Red cockroach

Red cockroach. The lifestyle and habitat of the red cockroach

There is probably no such person who does not know who he is red cockroach. Not necessarily familiarity with this insect should happen at home. Red cockroach Prusak can meet in any institution.

You can stumble upon it at school, in a store, in the dining room, in the hospital, or even just outside. This slender and unpleasant mustachioed creature is quite nimble and always trying to quickly hide in the most secluded places.

But, despite the fact that this insect accompanies a person almost everywhere and everywhere, people know amazingly little about it. And, by the way, big red cockroaches are very, very amazing neighbors. Why dream of red cockroaches? This is a very good symbol, which portends the improvement of life, financial situation in the family.

Features and habitat of the red cockroach

Ginger cockroach — this is a typical representative of a large suborder of the cockroach family. All representatives of this genus have striking similarities in appearance and behavior.

Due to its wide popularity, the red cockroach has many different names. Even if you do not take into account all the popular names of this creature, its names in different countries can be counted about 20.

Its most common name in Russia is Prusak. From this word, the conclusion suggests itself that this insect for the Russians is somehow connected with Germany.

In fact, it is, because the time of the most terrible invasion of Russia by this annoying insect coincided with the arrival of Napoleon’s army. Therefore, many are inclined to assume that it was from Prussia that cockroaches arrived in Russia. An interesting fact is that in Germany cockroaches are called Russians and they say that it was from Russia that they entered this country.

The structure of the red cockroach basically the same for his entire suborder. Judging by photo of a red cockroach its main organs are the cephalothorax, head, abdomen, paws and wings. When viewed from above, only one head is visible. The rest of the body is well covered by wings. Speaking of wings. In fact, a cockroach cannot fly.

Wings were given to him in order to reduce the speed a little during the fall, and, accordingly, to provide the insect with a normal and safe fall. There is, of course, an exception among them — flying cockroaches.

If we already started talking about the individual characteristics of a red cockroach, then it is worth noting that it is very resistant to radiation and is one of the very first candidates for life during a possible nuclear attack.

One of the main organs of this insect is its antennae. With their help, he not only distinguishes certain smells, but also communicates with representatives of other individuals. He takes great care of his body and constantly cleans the antennae. If suddenly for some reason the cockroach has lost, at least one antennae, it instantly loses half of the information about its environment.

You can distinguish a female cockroach from a male. It is slightly larger and has a slightly shorter abdomen. In its structure, the red cockroach is similar to mantis and termites. But, despite the fact that in their structure much in common with the mantis, the desire to feast on the so-called neighbor of the systematic ladder will never disappear.

An adult red cockroach reaches a small size — 1-1.5 cm. If you compare it with other relatives, then it is one of its smallest representatives.

Their individual feature is minor outgrowths at the end of the body. They are called tserki and are a sign of primitiveness, which only ancient insects differ in.

Often red cockroaches live in the countries of Central Asia, for them there are the most optimal natural conditions of existence. But in the premises you can meet him literally everywhere except the cold latitudes of Antarctica.

This is a widespread insect, which is much more comfortable in a living room than in nature. Therefore, the territory of their distribution is becoming wider and wider. They quickly capture cities, towns and villages and are firmly settled in the neighborhood with man.

The nature and lifestyle of a red cockroach

In fact, the Prussians are completely defenseless against their detractors. The only thing that can save their lives is a quick run. Thus, they can escape from their enemies and hide in any shelter. In these shelters, cockroaches prefer to stay all daylight hours and only in the dark to leave it in search of food.

For the normal existence of the Prussians do not need smart conditions. They have enough average air temperature, access to food and water. A temperature of -5 threatens death for these insects; they cannot tolerate lowering temperatures to such an extent.

Therefore, in camps where severe winters exist, the Prussians live only in residential premises. Red cockroaches in the apartment They settle mainly in the kitchen or in the closet, where you can get food without problems. They lead a hidden lifestyle. Slots are considered to be the most ideal place for them, in which the cockroach can feel the “floor” and “ceiling”.

