Cockroach: what is dangerous for himself and his bites, what diseases can he transmit to people

Hello! Here I am amazed at my brother. He treats some vital moments so disregard that he already infuriates.

Well, for example, over the past year, I was visiting him four times and constantly saw cockroaches. To comments on this subject, he only shrugged and said that they did not interfere with him.

I had to tell and explain with live examples why the cockroach is dangerous. On the fifth attempt, he heard me and began to take actions to get rid of them. Now I will share with you detailed information about these insects.

What danger are cockroaches for humans

Cockroaches have become a real problem for humans. These insects can accompany us everywhere: at home, at work, and in catering facilities, and in hospitals. In addition to the unpleasant appearance and disgust, the harm from cockroaches is considerable for a person.

I must say that these are not only unpleasant insects, but also creatures that can bring a lot of problems to a person. Harm from cockroaches is expressed in the following:

Cockroaches harm to humans is scientifically proven. Their extermination is a priority, since insects are capable of causing significant harm.

In addition, cockroaches with pleasure find food in bins, where diseases develop:

• diphtheria;
• dysentery;
• lichen.

In the intestines of insects, eggs of the broad ribbon, as well as eggs of worms, were often found. There have been cases when insects began to feed on the skin of young children. Also, the insect can climb into the ear canal. In this case, it will be necessary to get the pest with the help of doctors.

These insects breed very quickly. They very rarely leave the premises they have chosen on their own. Therefore, for their extermination it is best to use high-quality chemicals or resort to the help of professionals. Only the full treatment of all rooms guarantees their destruction.

Why are home cockroaches dangerous?

Thousands of species, a million-year history and completely unique adaptability - and this is an ordinary cockroach! For three hundred million years, the cockroach successfully inhabited our planet, adapting to various conditions, and it did great for it.

Cockroaches can eat any organics, and even newfangled plastics, only metals and glass are not subject to cockroach jaws.Without water, these insects can last several weeks, although in such conditions, of course, cockroaches will not live long.

In our country, there is not a wide variety of species: a red cockroach won a place in the sun, there is also a black one, it is larger, but red cockroaches, although smaller and weaker, reproduce much faster, and thus prevail over a larger counterpart.

A female red cockroach lays up to fifty eggs at a time, and so on up to five times during her lifetime! The pace of distribution is simply stunning. The female can still carry a cocoon with eggs, and small cockroaches are already gnawing their way out and scattering in search of food!

At first, the cockroaches clog into the deepest crevices, crawling out at night looking for crumbs and water, but after a short time, if you don’t fight them, all lockers, shelves and household appliances will fill up.

The red and black representatives of the cockroach family not only deliver discomfort with the smell of their glands and smear everything around with spots of excrement, they are also carriers of many diseases!

Harm from parasites

Not only the appearance of furniture, tables and utensils spoils the presence of cockroaches, they disrupt the operation of electronic devices, crawling inside and multiplying there, while disabling electronic circuit boards. Whiskered insects are especially attracted by the warmly working appliances, where they will definitely arrange a home.

Only externally cockroaches are shy and harmless, but at night they can eat around the skin on the face of young children, and can crawl into the ear canals, from where they can be obtained only with the help of doctors.

Recently, cockroaches have been accused, and deservedly, of spreading another disease - the "cockroach allergy", which affects millions of people in the United States alone, especially for asthmatics.

Ways to fight

An important condition for the beginning of the fight against "mustachioed" pests, and most importantly, a successful fight is the cleanliness of the room. If the apartment is unsanitary, then the cockroaches will still return, even if they are etched for a while. Insects are attracted to the smell of food, no matter how missing it is, for cockroaches the quality is unprincipled, it would be something to "eat"!

The best measure for the extermination of cockroaches is the disinfection of the premises with the help of professionals. They use complex drugs that act on insects in several ways and are guaranteed to destroy them.

Is cockroach dangerous for humans

Cockroaches are one of the oldest species of animals, insects in particular, living on earth. They find evidence of their existence in the Carboniferous period about 300 million years ago. These insects practically did not change during evolution, cockroaches were able to survive radiation, heat and ice ages.

