Why do some bugs bite while others do not, and how to avoid the consequences?

Hello! During the time of my marriage, we faced one delicate problem: we got bed bugs. But the victim was not me, but my husband.

At first, I did not even believe him. They bit his bedbugs. For this reason alone, we calculated the parasites.

It was a bit surprising, because they slept all the time together. Then they explained to me the possible reasons. Want to know why some bugs bite, but not others? What could cause this situation? I will try to paint everything in detail now.

Why are bedbugs not biting everyone?

The individual smell of a person or the difference in blood group has nothing to do with it. Just because of the specifics of the device of the oral apparatus and the technique of bites, the bug selects a person with thin skin.

The bug, in search of the blood vessel itself, can make a few prokusi of thin skin. However, bedbugs can also bite people with thick skin.

However, due to the low sensitivity of the skin and higher resistance to the irritating property of saliva, such people simply do not feel the effects of bites. According to research, about 65-70% of their victims do not feel bite bites, which prevents them from being detected on time.

Why do bedbugs stink?

With severe infection of the room, a characteristic bug smell appears in it: sugary and tart, vaguely reminiscent of almonds or rotted raspberries. Connoisseurs and connoisseurs of elite cognac compare the smell of aged cognac with the smell of bugs.

The presence of odorous glands in the insect explains why the bugs smell. Iron secrete a substance whose purpose for the insect is not fully understood. Presumably, this smell plays a role in the reproduction of parasites, serves to protect against numerous enemies (cockroaches, ants, ticks, spiders).

How long do their bites go

It is worth getting to know an unpleasant neighbor - a home bug. We recognize the enemy in person. Sizes: 3 to 8 mm, depending on blood saturation.

By the color of the bug you can determine when he was last eating. The scarlet parasite has consumed blood recently. The black insect has managed to get hungry and will soon go on a night hunt.

The first serves to inject saliva, which anesthetizes the effect, the second channel is designed to absorb blood. The insect pierces the body and gropes the nearest blood vessel with its proboscis.

Due to anesthesia, the bite is not felt, so it is almost impossible to catch the parasite.

Bite symptoms

A person with sensitive skin usually notices the following signs indicating that the couch or bed is infected with bloodsucking parasites:

Not only adults can bite, but also larvae of bugs. Moreover, if an adult bug eats once every 5-7 days, then the larva should receive blood daily, with a bite it does not inject saliva, and such a bite will be painful.

The consequences of an insect invasion

The individual characteristics of the human body determine how long the bedbugs take. Methods of how to drive the bugs yourself. This is influenced by the strength of the immune system, a tendency to allergic reactions, the characteristic of the skin.

For one, a severe allergy is characteristic with bite marks that go away for 5-7 days, a person with less sensitive skin may experience discomfort during the day. When long chains of multiple bites last for weeks, you should consult a dermatologist or use folk remedies. It is advisable to use antihistamines.

The most unpleasant consequence of a bug bite (how to spread from bedbugs) can be infection of scratching bite sites (with unbearable itching).

It is not conclusively confirmed, but there is an assumption that bed bugs can tolerate tuberculosis, smallpox, hepatitis B, tularemia and other dangerous diseases.

It is proved precisely: in the products of the vital activity of insects, rickettsia - microscopic intracellular parasites from the category of bacteria can be contained.

Do animal parasites bite?

Preferred by the bug is the object of reliable human nutrition: 98% of the total volume of blood consumed by the bug is human blood.

Homeowners where bugs are found are eager to find out: are bedbugs biting cats, dogs, and other animals?

Most animals have thick hair, which makes it difficult to get to the skin, and sometimes makes it simply impossible. Even if the bug also manages to get on the wool, getting to the power source will not be easy.

The skin of animals is thick and dense with an abundance of sebaceous glands, it is extremely difficult to bite through. This can be the power of an adult and very hungry individual with an unusually powerful jaw apparatus.

