The cockroaches are back! Reasons for the disappearance of cockroaches and their reappearance Why cockroaches are massively returning to the apartments of Russians
Many are concerned about the question of where the cockroaches have gone. Turning on the lights in the kitchen, people no longer see insects hastily fleeing. No one is rummaging around in the trash can. The hosts carelessly, already out of habit, leave a bowl of cookies on the table. And some even almost forgot what these insects look like.
Finally, the pests that dragged a bunch of pathogenic microbes into human dwellings no longer bother. But something prevents people from rejoicing and enjoying freedom, strange doubts torment them. Can a person feel completely safe in buildings where even insects leave? This question has been asked more and more often lately.
Really, maybe all this is not good? After all, cockroaches, who are masters of survival even in adverse conditions of existence, could not go anywhere without a good reason.
Scientists are puzzled, psychics are puzzled, disinfectors are bored. There are many explanations for this phenomenon, and some of them are quite unexpected ...
Let's look at the proposed explanations in more detail.
Cockroaches couldn't stand electromagnetic radiation?
One of the most reliable explanations why cockroaches have disappeared is the constant high-frequency electromagnetic effect on them in human dwellings. Residential buildings and institutions are crammed with a variety of equipment. During operation, it forms an electromagnetic field, which creates unfavorable conditions for.
Here are the devices that researchers are ready to name the culprits of the death of cockroaches:
- Cell phones.
- Microwaves.
- Computers.
In recent decades, such devices have firmly entered our lives. The question of their safety for humans and animals is still being discussed, and there are more and more arguments about the harmful effects of radio frequencies every year.
Scientists have suggested that the Prussians, with their inherent sensitivity, were the first to react to electromagnetic radiation, so they left the cities, left the high-rise buildings in which they were so comfortable before.
It has been noticed that for some reason there are no cockroaches in those regions where the old GPRS and GSM standards are in effect. These include Russia and most countries of the Near Abroad.
Are GMOs to blame for the death of cockroaches?
People are not without reason worried, where did the cockroaches go, because they ate our supplies? Increasingly, genetically modified foods began to appear in the human diet. Is this what is meant to save humanity from starvation or what will finally destroy it?
More than one large-scale experiment in authoritative laboratories is devoted to the study of the safety of GMOs (genetically modified organisms, primarily for agricultural purposes). And the first results are not comforting.
Most experts sound the alarm. Missing cockroaches? This is nothing compared to the consequences of tampering with the genetic code. They are difficult to predict. All links in the food chain suffer: an insect that has tasted a product of genetic engineering, a duck that has pecked at an unfortunate insect, a mammal whose victim is a bird.
Unfortunately, until the harm of a particular product is proven, more than one generation of people will suffer. Researchers are convinced that cockroaches disappeared as a result of systematic food poisoning from the human table. I don't want to be the next victim.

We catch cockroaches and test different means on them - see the results...
Created a perfect insecticide that killed cockroaches
People who are tired of fighting unpleasant synanthropes want to believe that cockroaches have disappeared forever. Probably, the employees of the disinfection stations began to work perfectly and, armed with a powerful insecticide, rid the apartments of insects, just as doctors defeated smallpox through vaccination.
That's why there are no cockroaches in Moscow. For a long time and often to no avail, chemicals were scattered and sprayed by people around their own homes, but the moment has come when new advanced technologies have made it possible to create drugs that are many times more effective than previous pesticides.
This is what worries skeptics. Insects sooner or later adapted to any poisons, and it is very doubtful that some unique insecticides that can finally destroy them already exist. Looks like the cockroaches just gave us a break.
Science does not stand still. Despite the successes achieved, scientists are preparing for the next stage of the battle with insects. The new weapon, according to their calculations, will lead to the fact that the cockroaches that live in human dwellings will finally finally die out.
Highly Expected Tool Is a Virus- the causative agent of a deadly infection, fortunately, exclusively among cockroaches. It attacks the cells of their digestive tract. Before the insect dies, it has time to transmit the infection to a bunch of its relatives. That's when people will finally stop wondering where the cockroaches have gone.