Types of red cockroaches

Cockroaches prefer to live in comfortable, but not perfectly cleaned rooms. It is such an environment that is most suitable for their good existence. Each country is characterized by certain types of red cockroaches.

There are the most common ones. Many years ago, few people paid attention to their neighborhood in the huts. But recently, for about 50 years, people have been waging the most fierce struggle with them.

The status of domestic insects has stuck to many species of cockroaches. But most of them still live in natural conditions. Scientists have counted about 4600 species of cockroaches, which can be seen in almost all corners of the earth.

Of these, the most popular are black cockroaches, red and American. By their structure, black cockroaches slightly resemble the red-headed Prusak known to us. But they are larger. The length of the adult female is about 4 cm, and the male 3 cm.

Their glands secrete a very unpleasant odor, which is what distinguishes this particular type of cockroach. The American cockroach with its color strongly resembles a Prusaka. But differs from it in a narrow and oblong shape, as well as in size.

American cockroach is much larger than red. It is known that black and red cockroaches cannot get along with an overseas fellow, because the latter eats them.

Red Cockroach Eating

These insects feed on what people cannot even suspect. A small piece of glue on the wallpaper or in the binding of a book can last for a long time. Food waste in the bin is simply royal food for them. Unobtrusive crumbs under the table, refrigerator or in the closet are for them a favorite product that they can eat endlessly.

They just need water. An apartment or house with ever-flowing communications is the favorite place of these insects. Even if they are not yet in such a room, they will not take long to wait. Trays for flowers, in which water is always present, are also a source of moisture for them.

Reproduction and life expectancy of a red cockroach

Prussians belong to insects with an incomplete development cycle. Its stages of reproduction and development consist of several stages. An adult female who is already ready to bear fruit lays about forty eggs in a special capsule.

Red cockroach larva

This capsule is constantly located on her abdomen. You can notice it with the naked eye. The development of eggs in this capsule lasts from a week to a month. It all depends on the environment and the living conditions of the female.

After this time, the female dumps this load from herself and the nymphs leave the compartments. These small insects differ from the large red-headed Prusaks in their dark color and lack of wings.

Little Prussians eat the same food as adults and after 60 days they can not be distinguished. Cockroaches live for about 30 weeks. It is known that one female is able to bear about 300 cockroaches in her entire short life, which in two months are also ready for childbirth.

How to get rid of red cockroaches

There are people who do not know about the danger that the proximity to the Prussians poses. In fact, this insect easily tolerates such terrible diseases as hepatitis, tuberculosis, tetanus, dysentery and salmonellosis.

On its legs you can find a variety of pathogenic microorganisms that cause infectious diseases. These spores, fungi and all other evil spirits fall from the legs of the Prusaks to improperly stored food, and from there into the human body. In addition, they carry helminths, pinworms and whipworms. They can also cause allergies in people.

As soon as at least one Prusak was seen in the house, it was necessary not to pull, but to urgently take action. Two weeks is enough for the hordes of these insects to appear in the apartment. Many people ask the question how to get rid of red cockroaches as soon as possible. To do this, first of all:

  • Deal with food. They should be in special containers or tight bags.
  • Check that there are no dirty dishes or food debris in the sink.
  • Try to maintain perfect cleanliness especially in the kitchen and in the bathroom.
  • Throw garbage more often.
  • Repair all water leakage in the pipes.
  • Take care that there is nowhere water that is so necessary for red cockroaches.

As soon as all these points are observed, you can proceed to the main task of combating the Prussians — their persecution. There is not one effective remedies for red cockroaches.

  1. You can use boric acid powder, which must be mixed in mashed potatoes, made balls from it and put in the most favorite places of the Prussians. Boric acid dehydrates these insects.
  2. The self-made trap method is well established. Everything is very simple. It is necessary to put the bait for the Prussians at the bottom of the can, and grease its rim with a greasy, sticky substance. It can be petroleum jelly or regular oil.

In order for the cockroaches to leave and not return, the fight against them must be waged together with all neighbors, otherwise it can go on forever.

