German Cockroach Infestation

Having a home is a big responsibility. Bringing in groceries, paying bills, mowing the yard and other endless house chores are always waiting for you. Taking care of cleanliness and hygiene is a big essential point. Hygiene differs from area to area in the sense that kitchen hygiene is different from bathroom hygiene. Cleanliness and hygiene is a very important aspect as the health of the inhabitants is directly dependent on the hygiene degree of the house where you live. If there are poor hygienic conditions it will reflect on your health. In contrast, if your house’s hygienic conditions rate well and good on the scale, then your house inmates will have good health, relatively speaking.

German cockroaches are fairly common pests and it is not rare to find them in your house. There is no need to be afraid but there is need to be cautious. Cockroaches are filthy creatures and are a good mode of transmission to spreading diseases. Let’s know more about these vermins.

Are German cockroaches able to bite human beings?

Cockroaches have been categorized as omnivore creatures. In more simple terms, cockroaches have been known to eat non – vegetarian as well as vegetarian food. They are most likely to eat meat and plants. Every once in a while I am pretty sure this question might have popped in your mind: Do cockroaches bite? Well, the best answer that I can give you is that it depends on the situation. Obviously, cockroaches do have teeth. They are not known to bite human beings discounting some exceptional situations. German cockroaches are attracted to places where food is easily available. In a house, kitchen or a pantry is the most common place to find German cockroaches. German Cockroaches are not known to human beings as such but situations have come across from history and past times suggesting some such activities. Let me elaborate.

These cockroaches are attracted to easily available food and dirty conditions, as it was earlier stated. It has been noted that German cockroaches have infested ships as the surroundings are not as clean as a normal house. Now in a ship food is limited meaning it might be available easily but not for a long time. When the food starts becoming scarce and it becomes difficult to survive, these cockroaches become aggressive. A point to be noted here is they might come in certain numbers at first but soon these active creatures start reproducing. Reproduction in cockroaches happens regularly and in huge clusters. The nymphs born out of eggs become adult German cockroaches in no time. Here, we have two repercussions. The food, which was already limited, is now being consumed by an elevated amount of cockroaches. This causes a problem as soon food is not as easily available as it was in the beginning. This realization causes these cockroaches to behave in an aggressive manner and soon they start attacking the sailors and other inhabitants of the ship. Cockroaches are known to be able to eat human nails, eyelashes and such superfluous outer parts. These bites look nominal and may cause irritation, swelling and lesions. Some people have reported to be suffering from minor infection causes.

How to treat German cockroach bites?

German cockroach bites are rare and look like small zits. But these bites should not be taken lightly. As soon as they are spotted, they should be treated. If you find a German cockroach bite on your body, dap it with lukewarm water. It is best to add some alkaline base in that water. Soap is the best alkaline base found easily at home substance. Rubbing alkaline substance on an acidic bite helps neutralize the wound.

If you see the bite swellings and filling with pus, it is highly recommended to immediately go see a doctor. Whenever a wound starts swelling and filling with pus, it indicates infection. It is best to take professional advice before the bite starts getting serious or out of hand.

How to recognize German cockroach invasion?

German cockroaches tend to be found in places where food is available quite easily. Houses, apartments, nursing homes, hostels, restaurants and hotels are some of the most likely places in the urban areas to find German cockroaches infestation. The first sign to look out for German cockroach infestation is droppings. German cockroach droppings are not as hard to recognize as they are to spot. The feces are small brownish in appearance. Many people have identified German cockroach poop as “pepper like objects”. As these creatures will be found where there is food, keep an eye out for the kitchen. Look in drawers and on top of countertops as well as on the edges of cupboards. If the German cockroach infestation is rich and populated, you can even detect a faint odor too.

How to prevent German cockroach infestation?

Escaping from bugs and house pests is completely impossible but this does not mean that you cannot reduce their invasion. You can prevent German cockroach infestation by following simple steps.

  • Make it a habit to keep your kitchen and pantry clean and hygienic.
  • Make sure to keep all the countertops clean and food free.
  • Wipe all the surface portions clean.
  • Make sure to store all the perishable items in the refrigerator.
  • Vacuum the entire surface available.
  • Make sure to keep the sink clean and avoid dishes from piling up and overflowing.
  • If you see any cockroach scuttling away, don’t take any chance and wait for a full blown infestation. Sprinkle some boric powder in all the suspected places. Boric powder is a household solution to prevent German cockroach infestation.