Cockroaches were too tough for plastic and linoleum
We ourselves are to blame for the fact that cockroaches have disappeared somewhere. No one will argue that the appearance of modern apartments is significantly different from the conditions in which people lived 20-30 years ago. Paper wallpapers were replaced by plastic panels, and the owners began to hide the wooden floor under a PVC coating, they also learned how to make furniture from artificial materials imitating wood or stone.
Not every middle-class citizen can afford expensive repairs using natural raw materials. This led theorists to the idea that it was the excess of synthetics in the room, which often had a pungent odor, that was the reason that the cockroaches left in an unknown direction.
Cockroaches couldn't stand the competition
The fact that the Prussian gradually ousted the Black Cockroach from human buildings has long been known to entomologists, and they easily interpret this fact. Fertility, rapid maturation, care for offspring allowed the red cockroach to prevail over its black counterpart.
But the question of why the Prussians themselves disappeared from the apartments remains open. Could these peaceful creatures eat each other? Cannibalism is a phenomenon not alien to cockroaches. However, it is not so widespread that an entire nosological category of insects ceased to exist. Yes, and, as a rule, defective individuals are eaten, or laying eggs, recklessly left in a conspicuous place.
But cockroaches have another rival that claims the same habitat - a domestic ant. Some seriously believe that this creature, much better organized and, like the Prussians, omnivorous, has a better chance of winning in the competitive struggle.
Natural rivalry in the animal world is an integral part of life, a way of regulating population size, the basis of evolution. But still, this is not a very convincing argument explaining where the cockroaches have gone.
Is the disappearance of cockroaches a harbinger of an economic crisis?
What were the Prussians afraid of? After analyzing the current situation, scientists from different countries came to an unexpected opinion: cockroaches felt the approach of the economic crisis that erupted in 2008.
This bold guess of entomologists is indirectly confirmed. Recently found a huge thriving cockroach colony in the Indian state of Goa. No financial cataclysms affect this territory, which is probably why insects live there so freely. Now we know where the cockroaches have gone.
Cockroaches completed their mission on Earth and retired
Perhaps the most incredible version of where and why the cockroaches disappeared was put forward by ufologists. They are confident that these insects, living side by side with humans for thousands of years, are space spies. Pretending to be stupid creatures, they were able to obtain comprehensive information about the life of Homo sapiens, penetrating into the most intimate corners of our lives, without needing either passports or passes.
The cockroaches have disappeared, because now their honorable mission is completed, they were able to safely leave our homes and return to their planet. Only it is unlikely that anyone will provide indisputable evidence incriminating cockroaches in espionage.
The cockroaches will definitely be back
It would seem that cockroaches have nowhere to disappear. Whether they were frightened by the bell ringing of the restored temples, or the high noise level of megacities, or killed by the food additive E450, or they flew away to their planet - no one knows for sure.
Where did the cockroaches go - this is certainly not the worst problem that should worry humanity. According to biologists, the number of insects is characterized by undulating fluctuations. This is a natural process.
And, finally, the most important thing that is designed to reassure suspicious people: it seems that soon a slightly different question will stir up on the Internet: why cockroaches have appeared again. Information about their "safe" return to apartments and cottages has already appeared.
They are no longer hindered by European-style renovations, an abundance of mobile phones and modern poison, they are still ready to eat food from our table, including GMOs. No need to be surprised, because cockroaches have repeatedly proven their ability to adapt ...
The news that cockroaches did not disappear anywhere, if it does not please, then console. But you need to think about something else. Will the current stasik, as before, be peaceful and shy, or will people have to deal with a mutant - bold, wiser, resistant to poisons, able to gnaw the skin of sleeping people at night (there is a lot of evidence that cockroaches do this).
Be that as it may, but a new stage of the struggle for the freedom of the home from insects has begun.
Interesting video: where did the cockroaches go?
It seems that Amur residents who disappeared from the apartments are returning from distant wanderings, as well as pets of Barnaul. Those who were thrown at with slippers and poisoned with chemical Chinese pencils. Those that have been missing somewhere for several years ...
- Ugh! Yesterday at home I saw a cockroach crawling on a cabinet with dishes. And it became so disgusting ... Really returned back? After so many years of absence of the mustaches, I have already forgotten what they look like, - our regular reader told the "City on the Amur". Due to the piquancy of the topic, not every housewife admits that red-haired creatures live in her house. However, as it turned out, this issue again becomes topical for many.