The active life of most pets falls during the night. In addition, they have well-developed sensory organs that are ten times higher than these indicators in humans, and the bug will certainly be noticed and destroyed in time.

If we consider the relationship of bugs and animals, there is another danger. A homeless cat or dog, whom a person warmed by kindness of soul, can easily bring dangerous insects to the house.

When a person decides on an act of mercy, the poor fellow from the garbage dump should immediately be washed with antiparasitic shampoo and treated with auricles.

How to get rid of bedbugs

Complete extermination of insects is a difficult task. You can try folk methods, with a slight infection with bugs.

If the infection is widespread, it is better to contact the sanitary-epidemiological station (SES) or commercial disinfestation companies. Only in this case a successful disinsection of the premises is guaranteed.

Magnolika1965. Once this infection has wound up, you won’t get rid of it to the end. It’s better for the sofa to say “goodbye” - and to dump it. In the apartment after the damage, and better with the SES - they are specialists in this, you will have to make a concrete repair - otherwise they will climb again.

Ivan Vasilievich. And here’s what just amazes me: no matter how bad it may be, it’s so unbelievably tenacious, with such adaptive data: they fall into suspended animation for 200 years, and their tails grow new, and they don’t have any changes from +50 to -50 . Well, why is a person wrong? And we are ill forever, and freeze.

SELFIC. We bought a corner from our hands. About two weeks later I noticed all kinds of dots on me, like sores, with redness. And let them itch with blisters. The husband is okay. No symptoms.

Then in the morning she somehow noticed on a sheet crushed. Contacted the SES, left for three days. The stench then stood utterly, as they entered. Things were mulled, rubbed and washed all around. Not yet 3 months. What will happen next, let's see ...

Kostyan. These vampires can hibernate. Then wake up as the right moment appears. Their eggs are kept for 3 months. No need to buy any sofas, and type apartments with furniture.

I wonder if there are any companies that come to the house, sofas and the whole apartment is treated for prevention? Hot steam, for example.

Mashulka. Our daughter is an asthmatic. They drove to a sanatorium, to doctors, treated. Remission. We moved to a new apartment, and there - bugs. As if the owners are decent people, the apartment is not renovated, but the finish is good three years ago.

Bed one and a half, by the way, left. As the aggravation began at the daughter, nothing really helped. As bedbugs noticed, the doctor was told. He says bugs can affect this: they emit some kind of aggressive smell. Now we moved to a rented apartment. First, let's fix it, then the repair is complete.

Why some bugs in the family do not bite?


The opinion that bedbugs do not bite everyone in the family is a fallacy. Bed bugs bite all people indoors, and their selectivity is actually apparent. The impression that some people bite these parasites, but not others, can develop for the following reasons:

• According to statistics, about 70% of people do not feel bedbug bites at all, they have no consequences of bites, allergic reactions do not occur. Moreover, both women and men can be so insensitive. If a person sleeps in one room, sharply reacting to parasite bites, and a person who does not feel them, bedbugs bite them both, but the next morning the first one will itch and smear the red bumps with various ointments, and the second will not find anything on his body. It will seem as if insects have bitten only one person and not touched another;
• Bedbugs are difficult to attack and bite a person covered with a blanket or sleeping in pajamas. They prefer to bite open areas of the skin, and therefore a person sleeping without clothes and a blanket will be bitten by a greater number of insects than sheltered. As a result, due to the small number of bites, a person from under the covers may not be able to find them, and the second will be strewn with red dots;
• Similarly, bedbugs are difficult to move around areas of the body covered with hair.Therefore, people with a small amount of hair (more often women and children) are more likely to be hocused than some men with developed hair on their back and legs.

However, the last two reasons are not as significant as the first. It almost always seems that bugs do not bite everyone, just because some people do not feel their bites, do not suffer from them and do not pay attention to them.

These assumptions are not experimentally disproved, but with a high probability they are erroneous: bugs when searching for a victim are not guided by the smell of blood, but by the smell of carbon dioxide emitted by humans (even carbon dioxide traps for them are based on this principle), and therefore they cannot know in advance which this or that person will have skin.