It is a common problem to have German cockroach infestation. Human beings have developed a variety of ways to counter this problem. There are home remedies and then there are professional chemical treatments like pest control to get rid of these vermin.

German Cockroaches Facts

I remember once a few years back, I went for a vacation with my family to Texas. We had rented a small villa. It was August and though it wasn’t full blown summer, it was still pretty hot. We were making a list of all the things we wanted to do and places we wanted to visit while in Texas. So, here’s the thing. Texas is a big place and it has literally different seasons and terrains. You have deserts, grasslands and prairies, a coast line and green wild jungles. We chose the desert side of Texas. We had some relatives who came over for a barbecue party on a Sunday. It was warm and sunny, and everyone was enjoying when suddenly my 10-year-old niece saw a cockroach and shrieked. We had invited some natives also who were seemingly unperturbed with the sighting of this particular vermin.

I found this interesting and being the curious soul that I am I asked them about cockroaches. Imagine visiting Texas, enjoying barbecued food and having a conversation about cockroaches instead of hot cowboys! But guess what? I actually learned a lot about these creatures. Let me impart some of my new-found knowledge with you guys.

  • Did you know that cockroaches are omnivores? Yes, cockroaches including Asian, American and German cockroaches are omnivores meaning they eat non – vegetarian as well as vegetarian food. They eat meat as well as plants.
  • German cockroaches can be found anywhere where there is dirt and filth. They can be found in garbage cans, in hotel and restaurants and in houses and apartments. They are known to be found in ships, especially cargo ships. Basically, what I am saying is that they can be found anywhere where food is easily available. It is a wonder they leave some places alone!
  • Did you know that German cockroaches can actually bite? I mean sure they do have teeth and they use them for eating but German cockroaches can actually bite you or any other thing when they get aggressive. Why do they get aggressive? Aggressive behavior is shown in these creatures when there is no food available easily. They usually settle at places where food is available easily but obviously food supply is not unlimited. When food starts becoming scarce, in a bout to survive they start displaying aggressive behavior.
  • Cockroaches have this amazing ability to actually live without their head for quite some time. Unlike human beings, cockroaches don’t breathe from their nostrils and, so they can afford to live without a head for at least a week. Even I want that superpower!
  • Ever wonder how so many cockroaches can infest an area so quickly? German cockroaches reproduce quite a lot and an average nymph is known to become an adult in under a month. That is some fast growing.
  • Cockroaches are really really fast runners. This makes it easy for them to transport from one place to another. It is an amazing athletic skill which makes it easy for them but tough for humans as they can as easily and quickly spread bacteria which cause diseases.
  • German cockroaches reproduce like crazy. I am not kidding when I say this statement. An average female German cockroach can reproduce hundreds and thousands of eggs which, in time, hatch and turn into nymphs. As stated earlier, nymphs turn into adult German cockroaches within a month or two, and that’s pretty fast.

Now that you know why there is such a huge population of German cockroaches, you will try to curb this always increasing rate by various methods. Pest control includes spraying of insecticides and other chemicals. Let me warn you before hand, if you think insecticide is the solution you are wrong. German cockroaches have been known to evolve continuously and they develop protection against specific insecticides. It’s like developing antibodies. This means that you will have to keep changing your insecticide and actually mix two or make a combination of insecticide to keep German cockroaches at bay if not kill them all.


Above stated are some interesting facts about these crawlers which can prove useful when you find a German cockroach infestation in your apartment or your surroundings. Keep them at bay and stay safe.

German Cockroach Eggs


The scientific name of a German cockroach is Blattella germanica (Linnaeus). All of us have an idea of how dangerous German cockroaches can be to your houses and families. The German cockroach egg can be equally devastating. They are usually found in clusters or colonies and infect the surfaces of your house. If you or the members of your family come in contact with those bacteria, you can fall sick. German cockroaches are never alone. Baby roaches are called nymphs and they take about two months to grow into full adults. Once they become adults, they start finding mates for themselves. It doesn’t take much time for them to find their partners. Impressive! right?

