How to treat bedbug bites on the human body - pharmacy drugs and folk remedies

Good day. Somehow they sent me on a business trip. I was not alone, but with a colleague. We had to spend the night in a rented apartment, which we found whipped up.

I slept in the hall, there were no incidents with me, but my partner was less fortunate.

Bedbugs bit her in the bedroom. Very much bitten. Multiple tracks only confirmed this. I had to save a colleague from unbearable itching. Want to know how to treat bedbug bites on a person’s body? What tools are better to use? In the article below I will describe all the details.

Bed Bugs

Bed bugs are a blood-sucking insect, has a flattened oval body shape from 3 to 8 mm long. The color and size of bugs depends on their age and degree of saturation with blood. The adult is light brown to brown in color.

Unfortunately, in our time, no one is safe from the appearance of such extremely unpleasant insects, like bed bugs. Stereotypes that these insects appear only in unsanitary conditions have long been in the past.

At the moment, the connection between the bites of bedbugs and infection through a bite of various diseases is not found. Nevertheless, bedbugs coolly poison our lives, interfering with restful sleep, thereby reducing performance.

What do parasite bites look like?

Every year the number of people suffering from the bites of these parasites is growing. If after awakening you notice a lot of round red swelling on your body, do not rush to refer to a mosquito bite, perhaps parasites called “bugs” have come to your house.

The difference between bug bites and an allergic reaction. In most cases, bug bites are misdiagnosed, such as scabies or allergies to something. But there are significant differences between a bed bug bite and an allergic reaction.

1. The redness from the bite is not continuous, it is located by the track.
2. An allergic rash is spread over the entire surface of the body, and not in any separate open areas.
3. The bite mark, as a rule, does not change over time, the size, color and shape of the rash from allergies can change quite quickly.
4. Other family members did not notice anything suspicious on their skin, unlike the victim.

The left photo depicts an allergic reaction, on the right bites of a bug.

The difference between bug bites and other insect bites, such as mosquitoes, fleas, etc.. To distinguish a bug bite from other insect bites is somewhat more difficult, since all bites look about the same - a red spot accompanied by an itch.

The pain from a midge bite is stronger, and the wound from a bite is less, with a drop of caked blood in the middle. Bites of large insects (bees, hornets, wasps) are always remembered by a person because of acute pain. Bedbugs bite unnoticed and the bite can be found after some time.

Bite symptoms

Bedbugs mainly bite open areas of the body: legs, arms, neck, face, shoulders. The bite itself can manifest itself in every person in different ways.

As a rule, the main symptoms of a bed bug bite include severe redness, rounded swelling, and strong and irritable itching. Unlike mosquito bites, bedbugs are more painful and more clearly defined. In some cases, an allergic reaction is possible, but this is rare.

Stains from a bed bug bite are a reaction to the saliva that a bug releases before a bite so that the blood is better prepared for intake. Because of this, the trace from a bite of a bed bug remains longer than from a bite of other insects.

Interestingly, if you are bitten by an adult bug, then the reaction can not immediately be seen. If it is young, then most likely the reaction will not take long - it will appear instantly. This is due to the fact that young bugs, unlike adults, are not able to secrete saliva, which contains a substance that acts as an anesthetic.

So, to summarize, the symptoms of bedbug bites are as follows:

• Redness
• Itching
• Swelling
• Grouped bites (3 - 5 punctures of the skin at a distance of 2 - 4 centimeters from each other).

Also, bugs are characterized by a special smell, because they have odorous glands, the openings of which are located in adults on the chest, and in larvae on the abdomen. If you crush the bug, which in principle is very difficult, you can smell their specific smell.

By the way, opinions differ on the smell: some people think that bedbugs smell like something sweet, like spoiled raspberries, others say that brandy, others say that the room with bedbugs smells like almonds.

When and whom do they bite first?

It is known that the activity of these parasites is concentrated in the night and early morning hours, i.e. in the dark, when a person sleeps especially soundly.