Someone is sure that bedbugs selectively bite people with certain blood groups or a Rh factor. This is also a mistake: experimentally, according to surveys of dermatovenerologists in the United States, it was found that bedbugs bite at about the same frequency of people with all blood types.

Purely hypothetically, a situation may arise when bedbugs for the most part bite one person indoors, but do not bite another.

It is clear that they bite it, and the second sleeping person may not be bitten at all. But this situation rarely arises: bed bugs most often hide in the mattresses of the bed, and it is almost equally easy for them to get to both victims.

Why are bed bugs not biting all people in the family?

Often people who have become those "lucky ones" who have got bed bugs have many questions: How to destroy them, where did they come from, where are they hiding in the apartment, do they tolerate infections and diseases, and so on ... Very often they ask about why bugs do not bite all people ?!

But after a certain time, the traces disappear if they are not scratched. And the rest of the residents wake up completely unscathed. This often happens even in people sleeping together - one with red tubercles, and the second - clean and slept.

Why are bedbugs not biting everyone ?!

Since parasites bite in the dark, it is very difficult to detect them during the day, in most cases, residents do not even suspect the existence of bugs in the apartment. In daylight, they hide in their shelters, multiply and digest the food drunk that night.

Their hunt begins from 3 to 5 in the morning, when a person is sleeping soundly. Therefore, bites can partially disappear upon waking in the morning.

There is an assumption that parasites carefully choose their victim. Only bite people who have the first or second blood group, by age and gender, but not others. But since there are much more people with the first and second groups in the world than the rest, there will also be more bitten people.

In fact, home bugs drink any human blood. Their choice depends only on how easy it is to get to it.

Parasites have a special nutritional organ, which consists of two jaws. The upper one contains a tubule through which an anesthetic is injected into the victim, the lower one pierces the skin and searches for small capillaries.

That is why the victim’s skin must be soft and delicate so that it can easily get to the blood.They leave several bites in a straight line on the body because they are looking for a better place.

Of course, if the family does not live in the apartment, but only one man, the bugs will not pick and choose. Just a person will not notice small bites due to dense skin, they will not be so pronounced to remind themselves.

In children, bite symptoms appear the same as in parents. But due to the high tenderness and softness, the skin swells faster and passes more difficult.

The main thing is that you can not give children scratching bites, because in this way you can bring the infection into the wounds.

An allergic reaction may occur, in some people the red swelling will disappear in a short time, and the rest will have to wait a few days.

Features of victim selection

There are several more reasons why bedbugs do not bite all people:

Therefore, we can conclude that bedbugs bite only one person not because of blood type, age and gender. They only feel the smell of blood; pests go to that smell. If the victim’s skin is thinner, more tender, then this very fragrance will be much better felt, attracting parasites.

What to do if still bit?

After an attack of pests, it is better to lie in a warm bath, and then treat the wounds with alcohol or decoctions of herbs. Special ointments and lotions are also sold for these purposes. And when allergies to bedbug saliva appear, it is necessary to purchase antihistamines.

If the wounds are too inflamed, or pus appears, it means that they are infected, it is best to consult a doctor.

Bodily harm

Bed bugs are blood-sucking parasites, there is a risk that they are possible carriers of various serious diseases. But there is no evidence for this. This is explained by the fact that the proboscis of the pests is divided into two jaws, the blood cannot be infected, because it passes through only one tubule. But taking risks is still not worth it.

If you take a chance and tighten with this matter, in a few weeks the housing will turn into a bedbug, at night no one will be able to sleep.

Why some bugs bite, but not others

It has long been noticed that bedbugs bite certain people. There was even a theory that they choose a victim according to the blood group: supposedly the first and second groups are suitable for these insects.

In fact, it’s just a version that was subsequently refuted.