The real deal begins after the cockroaches have mated. After the mating process, the female cockroaches lay egg cases that are called Oothecae. The oothecae contain a large number of eggs that are wrapped in a layer of protein that, in the later stage, forms a hard and protective shell. Each egg case, that a female cockroach lays, contains around 50 eggs in it. Some species of cockroaches leave the egg case after laying it, whereas, other species carry the cases with them until they hatch. German cockroach eggs produce German cockroach babies that can be your worst nightmare ever.

A female German cockroach lays eggs in areas that are warm, moist and humid. Therefore, if you want to look for cockroaches, look in such areas. The egg shell or the capsule is pale in colour. The Female German cockroach can produce new egg shells every week if it breeds under favourable conditions. The life cycle of a German cockroach is continuous and goes on without a pause. This is another reason why one single cockroach can turn into a breeding machine and fill your house with German cockroaches if not taken care of.

The size of an egg case is 8 mm in length, 3 mm in height and 2 mm wide. It is brown in colour and looks like a small, purse-shaped capsule. Often, the eggs hatch from the Oothecae when the female cockroach is still carrying it in her genital chambers. It takes around 103 days for an egg to turn into an adult. In this article, we will talk about various aspects of a German cockroach’s egg, their gestation period and the stages of growth that it goes though.

Gestation period of a female German cockroach

Gestation period is the time span during which the child-bearer carries their young ones in their uterus. Insects do not have a well-build uterus, therefore, they are not said to be gestating. However, because the process is of giving birth, a lot of people term the development of the eggs in Cockroaches as “gestation”.

A female cockroach starts its gestation period when it creates Oothecae, that contains half a century of eggs. Maximum of the female cockroaches leave their Oothecae in a safe place so that they can hatch without any problems, but there are also female cockroaches that hatch their eggs while they are carrying it with them, or carry the egg case along until the egg hatches. Female German cockroaches are mostly seen doing this.

After the egg case hatches giving birth to nymphs, they are ghostly white in colour and soft in nature. They only get dark-skinned when their exoskeleton becomes hard and sturdy. The nymphs shed their exoskeletons 5-6 times before they become proper adults and go for mating. You can distinguish a baby cockroach from an adult cockroach by their size and many a times, their wings.

The nymph of a German cockroach

The life cycle of a German cockroach starts with it inside the egg case. The egg case breaks open due to all the nymphs pressurizing the shell. Once the egg case hatches, the baby of the cockroach is called a nymph. They are white in colour and they shed their skin multiple times while reaching adulthood. If the baby cockroach doesn’t get enough food in the first 12 hours after its birth, it can have problems in growing up into a proper adult.

The nymph of a German cockroach is pale brown in colour and every time it sheds its exoskeleton, it turns darker in colour. The development of a nymph to an adult takes about a year. The size of German cockroach nymphs when they hatch is about 3 mm long. After they darken their skin and colour, two stripes on their body occurs, stretching from their heads to their rears. The colour of these bands is usually dark brown or black.

The stages of a German cockroach’s life

A cockroach goes through egg and nymphal stage before turning into an adult. The number of Oothecae that a cockroach’s egg case carries depends solely on its species. The species of the female German cockroach carries around 50 nymphs in an egg case. Nymphs writhe and wriggle collectively inside the egg case to free themselves. The nymphs are similar to the adult German cockroaches in their looks and nature, the only exception being that they are smaller in size.

After undergoing a series of molts, the nymphs finally become adult cockroaches. There are a few species of cockroaches that also gain wings after their final molt. The average lifespan of a cockroach is around a year, but this factor also depends on the species of the cockroach. A lot of factors contribute to the lifespan of the German cockroach like temperature, environmental conditions, etc. Adult cockroaches are also called scavengers and they are known to be reproducing in large numbers.

German cockroaches, as a matter of fact all cockroaches, are nocturnal insects. They hide in closets and dark corners in the daytime and come out to look for food only in the night. That doesn’t mean that the tiny pests you spot in the daytime are not harmful. You should get rid of all of them.

How to get rid of German cockroach eggs?

German cockroaches lay eggs which turn into nymphs and then adults in no time. Therefore, it is very important to nip their breeding in the bud. If you ignore a baby cockroach, or a cockroach egg shell, assuming that it will do no harm, you are in for a huge surprise. These eggs hatch up to 50 nymphs at a time. Here are some ways to prevent the egg shells from hatching in your house.