In our country, more than 60 species of cockroaches are known to take root in these climatic conditions. The most numerous and common household insects are eight species of cockroaches. In total, science has described over 3.5 thousand species.

A cockroach is a thermophilic insect. They settle in mainly in heated buildings. They actively reproduce at any time of the year. They have an excellent reference point in space.Their nests and paths to them are marked with special ferromones.

They are almost omnivorous (they do not eat only glass and metal). Do not disdain spoiled foods and carrion. They can enjoy non-traditional products: wood, pepper, paint, ink, cardboard, leather, etc.

A cockroach is a distributor of over four dozen types of various viruses (causing urinary tract infections, intestinal infections, pathogens of hepatitis, tuberculosis, etc.) as well as worm eggs.

In addition, home cockroaches can provoke allergic reactions and asthma attacks, not only in children, but also in adults. It is worth focusing on the fact that asthma is not caused by a sinatropic insect. After death, the skeleton of the parasite pest remains, which includes chitin.

When mixed, chitin and household dust cause asthma. And the most disgusting and frightening thing, when cockroaches are brought into a dwelling where there are newborns, documented cases where hungry cockroaches ate the edges of the ears, nose, lips of young children!

The most interesting thing about the data of the World Health Organization (WHO) - cockroaches are not spreading agents of infectious diseases. For several decades now, WHO has been trying to prove that a cockroach is not able to transfer any pathogen on its body or inside it.

The unexpected appearance and rapid breeding of synanthropic insects, including cockroaches, usually indicates a low sanitary level. But a completely safe apartment may be at risk.

For example, you can accidentally become neighbors of people who do not consider the cleanliness and hygiene of their body and housing to be the basis, or at least a small part, of their everyday life.

Pets such as cockroaches can also be purchased if the utilities do not conscientiously fulfill their duties - the cellars and attics of the apartment building are not handled efficiently enough.

Upon contact with human food, cockroaches mechanically, i.e. through their physiological organs, waste wastes can spread up to 25 types of all kinds of harmful microbes (acute gastrointestinal diseases, cholera, anthrax, leprosy, plague), as well as up to 12 types of protozoa (bacteria) and helminths (worms).

In the intestines of cockroaches, tuberculosis bacilli remain in their fighting condition for up to nine days, typhoid fever for three days, malignant carbuncle or anthrax (anthrax) for up to 30 days.

In addition, cockroaches can become the spreading and cause of epidemics: poliomyelitis, lymphocytic choriomeningitis, hepatitis.

We buy multimillion-dollar housing in a respectable area of ​​the city, hire a highly paid designer who will create cosiness in a new home for hundreds of thousands of rubles, and we buy expensive furniture made from environmentally friendly materials, safe household appliances. We are ready to pay a lot of money for the maintenance of all this wealth.

But when it comes to extermination of cockroaches, we are sorry to spend a couple of thousand rubles, even if the health of any of their households is at stake.

Important in the fight against cockroaches is the observance of basic hygiene requirements and the adoption of measures that are aimed at:

1. Complete elimination of the places of the shredders (frequent general wet cleaning),
2. Elimination of moisture sources (repair current taps and pipes, do not leave water in irons and temporarily abandon humidifiers),
3. To get rid of various places of shelter in all rooms of the apartment (close up cracks in the floor, walls and ceilings).

All these measures must be “finalized” by professional chemical treatment. In this case, you will forget about the existence of cockroaches for a long time.

Do cockroaches bite

The reason for our hostility to cockroaches is not so simple to explain. The attitude of people to the same ants is much more loyal. A cockroach does not cause significant damage to our products and generally tries to avoid a person. Do cockroaches bite? In rare cases, yes. About the bites of home cockroaches will be discussed in this material.

The cockroach is omnivorous. The oral apparatus of this insect has a complex structure. Powerful jaws (some biologists prefer to call them “lips”) are suited for cracking rough foods.

The upper mandibles are strong plates with teeth. The lower jaw consists of several chitinous “lobes”. In the mouth of the cockroach a kind of tongue. It is also chitinous and solid.