Sensations from bites of bed bugs are often subjective and individual. So, for example, most often women and children complain about bites. Their skin is thinner and softer, therefore, the vessels are closer, which attracts the bug.

Adult men are less sensitive to bites, and sometimes they may not even notice them. Rumors that bedbugs bite people selectively, and even more so carriers of certain blood groups, are erroneous. Bed bugs bite everyone, but the reaction to a bite is different for all people. So, there is no connection between the frequency of bedbug bites and a person’s blood type.

How to bite bloodsuckers?

Any blood-sucking insect has its own nutritional characteristics. Bed bugs are no exception. There are many specific details about how to bite bugs.

But back to how the bug bites. As already mentioned above, in the proboscis of the bug there are two channels that allow it to eat and even go unpunished for some time. One channel - for the absorption of blood of the victim, the second - for the introduction of saliva into the bite, which contains a substance that plays the role of pain medication.

The length of the proboscis of a bed bug does not exceed 0.7 mm, this makes him look for areas of the skin with the closest blood vessels located in which blood can be drawn. For one bite, the bug sucks 1-1.5 μl of blood.

After receiving this portion, the parasite moves 2-4 centimeters across the body and bites again. In young animals, a bite, as a rule, takes about 2-3 minutes, in adults of a bed bug this time can last up to 15 minutes.

But a lot depends on the amount of these insects in the room. If the territory is densely populated by these parasites, then in the morning a person can count up to 500 bites on his body!

What is a bug bite dangerous?

The most dangerous consequence of a bed bug bite is a possible allergic reaction. In history, there are cases when people who are especially sensitive to the enzymes that the bug secretes, the bite provoked anaphylactic shock.

Severe allergic reactions are very dangerous for humans, in addition to anaphylactic shock, they can cause:

• Skin erosion;
• Strong swelling in the bite area;
• Difficulty breathing (muscle cramps in the bronchi);
• Hyperemia (overflow of blood vessels in the bite area);
• Sometimes nausea, fainting.

But these cases are single. Basically, a bug bite is not more dangerous than a mosquito bite. As mentioned above, bedbugs are not carriers of infections that are dangerous to human life.

Some people may have a long lasting rash. However, more often, insects crawling on the bed can cause psychological disorders and fear of falling asleep. Due to the inability to rest calmly, people's working capacity decreases, their general health worsens, and nervousness and irritability increase.

Also, bites can not heal for a long time and after a while begin to fester. Most likely, this is a sign that an infection got into the wound when combing. In this case, it is advisable to consult a doctor.

In general, when bites are found on the body, one should not panic, but measures to destroy parasites must be taken immediately.

How to protect yourself from bites

Somehow to prevent the bites of bed bugs is almost impossible. The best way to get rid of the bites of these parasites is to get rid of the parasites themselves. The most effective way in this case is to contact the pest control service.

Therefore, pest control must be carried out together, otherwise the desired effect can not be achieved! In order to at least somehow protect yourself from bites to the complete destruction of insects, you should do the following: wet the room, move the bed away from the wall and other furniture, remove bedding, and wash it at the highest possible temperature.

Carefully check the mattress and pillows for the presence of the bugs themselves and their eggs (pay special attention to the seams), and it is better to iron everything with steam. Lay clean bedding so that it does not touch the floor.

If there is such an opportunity, then under each leg of the bed you can put a container of water, this will serve as a barrier. This procedure will help you protect yourself from bites at night. It is also known that bedbugs do not tolerate pungent smells and the smell of tobacco smoke.

Therefore, in order to avoid unpleasant consequences, you should carefully inspect the room in which you plan to spend the night, and if after the trip you still suspect something was amiss, then the best way would be to hand over all the things that were with you on the trip to dry cleaning.

If this is not possible, then the bag with things must be put in an empty bath, re-examine everything for bugs and eggs, shake and rub over at the highest possible temperature.