Cockroaches: Ecology, Behavior, and Natural History. William J. Bell, Louis M. Roth, and Christine A. Nalepa.

Srini Kambhampati, Cockroaches: Ecology, Behavior, and Natural History. William J. Bell, Louis M. Roth, and Christine A. Nalepa., Integrative and Comparative Biology, Volume 48, Issue 4, October 2008, Pages 541–543, https://doi.org/10.1093/icb/icn074

Mention cockroaches and there is a near universal negative reaction, usually associated with unhygienic conditions, disease, and general disgust. This is understandable because most people (including many biologists who do not study cockroaches) are generally familiar with just a handful of “pest” cockroach species that have become associated with human habitation. Few people realize the extent of cockroach diversity in life history, habitat, behavior, and morphology. Few books exist on the ecology, life history, and biology of cockroaches other than those that are closely associated with humans. This book attempts to summarize the large amount of information that has accumulated in disparate scientific journals on a wide variety of cockroach species. The emphasis of the book in general is on the less familiar species, many of which live in forests, and therefore, are rarely encountered by humans.

The book consists of 10 chapters and begins with a general description of cockroach morphology. Although cockroaches vary widely in their physical appearance, they share a number of morphological features in common. A number of fascinating features have evolved over the millennia: horn-like protrusions on the pronotum, exquisite mimicry of a variety of beetle species, bright coloration, and sexual dimorphism. The second chapter deals with locomotion. Cockroaches, especially the peridomestic species, are best known for their fast running. However, there is a great deal of variability in cockroach locomotion including swimming and flying. Although many cockroach species are wingless, some species are strong fliers and sexual dimorphism in presence/absence of wings is not uncommon. This chapter includes detailed information on the ecological correlates of wing condition, life history trade-offs, population structure, correlation between wings and habitat, as well as other evolutionary aspects.

Cockroaches occupy a wide variety of habitats (Chapter 3) including tropical and temperate forests, deserts, grasslands, and salt marshes. Similarly, they have a wide vertical distribution ranging from tropical rain forest canopies to deep in the soil. The broad habitat is reflected in a number of features such as diet and foraging (Chapter 4), morphology, physiology, reproduction, diet, circadian rhythms, and seasonal activity.

One of the more fascinating aspects of cockroach biology is their association with microbial symbionts (Chapter 5). Cockroaches harbor a wide variety of symbionts in their gut as well as fat bodies. It is widely believed that the association with microbes has played a large role in the adaptation and evolution of cockroaches, as it has in many other organisms. The hindguts of all cockroaches that have been examined harbor a wide variety of microbes, including ciliates, amoebae, flagellates, and various prokaryotes. These are believed to play a major role in digestion. With the exception of one genus (Nocticola) all cockroaches examined to date also harbor endosymbiotic bacteria in the genus Blattabacterium, which are believed to have an essential role in uric acid metabolism. In addition, some cockroaches (e.g., Cryptocercus) also harbor specialized microbes such as those involved in the breakdown of lignocellulose.

Cockroaches exhibit a wide variety of fascinating mating strategies and behaviors (Chapter 6), although only a few species have been studied in detail. Like most other insects, cockroaches communicate using chemicals; however, a number of other signals such as visual, tactile, and acoustic may be involved in courtship and mate finding.

Chapter 7 is a detailed description of the wide variety of reproductive strategies exhibited by cockroaches. Cockroaches produce and deposit oothecae, which are egg cases containing multiple embryos. Cockroaches also exhibit a range of reproductive modes, including oviparity ovoviviparity, viviparity, and parthenogenesis.

Another fascinating aspect of cockroach biology is their social behavior (Chapter 8). A majority of cockroach species are solitary; however, a number of them are gregarious or subsocial. It is widely believed that eusocial termites evolved from subsocial cockroaches (Chapter 9), a finding that is important to the understanding of termite evolution. Parental care is also often exhibited by cockroaches and is reflected to some extent by ovoviviparity and viviparity. Chapter 9 examines the similarities between termites and cockroaches and attempts to make the case that the former evolved from the latter.