What did not work out in the mouth will be chewed in the stomach. The muscles of the digestive organ of the insect are adapted for this. Therefore, in "hungry" times, a cockroach is able to eat completely inedible things. Such as the:

But in order to attack people, the situation for a cockroach must be extremely extreme. Our "mustachioed neighbor" easily does without food for 40 days.

It is characteristic that cases of cockroach bites are most often recorded on long-range vessels and in student dormitories.

What does a cockroach bite look like? And where does he bite

Despite the powerful jaws, the oral apparatus of the cockroach is relatively small. He can focus human skin only in the most delicate places:

• Lip corners
• Earlobes
• Fingertips
• Eye lids
• Inner thighs

Skin in children, especially in infants, is more vulnerable. There are cases when cockroaches bit off cilia in newborns. But this happens extremely rarely. Young children are very sensitive, adults will certainly come running to their cry, and insects least of all want to show their presence.

Cockroaches are nocturnal. Accordingly, in 99 cases out of 100, cockroaches bite people at night. In a dream, he does not feel anything. Unpleasant sensations will appear in the morning.

The bite site is covered with a crust, around which edema forms. Sometimes quite significant. The wound will itch and burn. Heals a cockroach bite in a few days.

Is a parasite bite dangerous - truth and myths

Cockroach saliva contains tropomyosin - a substance that can provoke an allergic reaction in humans. And the most different - from urticaria to an attack of asthma. Theoretically, cockroach bites can provoke infection, this will happen if bacteria from the legs of the cockroach get into the wound.

Representatives of individual, “wild” species - for example, an Egyptian cockroach, are capable of inflicting more serious wounds on humans. In hot and humid tropics, skin erosion develops at the site of the bite, which is accompanied by the appearance of blisters and ulcers.

They inflict severe pain on a person. And if relatively healthy people recover quickly from bites, in a person with weakened immune systems, ulcers can lead to chronic diseases.

But we must admit: in comparison with other insects - mosquitoes, spiders, fleas, etc. - The cockroach is almost harmless. The reputation of the "mustached neighbor" is seriously spoiled by common myths. Here are just a few of them.

1. Cockroach bites can lead to mutations in the body
2. Cockroach bite causes anaphylactic shock
3. Human skin and hair is a cockroach's favorite treat

The mutation myth was born due to the high resistance of cockroaches to radiation. The maximum permissible dose for a person is 15 times weaker than the one that is harmful to a cockroach. But cockroaches are by no means mutants. On the contrary, the structure of their body formed millions of years ago.

Anaphylactic shock provokes blood-sucking parasites. A cockroach does not feed on blood. He is not a predator at all, preferring to be content with lying badly. But that's not the point.

Allergic reactions in humans occur on toxic substances found in the saliva of wasps, bees and mosquitoes. Cases of anaphylactic shock are recorded infrequently, but always their bites cause severe itching, can be accompanied by lacrimation and shortness of breath.

The myth of the taste preferences of a cockroach has nothing to do with reality. Taste the human beings, the "mustachioed" will decide in the most extreme case. Rotting leftovers from the human table is the cockroach's favorite treat.

How to treat a cockroach bite?

If you become a victim of a domestic cockroach attack, you need to treat the wound with hydrogen peroxide or any other antiseptic. Try to tolerate the itch and not comb the place of the bite - so it will heal faster.

In addition, any combed wound is a potential danger of infection. If a cockroach bite caused an allergic reaction - use an ointment, cream or gel containing an antihistamine.

These measures are suitable for the treatment of any insect bites. Try to determine exactly who bit you, should not only for the sake of curiosity. The strategy for fighting mosquitoes, fleas, cockroaches and other creatures has fundamental differences.

How to deal with a pest

Several methods of extermination of cockroaches. Just transfer all the mustachioed slippers will not work. Cockroaches live in colonies. To achieve the effect, it is necessary to destroy every single one. Here are the main ways:

Insecticides are specially designed toxic substances. Produced in the form of aerosols. They are sprayed throughout the apartment. Trap designs come in a wide variety, from simple cardboard boxes to electrified devices.

At a temperature of -7 ° C, adults die instantly, and at -11 ° C, egg laying also dies. But firstly, to get cold outdoors it should be quite frosty, and secondly, it is dangerous to carry out such a procedure in the apartments of modern residential buildings.