Removing and treating bug bites

In most cases, treatment for bedbug bites is not required. Any bite symptoms go away within 1-2 days. If the bite site hurts and itches, you can treat it with antibacterial soap or alcohol.

Also, folk methods for getting rid of bites include:

You can also use any soothing ointment: Afloderm, Psilo-Balm, Menovazin, etc. Tsindol is a good help - it is a healing suspension that is effective for skin damage.

If the symptoms of the bite still do not go away, you should immediately consult a doctor.

Bites of bed (home) bugs on the human body: symptoms and treatment

Bed bugs are parasites, the thought of which in some people already causes nervous scratching. These parasites do not bring any benefit to humans, with the exception of only predatory varieties of bugs that are useful for agriculture.

How to identify and recognize bug bites on a person? Let's make a small immersion in the reality of the client who first encountered bugs. Lived yourselves lived, slept peacefully and now one of the nights, you wake up.

It is not clear, whether from itching, or from bites. At best, awakening, maybe at your usual time, at worst you wake up in the middle of the night.

The situation worsens dramatically if the bites are on children or infants. A small child cannot tell what they are from, and he will only cry all night long, and his parents will only guess the true causes of redness on his body. In search of answers, you can go online, or, more often, contact your assigned doctor or therapist.

In fact, the period of time from the moment of the first bite and the subsequent visit to the doctor in order to identify their causes, takes from 1 to 3 weeks, during this the period of bedbugs, from barely visible larvae, can completely turn already full and satisfied adult bedbugs.

For this reason, it is important to recognize bite marks during this time and there is nothing better than seeing his photographs of bedbug bites at least once.

What will help to identify a bug bite? To find out that it was the bugs that left the bites, and not the mosquitoes, fleas or other parasites? How to alleviate the consequences of a bite? All this will be discussed below.

What places and who bite the most?

Bed bugs are especially preferred for people who have thin skin. These include women and children, and only in exceptional cases the male population.

Also one of the reasons why bedbugs do not like the male population is intolerance to the smell of tobacco and alcohol.

How to identify, recognize and distinguish bites of bugs from other insects?

Traces from bedbug bites differ in that there is a whole series on the wound from a bite or, to put it another way, a “path” from bites and slightly swollen depressions. Bedbug bites on a person’s body are scattered over a large area, these are small red spots that follow one after another.

Bedbugs “go” biting and leaving a lot of traces, and this feature is their unique identifier and serves as a distinctive feature of bedbugs. Given that mosquitoes are not active in the winter season, and the "bed" bug bites regardless of the time of year, we can logically come to the conclusion.

Summarizing the above, we can identify a number of key points, based on which, we can clearly say that these bite marks belong to bedbugs.

The active phase of bugs falls in the interval from one in the morning to five in the morning, which in turn imposes certain conditions that must be observed when killing bugs, namely, to keep the room closed for 24 hours so that all insects hidden during the day go out in search of food at night and most overdo it.

Thus, you can see and reveal the bites of bedbugs on the body in the morning after waking up.

Sometimes people confuse the bites of bedbugs with the bites of fleas in order to put all the dots above the “and”, you should pay attention to 2 facts:

1. do insects jump after a bite
2. Do you bite you in the daytime?

If the answer is yes, i.e. you are bitten in the daytime and it is difficult to catch insects, because they have time to jump, the only answer is fleas, not bugs.

When a bug bites, neither itching nor pain is experienced. This is due to the anesthetics contained in the salivary fluids of the parasite, so bedbugs are visible only in the morning, this is also a distinguishing feature from mosquitoes and fleas.

With an allergy, with which wounds left by bedbugs are often confused, other symptoms are often manifested, except for itching and redness: temperature, nasal congestion, tearfulness, and others.

However, it is still difficult to separate the bug bites from the allergy, so the best solution would be to consult a specialist - therapist or dermatologist, in which case you should start treatment promptly, without waiting for serious consequences.