The final chapter is an examination of the ecological impact of cockroaches. This is perhaps one of the more under-investigated aspects of cockroaches. Cockroaches are an important source of food for a number of organisms, including arthropods, birds, and mammals. As such, they are an important part of the food chain. Cockroaches also play an extremely important role in nutrient cycling. A majority of cockroaches are detritus feeders and with the help of endogenous cellulases play an important role in degrading plant material. Some species, such as Cryptocercus, feed directly on wood and play a major role in lignocellulose digestion in temperate forests. This book concludes with an appendix of taxonomic designations of genera discussed in the book and a glossary of terms.

Overall, this is a well-written book that is also visually attractive. The figures (line drawings and black and white photographs) are clear and relevant. It is indeed tragic that two of the authors and foremost experts on cockroaches (Roth and Bell) passed away before the completion of the book and did not have an opportunity to see the end product. This book is much needed to educate biologists about the fascinating biology and diversity of cockroaches. It is perhaps a little too technical for the general public, but anyone with a background in science is likely to comprehend most of the information here. My one criticism is that a number of recent and relevant references have been left out. Beyond that I think this book should be read by anyone interested in cockroach diversity and evolution. I especially recommend this book to graduate students so they can perhaps realize the myriad opportunities and unanswered questions that exist in the study of cockroach biology and evolution.

A Female Cockroach Can Lay Up to 90 Eggs at One Time

There is a reason why they say if you see one cockroach, there must be another hundred of them! One of the basic cockroach facts is that this insect can reproduce super fast. On average, a female cockroach will lay between 10 and 90 eggs at one time. The eggs hatch within days and the baby cockroaches will become fully grown within a month. Each female cockroach can lay eggs up to four times a year. At this rate, given a good habitat, cockroaches can multiply pretty quickly!

There Are Roaches on Every Continent

Cockroaches are probably one of the most adaptable species on Earth. They can live in a wide range of climates and environmental conditions. There are different types of roaches on every continent on Earth. In total, 4,600 species of cockroaches have been identified. Thankfully, for those who aren’t fans of cockroaches, only 30 of these species share human habitats. Of these 30 species, there are four common types that you are most likely to run into: the American cockroach, the German cockroach, the Australian cockroach and the Oriental cockroach.

Cockroaches Are as Old as Dinosaurs

Because of their incredible adaptability, cockroaches have survived the many harsh periods of environmental change on Earth. The oldest roach fossils ever found date back as far as 350 million years ago. This means that cockroaches are as old as dinosaurs. While dinosaurs are extinct now, cockroaches are still surviving well, and have experienced few changes to their genetics over the years. The study of fossils suggests that the modern cockroach is smaller than its ancestors, however. Back in the time of dinosaurs, cockroaches could be as big as 20 inches long. But otherwise, there has been little change in their appearance.

Cockroaches Can Eat Anything

There are many cockroach facts that explain this creature’s amazing survival skills. Cockroaches have survived for as long as they have partly because of their varied diet. As omnivores, they like to eat everything, including meats, starches, sweets and decaying matter. In fact, wild cockroaches are important to the ecosystem because they digest decaying wood and other organic waste. In a way, the cockroach plays the role of cleaner in the wild. Cockroaches that live near humans, however, do not have such a clean reputation. They eat pretty much anything, including our food, dead skin cells, hair, garbage and even faeces.

A Cockroach Has 18 Knees

The anatomy of a cockroach can be quite interesting and reveals many fun cockroach facts. A typical cockroach has 6 legs and a total of 18 knees. Why so many knees? This is because, with multiple joints, cockroach legs can adapt to many different terrains. This is why they can move very fast when running away from predators. Another fun fact about cockroach legs is that they have tiny hairs that can detect movements of air. This helps the roach stay alert to any potential threat and makes it very hard to catch.

