Why mosquitoes can find the exact location of people even when it is dark at night

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. - Mosquito prevention tips First, it is 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.

Because it has a heat-sensing organ, and the human body has body temperature, plus the smell of sweat and other body odors of the human body, of course, it can find the exact location of the person! Choose me, thank you!

The mosquito's nose still works, you have a smell on your body, and he found out about Sai.

Mosquitoes target by smell and are particularly sensitive to the smell of sweat.

Because mosquitoes don't look for prey by sight. It seems that they rely on their sense of smell.

The room is not clean, the people are not clean, the smell of human sweat and other body odors will find you.

It has heat-sensing organs, and people have body temperature.

You can find something to eat even when you're hungry, can't you?!

It can smell on people.

When mosquitoes are looking for the location of people, they will find it reasonably through the heat source, and secondly, they will also find it reasonably through the taste, so it is very accurate.

It is because mosquitoes can exhale carbon dioxide when people are sleeping to find the position of people, which is also a special function of mosquitoes.

It is the antennae and senses of mosquitoes that make the smell of human blood, and mosquitoes will come to it according to the taste.

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.

Whether in a dark room or outdoors with no fingers out of sight, vampire mosquitoes are able to find the location of a person or animal with unerring accuracy and fly to suck their blood for three main reasons:

Mosquitoes can accurately locate people or animals by using the smell of carbon dioxide (carbonic acid) in the breath they exhale.

Feeling the body temperature of a person or animal.

Smell on people or animals**.