  • Fill and fix the crevices and holes in your kitchen, bathrooms, and in and around closets.
  • When you bring in things from outside, inspect all your bags and plastics to see if there are any small cockroaches or egg shells attached to it.
  • After you work in the kitchen, or eat something, make sure you wipe up all the leftovers of food, crumbs and other particles clean. Otherwise, cockroaches will feed on them and survive peacefully in your house. This will also lead to them laying eggs more frequently.
  • After eating or cooking, do not keep the dishes and utensils in the sink for long. Wash them as soon as possible. If you keep them unattended, cockroaches will feed themselves and their colonies and breeding will increase.
  • Do not keep the trash of the bathroom or kitchen in the bin for a long time. Dirty places attract cockroaches and they tend to lay eggs on them. Therefore, dispose the daily trash to prevent the breeding of cockroach eggs.
  • You might find the shells of egg capsules and dead or alive baby roaches. Vacuum the house with a high-efficiency particular air vacuum cleaner filter. This will help to restrict the shell of cockroaches from being found here and there.
  • Do not keep cartons, newspaper stacks, and other dumping stuff in any corner of your house. These become places where cockroaches lay their egg shells. When you are placing clusters of boxes and newspapers in your house, keep them at a distance.

These were a few ways to get rid of German cockroach eggs. If you want to live in a cockroach-free house and environment, never forget to keep your surfaces clean and hygienic. Any dirt or leftover food can attract cockroaches and lead them to lay eggs and multiply in numbers.


The life cycle of a German cockroach egg is quite interesting, owing to the different challenges that if faces and overcomes in its lifespan.

Let’s see how dangerous these creatures are and whether we can kill them all or not in this article.

German Cockroaches biting Human Beings: Truth or False?

The first question that inevitably pops in your mind when I say that these cockroaches are dangerous is: Can German cockroaches bite human beings? We all know that most of the living beings are capable of biting other things deliberately. Be it human beings, snakes, birds, cattle or any other creature with teeth. Cockroaches are no exceptions; after all they do have teeth. But it is not very common when you hear that someone got bitten by a cockroach as opposed to someone got bitten by a dog. German cockroaches or Baby German cockroach can bite human beings but very rarely. Cockroaches by nature like dark places where they can hide and protect themselves. When a German cockroach actually bites someone, the bite is not like a gash. It looks more like a zit and can be treated at home.

How to treat a German cockroach bite at home?

I consider home remedies as best when dealing with insect bites. There is a basic formula to it. Insects usually have acidic bite which can be treated by applying something alkaline to it in order to neutralize the effect. I remember once I got bitten by a garden insect and there was some swelling. My mother immediately wiped the affected area with lukewarm water and applied soap on the wound. If you were an ace in Chemistry, you must remember that soap is alkaline in nature. This neutralizes the effect of the acid and relieves pain and burning if any.

Sometimes a German cockroach bite may swell up drastically. You can apply cold compress on the bite to relieve the swellings and numb the affected area. Applying a cold compress also relieves itchiness.

We all know that cockroaches thrive in filth. They call sewage and plumbing lines their home and these are the places where most of the diseases originate from. To make sure that the bite doesn’t give way to disease causing bacteria, you can rub a piece of onion on the bite.

If you are skeptical about using home remedies, the quickest way of treating and making sure that germs don’t enter your body via the bite, you can apply an antiseptic on the bite. Applying alcohol by dabbing cotton on the bite ensures no germs can enter through the bite and into your body.

One is suggested to be careful with the bite and not to take it lightly. If there is more swelling even after treating the wound and any indication of pus filling up inside, you should opt for professional doctor’s advice as these symptoms indicate that the wound has become infected.

What can we do to prevent German cockroach infestation in our homes?

German cockroaches can easily infest our living area. Instead of just being an irritating nuisance they are dangerous to our health. German cockroaches can reproduce really quickly.

When you spot a German cockroach baby in your house, do not make the mistake of ignoring it or pitying it in any way. Identify these small pests first, and immediately get rid of them.

What do the babies look like?

Cockroaches are our worst fear and nightmare, and you simply have to reduce it to the size of a small ladybug. Did you imagine it? Yes, that is a German cockroach baby – oval-shaped, dark brown in colour and walking on six legs. The babies of German cockroaches are usually brown in colour, light brown, medium brown, or dark brown. But don’t spare a baby cockroach if it’s white in colour, because that is what they look like immediately after they have molted.