Apocalypse
Maybe the advent of the Prussians happened because they suddenly pushed back the end of the world? And, apparently, the rumor about the new Mayan calendars, according to which the end of the world is pushed back, was not only among people. And there is no point in running away and hiding for insects at the moment. Here are cockroaches for joy and crawled out of their secluded cracks.
According to Vanga's prophecy, the insects were the first to feel the approach of the Apocalypse. (In addition to cockroaches, bees from the USA and Europe disappeared somewhere.)
The population has declined
Cockroach Speculation is speculation ... Well, what do entomologists think about the return of the Prussians? Why did these insects return after years of absence? - we asked the Annunciation scientist, candidate of biological sciences Dina Rogatnykh.
- In fact, they never disappeared.. Just in connection with the advent ten years ago of a large number of new chemical and biological preparations for cockroaches, the population has noticeably decreased.
- What factors contributed to the "return"?
- Cockroaches - one of the most adaptable creatures to environmental factors - over time simply adapted to poisons, and now their numbers are recovering. The only chemical substance that insects have not been able to get used to in the process of evolution is boric acid.
- Will the cockroach infestation be as massive as before? When it was scary to spend the night in hospitals: insects crawled everywhere. I had to sleep with cotton swabs in my ears. Did the walls of student dormitories literally “move”?
- I think no. Firstly, the chemical industry does not stand still and new poisons and other household chemicals are constantly being created, and secondly, people are increasingly using synthetic building materials that the cockroach does not eat.
- Is it humane to kill cockroaches with slippers and chemicals?
- It is difficult to talk about some kind of humanity, planning a murder. In addition, you can hardly kill a cockroach just with a slipper. For example, he can live for several days without a head. It's just that the nervous system of insects is arranged in such a way that the head does not play the most important role. When it is lost, the body is controlled by nerve ganglia, that is, nodes. After some time, the insect, of course, will die, and not so much from the inability to eat, but from dehydration. For a long time without water cockroach to be can not.
- Such factors of the disappearance of the Prussians as the absence of the ozone layer, the Svobodny cosmodrome, mobile communications, and the Internet are listed. What do you think is real, and what is far-fetched?
- It is believed that high-frequency mobile communications have an effect on cockroaches. Everything else is nothing more than myths.
cockroach heart
G they will talk about some universal benefit of cockroaches ...
There are no useless creatures in nature. In fact, the species of cockroaches that live with humans recycle our garbage. Them 
the digestive system contains the so-called symbiotic Blattabacterium bacteria, thanks to which the ordinary Prussian can digest almost everything: the remains of any food, paper, rags, etc.
To some extent, cockroaches save us from other unpleasant insects - bedbugs and moths, destroying their eggs with pleasure.
Well, recently, for medicine, natural antibiotics contained in the hemolymph (one might say, blood) of cockroaches are of interest. Nine such substances are now known. It has been experimentally proven that they successfully destroy E. coli. It is quite possible that after some time, thanks to the Prussians, new effective medicines will appear.
The principle of the cockroach heart (imagine - an insect has it!) served as a prototype for creating an artificial human heart. It is currently being developed in India. The heart of a cockroach has many chambers: if one fails, the remaining ones take over its function. Perhaps the invention, which has already been tested on frogs, will someday save human lives, says Dina Rogatnykh.
Story
The fossilized remains of representatives of the order of cockroach paleontologists have already been found in the upper deposits of the Carboniferous period, which means that the mustachioed live on earth for more than 300 million years. And they saw how dinosaurs appeared and disappeared, while they themselves survived.
The big black cockroach lives everywhere except perhaps Antarctica. In Europe, he showed up more than three hundred years ago.
As for the appearance of the red cockroach (Blattella germanica), it is associated with the Russo-Prussian war in the middle of the 18th century. There is an opinion that Russian soldiers returning to their homeland in 1762-1763 after the Seven Years' War from Germany brought cockroaches in coat collars and knapsacks. Therefore, insects were called "Prussians". In western Germany they are called "Frenchmen", in eastern Germany - "Russians". The opinions of scientists about the place of origin of insects differ: for some it is Africa, for others it is South Asia.