Who falls into the "risk group"

So who can fall prey to this insatiable insect? To explain why some bugs bite while others do not, it turned out to be much simpler than it seemed: the parasite is attracted to the person by the smell of carbon dioxide released during exhalation, as well as the smell of blood, which the bugs feel very well.

But here, everything is not so smooth: if several people with different smells are present in the house, the one who has thinner skin will be the first victim.

Bed bugs - women and children

In the family, children and women suffer most from bite bugs, since their skin is soft and smooth. The insect does not need much effort to pierce such covers with a proboscis.

The situation is different with men: the skin is harder, therefore it does not lend itself well to the not particularly strong proboscis of the bug, and if it succeeds in piercing, then the sensitivity is not so strong as to cause irritation, as in children and women.

The peculiarity of the “hunting” of bugs is that the insect does not saturate in one bite, so it has to make about five punctures.

After this, the parasite leaves for shelter and does not bother the residents for about five days, but you should not think that you will live peacefully for almost a week, because in one house there can be up to five hundred individuals who will drink blood every now and then.

The risk of being bitten increases if you go to bed without pajamas: by morning all exposed body surfaces will be bitten.

If you became a “victim” of an insect, remember the main rule: bites should not be combed so as not to catch the infection. Treat with an asterisk, rescuer, or soda solution to remove itching and pain.

Why do some bugs bite others but not?

Bed bugs are insects from which even the cleanest owner cannot be insured. Why are bedbugs biting some people and not others? After all, a person can be considered food for bloodsucking insects. But at the same time, some wake up bitten, others without traces of defeat.

Is there a preference for bloodsuckers

There is an opinion that pests bite someone, but do not pay any attention to someone. But this is far from the case. These insects feed only on blood. To get it, they are forced to bite sleeping people. Why are bedbugs not biting all people? This is because they have their own preferences.

The next victims on this list are children. The lower their age, the more likely they are to be among the victims. The skin of the babies is thin and delicate, this facilitates the work of insects in finding food. The next object may be the skin of women.

It is not as thin as in children, but not coarse. Bedbugs through the skin feel very good smell of blood. Men are bitten by bloodsuckers much less often. Therefore, it seems that they can affect only children or women.

So, the following categories of population are attacked by bedbugs:

• Loving to sleep without pajama suits;
• sleeping without blankets;
• children;
• women.

Blood type is completely not important to insects.

Danger of bedbugs and their bites

A bed insect bite is very easy to spot. A path of red spots remains on the skin. The affected area of ​​the skin itches. But combing this place is not recommended, so as not to bring the infection into the wound. The latter will bring even more pain and cause inflammation.

You can reduce inflammation by taking certain antihistamines. For this purpose, quite suitable: Diazolin, Diphenhydramine, Suprastin. But before taking them, it is better to consult a doctor.When choosing a place to sleep, you need to carefully inspect the room, bed. This is especially recommended in budget hotels.

After a night's sleep, some may find chains of swelling on themselves. These are the bites of bed bugs. They hurt and itch. If you do not touch them, then very quickly they disappear from the skin. Bed bugs conduct their active actions in finding food between 3 and 5 o’clock in the morning. The rest of the time they hide and digest the drunk blood.

Who does the bug bite? What kind of blood does he like and choose? These questions can be answered very simply: bedbugs are primarily people with thin skin. These are usually children and women. Bedbugs can attack the victim in groups.

Some men with thick and rough skin are practically not afraid of bites. They simply do not feel pain from small wounds.

Some believe that blood of the 1st and 2nd groups is especially fond of bugs. But so many people have such blood, which is why a certain opinion was created. In fact, the insect smells blood through thin skin and crawls on it.

Bedbugs cannot be saturated with one bite, therefore they create a whole path of 5-7 bites. Then for almost a week the bug will not bother anyone. But in the house there are always several hundred individuals who are able to bite you any night.

How do bed bugs choose a victim?

For those who have encountered bed bugs in everyday life, the question often arises: why do bedbugs bite some members of the family and others bypass?

