there are several factors that cause mosquitoes to bite someone.

Blood group
According to research, people with blood type O are more likely to often get mosquito bites than people with blood type A, while the middle position is occupied blood group B. Blood type is detected because unconsciously, humans are able to remove signals from blood group compounds through the skin. Mosquitoes also prefer to attack humans rather than animals.

Carbon dioxide emissions
According to research, the older and larger the size of a person's body, the carbon dioxide emissions released by the breath will also be greater. Mosquitoes can easily search for prey by identifying carbon dioxide from the breath from a distance of 164 feet or about 50 meters. Therefore, adults are more often bitten by mosquitoes than children or infants.

Metabolism and body heat
In addition to emitting carbon dioxide, humans also produce other compounds used by mosquitoes as indicators. When it has solid activity and sweating will appear lactid acid, uric acid, ammonia and other compounds. From the smell of these compounds the mosquitoes can identify where their "food" lies.

Bacteria on the skin
Human skin has various types of bacteria that live on its surface and there is a special colony of bacteria that attract mosquitoes, mosquitoes will perch on human skin. After detecting the presence of "food" in the form of blood under his feet, then quickly this small creature will plug the "needle" into the human skin

Pregnant women
Pregnant women are preferred by mosquitoes compared to ordinary women or men because pregnant women produce 21 percent of carbon dioxide emissions and body temperature of about 1.26 degrees Fahreinheit (-17.2 degrees Celsius) higher than other humans.

Color of clothes
According to James Day, a medical entomologist from the University of Florida stated that mosquitoes more easily detect and interested in victims who wear clothing with black, dark blue and red than other colors.

Alcoholic beverages
If a person drinks an alcoholic drink, it will increase the level of ethanol in sweat and body temperature will also rise.
Someone with a high body temperature, hot body temperature, will be preferred by mosquitoes.