Cockroaches Can Survive a Month without Food

Cockroaches are surprisingly good dieters who can survive a whole month without food. This is because they are a cold-blooded species. A cockroach needs much less food than a human does in order to survive. Research shows that cockroaches kept in a sealed jar without any food can last a whole month. Cockroaches need access to water, however. Without any water to drink, they will die within just one week. This is why cockroaches are often found near water sources, such as kitchens.

Cockroaches can go without Breathing for up to 40 Minutes

Not only are they able to survive for long periods without food, but cockroaches can also go without air for much longer than you might expect! Studies show that certain types of roaches can go as long as 40 minutes without breathing. Because of this fact, they also make excellent divers. Cockroaches can survive under water for up to 30 minutes. The reason why cockroaches can hold their breath for so long is because they may need to do so to regulate water loss. They use the same tube to breathe and to transport water vapour out. When roaches need to retain water in their body, they shut this tube, and therefore, need to stop breathing.

Cockroaches Spread 33 Different Kinds of Bacteria

Most people don’t like cockroaches and associate them with dirty places, and that is for a good reason. Cockroaches can spread up to 33 different kinds of bacteria. Among these are salmonella and E.coli, which can cause severe food poisoning or gastroenteritis. Cockroaches shed their skins from time to time, and the dead skin can carry bacteria and contaminate human food. The skin and cockroach droppings can also cause allergic reactions and other illnesses. Cockroach allergy is also known to trigger severe reactions among people with asthma.

Cockroaches Spend a Lot of Time Resting

Cockroaches can move quite quickly when necessary, and can run as fast as three miles per hour. Even a one-day-old baby roach can run almost as fast as a grown-up one. However, roaches only move quickly when they detect danger. The rest of the time, they are not as energetic as you might imagine. A cockroach spends approximately three-quarters of its time just resting in one spot. Roaches that live near humans spend most of their time hiding in dark, secluded places. They can happily survive in just a few inches of space.

Cockroaches Have Wings, But Most Cannot Fly

Cockroach facts suggest that roaches rely on their feet more than their wings when trying to get away from predators. Although many species have wings, most cockroaches can only fly over a short distance. Some species of cockroaches cannot fly at all. American cockroaches, for example, only use their wings to glide from a high spot to a lower surface. The wings of the roaches are often quite tough and sturdy, so they also act as a shield. But the tough wings, coupled with a relatively heavy body mass, make it difficult for roaches to fly efficiently.

Cockroaches Have a Taste for Beer

There is one thing that cockroaches may have in common with their human housemates: they are attracted to alcoholic beverages, especially beer. This does not mean that you will ever find a thriving party where cockroaches drink to enjoy themselves. Studies show that roaches are more likely to be attracted to the mixture of hops and sugars. This is one of the cockroach facts that prove helpful for pest control. Many people successfully create a homemade cockroach trap with just leftover beer, a bottle or a jar, and some cooking oil.

A Cockroach Can Live without Its Head for up To 2 Weeks

One of the creepiest cockroach facts is that a cockroach can roam around headless for up to 2 weeks. This is because, unlike other insects and animals, the brain of a cockroach is located inside its body instead of its head. When the head is cut off, the brain is still intact and can continue to control the rest of the body.

Cockroaches also breathe through little holes throughout the body, so the head is not needed for breathing purposes. Also, cockroaches do not have blood pressure and an open circulatory system like we do. When the head is cut off, the bleeding will simply stop because of clotting at the cut. Eventually, after two weeks or so without its head, the cockroach will die, but only because it cannot eat or drink, not because of nerve damage or lack of oxygen.

Whet Your Appetite with a Live Roach Eating Contest

As part of their promotion for Halloween in 2008, the Six Flags theme park came up with one of the craziest contests. To win this contest, competitors had only one goal: to be the one to eat the most cockroaches in five minutes. The winner would win free park passes for his or her victory. A doctor advised against this contest because certain microorganisms living inside the insects can pose serious health risks. This apparently didn’t deter brave contestants, however, because in 2011, the contest was brought back due to “popular demand”.

