How mosquitoes find their prey and suck blood in the dark

Mosquitoes can distinguish very well certain molecules produced by the activity of human cells, such as carbon dioxide produced during respiration and lactic acid produced during strenuous exercise, and some people secrete more substances than others. As a result, those who secrete and breathe vigorously are more likely to be targeted by mosquitoes.

In addition, people who use perfumes, soaps and floral shampoos should also be very careful.

There are two other types of people targeted by mosquitoes, people who wear dark clothing in bright environments and people who are in motion. Because in addition to chemical detectors, there are about 2,700 species of mosquitoes that have quite sensitive visual receptors and thermal sensors. Mosquitoes like to bite parts of the body that are hot, such as the head.

In addition, scientists have discovered that mosquitoes are particularly sensitive insects with a keen sense of smell, and that they have carbon dioxide receptors on their small tentacles that can detect carbon dioxide gas at a distance of up to 15 meters**. Since we are breathing all the time, inhaling oxygen and exhaling carbon dioxide, mosquitoes can easily find us with this clue. And our body also secretes a volatile chemical - lactic acid, to which mosquitoes are very sensitive.

However, different people release different amounts of lactic acid, which may explain why some people are particularly "loved" by mosquitoes.

Not only that, but the warm and humid environment is very attractive to mosquitoes. When humans and other homeothermic animals emit a certain amount of heat and moisture out of their bodies, the surrounding air creates convection currents that mosquitoes are keenly aware of, albeit weakly. Following this warm and humid air current, the mosquitoes once again succeeded in "catching" us.

P.S. - anti-mosquito tips.

First, it's best to use less soap in the bath. Generally speaking, mosquitoes like to eat nectar dew, so the probability of being bitten by mosquitoes increases after using perfumes, cosmetics, creams, and other items with a floral scent. However, not all scents will provoke mosquitoes, such as the cologne commonly used by men because of the sandalwood scent, which can play a role in repelling mosquitoes.

Second, eat more vegetables. Some vegetables contain odors that mosquitoes don't like, such as carotene-containing vegetables and spicy vegetables such as garlic, which will keep mosquitoes away from you after people eat them.

Third, wear light-colored clothing. Aedes mosquitoes, also known as Aedes versiflora, prefer to rest on black clothing.

Fourth, try to wear socks as much as possible. Many girls like to wear shoes barefoot, but after wearing socks, mosquitoes feel that people's **humidity decreases, and volatiles on the skin surface decrease, which will reduce bites.

Fifth, you can't scratch after being bitten. After scratching, the tissue fluid, lymph and other fluids in the ** ooze out and swell into a bag, which will become more and more itchy, and it is not easy to subside, and the "red bean legs" covered with red envelopes are scratched out in this way. If you insist on not scratching, the itching will subside significantly after 10 to 15 minutes.

Faint fluorescence emitted by the human body.

1. Mosquitoes are afraid of light but don't like the light too dark, and like to suck blood in a low-light environment.

2. Mosquitoes fly to dark places, and mosquitoes are rarely encountered during the day. Mosquitoes only start to get on when it's almost dark, and mosquitoes are rampant at night. Therefore, it likes to be dark, and the reason why it flies to the bright place at night is because there are people in the bright place, and people will produce carbon dioxide when they breathe, and mosquitoes are flying at carbon dioxide.

3. For mosquitoes, the carbon dioxide and sweat emitted by the human body are effective information to guide Sakura Chong to find its prey. It mainly relies on its olfactory organs, that is, a pair of horns on its head, to perceive the "information" of the human body in the air and follow the traces.

4. Mosquitoes also like to fly to places with temperature, so the body surface of the human body or animals is the place where mosquitoes are willing to go.

5. Mosquitoes need to lay eggs in a place where there is water, so don't use the water at home and pour it out in time.

Mosquitoes like to suck blood in dark places because it is safer, can ensure that they are not shot to death, and it is easier to hide.

Mosquitoes mainly use infrared and carbon dioxide to find their hosts, so they can hide themselves better in low-light environments, which makes them relatively safe in the dark.

The main purpose of mosquitoes to suck blood is to obtain nutrients, they are very adaptable to the environment, and the companion can adapt to a variety of different environmental conditions. Therefore, whether it is in the bright sunlight or in a dimly lit corner, as long as you can find an environment and food suitable for your survival, mosquitoes will suck blood in it.

In general, mosquitoes prefer to be active in dark places, but they don't necessarily only suck blood in dark places.

Mosquitoes do rely on their eyes to find targets, but mosquito eyes are different from humans, mosquito eyes occupy 3 4 of the head has a very large viewing angle, and mosquitoes can also see infrared, so mosquitoes can judge the location of their prey at night through the infrared rays emitted by the targetLet's learn more about the blood-sucking process of mosquitoes.