The batteries may burst. So it is best to apply several methods comprehensively at the same time. And from time to time repeat the prophylaxis.

Cockroaches and Prussians at home. What do you need to know?

The most tenacious insects are cockroaches. It is quite difficult to get them out if you suddenly have them. As soon as one cockroach appears, as after a short period of time there are already hordes of them in your house. Around the world there are about 5,000 species of cockroaches.

Reasons for the appearance

You are probably aware, if you have already encountered these insects, that they run too agile. It is difficult to judge why cockroaches appear, because there are quite a few reasons for their appearance. The basis for their appearance may be:

As soon as at least one cockroach gets into your house, most likely there will be a huge number of them and you will ask yourself what the cockroaches came from when “I’m practically always clean.” Although it is not uncommon for cases where completely ambitious families are faced with the problem of cockroaches, which reproduce quite promptly.

Breeding

Any female cockroach is able to produce up to 40 individuals at a time. The number depends on how many cockroaches are in the egg (the sac that the female carries). For her own life, the female can lay 3-4 eggs.

Among other things, cockroaches can leave a mark for other cockroaches, so that it is easier to find water, food or shelter. It is not easy to get rid of these parasites.

Not cheap means give effect not always. First of all, prevention will help prevent cockroaches from appearing in your home. Cockroaches spoil not only food products, but also leather things, book bindings, your plants.

There are cockroaches that live and feed on all kinds of garbage, including feces, and therefore they become carriers of infectious diseases (for example, dysentery and worms).

Life span

There is a legend that cockroaches arose earlier than dinosaurs, surviving at the same time. Vitality, and, accordingly, adaptability - these are the hallmarks of cockroaches. At the same time, in order to live comfortably, they also need certain conditions, including food and moisture.

“Hungry” dark cockroaches are even more dangerous in the apartment. They not only eat their relatives, but also bite people. It has been proven that cockroaches have an excellent memory and, if they lose any part of their body, they lose their ability to learn and are much less oriented in the environment.

Cockroach bites

We have already mentioned that cockroaches can bite people with a lack of food or water. How cockroaches bite:

A cockroach bite is quite capable of causing swelling, as well as skin lesions and irritations. A cockroach can still feed on secretions from our body - saliva, food debris on the body, secretions from the eyes, waste products, and so on.

Allergy to the Prussians

Cockroaches have every chance of causing allergies in people. There are several options for getting cockroaches into our body:

1. inhalation
2. contact
3. with food

Medical statistics show that 60 percent of Americans who have asthma and live in cities have allergies to cockroaches.

A special feature of cockroach waste allergens is the largest, in comparison with other allergens, allergenicity and thermal stability (that is, it is impossible to destroy them even at 100 ° C).

People who are allergic to cockroaches may experience asthma attacks while cleaning in cockroach congestion areas. To protect yourself from allergies to cockroaches, we recommend:

• keep plumbing in working order
• do not leave dirty dishes
• throw away trash on time
• Keep trash containers tightly closed.

These recommendations will help you avoid cockroaches and ultimately protect yourself from allergies and other negative manifestations of the presence of these insects in your home.

Places where they hide

The main danger of coexistence with cockroaches is that they climb into the toilet bowls, garbage cans and other places of accumulation of microbes, which means that they are considered to be their carriers.

We have already mentioned that the breeding of cockroaches is an extremely fast phenomenon. In addition to all this, in their waste products are enzymes that attract other individuals.

How to find

Despite the fact that the bulk of people from represents how cockroaches look, it is not easy to notice them right away. Traditionally, we pay attention to cockroaches, as soon as they are already "in full force" in our apartment, especially in the kitchen. There are indicators by which you can find out where the cockroaches live:

Although most often we do not pay attention to these insignificant indicators, until that time we ourselves will meet with the new inhabitants of our housing.

And when you notice a cockroach, be sure to take measures - inspect all cabinets, corners, among other things, in the place where the cockroach was discovered, it is preferable to wash the dishes, inspect the products.