German cockroach babies have long antennae even though they are so small. Their antennae are longer in length than their bodies. The babies also possess sensory appendages that they carry throughout their lives, and these are called “cerci”. A special feature of these cockroach babies are the two stripes that they carry. These stripes are black and they run from their heads to their rears. You might not be able to see these stripes with the naked eye because they are very small, but they are present. If you desperately want to see these stripes, you can try using a magnifying glass.

What is the size of these babies?

German Cockroach Baby

When German cockroaches are babies, they are extremely tiny, and look like baby beetles. If you look at American species of cockroaches and their babies, they are comparatively larger than the German species. German cockroach baby is equal to, and many times even smaller, a rice grain when they are born. They can be compared to the size of small ants.

How small cockroaches become big adult problems?

Nymph is the word that we use for baby cockroaches from their birth to them reaching their adulthood. During this nymphal stage, the baby cockroach sheds its exoskeleton multiple times. Every time they shed their exoskeleton, they grow a new one that is larger than the last one. This process is called molting. German cockroach baby sheds its exoskeleton around 5-6 times within a span of 1.5-2 months. Small cockroaches keep gulping in air till their body expands and breaks their exoskeleton.

When the German cockroach baby becomes an adult, it starts finding a mate for itself. When they find a mate within a few days of becoming an adult, they start producing babies without wasting any time.

How are German cockroach babies hazardous to our health?

You must have never heard about a cockroach biting or stinging someone, have you? In that case, how are they even dangerous to our homes and people?

German cockroach baby carries a lot of dirt and bacteria with them at all times because of the places that they roam about in. They are always found in dirty places like gutters, dumpsters, dustbins, pipes, etc. They carry bacteria from all these places, and when they enter your rooms and kitchen, they spread these bacteria all around. These bacteria can harm people if they are present on cooking surfaces, utensils, inside food and spice containers, and any other place which is connected to people’s hands or stomachs.

Many of you might ignore a single baby cockroach believing that it isn’t that harmful, but let us tell you that cockroaches are rarely alone. They always live is clusters and if you spot one in your house, know that there is an army hiding somewhere too.

What does the presence of German cockroach babies mean?

Although babies are supposed to be cute, baby cockroaches are an exception. There are various species of cockroaches all around the world, and German cockroaches are believed to be the most mischievous and harmful ones. Therefore, even if you spot a nymph in your house, don’t sit still. Get rid of it immediately! Why you ask? Because nymphs do not take much time to gain adulthood and as soon as they hit adulthood, they reproduce in huge numbers throughout the year.

A single egg capsule that a female German cockroach lays has 50 eggs! Yes, you read it right. When these eggs hatch and nymphs appear, they are ready to take care of themselves and feed their own stomachs. This means that a colony of a few cockroaches can turn to hundreds of them in just a few months.

Nymphs usually do not go far away from their nests. Therefore, if a nymph is leading a good life, it means that the parents have made their nest in a place where there is easy access to food and it is safe to lay eggs.

What do German cockroaches get attracted to?

If you have places in your house that are usually wet and damp, look for German cockroaches there. The colonies of the German cockroaches are usually found in dark and damp places of the house, like the basement, attic, closet, kitchen, etc. Any place that has moisture will have a colony of German cockroaches too.

You should take special care in kitchens and bathrooms as they are mostly found in these two places of the house. You will not see them during the morning because they hide in cupboards, holes and crevices of your house. As soon as night falls, they come out in large numbers, and search the kitchen and other areas for food, and in this process, spread the dirt and bacteria too.

How will you identify German cockroach infestation?

A lot of times we don’t actually see the German cockroach baby, but they have still taken over your kitchens and bathrooms without you even knowing. There are a few other ways of knowing whether the nymphs have attacked your house or decided to spare you after all.

  • Look for cockroach poop
  • If you get a stale odor in your house, you have been attacked
  • Cases of cockroach egg, or the molted exoskeleton
  • Dead bodies of cockroaches

If you find any of the above in your house, make sure you find a way to get rid of those roaches as soon as possible. Cockroach excreta looks like a collection of tiny black specks that you can find in the corners of cabinets or on the floor. It looks very similar to coffee powder, but you can recognize it from its stale smell. This smell will linger on the surfaces and even on the food that has come in contact with them.

