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 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


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.


One of the best systems to controlling the German cockroach population is the Integrated Pest Management system.  It uses a combination of both preventive, non-chemical pest control methods and the least dangerous pesticides for both human health and the atmosphere. While it doesn’t get rid of them entirely, it’s a better approach to conventional pest control measures.  In times’ past to eliminate these pests, pesticides were the only things used. What happened is this:

- Some of these pests became a resistance to the chemicals used.

- Created instances of human exposure to the dangerous chemicals

- Became a threat to species not targeted

- Environmental contamination

- Pesticide waste

However, with IPM, there is routine inspection with treatment being provided only when the pests are seen. This decreases the use of conventional routine, pesticide application treatments when the pests are seen or not.

With the IPM plan, glue boards and sticky traps are used to watch the activity of cockroaches. These things are placed in a building where roaches are typically found:

- Cabinets

- Under pipes

- Under appliances

Good habits for cockroaches are tight cracks of around 0.952 centimetres or smaller. Monitoring of these roaches will determine if they are present and if the practices to control them are working. Other IPM tools include baits, caulking, vacuum cleaners and insect growth regulators.


Remember, German cockroaches move from buildings in the summertime, getting into the new dwelling through foundation cracks, along gas and water pipes and around loose-fitting windows and doors. If you want to prevent a cockroach infestation, be sure you fix any leaky pipes, seal cracks in the windows, doors, ceilings, electrical outlets, baseboard, floors, foundation walls, etc.  You can do this by using putty or any other kind of caulking material.

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


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.


Severity Levels

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.

These guys were top notch and I would recommend them to anyone in the surrounding area. I called 6 or so places to see if they could come same day for spider removal, and everyone said they were booked solid until next week. I had guests staying with me that day, so i wanted to avoid having dozens of spiders roaming around my apartment. Sam told me he'd try to squeeze me in he just had to double check. He called me back 5 minutes later and said I could expect someone in just an hour or so. They were professional, reliable and very honest.

A company offering free advice, without pushing for business, is very refreshing. After examining photos of a pest problem I was experiencing, Sam from Sydneys Best Pest Control, phoned me to discuss the matter. His advice was to take my photos to my local hardware store to obtain the correct product to treat the problem myself. There was no pressure to use the services of his company.I was very impressed with Sam’s knowledge and professionalism. After this experience, I would certainly use the company for my annual pest control treatment.

I'm so glad to have found SBPC after struggling to find a decent pest control company who is NOT all about money or take advantage of their customers. This is the best company by far and I'd dare say it's up there in the industry with other 25-30+ odd years businesses that I have encountered. You got my business and keep doing what you do best!

I was happy with the service provided by Sydney's Best Pest Control. Easy to make a booking and the technician was on time, friendly, informative and did his job efficiently. I did find that they called and emailed more times than I would have liked, and although they offer warranty, I felt they were quite reluctant and offended when I asked for the technician to come back after I was concerned with still seeing cockroaches running around 6-8 weeks later. I still highly recommend the company, as their product is great and they were professional. I would book them again if we move.