Once upon a time, people revered cockroaches (although, to be honest, it's hard to believe!). It was believed that if there are any in the house - expect profit and wealth. They were even used as a medicine - they were added to vodka, which was called “cockroach”.
A long time ago, among the Tatars, “tarkhans” were called a privileged layer of society, exempted from paying taxes for special merits. And in Russia, hordes of mustachioed parasites began to be called that. It's just that the word "tarkhan" was transformed into "cockroach".
running
Anyone who has ever tried to catch a cockroach knows that this is not an easy task. What is the cockroach secret? Firstly, the cockroach has small hairs on its abdomen on both sides, with the help of which the insect catches the slightest movement of air, and also determines from which side to wait for the enemy to attack. Secondly, the cockroach's nervous system is simply amazing: it only takes a hundredth of a second to assess the situation and run away!
Geoffrey Kamhi of the Hebrew University of Jerusalem and his colleagues filmed insects with a high-speed movie camera. And it turned out that cockroaches can move at a speed of one meter per second and at the same time change direction up to 25 times per second. “We don’t know of any other animals capable of coordinating the direction of movement like that,” Kamhi said. - If cockroaches were not such unwanted guests in the house, they would, no doubt, be quite deservedly admired.
No wonder cockroach races were very popular in Russia before the revolution. They began with Moscow taverns. Mostly black insects participated in the competition. Half of Moscow came to cheer for the cockroach, nicknamed Yegor, in one of the taverns. The running track is no more than one and a half meters long, the stakes are considerable. There are cases when on such a totalizator lost fortunes.
astronauts
A few years ago, students of the Burdenko Voronezh Medical Academy caught 54 cockroaches in city hospitals. And the Prussians went into space on the Photon-M-3 biosatellite. Reds were chosen for their light weight and size, as well as their ability to live long without food.
The result of the experiment shocked scientists. They have grown to gigantic proportions. And in addition to this, instead of one offspring expected during this period, they brought as many as three.
Museum
In the US state of Texas, the owner of a pest control shop, Michael Bodan, has created an unusual museum that displays dozens of species of cockroaches, donated from different people.
Passionate lover of cockroaches - he took care of the posthumous fate of his "crumbs". He places dried cockroach mummies in different interiors, arranges houses, cradles for them, makes beach hammocks, umbrellas, deck chairs ... Visitors can admire Prussian surfers, Prussian musicians and even the “Statue of Cockroach Liberty”.
Is it possible to cause admiration for the sight of dead cockroaches? It turned out, as much as possible! Especially if you dress them up in suits. So the audience is invariably delighted with the sexy cockroach "Marilyn Monroe" and touched by the mustachioed "Elvis Presley" in a white tailcoat with rhinestones.
One of the exhibits was created by an 85-year-old woman who dressed an insect in a mink coat and placed it behind a tiny piano. The composition "Liberouty" is named after his idol, the famous American pianist.
Facts about cockroaches
The international name of the cockroach - "cucaracha" - is of Spanish origin, and migrated to English in the early 17th century.
More than 4 thousand species of cockroaches live on the planet. Almost all of them live in the wild, 80% in tropical forests.
According to various sources, there are several largest cockroaches in the world. Some call the Colombian female Kwgaloblatta longipennis, which reaches a length of 9.7 cm, a width of 4.5 cm. Others call it a winged Cuban cockroach up to 10 centimeters long. Still others are the Australian rhinoceros cockroach (Macropanesthia rhinoceros), which is over 9 cm long and weighs about 33.5 grams. The inhabitant of our apartments is much smaller: Prusak - from 10 to 13 mm long.
The Madagascar cockroach, while moving, hisses quite loudly, making his way and, as it were, shouting: “Make my way, my way!”. Filmmakers have discovered this and successfully use the cockroach's voices to voice special episodes.
Much is said about the fact that only cockroaches will survive after a nuclear explosion. But these conversations have no definite scientific confirmation. Although there are studies confirming the resistance of cockroaches to radiation. A human can withstand 500 rads (units of exposure to radiation), but a cockroach can withstand 6400 rads!
Information or misinformation?
