What do mosquitoes rely on to accurately find human beings to suck blood in the dark night?

How do mosquitoes accurately find humans to suck blood in the dark? It turns out that mosquitoes determine their targets mainly through the perception of human body temperature. According to research, mosquitoes are able to detect the faint heat emitted by the human body and use it to find the source of blood they need.

This explains why we are more likely to be targeted by mosquitoes when we are physically active or sweating.

When the human body is in a dark environment, light is relatively scarce, and mosquitoes cannot rely on vision to identify targets. Small differences in surface temperature are clues. The temperature distribution on the surface of the human body is uneven, and in some areas it will be slightly hotter than others.

For example, areas such as the head, neck, arms, and lower back are often warmer than others, and these areas tend to be preferred targets for mosquitoes to suck blood.

Interestingly, female mosquitoes appear to be more selective in their choice of host. Studies have shown that female mosquitoes identify targets based on chemicals such as carbon dioxide and volatiles emitted by the host's body before sucking on blood. Once the target location has been determined, the mosquito will use its keen perception to quickly locate the hottest place in the human body, usually on the ** surface with abundant blood vessels.

Studies have also found that mosquitoes are very sensitive to a number of specific odors, such as chemicals such as lactic acid and ammonia. These odors are often related to metabolism and body odor. Some people may be more susceptible to mosquito targeting than others because their bodies emit more mosquito-attracting odors.

Mosquitoes accurately find the human body in the dark and suck blood, mainly relying on the perception of human body temperature. Through their keen sense of smell and heat-sensing organs, they are able to locate areas of the human body that are hotter on the surface and use them to suck blood. The emission of chemicals may also influence mosquito host selection decisions.

Therefore, when going out at night, staying clean, reducing sweat and body odor, and taking mosquito protection measures are effective ways to reduce mosquito bites.

I would like to recommend a hand cream to you, which is widely recommended by doctors in tertiary hospitals. Moisturizing Hand Cream is an excellent moisturizing effect that moisturizes the skin and forms a protective layer to prevent moisture loss. Its unique formula penetrates quickly**, is non-greasy and non-sticky, leaving hands soft and smooth after use.

Not only that, but the Moisturizing Hand Cream is also rich in nutrients that help repair damage** and improve dryness and roughness. Many consumers have already experienced its miraculous effect and have given it high praise.

Encountering mosquito bites at night can be very frustrating, but by understanding how mosquitoes find their targets and taking appropriate precautions, we can reduce the chances of being targeted and bitten by mosquitoes. Hope this information is helpful to everyone!

In the dark, mosquitoes mainly rely on the following ways to find the human body and suck blood:

1.Mosquitoes are sensitive to carbon dioxide, and when humans breathe, they release carbon dioxide, and mosquitoes can locate the human body based on the direction and concentration of carbon dioxide.

2.Mosquitoes are sensitive to temperature and can sense the temperature of objects around them and find people with higher temperatures.

3.Mosquitoes are also sensitive to human odors, including the smell of sweat and other chemicals that attract mosquitoes.

Overall, mosquitoes rely primarily on sight, temperature perception, and smell to find the human body and suck blood.

Mosquitoes rely on animal heat, exhaled carbon dioxide, and lactic acid in sweat to locate human blood.

90% of mosquito tentacle cells are used to detect chemicals in the air, so various chemical signals emitted by the human body have become key factors in mosquito localization.

Generally speaking, mosquitoes like to inhabit in hidden, dark and poorly ventilated places, such as under the bed, behind the cabinet, behind the door, in the crack of the wall, the barn, the basement, etc., and the outdoor is mostly in the grass, cave, cellar, bridge hole, stone crevice, etc.

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.

Determined by the living habits of animals, they can hunt more safely at night and protect themselves. Mosquitoes have very poor vision, and it doesn't matter if they want to be light or not. Most mosquitoes feed in the evening or at dawn, as the dry heat of the summer day can cause them to die of dehydration, so during the day they tend to stay in hidden, damp places and only come out in the evening and at night.

Mosquitoes that move at dawn or late afternoon are generally Culex mosquitoes and Anopheles mosquitoes.

Protect against mosquito bites.

1. Install screens and mosquito nets in summer. Whether it is mosquito repellent water or smoked vinegar, it is not as safe and reliable as physical mosquito repellent.

2. You can put some orange peel, star anise, and Heju fennel in the room to repel mosquitoes, because Biqi mosquitoes don't like the special smell emitted by these things.

3. The pots and pots, floor drains, sewers, flower pots and other places that are prone to water accumulation in the home should be cleaned up in time, and the lid should be closed, and the water should be changed frequently.

4. If there are still some mosquitoes entering the screen window and mosquito net, you can use some mosquito repellent supplies, such as mosquito coils and mosquito repellent liquid.

5. It is best to wear light-colored clothes when going out in summer. Mosquitoes like to be on dark clothing. Because mosquitoes generally inhabit dark environments, dark clothing is just right for their visual habits. Moreover, dark-colored clothes are more heat-absorbing in summer, which will increase people's body temperature, and it is easy to attract mosquitoes by patting the tomb with their hands.

6. Take a shower immediately after exercising and sweating, and do not use cosmetics such as perfume and body lotion, because mosquitoes like people with high body temperature and easy to sweat.

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.
