    Scientific research has found that mosquitoes are more likely to bite people because of many factors, such as the smell they emit, chemicals on their skin, and the amount of carbon dioxide they emit when breathing Experts estimate that about 10% of the population is favored by mosquitoes, and 85% of the more mosquito - attracted people are genetically predisposed Another study shows that people who are less attracted to mosquitoes can emit mosquito repellent smells and chemicals Of course, this is only preliminary research results In fact, there are many unknown reasons why mosquitoes prefer to bite some people Why do mosquitoes bite? It should be known that only female mosquitoes can bite humans They do this for the proteins and nutrients in the blood, which are needed to lay eggs Before they lay their eggs, they look for a blood meal Usually, they feed on nectar and other plant juices Female mosquitoes locate their prey by detecting carbon dioxide, the gas that animals emit through their breath and skin Mosquitoes use a structure called the maxillary tentacles to detect carbon dioxide 50 meters away, but at closer range, they use feathered antennae to identify certain chemicals; there are many small holes in their noses through which the smell of the air can penetrate After the mosquito discovers the high concentration of carbon dioxide released by the human, the mosquito's sensor will judge whether the chemicals and smells released by the human constitute suitable prey In addition to carbon dioxide, some substances produced by the human body that attract mosquitoes include sweat, lactic acid, uric acid and a chemical called octenol The skin releases lactic acid (especially during exercise); uric acid is the product of metabolism of some proteins in the human body, and most of it is excreted through urine, but the excess uric acid will also accumulate under the skin; octenol exists in human sweat and breath Some people produce more of these substances, so they are more likely to get mosquito bites Large people and pregnant women usually exhale more carbon dioxide, so the risk of mosquito bites is higher People who exercise outdoors produce more lactic acid and sweat, and breathe more, so they are bitten more by mosquitoes In addition, perfume and deodorants used to cover the body's natural odour will also attract mosquitoes Mosquito repellent substances commercial repellents contain a variety of chemicals, such as the well-known DEET, which can repel mosquitoes by hiding the chemicals in the user's body or inhibiting the insect's sensory organs However, some studies have found that some people have certain substances in their skin that can reduce their attractiveness to mosquitoes Two of them are geranyl acetone and 6-methyl-5-hepten-2-one.