How to get rid of pests

For a long time, humanity has been troubled by the successful fight against cockroaches, which are considered annoying and harmful neighbors in the home. In addition to the fact that they are able to be carriers of various diseases, there are people who are terrified by the exclusively external appearance of this insect. The fight against domestic cockroaches is carried out a long time ago.

From this point of view, the fight against cockroaches on the living space, on the one hand, is contrary to the normal development of the bioworld, on the other hand, insects are unsafe, as they are considered to be the distributors of parasitic worms and all kinds of microbes.

Microbes, the carriers of which are cockroaches, can cause cholera, typhoid, tuberculosis, dysentery and other diseases. Below you can see photos of cockroaches.

When you found cockroaches, you should quickly make the most of efforts to remove them. Misses in the attempts to bring out these insects often only lead to the fact that they seem to become smaller, but then they multiply very quickly.

As soon as you led everyone out (actually, this happens infrequently), they all have the same chance to run over again from unscrupulous neighbors. Those owners who take part in this “war” reach the point that they begin to kill cockroaches in a dream.

What harm can cockroaches do?

It is a common misconception that there is no great harm from domestic cockroaches except that these parasites are unpleasant. Nevertheless, for all the harm to human health caused by cockroaches, there is even a separate name - blattopterosis.

The harm from cockroaches in the house can be divided into three categories:

Harm to human health

Cockroaches can seriously harm human health in several ways:

1. mechanically spread the infection;
2. biting and biting the epidermis;
3. as a foreign body;
4. allergic reaction.

Parasite bites

They really bite. When they do not have access to food and water, angry parasites are most dangerous: they begin to attack people when they sleep. They bite people and gnaw skin from the lips and around the nails and eyes.

They can gnaw on the skin also in the nasolabial triangle of a small child, gnaw on ears and eyelashes, bite on corns. For children, cockroaches are most dangerous. It doesn’t matter what kind of cockroaches you have, whether the Prussians or the black ones, anyone can start biting.

Cockroach bites look like reddened sore spots on the skin. In the wounds that form from bites, infection can get, infection can occur.

The skin after this crusts and heals for a very long time. Prusak bites are also painful. In red and black cockroaches living in the house, the mouth apparatus is perfectly adapted for bites and nibbling.

They can look for food debris on the human body, absorb saliva and eat feces. There is nothing pleasant about this, and if the bite is also launched and not processed, the consequences will have to struggle for a long time.

Cockroach Allergy

Home cockroaches are also dangerous because they cause allergies: allergens most likely get into food that the cockroach crawled into or somehow got into. Waste of parasites can get in the airborne droplets, cockroach bite can also cause allergies.

If you are allergic to cockroaches, the following symptoms will help to understand this:

• runny nose, nasal congestion;
• coughing, sneezing;
• eye irritation, tearing;
• skin rashes.

An allergic reaction to cockroaches in the house can lead a person to asthmatic manifestations or exacerbation of existing asthma.

Infection transfer

Home cockroaches are mechanical carriers of various infections, the causes of the spread of dangerous diseases. They crawl along garbage, sewers, there is nothing forbidden for them in the most disgusting places of buildings. They can eat excrement, including sick people.

In addition to them, they carry additional parasites, for example, worm eggs. Human infection can occur:

Foreign body

There are frequent cases when a cockroach enters the human body. They creep into the ear, can pass through the nose or mouth while a person is sleeping, or even swallowed with food. Most often, doctors are treated with the problem that a red or black cockroach crawled into the auricle.

Once in the ear, the cockroach cannot get out in the same way that it climbed. It will move, cross and damage the eardrum, causing severe pain to the person. A cockroach in the ear can cause infection.

If a cockroach crawled into your ear, you can understand this by pain. When there is no way to immediately consult a doctor, you can pull it out of your ear yourself. To do if the parasite crawled, you need the following:

1. The person calms down and fits so that the ear with the insect is on top.
2. The ear is slowly filled with vegetable or baby oil. Oil poured into the ear should be held until the cockroach stops moving, and also after a couple of minutes after that.
3. The oil is drained, the ear is washed with warm water until the dead insect is outside.