Klopov attracts:

1. body odour;
2. body heat;
3. carbon dioxide exhaled by man.

Substances

According to the assurances of scientists, bedbugs are attracted by five volatile substances (odors): four aldehydes and ketone. At the same time, insects react only to small concentrations of volatile substances, strong odors repel them, cleanly washed skin also does not attract them.

The attractiveness of the smell of sweat for bedbugs depends on the stage of its disintegration; experiments have shown that “sebum” and ear wax turned out to be the most attractive.

Multiple experiments by experts from different countries have allowed us to determine that bedbugs determine their prey by body odor, exhaled carbon dioxide and the heat released. For catching odors, bugs have special receptors located on antennae - antennae.

Ketones and several aldehydes (heptanal, octanal, nonanal and decanal), which are secreted by all people and animals on the planet, feel bugs best of all. It turns out that bugs just to drink blood, better than human, but you can get by with animals.

The concentration of substances in the smell is a determining factor in the choice of the victim. Whoever has more aldehydes in his blood will be more attractive to the bug. This explains why some people are bugged more by bugs than others (it all depends on the ratio of ketone and aldehydes in the smell of the victim).

Trying to disguise yourself or hide from bedbugs is useless: you have to kill too many traces of your life so that bedbugs do not recognize your lunch in you. It is much better to order professional removal of bugs and forget about parasites in a few days.

Bedbugs may not bite everyone in the house

In the middle of the night or in the morning, looking at oneself and a person sleeping nearby, sometimes the question arises: why are bedbugs not biting everyone in the house? It can be seen: they bite some members of the family, while others do not exist at all.

Why is insects so selective?

Age does not matter

Usually in a family that sleeps in the same room, bites are most often observed in children. And many people conclude: young blood attracts insects much more. But is it really so?

Insects bite the sleeping baby and will not touch the rest. But this happens only in rare cases. Usually, pests regale themselves by all family members, just the reaction of the body in some is almost invisible.

There is also another option, why only a child suffers. After all, he sleeps in a separate bed. When bed bugs live in it, then they may not move to adults.

The only thing is true: for children, damage from insects is dangerous. Their immunity is not so formed that they can fight the infections that parasites carry. Often there are allergic reactions.

Also, at a young age, the places of bites are often combed, from which side effects are also possible.

In fact, for bloodsuckers age does not matter. Both adults and children are at risk, but the difference is in the degree of tolerance of the consequences.

Does the gender of the victim matter

It is noted: if bedbugs bite only one person, then this is usually a woman.

But such behavior is not connected at all with more delicious blood or the smell is much more pleasant than the male one. Insects do not distinguish between sexual characteristics. Just a man’s skin is often thicker and easier to damage.

If a large number of bloodsuckers divorced at home, they pierce any cover in order to save their lives. But preference is given to thin and smooth skin.

Scientists explain the following: through the delicate epidermis, the smell of blood is more easily captured, and its parasites are found faster and easier.

Perhaps the reason why the choice falls on girls is commonplace: they do not have as much hair as on a male body. Pests are easier to move around.

Alena, 28 years old: “This morning I found a path from bites on me, I realized: we got bugs. They examined her husband, he also has characteristic signs, but they are not so noticeable, and he is not disturbed at all. Everything about me is accompanied by incredible itching and redness. ”

Is it better to sleep dressed?

Home bugs that live on the couch prefer to bite an open person. It's hard for them to get under the covers, pajamas. So they attack more often on open areas of the body.

This is another explanation why children are more susceptible to damage: during sleep they sleep chaotically, throw off their blankets, do not like pajamas, as a result becoming easy prey.

As a result, bedbugs live in mattresses and beds for a long time, until the population grows to such sizes when they simply cannot be overlooked. But to remove them in such cases, it becomes difficult without the services of pest control.

Does blood type play a role

Some people pay attention to the blood group, mistakenly believing that bedbugs choose their victim from the first or second.

