Mosquitoes are obviously in the dark, why do they know that there are people?

Introduction: In the summer, there are always some annoying insects, flies during the day, mosquitoes at night, and mosquitoes will also suck people's blood, so that many people hate mosquitoes very much, and sometimes spread diseases. But what makes people feel very strange is why mosquitoes know that there are people when they are in the dark?

In fact, many animals that move in the dark do not rely on their eyes to observe their prey, because the light is too weak to function by their eyes. Therefore, the location of the prey can only be located through other information, and mosquitoes appear in the summer, and the best way for mosquitoes is to locate the position of the person through the smell of human sweat and the carbon dioxide exhaled by the human body. That is to say, for mosquitoes, they don't need to know what people look like, they just need to know what people look like.

For example, in summer, people will always unconsciously sweat, these sweats will have some volatile gases, and the carbon dioxide emitted when breathing will also be felt by mosquitoes. And in the summer, the temperature of the human body is different from the temperature around it, so mosquitoes can locate the location of the person and take their own actions.

In fact, in the summer, we must pay attention to mosquito control, there are many people who live in high-rise homes, so it is relatively cleaner, but there will also be mosquitoes. Mosquitoes carry many pathogens and may send these pathogens into the bloodstream during contact with people. Therefore, it is necessary to clean in time in daily life, especially in the bathroom, these damp parts are easy to accumulate mosquitoes.

In addition, in daily life, it is necessary to build mosquito nets appropriately, which is very helpful for mosquito control, so that you can make your summer more comfortable. After being bitten by a mosquito, it is necessary to wipe it with a medicated solution so that it can be disinfected in time.

Mosquitoes are often found in dark environments, and mosquitoes identify people by their sense of smell. Mosquitoes have a very sensitive sense of smell, which is the mosquito's sensory organ.

This is because mosquitoes can sense people based on their temperature and smell, so mosquitoes generally bite people at night.

You can judge by smell, there are sweat stains on the body, there is smell, you can judge by smell.

Because the human body excretes carbon dioxide and sweat, mosquitoes follow this information to find humans.

Dark. You're not hot!

Mosquitoes usually prefer relatively dark places, they are usually active during the day and look for a safe place to rest at night. Specifically, they often hide in dark corners of the room, such as behind the wardrobe, under the table, in the corner of the window sill, etc., basically hiding themselves during the day and coming out at night.

However, there is a part of mosquitoes that prefer bright places, and they usually spend time outdoors, looking for water and places for human activity. They especially like to stay on the water, flower beds, and parks, as these are usually brighter, with plenty of sunlight and heat, and may also have foods that attract them, such as nectar or sugar water.

To sum up, mosquitoes tend to be in dark places when choosing a habitat, but some mosquitoes prefer bright places.

Mosquitoes love the dark.

Mosquitoes are nocturnal animals that prefer to fly in the dark, and mosquitoes prefer to hide in warm, moist, unventilated shelters. There are more mosquitoes in places like basements, barns, bridges, and wall cracks. But mosquitoes are easily attracted to light, heat, and carbon dioxide exhaled by humans.

Therefore, when we sweat after exercising, it is especially easy to attract mosquitoes.

Mosquitoes are afraid of light, and they prefer to fly in low-light environments, so they are generally more likely to attract mosquitoes to roll and bite in the evening. In low-light environments, mosquitoes can rely on their sense of smell and the heat and carbon dioxide released by the human body to distinguish people's orientation.

Ways to repel mosquitoes in your home:

1. Plant mosquito repellent plants.

We can plant a little mosquito repellent plant like wormwood, pyrethrum and other mosquito repellent plants at home, so that we can reduce the number of mosquitoes in our home.

2. Clean up the stagnant water at home in time.

Mosquitoes breed and lay eggs in stagnant water, so we should clean the stagnant water in the floor drain, pool and other places in the home in time to prevent mosquitoes from breeding everywhere.

3. Cool oil to repel mosquitoes.

Put a few bottles of cool oil or wind oil essence in the vent of your home and open the lid to keep mosquitoes away from the room and fresher the indoor air. <>

Because mosquitoes rely on their very high eyesight to find people. The basis is that mosquitoes have a very important sense, that is, the identification of heat, and mosquitoes also rely on the heat emitted by people to find people, so that they can find the location of more blood.

This is because mosquitoes do not see people with their eyes, they rely on the heat emitted by the human body to know that there are people.

Because mosquitoes are nocturnal animals, their eyes are very bright at night, and their bodies are also very sensitive, so they can tell if there are people.

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.