Treatment of bites and itching from bedbugs and their symptoms

There are no special types, methods and methods of treatment and rehabilitation that can relieve the consequences of the bites of this pest. Bedbug bites themselves go away within 3 to 12 hours.

Redness subsides, irritated skin syndrome stops. However, there are people in whom a bug bite can trigger an adverse reaction of the body - an allergy, the consequences of which disappear within a longer period of two to three days.

To relieve pain and irritation from the bite of this insect, you can wipe the bitten skin with cotton wool in alcohol or rinse with soapy water. You can reduce itching from a bite by covering the site of the bite with a specially designed ointment, and also resort to taking antihistamines.

If the place of the bite began to change for the worse, the itching does not go away, and discharge (greenish, yellowish, whitish flowers) began to appear from the wound, then, without wasting time, you should immediately contact the nearest dermatology department!

How to treat bedbug bites with medicines and folk remedies

The bug bite most often does not pose a serious danger, but there is nothing good in it either. Multiple bites provoke itching and pain, an unaesthetic appearance of the skin, and restless sleep. In addition, a bug bite can cause an allergic reaction.

What you need to know

Many believe that bed bugs come from a lack of cleanliness, but this is not entirely true. Even if your house is perfectly washed, these insects can get into it on someone else’s clothes, bag or other things (after which they will safely settle and divorce in a mattress, sofa, closet or behind a carpet).

Children have a habit of combing bites, which is why bleeding wounds do not heal for a long time. Sometimes this leads to anemia caused by iron deficiency. But the main danger is an allergic reaction, which should be treated with separate drugs.

In addition, bedbugs can introduce an infection into the blood (although this happens extremely rarely), so wounds must be disinfected.

Identifying symptoms

Before treating bedbug bites on the human body, it is necessary to correctly recognize them. Faced with the situation for the first time, it is not so easy to understand exactly who bit you - a bug, fleas, or mosquitoes ...

The place of a bed bug bite looks like a small reddish swelling, not much different from the bite of the same mosquito. However, bugs have one feature - in the photo you can see that their marks “go” along the path or fold into a zigzag.

Soon, the redness begins to itch, and after a few days heal, if not combed. That would be all over, but if bedbugs started in the house, they will bite you again and again - so it is so important to quickly find their nest and get rid of it.

Treatment

If you notice bug bites on your body, the first thing you need to do at home is to wash your skin with soapy water or take a warm bath with soap.

It is also recommended to lubricate the bites on the skin with a thick soapy foam, wait for it to completely dry and only then rinse with water. This will help reduce itching and reduce the risk of infection. It is very undesirable to comb the wounds, but if you can not resist - it is better to treat the skin with special means (folk or medication).

In this case, it is better not to torment yourself, but to resort to painkillers. Multiple, poorly healing bites, allergies, symptoms of a skin infection, signs of anemia in children - all this should be the reason for consultation with a doctor.

Medications

You can quickly cure bedbug bites with the help of medications in your medicine cabinet. So, ammonia can disinfect wounds and reduce itching. If you have Rescue Ointment in reserve, treat it with your skin - it relieves pain and itching, and in addition - prevents an allergic reaction.

The same effect can be achieved with the help of Fenistil gel or a well-known ointment, popularly referred to as “Zvezdochka” (Afloderm). In the pharmacy you can buy a steroid ointment against inflammation (you do not need a prescription for it) or any other that contains cortisone (or hydrocortisone).

Against an allergic reaction, you can take a tablet of Diazolin, Suprastin, Benadril, Tavegil, Loratadin or Diphenhydramine. If you have not used these drugs before, consult a doctor and strictly follow the instructions. As a painkiller, you can take a tablet of Paracetamol, Naproxen or Ibuprofen.

Folk remedies

What else can be treated for bug bites? Often, folk remedies help no worse than medicines, especially since many of them are at our fingertips. So, a solution of soda, potato juice or parsley will help alleviate the discomfort from bites on a person.

You can reduce itching with juice from fresh mint leaves, and for lack of such, try to lubricate the skin with mint toothpaste or apply ice cubes to the bites.