If you want to identify cockroach’s egg, look for small capsule like shells. They are dark brown in colour and are a signal that cockroaches are breeding in your house. You might also spot dead cockroaches in your house which gives you a reason to be happy, but also remember that this makes space for more cockroaches.

What to infer when you find nymphs in your house?

Finding baby roaches in your house is not a good sign at all. If you spot an adult cockroach, you might be lucky and that cockroach hasn’t found its mate yet. Getting rid of that cockroach might be the end of your problems, but if you spot a nymph in your house, the possibility of a cluster of them hiding somewhere is very high, and that is a matter of tension. The babies will take less than two months to grow into adults and start reproducing regularly, making your life worse than it already is.

Therefore, as soon as you spot a baby cockroach, act fast. Don’t give them the opportunity to start their families in your house.

How will you get rid of baby cockroaches?

And the bad news is that they are they are really difficult to get rid of. Homeowners and pest controllers dislike them for this very reason. Once you feel that you have gotten victory over them, a baby cockroach might emerge out of nowhere and join your victory dance. That is because they do not take much time to grow and produce half a century of babies each time. The German cockroaches do not require a lot of food or moisture to survive. A little is enough for them, and that is why most homes are at a risk of getting attacked by them.

Now, how do we actually get rid of the German cockroach baby?

There are a lot of DIY ideas to control cockroaches in your houses that can eradicate infestations for good. But, before you try any of these methods, you should try using pesticides, as it is the most effective way to get rid of German cockroaches. You can either choose baits or sprays, but these are designed to kill cockroaches individually. You can add insect growth regulator that will make the cockroaches infertile, restricting their growth. You can then aim at one colony at a time and end them completely.

Baits are believed to be one of the most effective ways to get rid of German cockroaches breeding in your house. They work as fast as other sprays and spread their ingredient from one cockroach to the other, spreading it among the entire colony. Even if you are dealing with German cockroach baby, you need to use effective measures like sticky cockroach traps that you can control the size of their clusters and attack them easily.

You should use baits in concentrated amount and in particular places where you think the German cockroaches usually walk. Place them in areas where you think the roaches go to for food and water. You can also use natural cockroach killers to increase the effectiveness of your extermination.

How to keep German cockroaches away after having exterminated them?

If you have had an experience of getting rid of baby German cockroaches, you will never want to do it again. You can regularly clean the damp spaces of your house, seal and repair crevices so that they don’t breed inside them. You can use essential oils with a pleasant smell that will keep them away. Also, make sure you spray pesticides on a regular basis in your house in the future.


Dangerous things do not always come in large sizes, and German cockroach baby has proved it well. These insects are not worthy of residing in your houses, as all they do is make you and your family sick. You should not ignore even the smallest German cockroach as they might be a signal of a larger infestation. Therefore, we provided you a detailed guide about how you can identify a German cockroach and get rid of them for once and for all.

We hope this article has given you everything you and your family need to lead a cockroach-free life now and forever.

German Cockroach

German Cockroach appeared on earth way before humans or any other current organism did, more than 300 million years ago, even though the present-day cockroaches that we come across today have evolved with time and differ from their ancestors in several terms. Though small, they are still, one of the most populous organisms and can be found across the globe. Ranging from different sizes and different colors they are spread around the world in all kinds of ‘nests’ where to keep existing even today. Forests, to industrial cities and towns; all have at least one or the other kind of cockroach inhabiting their trees and lanes and pipelines.

Like any other line of organisms, they have different kinds of lineage dividing the larger order Blattodea into smaller families and species. Quite interestingly, termites while belonging to this order, run parallel to the cockroach variety and were previously considered very different from them.

There are a little less than 4700 species of cockroach known yet, out of which 28 to 31 are found in surrounding man and very few are established as pests.

German cockroaches are unique in the sense that they probably grow the fastest, each adult reproducing generations of nymphs, and eventually adults, that continue the cycle and populate their area of ingestion quite densely.

The scientific association of the German Cockroach:

The German Cockroach belongs to the genus Blattella and species germanica that and hence is scientifically known as Blattella germanica.

It comes from the superorder Dictyoptera and more specifically the Ectobiidea family.

They are Arthropods, because of the presence of an outer harder and solid skeleton-like structure that gives shape to their body, which is divided into segments, belonging to the phylum Insecta and runs parallel to the order belonging to other insects like a mantis.

