Bed bugs are parasitic insects, from the presence of which even the cleanest housewife cannot be insured against in the house. Pests can start in a bed where a person sleeps, since it is he who is the source of food for parasites. Most people think that bloodsuckers carefully select their victims. So staying in one apartment, one person can suffer greatly from the bites of bloodsuckers, the other will not even notice their presence. Why bugs do not bite all people, and how can explain their food selectivity, let's try to figure it out in this article.
Who do bloodsuckers prefer?
Many are interested in why the bugs bite some, but others do not. These insects feed only on blood. To prey it, they attack sleeping people. Why do not bugs bite everyone? This is due to the fact that pests have their own preferences. Most often, they attack people who do not recognize pajama suits. Sleepers without blankets also become victims. In these cases, insects do not need to look for open areas of the body. Sleepers are attacked so that blood can be drunk.
The explanation why bedbugs do not bite everyone is still associated with age. Children are often the victims. Moreover, the younger the age, the greater the risk. Children's skin is thin and delicate, making it easier for insects to find food. Why bugs do not bite everyone depends on the gender. Often insects attack women. Their skin is significantly thinner than that of men. Pests feel the smell of blood well. Male bugs bite less often. And the blood type does not affect this.
What blood type do they like
Interested in whether harmful bugs drink human blood, one should immediately stipulate their subspecies. Garden parasites live off plant products or insect debris. Household pests - bloodsuckers, cannot exist without the blood of people.
Bedbugs are night guests. Therefore, they eat in the evening when the victim is asleep. The time interval is between 3 and 8 am. Due to the presence of special enzymes in their secretion, the bite is painless.
During the day, the bug drinks blood only if it is impossible to do this at night. For example, the owner leaves for work in the evening and goes to bed in the morning.
Many people are interested in knowing which blood type bed bugs love more. There is an opinion that some parasites do not spare at all, while others may not be touched at all.
Bloodsuckers are not physiologically capable of determining other blood parameters. That is, insects bite equally representatives of all groups, regardless of the Rh factor.
People have different sensitivity of the body to the bites of bloodsuckers and not everyone can understand in the morning that they were attacked by a clan of bedbugs. By consuming blood, bugs drink it more often in women and children.
This is due to the thinness of the skin and the minimum amount of body hair. At the same time, the parasites are attracted by the exhaled smell of carbon dioxide, which is greater in a massive man. Therefore, everyone is susceptible to bites, without restrictions on age, sex or blood type.
To understand how often bed bugs eat, it is worth considering their age. An adult female eats 1-2 times a week and drinks up to 10 ml of blood at a time.
In hot climates, meals are required more often. The rate of their reproduction depends on how often the bugs drink human blood. On average, the female lays up to 250 eggs during her life.
The male can get enough of 5-7 ml of blood, which is several times higher than the insect's own volume. The duration of the meal is 10-20 minutes, during this period the parasite makes 2-4 bites.
Larvae and nymphs eat little, but often. This is necessary for a quick transition to a new level of development. Without food, all processes stop. In suspended animation, eggs can spend up to 1 year. Vital functions resume when a victim appears nearby.
The owners of the third and fourth groups are least likely to be attacked by bloodsuckers. When the first and fourth people were sent for a walk, there were practically no bite marks on the second. At the same time, there were a lot of other bites.
Scientists cannot provide more accurate and confirmed information.
Mosquitoes are famous for their selectivity, looking for the "very" taste of blood. Scientists explain this selective approach by blood group. Some groups are more attracted to them than others, such as the first, especially if it is Rh negative.
A team of scientists from Japan conducted a small experiment, they tested the reaction of several groups of mosquitoes to people with different blood groups. Most of the mosquitoes circled around the people with the first group. Even those individuals who had their proboscis removed sat on representatives of the first blood group.

