Mosquitoes bite people is not divided into blood type, "blood type" is not reliable.

The common saying is: mosquitoes prefer O and B blood type people, do not like to bite AB blood type people, in fact, mosquitoes will not distinguish between people's blood type.

Human sweat also contains a variety of volatile chemicals can attract the attention of mosquitoes, sweat glands developed, rough skin, large pores of the people, discharged sweat and other secretions more, the blood acidic enhancement of the sweat discharged to make the surface of the body lactic acid value is higher, more likely to mosquitoes have attraction. Therefore, sometimes men are more attractive to mosquitoes than women and youth than the elderly.

The combination of amino acids and lactic acid in human blood will generate a composite amino acid mixture, this material and sweat slightly sweet amine combination, can generate trimethylamine, and trimethylamine odor has a strong mosquito role, the child is generally more active, metabolism is strong, the body's trimethylamine content is higher, the possibility of mosquito bites is also higher.

Many kinds of hair gel, hand cream, face wash and other cosmetics because they contain special odor chemicals, the temptation of mosquitoes are extraordinary, so the use of stearic acid-containing perfume, hair gel, creams and other floral-scented cosmetics, as well as butter creams, the chances of mosquito bites will be greatly increased.