While other insects like butterflies and moths too belong to the same phylum, cockroaches differ from them point down which is categorized as one goes down the scientific nomenclature system classifying the organism into its specific and objective category.

What does a German Cockroach look like?

A German Cockroach is considerably small in size when compared to its other variants. The dimensions of an adult German Cockroach are about 1.2cm to 1.7cm approximately or 0.42 inches to 0.61 inches approximately.

They are burnt brownish to a very deep brown that often seems black. However, the characteristic feature of this type of cockroach is the dual lines running from their head right to the base of their wings which is the spot from where the structure for their wings begins.

German cockroaches may have wings. However, unlike their other varieties, for example, the American Cockroach, they cannot fly. Though they have been seen to be doing a pseudo-flight movement, however, they can hover around but not fly completely.

This type of cockroach can be easily confused with the Asian Cockroach because of its size and color. However, one needs to look closely to distinguish between the two by the dark lines running on their anterior section of the head.

The male and female German Cockroach can also be distinguished. The male German Cockroach is slender and not exactly thick, with a sharp body and its segmented posterior section visible. When looked at from a distance, the name seems a little lighter in color than the female probably due to the structure of the density of the wing and abdomen. The female is rounder to look at, with a denser color around the abdomen and is more stalky than sleek. It has tegmina, the leathery wing which covers most of its body, and hence its segmented structure is usually not visible.

Where did the German Cockroach originate?

As the name itself suggests, it was thought to have belonged to European countries. However, its origin was later tracked down to other locations after considering other factors and characteristics it exhibits even today. People believed that the German Cockroach might have originated from parts of North-East African nations. However, it was later confirmed that this variant was in fact, first found in countries like now Thailand, in South-East Asian nations.

This confusion over their origin in ‘Germany’ or any other European nation was because these cockroaches can hardly tolerate lower temperatures and thus might have originated somewhere warm and damp, like their habitat preference till today. This is also a viable reason that explains their absence in the polar regions which are extremely cold with little to no food supply and other remote yet big lands detached from the rest of the larger pieces of landmasses that are otherwise interconnected. While the cause for their situation to warmer climates can be understood, the spread across the globe probably traveled across the seas in larger carriers like ships.

Where can the German Cockroach be found?

The German Cockroach can be found in warm and damp habitats and are most common in residential apartments and blocks, all sorts of kitchens be it domestic or commercial, other organizational buildings that are inhabited by humans. This is because any human habitations are usually warm and suit the German Cockroaches requirements better to build a nest and procreate. Since they are small, they tend to inhabit the cracks and spaces between furniture surfaces in warm places like the kitchen which serves to be the best location in terms of their temperature requirements and food availability. One can find a German Cockroach in a dark nook between items of furniture and the walls or in the deep dark crack of some surface, with their body inside and antenna outside, sensing any kind of movement that could be a potential danger to them, upon sensing which they immediately shutter deep inside their habitat. When frightened or caught by surprise, German Cockroaches tend to release a stench that acts as signifiers for their existence.

While they are nocturnal, and hence should stay inside during the day, they are often spotted even during the day time in the kitchen or other warm places of the house or building, especially if a light is suddenly flashed in a dark room.

German cockroaches have a strong affinity towards warm and damp places since they cannot tolerate cold temperatures. This is one of the most important criteria for them choosing to build their nests in human-inhabited buildings or other kinds of places where there is human interaction since it provides them with the warm atmosphere they require. The temperature range that a German Cockroach finds most suitable is around 60°F to 97°F which is about 16°C to 37°C. Any lower than the given temperature ranges they become unable to move and hence feed and if too cold, they cannot survive. They are most common in kitchens and food industries and factories which are heated and can be a source of food scrap for them to feed on.

If a building or house is uninhabited by humans for a long time, leaving the place cold and empty, these cockroaches tend to move away to more suitable locations.

What does a German Cockroach feed on?

A typical German Cockroach feeds on scraps of chicken, mutton, fish or any other meat available, food fats, sweet items, starch products like rice grains and in the absence of these, can switch to domestic everyday items like glue and book bindings, detergent, paste among other things. Surprisingly, if need be, a typical German Cockroach can change its food habits to become cannibalistic and feed on each other if there is an acute shortage of food and resources.