There was no scientific confirmation of this. Polls show that insects bite everyone the same way. Just representatives of the third and fourth groups less than the rest.

Bed bugs love blood, and which group doesn’t matter. It’s just that some people are more accessible, while others are not.

Interesting: some studies have shown alcohol unacceptability. A female who feasted on a drunk man refuses to lay eggs. As a result, bloodsuckers refuse such a "treat".

By the way, there are reptiles distinguishing the presence of alcohol in the body also by smell. It is released in small amounts through the epidermis. But as long as there is no other source of food nearby, one has to be content with this.

Who the bugs do not bite?

As it turned out, everyone has a risk of being bitten.It is recommended that you take precautions to help protect yourself from insects.

And the location of the bed does not matter. Parasites hide under the mattress, in the upholstery of the sofa, in pillows. They easily reach the victims and choose any, and not the one to which they come first.

In order to protect against the appearance of parasites

First of all, they should block the path of their penetration. In apartment buildings, these are sockets, ventilation holes, cracks and crevices in the walls, ceilings and floors, windows and doors. It is recommended to seal them with cement, nets, rubber seals.

Carefully inspect household appliances and furniture for insect nests. You can completely get rid of them only if a nursery is found.

When washing the bedding, add a few drops of tea tree essential oil. Adults will hasten to find other housing, and you can bring out bugs when they are still wound up.

Before going to bed, use a lavender scent shower gel. Or just rub the grass ether into the skin. The parasite will not bite for such a skin. The advantage of the method: the person acts soothingly. Relieves irritability and headache.

You can use chemicals in case the family grows. Plants and essential oils are used only as repellents, as repel adult insects, but do not affect eggs.

What determines the selectivity

Bedbugs bite some, but not others. Pests have their own preferences. Less likely to suffer from bites of bloodsucking men, owners of the first and second blood groups are more often attacked.

Victim definition

The only food source for parasites is blood. In their activities, insects are guided by smells. They subtly smell aromas, they themselves possess odorous glands.

The victim is found by insects using carbon dioxide, which is released by a sleeping person with breathing. If the room is crowded, the parasites begin to sort out with bites. Then a situation arises that only one person bites, or not everyone in the family bites.

Lifestyle

The "bed-lodgers" hide in the nests during the day, because they cannot tolerate the sun's rays. They activate activity with the onset of darkness, when everyone is sleeping, they do not see what is happening around. They bite only at night, or closer to the morning. Biting go in the interval between 3 a.m. and 8 a.m.

At the initial stage of infection, there are bed bugs, but they do not bite. The adult has enough food reserves for a maximum of 10 days. Coming to a new place of residence, the female develops the territory, chooses a place for the nest, lays eggs.

And only after some time creeps into the human body. The first evidence of the presence of a parasitic fauna appears, but several bites on the body do not always attract the proper attention of a person.

It is interesting to know who the bugs bite, because the statement is often found - they only bite me, but they do not bother everyone else. Why bugs do not bite, why, the explanation is very simple.

"Bloodsuckers" find a person by the smell of carbon dioxide. Stronger blood is felt in people with thin skin, where the vessels are located closer to the surface. Therefore, bedbugs often bite children. Bites remain on any part of the body, even on the face.

If there are no children in the house, more women bite. The skin of the fair sex is somewhat thinner than men. Getting to the vessels is much easier.Bites remain on the neck, shoulders, back, legs, arms.

The question - what blood type do bed bugs like, also sounds often. How and which blood group do not bite bloodsuckers. There is no consensus on this. Experts say that the insect does not make any difference what kind of blood flows through the veins. Eyewitnesses say they are annoying bugs to people with the second group, the first.

Owners of groups 3 and 4 practically do not suffer from bites of bed parasites. However, in a situation where the question is not for life, for death, such a separation does not play a role.

To scare off an insect for a while, prevent bites can be a fragrant remedy - perfume, cream, gel. Then the situation is that a man is chosen as a victim more often than women.