The juice of this plant will reduce pain and perfectly disinfect wounds. In addition, for the treatment of bites, you can use plantain juice, essential oils, as well as onion and garlic juice (if you are not bothered by their smell).

Additional tips

When choosing a hotel or a rented apartment for an overnight stay, carefully examine the berths. It is unlikely that you can make out bed bugs, but try not to sleep on sofas or beds with unpainted wooden elements.

Polishing, metal or other smooth surfaces complicate the movement of bugs, and in an unpainted tree they feel at home.

In addition, in an unfamiliar room you should be alerted by black dots on the wallpaper and sofa, as well as a peculiar sugary smell.

Remember that an allergic reaction can appear suddenly and turn into a life-threatening anaphylactic shock. Therefore, if you suspect a bug bite, take care and take an antihistamine.

How to treat bedbug bites on a human body

Not only a neglected dormitory room or an untidy dwelling can “boast” the presence of bugs. These insects can live even in sterile clean and tidy houses, for example, having got there in a bag or on traveler’s clothes. A few individuals are enough to eventually breed a whole horde of malicious bugs.

Bit of theory

The bug is a small beetle, a representative of the family of Hemoptera.It has an oval body with a length of about 8 mm and a color from light brown to black. Life expectancy is an average of one and a half years.

The only food for bedbugs necessary to maintain their vital functions is the blood of warm-blooded creatures, most often humans, birds or pets.

This allows the bug to saturate freely, making several punctures in a row and not disturbing the victim.

Blood-sucking bugs are active mainly at night, most often they bite a person in bed during sleep, for which they are called bed bugs. However, with severe hunger, insects can detect themselves in the daytime.

Whom do bed bugs more like? The skin of children and women is more delicate and thin, so bed bloodsuckers prefer to choose them as a victim. But men may not feel the bites and not notice their consequences. Moreover, preferences for blood type in bedbugs are not scientifically confirmed.

Adults go “hunting" once every 5-10 days. For complete saturation, 3-5 bites are enough for them (about 7 μl of blood). Larvae feed faster, but bite more often, because they need food to ensure their growth.

Domestic bugs breed very quickly. Therefore, if you do not take measures to exterminate insects, you will not be able to avoid their bites. The appearance of many new wounds every day indicates a large number of unwanted residents.

What does a bug bite look like on a human body?

You can distinguish traces of bug attacks from mosquito bites by their characteristic appearance. Usually they are arranged in a chain of 3-5 pieces at a distance of 1-2 cm from each other.

The reaction depends on the characteristics of the body, it may not appear immediately or go unnoticed. Unpleasant symptoms (itching, swelling, redness) disappear after a few days or worsen with the manifestation of allergies, the development of infection.

Home treatment

In most cases, bug bites do not have serious consequences. The main nuisance is that they look more noticeable and more numerous than the attack of mosquitoes and other small insects. There are many ways to deal with these symptoms on your own, but it’s still better to get advice from a health professional.

Contrary to popular belief, a home bug cannot infect a person with an infectious disease. But the pathogen of inflammation can get into the wound after a bite, if it is not treated in a timely manner.

Folk remedies will help alleviate the condition of irritated skin, relieve swelling and itching - simple and affordable recipes:

• tea compress;
• plantain, bulb or aloe juice;
• chopped parsley leaves;
• thick soda solution.

To reduce swelling from bites, after all the recommendations described above, you can apply cold.

They can smear the skin and apply to bedding to repel insects.In addition, such aromatherapy will help relieve the stress of the victim and increase his immunity.

When is a doctor needed

With allergic reactions to bedbugs and prolonged onset of symptoms, treatment with folk remedies is already unacceptable. In this case, it is recommended that you contact an experienced dermatologist who will prescribe an external treatment and, if necessary, take the drugs inside, taking into account the existing contraindications.

