Cockroaches



These insects on the planet have more than 4,500 species. Cockroaches are quite ancient creatures that lived back in the Paleozoic, hundreds of millions of years ago. These flat and very mobile creatures adore moisture and warmth. A number of cockroaches for their dwelling have chosen a man’s dwelling, tying their way of life to ours.

Despite the general dislike of these insects, they can not get rid of them. But it turns out that cockroaches have a number of amazing properties. True, some of them are even exaggerated with the help of myths. It is worth learning more about such familiar, but also such mysterious ancient creatures.


Cockroaches

Cockroaches are able to survive the nuclear winter, after which they will become the kings of nature.

The famous American program Destroyers of Legends conducted an interesting experience. Radioactive cobalt-60 was irradiated with red cockroaches, known more as the Prusaks, the flour beetles and the fruit fly flies. It turned out that the latter could tolerate higher doses of radiation than cockroaches. And best of all, beetles have adapted to radiation. Scientists have found out that cockroaches can withstand radiation that exceeds the death rate of a person by 15 times. So if these insects will undoubtedly survive a nuclear winter, serious rivals will meet them on the way to conquering the world.

Cockroaches can survive being underwater.

Again, this statement undertook to check the “Destroyers of Legends”. For 20 minutes, five cockroaches were placed in a container of water. After that, the insects did not show signs of life, it seemed that they had died. However, a day later the cockroaches “came to life”, so this statement was true.

A cockroach can live without a head.

This myth can be checked by everyone. For those to whom the result itself is important, but to engage in fishing for a poor cockroach and its torture, we will immediately report that this is true. For a while these insects can really do without the head. The fact is that insects do not have such a circulatory system as in warm-blooded animals. As a result, cutting off the head will not be accompanied by blood loss and will not end with a quick death. And the respiratory organs of cockroaches are represented by spiracles scattered throughout the body. Without food this insect can live up to 45 days. So, having lost a head, the cockroach will lose the organs of sight and mustache, which it perceives. Death will come from hunger, about a month later. The poor creature will simply have nowhere to eat.

Cockroaches – peaceful creatures do not feed on other creatures.

By nature, these insects are really non-aggressive. They’d rather run away than fight. Cockroaches subconsciously seek security, attacks on other creatures can not be said. However, it is worth remembering that these insects are omnivores. That is why a long absence of ordinary food can push them and attack on living beings. Only they should remain in a state of rest, for example, sleep and visually not be represented as dangerous.

Cockroaches can fly.

Since cockroaches are insects, all species have wings. They make cockroaches similar to a seed, which allows them to be referred to this class of creatures. But not all cockroaches can fly. Only some species living in wildlife have such a gift. And the vast majority of species, including redhead, and black cockroach fly under normal conditions can not. But during the breeding season, they can rise into the air. Also they are forced to spread the wings of the light source.

There are white cockroaches and albino cockroaches.

Some species can really boast of representatives of white color. However, it has been scientifically proven that there are no albino cockroaches in nature. These creatures can change their color for a few hours during molting. Then the old shell is dropped, and the new one has not yet received normal properties. Also white cockroaches can become due to the effects of certain types of poisons, in particular those used for domestic extermination of insects.If the apartment has unusual white cockroaches, then the victory of a person is already close.

Cockroaches do not pose a danger to humans at all.

It turns out that an unpleasant appearance is not the most terrible thing for these creatures. They are quite dangerous for humans. In particular, the odor that stands out from the glands of such insects is unpleasant, some asthmatics react to it. And evaporation, coming from cockroaches, can cause allergies. The most important thing is that cockroaches are carriers of bacteria. That’s why you can not leave food at night on the table. After all, it will not only be a source of food for cockroaches, they will also infect it. If these insects do not have enough food, they will eat plants, paper and even skin. That is why the abundance of cockroaches in the house will be harmful not only for the person, but also for the surrounding environment.

Cockroaches cause asthma.

About 50 years ago it became known about the existence of a direct connection between cockroaches and allergic diseases. This is especially evident in the case of asthma. In each city high-rise building there are from one to three hundred thousand different insects. Most of them are cockroaches. Scientists believe that most allergies occur precisely in homes, since people, especially children, are there and spend most of the time. There are periodic allergies that are related to the seasons, but there are allergies all year round, which can cause cockroaches.

Cockroaches eat the remains of human food.

As already mentioned, these insects are omnivores. It is best for them to eat what is left of human food – crumbs, leftovers. In addition, cockroaches adore sweet. If such a meal is difficult, then they try to find food among the garbage. Cockroaches do not disdain products of rot and other wastes. If there are no food remains in the garbage, the insects can eat plants, paper and skin. Cockroaches reproduce by laying eggs.

The sexual way is used to propagate cockroaches. Sometimes female cockroaches are capable of pathogenesis, from their unfertilized eggs can grow a normal individual. Usually, as a result, a male appears in the light. This is how the sex ratio of cockroaches is regulated. When a female is impregnated, she carries a ootheka in herself. In this capsule, eggs are stored. When the time comes, the female cockroaches lay eggs in a secluded place, inaccessible to other insects. However, not all cockroaches reproduce as follows. There are viviparous species, for example, Madagascar cockroaches.

Cockroaches do not know how to bite.