The danger
Considering the topic of why bedbugs do not bite all people, you should familiarize yourself with the signs of damage. This is not difficult to determine. There will be a path of red spots on the skin. The affected area is itchy. But combing it is not worth it, so as not to introduce an infection, which leads to more pain and inflammation.
To eliminate the effects of bites, water and soap are used. After washing the skin, the painful area is treated with natural oil or a soothing ointment. Alcohol-based formulations are suitable. Antihistamines can reduce inflammation:
- "Diazolin". "Diphenhydramine". "Suprastin".
But before taking these funds, it is advisable to consult a doctor. When choosing a room for the night, you should inspect the space and bed. This should be done especially in inexpensive hotels.
After sleeping, some people notice chains of swelling on themselves. This is damage from bed bugs. They lead to pain and itching. If you don't touch them, they will disappear. The reason why bedbugs do not bite some people is due to time. These bloodsuckers are active at 3-5 am. At other times they hide.
Harm
The article lists all the reasons why bed bugs do not bite all people. These blood-sucking parasites are considered carriers of various diseases. But there is no evidence of this fact. This is due to the fact that the proboscis of insects is divided into 2 jaws, the blood cannot be contaminated, since it passes only through 1 tubule. But you shouldn't take risks.
Due to night attacks, people cannot get enough sleep and rest, since the wounds itch and hurt. Therefore, bedbugs are one of the unpleasant insects. It should be destroyed as soon as possible. If you delay with this process, then the house will turn into a bug, and it will be very difficult to sleep at night.
A little about gender
We all know that only female mosquitoes feed on blood; plant food and moisture are enough for males. Females, on the other hand, carry offspring, and the larvae need a full set of nutrients. Where to look for it, if not in the blood of large mammals, such as humans? Our blood is practically a ready-made nutritional cocktail for tiny mosquito larvae.

However, among the victims of flying bloodsuckers, there was also a share of sexism.Some studies have shown that mosquitoes prefer to bite children and young women because their skin is thinner and easier to bite.
Reasons for the smell
Why are some people not bitten by bed bugs? This may be due to the presence of rough skin. Through it, insects cannot feel the blood. Therefore, bugs rarely bite men. These pests also bring a characteristic smell into the room: cloying and tart, like almonds or rotten raspberries.
The odor can increase in areas where parasites are concentrated. These are usually sleeping places, old linen storage, book shelves, paintings and boxes. Pests are able to lay their eggs in electronic devices.
These insects have glands, so they give off a smell. The gland secrete a component whose purpose is not fully understood. It is assumed that this smell is required for the reproduction of parasites, protection from enemies.
The main goal of research
Scientists and pharmacists are conducting research to identify and isolate specific elements that attract or repel mosquitoes and mosquitoes to create a versatile bacteriological spray that will protect the skin from mosquito bites.
Well, who among the constant victims of these itchy bloodsuckers would not want to cover themselves from head to toe with harmless bacteria to get rid of the eternal persecution? However, research is progressing painfully slowly, and mosquitoes are famous for their high adaptability, so there is no need to rejoice in advance. So far, no one has canceled traditional methods of protecting against insects!
When do bites disappear?
Why some are not bitten by bugs? The reason may be that the person sleeps in pajamas and under the covers. In other cases, people become victims of these pests. Therefore, you should familiarize yourself with them in more detail.
Bed bugs are 3-8 mm in size, depending on blood saturation. By the color of the pest, you can determine when it last ate. If it is scarlet, then the blood was received recently. Black indicates hunger and the need for night hunting.
The food method is human and warm-blooded animal bites. To do this, the pest uses the proboscis, which pierces the body and sucks blood. The bug feels the circulation of blood and the warmth of a person. There are a pair of channels inside the proboscis.
The first is used to inject saliva, which relieves pain. The second channel is used for blood absorption. The pest pierces the body and finds a blood vessel with its proboscis. Because of the anesthesia, the bite is not felt, so it is difficult to catch the parasite.