As a rule, ointments (afloderm, menovazine, akiderm) and antihistamines (suprastin, clarithin) or corticosteroid hormonal drugs are prescribed to the patient. With a large area of ​​damage to the skin of the body, painkillers, for example, ibuprofen, can be used.

Continuous itching after bedbugs can provoke combing of the wound, slow its healing and cause festering from infection. To avoid this, you can use externally the well-known Vietnamese asterisk.

Treatment of a child is usually complicated by the presence of contraindications in medicines. Meanwhile, it is the kids who suffer most from bedbug bites. In infancy, it is allowed to use Bepanten ointment, which well regenerates the delicate baby skin.

When attacking a flock of blood-sucking insects, the psychological factor plays an important role, when a person sees or imagines unpleasant insects on himself, notices traces of their bites on the body or blood stains, constantly thinks of an unpleasant "neighbor" on the bed.

Therefore, he goes to sleep in tension, sleeps sensitively and anxiously, wakes up from the slightest rustle. The consequence of this is sleep disturbance, nervous tension in adults, and even fear in a child. In these cases, the use of sedatives and sedatives is justified.

How to treat bug bites on the human body

More than fifty thousand species of bugs live on the earth. In the climatic conditions of our country, there are about a thousand of them. Not all of them are parasites - this sad fame belongs to insects from just one family. It annoys a person with a bed bug.

What are the danger of bug bites for a person, how to recognize the attack of these blood-sucking insects and what means are suitable for treatment?

Bedbug is a small blood-sucking insect. They live in inaccessible places - under the wallpaper, behind the plinth, in the crevices of the floor and furniture. Insects inhabit numerous colonies. Sometimes the presence of parasites in the room can be determined by the characteristic smell, similar to the aroma of almonds or fermented raspberries.

The bug has a special piercing-sucking apparatus, with the help of which it pierces the skin on the host’s body, injects its saliva and sucks blood. Due to the analgesic substances contained in the saliva, a person does not feel the bites of bedbugs.

The nutrition process takes from three minutes to half an hour. For one feeding, the parasite sucks out about 6 μl of blood from a person. This amount is enough for the insect to provide itself with food for 7-10 days, then the bloodsucker goes hunting again.

The parasite feeds mainly at night, but with a large number of bugs in the room they can be found during the day.

Females lay eggs, from which, under favorable conditions (heat, humidity), larvae hatch. One female lays about 500 eggs in her life. Bedbug larvae should be fed daily.They are not yet able to inject saliva into the wound, so people perceive their bites quite painfully.

Than dangerous

Bed bugs can serve as carriers of such diseases. As for blood-borne infections - HIV, hepatitis - it is reliably proven: although bed bugs can be infected, they are not able to transmit the virus from one person to another.

The main danger to humans is represented by various complications caused by a reaction to insect saliva and skin damage. Attack of a large number of insects cause severe redness, itching, irritation and cause inconvenience.

Children with delicate skin are especially affected by bedbug bites. Also, the parasite prefers women and bypasses smokers and people with a blood alcohol content.

An allergy to bug bites develops quite often, however, is local in nature. With regular skin damage, allergic dermatitis can occur.

The most common complication of the parasite is various inflammatory diseases of the skin, which can be accompanied by infection of wounds and lead to pustules, eczema and an increase in general body temperature.

How long do bug bites last? It depends on the care of the wound. In the absence of infection and without combing, edema and redness disappear in 1-2 days.

Symptoms

Sometimes wounds from bedbugs can be confused with the damage that other blood-sucking insects do - mosquitoes, midges, horseflies. Since the bites of an adult parasite itself are painless, they are often mistaken for pimples and other irritations that appear on the skin, especially in children.

In order to prevent such a mistake, you need to know about the features of damage to the skin by bedbugs.

How do they look?

Spot redness, swelling, sometimes in the center you can see an injection from a bite of the skin.

Subsequently, small whitish scars form at the bite sites. When a wound is infected, mucous or purulent discharge follows from it. Perhaps a slight increase in body temperature.