And again we remember the omnivorousness of insects. These creatures can eat any food of animal origin. When a person sleeps and is practically immobilized, cockroaches can even try to bite people.

Cockroaches feed on bedbugs.

This is a fairly common misconception that is untrue. The fact is that between these creatures there is no natural competition for food. Cockroaches are omnivores, and bedbugs are bloodsucking. The first can attack the second only in an exceptional situation, when there is no other food.

Cockroaches do not make sounds.

There are sizzling cockroaches. One kind is called – Madagascar hissing. When moving, these insects make a loud hiss. Thus, cockroaches are clearing their way, warning everyone that it is better to leave the road. This feature was even noticed by filmmakers and now in some films one can even hear cockroaches.

On the back of the cockroaches die.

This is indeed so. If the cockroach falls on its back in a flat place, for example, on the surface of the table, then he himself will not be able to overturn. All he can do is twitch. As a result, the cockroach will die. If there are leaves, branches or pebbles on the surface, then the insect may well be able to catch on to them and be able to overturn. That’s why substances that paralyze the muscles of insects are added to pesticides.

Cockroaches globally affect nature.

It turns out that these creatures make a weighty contribution to global warming. Cockroaches every 15 minutes produce gases. And even dying, they continue to do this for about 18 hours. In total, all the gases released by insects on the planet constitute about a fifth of the methane emissions. Cockroaches the same gases in these 20 percent occupy an important place. So cockroaches have a certain impact on nature and on warming. Cows and termites can boast of this kind.

Cockroaches are eaten.

In some countries, eat cockroaches, including for medicinal purposes, are especially appreciated in this regard, black cockroaches. It turns out that these insects contain three times more protein than chickens. In Chinese cuisine, candied cockroaches are a fairly popular dish.

You can destroy the cockroaches on your own.

Many believe that it is possible to defeat annoying insects without calling specialists. However, making self-made baits, purchasing popular means not only does not lead to the final destruction of cockroaches, but only makes the situation worse. After all pests gradually get used to preparations, it is possible to reduce insects a little bit. Conventional household products have a point effect and do not have a long-term effect. So for a hundred percent guarantee of cockroach withdrawal it will be better to take the help of professionals.

Cockroaches can be destroyed forever.

Some companies believe that after the treatment of areas the cockroaches will disappear once and for all. In fact, to achieve this is almost impossible. After all, after getting rid of “their” insects, the empty area will immediately become the object of close attention of other creatures. Over time, they will want to settle in free territory and will make every effort to do so. It is worthwhile to understand that many one-day firms use this myth and deceive their customers, promising cheap processing with a long-term guarantee. If a new generation of cockroaches in a few dozen individuals gets into the warm generation, the next generation will increase the population thousands of times. That is why the best effect is achieved only by quarterly and regular processing. This is the only way to prevent cockroaches from multiplying.


Cockroaches live only in dirty houses.

In fact, even in clean dwellings, you can meet these insects. Just their colonies are more in dirty dwellings, because access to food is facilitated. Therefore, it is easier to meet cockroaches.

Cockroaches do not hibernate.

This is not true, in America, for example in the northern territories there are wild species that fall into hibernation.

Cockroaches are afraid of light.

Most species prefer darkness, but some cockroaches, on the contrary, tend to light. You can see them at the window or near the TV screens at night. Most cockroaches run up if they are lighted. However, such a reaction is more evidence of fear of man, and not of fear of light.

Human hair and nails are the favorite food of cockroaches.

This myth appeared a long time ago. Sailors of ancient sailing ships told how their nails at night gnawed cockroaches. However, today this is impossible, except that the insects will be very hungry. Hair and nails can have a limited nutritional value for the cockroach. After all, hair can be fat, and nails – dirty. But such food is very difficult to compete with a variety of food found in the house. So you can sleep peacefully, just watch the ears. After cockroaches can try to look for food in the ear canals.

Immature cockroaches can develop in human wounds or fast foods.

This myth is related to the previous, affirming the love of these insects to human flesh. In fact, cockroaches develop in moist and warm areas, but for this human flesh is not used. Bites are possible, but even in rare cases.

Cockroaches need to eat constantly.

So it seems, as the cockroaches are constantly moving, as if in search of food. In fact, these insects can live without food for about a month. As for man, wherever it is more important – the presence of moisture. For example, the Prussians can live without water for about a week. True, in nature there are desert cockroaches that can survive without moisture for a long time.

Cockroaches

Despite their habits, cockroaches are pure creatures.

To prove this myth, they say that cockroaches are able to self-clean. In fact, the reality is that these insects are very dirty. They live and eat in garbage, sewage, waste. There they pick up and carry bacteria on their antennae and legs, spreading them everywhere they go, including our food. Cockroaches eat contaminated food, diseases are also transmitted through their own waste of life. So these insects are dangerous, regardless of whether they can clean themselves.

If you step on the cockroach, then its eggs can get stuck in the shoes, and then multiply already in the house.

This myth is probably incorrect, although it has been intensely discussed. If the cockroach is really crushed, then in any case it is better to clean the shoes. It is better not to risk the appearance in your house of hundreds of eggs of an insect. It’s better to secure yourself in advance than to start dealing with problems that have arisen.