About 10-12 years ago, urban residents were pleasantly surprised by a sharp reduction, and in some places - the complete disappearance of long-standing and rather intrusive "companions" of man - cockroaches. How long have they left our homes? Maybe forever? Unfortunately, both questions can now be answered with one answer - no!
irreconcilable struggle
“Where there is human habitation, there we are!” Six-legged insects observed this rule strictly for many years. The only exceptions are those cockroaches that live in hot regions of the planet. There they can easily do without a person.
A cockroach may well become a carrier of various kinds of diseases. So this insect is not useful. That is why the struggle of man with cockroaches, which has been going on for more than one century, is becoming increasingly irreconcilable. Who will win - Homo sapiens or cockroach?
At first, people clearly lost. Dichlorvos, poisonous baits and traps did not always help and not immediately. This required patience. In addition, you can suffer from pesticides yourself, and there is nothing to say about pets - cats, dogs and others.
In fact, the worst enemy of a cockroach (besides a house slipper) is the cold. Already at a temperature of + 5 ° C, the cockroach begins to feel extremely lousy, at -5 ° C - it dies within half an hour, and at -7 ° C - in a minute. But it's not so easy to freeze the whole house and not freeze yourself.
Another way to get rid of annoying Prussian neighbors is to deprive them of water. Without food, cockroaches easily manage, but thirst destroys them very quickly. But try to remove all the water from the house! After all, one drop is enough for these creatures, even wet earth in a flower pot, to restore their strength and continue a comfortable existence in a human dwelling.
Suspicious Disappearance
And now, when humanity was ready to surrender to the mercy of the winners, these same winners, that is, cockroaches ... disappeared!
Suddenly, residents of cities and large towns discovered that the red insects, impudently walking around the kitchens and bathrooms at night, and even in broad daylight, suddenly disappeared, no one knows where. What versions were not put forward by scientists about the disappearance of these annoying "companions" of man. It was assumed that the reason for the capitulation could be more advanced plumbing - the cockroaches had a “dry land”, and they went to where it was damper. It is possible that insects that feed mainly on the remains of products, now, as a rule, genetically modified, have undergone changes in genetics, and cockroaches have safely died out (which is what awaits us in this case). Someone believes that European-style repairs with the use of "chemistry" and non-environmental materials adversely affected the Prussians. For some reason, some people blame high-frequency mobile communications and microwave ovens for everything, which is hardly true. After all, cockroaches, like scorpions, are able to withstand exorbitant doses of atomic radiation, what can we say about cell phones and kitchen appliances?
Some people suggest that the biological rhythms of cockroaches were knocked down by the destruction of the ozone layer in the atmosphere of the planet, and they went in unconsciousness to no one knows where, if only to get away from people.
Ufologists also contributed to the search for the causes of the disappearance of cockroaches: they suggested that the latter were scouts for space aliens. And so, having collected enough information about people, they finally got away.
True, they have been collecting this information for a very long time ... However, why not?
In any case, the number of red cockroaches has declined sharply. And so sharply that some scientists even offered to list them in the Red Book. Although which living creatures has it ever helped?
Hello again!
The matter did not reach the Red Book. Do we shout "Hurrah!" or “guard!”, but the fact remains that they are returning. And these are no longer those pampered, unhurried, patriarchal, one might say, insects that scatter in the corners, it was only necessary to turn on the light in the kitchen at night. No, these are those who managed to survive in the conditions of European-style repairs, cellular communications, harassment with "chemistry" and GM products.
Those who do not care about the ozone layer and microwaves. Large, unpretentious, nimble, tenacious, with a powerful shell, which now not every slipper - and not the first time - is able to crush, they reappear in our homes. Some of them even know how to fly - real mutants! Voronezh, Volgograd, Moscow, St. Petersburg - signals about a new invasion of cockroaches come from everywhere.
And this is not only a problem of Russian cities. In June-July 2012, Naples was literally attacked by red cockroaches - carriers of typhus and hepatitis. The authorities were even forced to carry out a complete disinfestation of the city.
So with the onset of the 21st century, the war against cockroaches has not ended - it has simply moved to a new level.