After self-extraction, you should also go to the doctor and check whether there are any insect particles inside the ear. A cockroach can also get into the nose, causing a runny nose and pain.

Physical and aesthetic discomfort

The discomfort that some people feel when they see Prusaks or black cockroaches next to them can cause a lot of stress, leading to tantrums.

Whatever species settles in your house, the fight against cockroaches should begin as soon as possible. They can cause colossal harm to health.

White cockroaches in the apartment - is it dangerous?

A white cockroach is a rather rare case, to see it means to catch a cockroach by surprise, in this article we will talk in detail about white cockroaches and how they (except for color) differ from black or red relatives. Of course, he is a cockroach in Africa as well, in its behavior, habits and lifestyle, a white cockroach is no different from the usual one.

A white cockroach does not have any super abilities or privileges, and as a rule a white cockroach usually becomes white.

There are only three assumptions about how a simple cockroach can turn white: it is a molt (when a cockroach drops its old chitinous coating and for a while it will be white or almost transparent).

Another option in which a cockroach can turn white is poisoning with chlorine-containing insecticides, it is quite possible that the cockroach ate poison and the chemical reaction of chlorine on its body smoothly turns it into a dead man.

The chitin layer of the cockroach, as it turned out, is influenced by various chemicals, and it is chlorine that can stain the cockroach in white. If you see a white cockroach - it is quite possible that he will die soon.

Immediately we hasten to reassure you, as they wrote above and in other articles, a white cockroach differs from a Prusak or a black cockroach only in color, it is quite possible that the cockroach will finish its molt and become colored again.

Cockroaches usually moult in secluded places, where they discard their old chitinous layer, which, over time, you will sweep out and throw it in the trash.

No matter how disgusting it sounds, but it's true. In any case, a white cockroach poses the same threat as any other. He is the same breeding ground for diseases, dirt and parasites.

Next, you should study the means of cockroaches, choose the best option and use it according to the instructions. Everything is quite simple, but it requires active measures, iron nerves and time.

Why are Prussians dangerous to humans?

Are cockroaches dangerous for people? These ubiquitous boogers can really cause harm, as they are carriers of intestinal and skin infections, tuberculosis, hepatitis ... On their feet they spread eggs of worms, and, in contact with food, can "share" parasites with humans.

Today, domestic parasites have ceased to be a global problem: now colonies of malicious insects are not found in every apartment. There is an opinion that hygiene helped to defeat the cockroach.

Adherents of this theory are very fond of bringing a hackneyed argument: “But I do wet cleaning twice a day - and no parasites!” But this is only partially true. Yes, cockroaches really love unsanitary conditions, deposits of old rubbish, food waste not thrown away on time ... however, perfect cleanliness in the home does not guarantee the absence of insects.

If there is at least one “dysfunctional” apartment inhabited by cockroaches at the entrance, pests will go to the neighbors to visit through ventilation shafts and slots invisible to the human eye in walls, floors, and ceilings.

What is more dangerous for cockroaches for humans - they cause allergies in many people. Chitin of insects, having lain in a secluded corner for a couple of months, crumbles into caustic dust and causes irritation of the nasopharynx in all who breathe it.

And this is eternal snot, sneezing, asphyxiation, even conjunctivitis ... What is allergic to do in the face of a cockroach threat? If the processing of your own apartment with pesticides did not give the expected result, you need to raise the public and poison the parasites with the whole entrance. Yes, it is very troublesome.

Yes, it will be difficult to reach many neighbors (both literally and figuratively). Yes, you probably have to take all the costs for yourself. But selling an “allergic” apartment and looking for a new place of residence will be even more expensive. And which is characteristic, even more troublesome.

A few words directly about pesticides. For insects, they are deadly, but not for humans - however, you definitely should not touch them with your bare hands, breathe them, or let children or pets in them, because even accidental and fleeting contact with poison can be dangerous.

The following technology is usually used at home: the poison is sprayed with a special device, and it, like fog, spreads across the floor, penetrates every crack and every crack, giving insects no chance to sit out the gas attack in their favorite shelters.

After the execution, the room is well ventilated - and again it is suitable for living. For the lives of people, of course - but the parasites will not pass!
