedrooms the follow-up treatment should be conducted 6 weeks after the initial treatment.
Do not be alarmed if you do not see any dead cockroaches – as it is possible that they will die within their nests.
