German Cockroach (Blatella Germanica)

What is the proper approach when cockroach control in London is required?

One of the last pests you want to find inside your home is the cockroach. These small, highly adaptive pests are difficult to get rid of in many instances and are hardy survivors who are built to survive incredibly harsh environments.

Their creepy appearance is especially off-putting for many and as soon as you see one, you’ll want to get rid of it as soon as possible. Cockroach removal and cockroach treatments are often passed to a professional pest control company in London as of the impact they might have on homes and businesses.

This is especially true for the German cockroach, which is typically one of the smaller species of cockroach. If you notice an infestation of these pests, you’ll want to act fast so that the infestation does not get out of control. A single German cockroach can quickly become hundreds, and they’ll be even harder to get rid of – sounds like a pest problem, right?

So, what makes the German cockroach such a hardy pest? Let’s take a closer look at their features and characteristics, how they may have gotten inside your house, and why they’re there. How big the cockroach problem can become and is the bait gel best for the pest control treatment? Keep reading to learn everything you need to know about the German Cockroach and how to get rid of them.

Features and Characteristics


Considered as common, the cockroach is one of the smaller species of cockroach, with males reaching sizes of 1.1 to 1.6 cm. Females typically reach sizes of 1 to 1.5 cm in length. Their coloring varies from tan, to dark brown or almost black. They typically have two darker streaks of coloring running down their backs.

Nearly flightless, the German cockroach may use its wings to glide when it needs to make a quick escape, but they cannot actually fly with them. With their wings, coloring, and appearance, they may appear very close to the oriental cockroach, however, they are much smaller.

These cockroaches typically are attracted to food sources like meats, starches, sugars, and fatty foods. They are highly adaptive, and in instances where food is scarce, they will even feed on household items like soap, glue, or toothpaste. In extreme conditions, they will become cannibalistic and turn to eat each other for survival.

To top it all off, the German cockroach can reproduce at a much faster rate than any other species of cockroach, making them a huge problem once they’ve decided to stick around. Under ideal conditions, by laying egg cases, they will mature from egg to reproductive adult in around 50 to 60 days.

Upon fertilization, the female German cockroach will develop of ootheca in their abdomen, which will grow and swell as the eggs develop. She will eventually deposit the ootheca in a safe, warm space and the egg will continue to develop until it is ready to hatch. It will appear clear in color at first but will then turn white until it darkens and gains its reddish-brown color.

The first nymphs hatched will undergo several stages of development, which is a process with a high fatality rate. Nearly half of all nymphs hatched will die before they reach sexual maturity. Molted skins and dead nymphs will be consumed by other nymphs as they continue to develop and reach adulthood. Our pest technicians will be able to explain how cockroach infestations are formed and how cockroach pest control services are usually carried out.

How Did They Get In?


Being relatively small as far as pests go, Germanic cockroaches can come into your house in a variety of ways. An unused drain may let plenty of them in, as they typically tend to infest sewers and will have easy access through pipes. Our cockroach exterminators are able to inspect those areas via various innovative methods.

They may also have come inside from the surrounding outdoor area, especially if the surrounding land is covered in wet leaves, damp undergrowth, or rotting trees. Any tiny hole or gap in the exterior of your home would be enough to let them inside, or they may have clambered through an open window or an open door when you weren’t looking.

Why Do You See Them Around Your Home and Are They Dangerous?


The German cockroach is attracted to human buildings of all kinds, but will particularly target restaurants, food processing facilities, hotels, and institutions like nursing homes. This is especially true in cold climates, as they will occur only in human buildings and cannot survive well in the cold.

They come inside in search of food, and as we mentioned earlier, will typically scavenge for meats, sugars, and fatty foods. They even like to eat other household items that we wouldn’t typically consider food.

The German cockroach is not inherently dangerous to humans, lacking any venom or pincers strong enough to cause us any harm.