1. Look for a target

Mosquitoes are actually looking for targets very quickly, first through the smell of mammals, and then can be used to roughly find the direction of the target, mosquitoes will quickly approach the target, and when the distance is closer, mosquitoes can accurately locate the location of the mouth through their eyes. Mosquitoes use infrared radiation from the human body to distinguish the location of blood vessels, so mosquitoes can also quickly suck blood at night because darkness does not affect them much.

2. The process of blood sucking

Mosquitoes also suck blood very quickly, it only takes about 3 seconds to complete, but in the time it takes to open up, mosquitoes go through a lot of steps. Mosquitoes first have to inject anesthetics in the ** to prevent them from being found in the process of blood sucking, and then change the early Ling will inject formic acid in the **, this substance can destroy the ** and the blood vessel wall mechanism, so that the mosquito punctures the ** and the blood vessel wall more easily, the mosquito straw will be injected after the blood vessel will be injected with anticoagulant to prevent blood clotting, and then start to suck blood.

3. Anti-mosquito methods

Mosquitoes bite at night and are harder to detect, so be sure to protect yourself in advance. The best way is to use screen windows, screen doors, mosquito nets and other tools to isolate, you can open up a mosquito-free area, you can use an electric mosquito swatter to eliminate mosquitoes indoors, can effectively improve the mosquito prevention effect. The use of mosquito coils, insect repellents, and insecticides is not recommended here, because these things may have adverse effects on human health, and secondly, mosquitoes reproduce quickly and evolve quickly, and after a period of time, a large number of resistant mosquitoes will be born, which will lead to the effectiveness of these things getting worse and worse.

Introduction: Many people have experienced mosquito bites and feel very irritable.

There are many people who are very strange and don't know why mosquitoes still bite them when the lights are turned off at night, and they are always very irritable.

There are many people who like to use soap when bathing, which also provides a way for mosquitoes, mosquitoes like the smell of incense, and mosquitoes will bite when they smell the smell.

Many people will be itchy after being bitten by mosquitoes, so don't scratch them with your hands all the time, but properly alleviate your symptoms and hang mosquito nets in the room. Some people are very curious, find that they are on the light, mosquitoes are always flying around, turn off the lights mosquitoes will still bite themselves, I don't know why this happens, mosquitoes are generally through fragrance when looking for prey, usually do not use items with flower fragrance at night, this will also make mosquitoes smell mosquitoes in the process of biting will also be very uncomfortable, bath must use a little better skin care products, do not have a floral smell. If there are always mosquitoes in the room, you should also solve it, don't let yourself suffer from mosquitoes, make yourself more comfortable, and usually pay attention to protect your body, so that your body can be healthier.

Some people who are bitten by mosquitoes will always get a big bag, and at this time they must be carried out in time. Be sure to relieve the itching on your body, and be sure to treat it if you are accidentally bitten by a mosquito.

Mosquitoes are very sensitive to their senses, and mosquitoes use heat sensing to find their prey, so when an object is heated in the dark, the mosquito will find its target.

Mosquitoes look for them by smell because they have very sensitive senses. That's why you can catch your prey accurately.

Mosquitoes find prey based on the temperature and smell of humans, so they can find prey even in the dark.

Mosquitoes generally seek out their prey by smell and heat. And mosquitoes have a certain sense of ability.

The human body has the smell of secreted bodily fluids, and the human body also has temperature, which they can perceive.

Mosquitoes have antennae and bristles on their heads and legs, and they are sensitive to humidity, temperature, and sweat, so they often bite people who sweat and do not bathe. Children's **delicate, metabolism is lively, **pores volatilize sweat quickly, and they are often bitten by mosquitoes. Also, mosquitoes are very fond of low light, and if you wear a black outfit, it is just right for the mosquito's visual habits.

However, mosquitoes are sensitive to strong air currents, and it is difficult for mosquitoes to approach you in the summer when you shake your fan to cool off.

Smell, for example: people with smelly feet are the most likely to attract mosquitoes

Mosquito bites are really annoying on summer nights. In a dark room, mosquitoes are able to find people or animals with unerring accuracy and fly to suck their blood, mainly thanks to their developed sense of smell. Mosquitoes can accurately locate people and animals by the smell of carbon dioxide produced when they breathe.

Mosquitoes can accurately find people and animals by the smell of carbon dioxide produced by human or animal breathing, and it can also sense human and animal body fluids and smell the smell of people and animals**.

Because people have a special taste.

Mosquitoes can find people by their smell and breath.

Because the human body emits some odors.

It is possible to find people by their scent.

He can find people by their scent.

He could feel the blood of people and. Smell.

They do not rely on the eyes, by virtue of the special smell of human blood.

Because people release carbon dioxide.

Feel the bodily fluids of people and animals, and smell the smell of people and animals**.

The mosquito has a sensitive sense of smell, and it must first smell human odor, including human body odor, the smell of exhaled carbon dioxide and other gases, it can smell it. In addition, it can feel the heat released by human temperature, and people with strong physiological metabolism are more likely to be found by mosquitoes. When a mosquito approaches a person, it can see it up close, even though it has poor eyesight, and it will quickly pounce on the human body and suck blood.