The lifecycle of a German Cockroach:

The lifecycle of a German Cockroach is like that of any other variant of cockroach, or insect in general which involves an egg stage, a nymph stage, and finally an adult stage.

During the egg stage, the mother cockroach carries the eggs in a pouch that remains attached to its body. Once the eggs are hatched, the nymphs start appearing and go through a period of transition that involves them shedding their cover and after multiple religions of this stage of coming out of their shell, they turn into adults. It takes about one and a half months to two whole months for a nymph to go through its mounting stages and turn into a mature adult. The adults then, further give birth to a new generation of nymphs, and the process repeats. The average time for which a German Cockroach lives and completes its life cycle is usually about 120 days, although a large part of it varies with the availability of food sources, shelter, and temperature conditions.

Reproductive Cycle of the German Cockroach:

It is to be noted that the reproductive cycle of the German Cockroach is very short and takes place very quickly, allowing each adult female to reproduce very fast and hence create a larger population of multiple generations very fast. Cockroaches release a sex pheromone which is known as Blattellaquinone that attracts a male cockroach towards the adult female.

The reproductive cycle starts once the female is fertilized and starts producing a pouch that is rectangular with rounded edges and about a quarter of an inch in size with ridges or segmented lines running across. This pouch is known as the Ootheca and holds the eggs (about 35 approximately) inside it and causes the body of the cockroach to seem fuller in size. As the pouch starts coming out of the posterior side of the adult female German Cockroach, it changes its color from pale to light red and funnily a deep reddish-brown. The eggs, which are usually fully developed, sometimes hatch out even while the pouch is attached to the female body. However, the rest of the nymphs are born only after the pouch drops off. The size of the nymphs is usually 2.9 mm although more than 50% of the nymphs die. An average German Cockroach usually undergoes rounds of ecdysis, the phase between each round known as an instar. It can be claimed that many nymphs never get past the instar phases.

Considering the rapid growth in their numbers once they turn into adults, it can be considered as a natural elimination or controlling process to keep their numbers at bay.

These nymphs usually have a deep-brownish tinge and lack wings, although they have chemoreceptors that enable them to sense any signs of chemical presence from a distance and hence are usually very difficult to poison with insecticides.

Pest control measures for German Cockroach :

German cockroaches can be considered kings among household pests because of their high rates of reproduction which often allows multiple generations to exist at the same time in the same location, infesting whole buildings at times. This can be supported by the fact that buildings infected by these pests have found hundreds and thousands of these pests in numbers, creating nests in hollow spaces across different areas of the building.

The presence of German Cockroaches is highly unhygienic because of the diseases and illnesses that they spread. As pests, they often play host-organism to other bacteria and viruses which can then spread through the food or items they excrete on. Their presence, while pointing towards unhygienic living conditions also indicate possible illnesses and problems that can spread among the people inhabiting such surroundings. The factors that render them a difficult variety to control are because of their small and unreachable nests, extremely vigorous reproductive cycle, the absence of any higher organism preying on them, and most importantly the ability to sense chemicals. German Cockroaches live in small cracks and corners and hence can be found in large numbers if one is found and the rest are searched properly.

Insecticides drive them away from specific locations although they can return to the treated surface once the effect of the chemical is gone. This suits them perfectly since they can sense chemicals and can afford to stay away from spaces that they sense have been sprayed with chemical compounds. On the other hand, since they inhabit small spaces, locating and eradicating all together is easier if their nest is found.

A common procedure of using glucose as bait for pests do not work on these cockroaches since they stay away from them, with time and adaptation. On the other hand, their reproduction rates are quickened if they manage to keep their temptation at bay, almost as a reward. Hence, the use of pest bait is also usually useless when it comes to these organisms.

The only option is to spray entire apartments, including the drains and pipelines along with all cracks, nooks, and crannies and the base of floorboards and other hollow surfaces through the building, where even one apartment is infected. This is because the German Cockroach tends to change its habitat now and then, and if it finds a location heavy with chemicals it moves to someplace nearby that is free of these toxins. After a while, they can move back to their previous habitat once the effect of the toxin is lost.

Pest glue traps can also be used to trap pests. However, the best way is to seal all gaps and hollow spaces, and regularly move items of furniture to clean spaces and keep a place neat and tidy. Also, periodic pest control checks and services are equally essential to keep these insects at bay.