Roaches Are Incapable of Learning New Things in the Morning

Cockroach facts tell us that cockroaches are nocturnal, but did you know that they really are unable to function properly in the morning? Research shows that cockroaches are not able to form new memories at the break of dawn. To test this theory, researchers tried to teach roaches to like the smell of mint, which is not usually their favourite smell. Group of roaches were given mint-scented sugar water at different times of the day. If the mixture was given in the afternoon or at night, the cockroaches eventually learned to like the scent. If the mixture was given in the morning, however, the roaches failed to recognise the scent of mint as a good signal.

Roach Fighting Is a Very Old Sport

With roaches walking the earth since millions of years ago, it’s no wonder that humans eventually found ways to be entertained by them. The first game of cockroach fighting is believed to have taken place in China. The practice was brought to the United States around 100 years ago. The New York Times reported a story in 1886 about a group of Chinese men who staged cockroach fights in different cities, attracting thousands of dollars in bets. That was a significant amount of money at the time, especially considering the fact that they probably recruited the fighters for free.

Roach Racing for a Good Cause

If roach fighting is too exciting for you, roach racing may offer a more lighthearted way to be entertained by cockroaches. This sport actually is international, having a presence in the US and also in Australia. In Maryland, students of Loyola University started a tradition of roach racing every fall. Cockroaches are raised and trained for the race. They are even given names such as “the Green Machine”. In Australia, roach racing became a regular charity event in a Brisbane pub. The tradition has been raising funds for different causes for over three decades.

There Is a Cockroach That Glows

In 1939, scientists discovered one of the rarest species of cockroaches in a remote area of Ecuador. This species is named Luchihormetica luckae. To date, there has only been one specimen of this species found. The special thing about this cockroach is that it can glow. The cockroach appears to be quite similar to the bioluminescent click beetle, a toxic bug. The light that it produces may confuse predators and give it the protection that the beetle also enjoys. Unfortunately, the area where this specimen was found was later destroyed by a volcano, so the roach may have become extinct.

One Million Cockroaches were Found in a House in New York

In 1979, a house in New York was so crowded with cockroaches that they could be seen pouring out onto nearby lawns, tree trunks and even the walls of neighbouring houses. It was estimated that there were a total of 1 million (or even more) cockroaches in the house. Aside from the roaches, the house was also home to 24 dogs, 20 cats, 2 mice and a parrot. When the police arrived to investigate complains about a barking dog, they saw that every wall inside was covered with cockroaches. A 64-year-old woman was found in the house with roach bites all over.

Cockroaches Are in Popular Demand in China

In most places around the world, cockroaches are unwanted, and pest control measures are taken to get rid of them. One of the more surprising cockroach facts, therefore, is that they are actually hot commodities in certain places. Cockroaches are raised in farms in China. Many consumers in the country believe that dried cockroach is an effective ingredient in various health and beauty remedies. Cosmetics companies use cockroaches in powdered form to add into their products. The biggest cockroach farm in China has 10 million crates filled with cockroaches.

The Largest Species of Cockroach Can Be 3 Inches Long

The sight of a giant burrowing cockroach might not be pleasant for the faint of heart. This cockroach is known as the heaviest species of cockroach in the world. A burrowing cockroach can weigh up to 1.2 ounces, or 35 grams, and can grow over 3 inches long. This cockroach can live as long as 10 years, while a regular roach generally only lives to be a couple of years old. The giant burrowing cockroach is native to Australia. Despite its massive size, the giant burrowing cockroach is actually quite friendly and is not considered a pest.

Cockroach Facts – Facts about Cockroaches Summary

The cockroach is one of the most common creatures on Earth and can be found on every continent. There are many surprising cockroach facts that can help us understand more about this insect. The anatomy of the cockroach proves to be quite interesting: each cockroach has 18 knees, and its brain is located within the body instead of the head. This means a cockroach can live for almost two weeks without its head. Roaches can carry over 30 types of bacteria, and can cause serious health issues for humans. Roaches are in demand in a few places, however, such as China, where they are farmed.