By the wayAs strange as it sounds, cockroaches have healing properties. In Eastern medicine, wingless females and larvae of cockroaches are prescribed as a means of regulating the activity of the gonads, as a drug that has a diuretic effect and promotes bone fusion. In Russian folk medicine, black cockroaches were used as a diuretic for dropsy. L.I. Stekolnikov and V.I. Mukhor quotes the statements of the German surgeon Johann Schober (1725): “And if a person has impotence of the stomach, then having caught cockroaches, throw them into boiled water, and if someone uses it in good order with abstinence in food and life, then healing can absolutely get. Later, this water heals various severe diseases, namely: festering wounds, from water, when it begins ... "

==From various forums:

The most plausible version is the disappearance of cockroaches due to high-frequency mobile communications. Moreover, in Ukraine and Russia, as well as other CIS countries where GSM and GPRS standards are in force, it was cockroaches that became victims. Other countries where third-generation standards (UMTS and CDMA 2000) are common have been less fortunate - honey bees are dying en masse there.
http://dnepr-forum.com/topic2091.html
Just crushed a fleeing creature in the bathroom. I have not seen cockroaches for a hundred years, but never like this at all. Not red, as under socialism, but a black-whiskered cockroach. Like from the fairy tale "cockroach". One to one.
It turned out that these are black cockroaches (not to be confused with Madagascar). They are also called mine, basement or sewer, according to their habitat. The size of an adult's little finger, they run very fast, they feed on rot. It is not clear how they got into an apartment with a European-style renovation, where there are no cracks and gaps. Possibly from the basement through the balcony.
Traps from cockroaches are not suitable for them (they will not crawl through). I bought the Raptor gel for 30 UAH. Yesterday I anointed, today I found the first dead one under the bath. It seems to have helped.
Here is such a thing that helped - gel raptor:
Giant black cockroaches appeared in Dnepropetrovsk
Entomologists explain the massive invasion of creepy insects by abnormal heat.
Owners of private houses and apartments on the first floors began to complain about the appearance of strange huge cockroaches in their homes.
Moscow is being invaded by giant cockroaches
AMERICAN METROTARAKAN - TTX:
Length: 4 - 5 cm. Width: 1 - 1.5 cm. Lifespan: 9 - 10 months. Speed: up to 0.75 m/sec. Special qualities: winged, scary.
Yes, this is a tropical cockroach, the larva of Periplaneta americana Linnaeus, - Andrey Ukrainsky, a researcher at the Faculty of Biology of Moscow State University, identified the proud profile of the insect. - It is also popularly known as the American cockroach. Adults are winged and reach five centimeters in length (for comparison, this is the width of an ordinary plastic card). And, by the way, this species has densely populated Moscow basements and metro tunnels in recent years. There, the conditions that he loves very much are warm and humid. It is for this reason that if such a cockroach crawls into an apartment, then it will live and breed no higher than the 1st floor: further it is too dry for it.
The Americans run very fast. Therefore, it is this species that is usually used for cockroach races.
All four types in comparison:
My grandmother, I remember, took care of the blacks, explained just the opposite: where there are blacks, redheads do not live there. She said the blacks destroy the clutches of the red ones.
Redheads are just a plague, bespredelschik. And blacks are very intelligent and unobtrusive creatures.
Yeah. Blacks are almost invisible, they do not strain. So, meet once a month in the hallway, politely miss. That's all their presence.
And red cockroaches and house small ants greatly interfere with life, climb everywhere and fill the housing.
From Omsk, we are informed about a large number of cockroaches occupying the streets of the city.
Ludovit : The fact is that for many years there have been no cockroaches (the so-called "Prusaks") in the city at all, and blacks have disappeared from us more than 50 years ago (he himself saw only one black in the 50s in preschool age ). And here you are on you! What's taco?! Where?!
Directly, read, in the center, opposite the House of Press, at night near the shopping center "Cascade".
During the day there are no goats. But at night, as it becomes dark, that is, they climb out, cholera is like that, and run up and down the sidewalk. There is a darkish alleyway and people go on their way, not seeing anything - something, it seems, crunches under their feet - and figs with it ... They don’t pay attention to some nonsense at all. But if you shine a flashlight, then passers-by, seeing _this thing_, groan and gasp and express themselves in every possible way.
The main thing is that in other regions nothing like this can be seen - not heard ...