Carbon dioxide
Mosquitoes and mosquitoes, like sharks in the air, flock to the smell of blood, which they can smell several kilometers from the victim. However, this is not their main sensory activator. Mosquitoes find victims by the carbon dioxide we breathe out. The more carbon dioxide a person produces, the more he attracts insects to him.
Certain types of people produce more CO2 than others. These types include, for example, large people, pregnant women, beer drinkers and people who sweat a lot.
Effects
The duration of the bite healing depends on the characteristics of the organism. Another important factor is the strength of immunity, the tendency to allergies, as well as the characteristics of the skin. Some people have a severe allergic reaction that disappears within 5-7 days. And a person with not very sensitive skin feels discomfort only for a day.
If long chains do not go away for weeks, you need to see a dermatologist or use folk remedies. It is preferable to use antihistamines. An unpleasant consequence is the infection of the scratches.
There is an assumption that bed bugs carry tuberculosis, smallpox, hepatitis B and other dangerous ailments. But this has not been confirmed for sure.It has been proven that in waste products there are rickettsiae - microscopic intracellular pests from bacteria.
Animal bites
Bed bugs feed 98% of human blood. Can they bite pets? They rarely do this, which is due to several reasons.
Many animals have a thick coat, which makes their way to the skin difficult, and sometimes even impossible. Even if the bug gets on the wool, it will be quite difficult to get to the power source. The skin of animals is thick and dense with many sebaceous glands, which is difficult to bite through.
Many pets are nocturnal. They have developed senses, 10 times better than humans. Therefore, they notice and destroy bedbugs.
Animals have a strong individual odor that is different from that of a human. Bedbugs are capable of smelling. Probably, this smell does not cause appetite in the bug, provided that human blood is supplied in sufficient quantities.
There is also another danger. Stray cats or dogs that a person has brought home can bring these insects. Therefore, pets should be washed with an antiparasitic shampoo, and the ears should be carefully treated.
How many fleas live
An adult flea can easily survive for several weeks without food. But, females do not lay eggs without blood, so sooner or later they will look for a source of food. People have a pretty good stomach feast for them, regardless of their preferred food (cat and dog blood).
Flea bites can most often be found on the leg, around the ankles, shins, as they easily jump off the floor.
They will also migrate to places where there is a good blood supply near the surface of the skin, such as the bend of the elbow or knee, where the garment is closest to the skin, such as the waist.
They also like to be around hair growth areas such as the head, armpits, or groin.
What to do?
To protect yourself from bed bugs, you should take precautions. Parasites hide under the mattress, in the upholstery of the sofa, in the pillows. To protect against parasites, the following measures are applied:
- It is required to block the ways of their penetration. They enter apartment buildings through sockets, ventilation, cracks, cracks in walls, ceilings, floors, as well as windows and doors. They must be sealed with cement, nets, rubber seals. Household appliances and furniture should be inspected. It will be possible to completely eliminate pests when a breeding ground is identified. Fresh bunches of wormwood should be laid out in the corners of the apartment. Parasites cannot tolerate this smell, as it obscures a person's scent and makes it difficult to find a victim. Inflorescences of tansy, wild rosemary, chamomile and calamus have the same effect. When washing bedding, add a few drops of tea tree oil. Before going to bed, it is advisable to use a shower gel that has a lavender scent. You can simply rub the essential oil into your skin. The parasites don't bite then. Also, this method has a positive effect on a person: the agent soothes, relieves irritability and headache.
Chemicals can also be used when the family grows. Plants and oils are used only as repellents - to repel adult insects, but they do not work on eggs.
How to completely eliminate bedbugs?
It is difficult to completely eliminate insects. Alternative methods are suitable, with minor infestation with bedbugs. But in other cases it helps only for a while, and then the pests appear again.
If the infection is strong, it is advisable to contact the SES or a commercial disinsection company. Only in this case it will be possible to carry out successful work to eliminate pests.
