Nearly everyone is sensitive to mosquito bites, but every year, during the warmer months, mosquitoes appear and so do the red, itchy welts, that usually appear after they bite. Why do they do this?
All adult mosquitoes feed on the nectar of plants to get sugar. The sugar provides both male and female mosquitoes with the nourishment they need to live. The female mosquitoes, however, produce eggs, and in order to do that they need protein. Where might a female mosquito find protein? They get it from the blood of humans, mammals, birds, reptiles and frogs.
Female mosquitoes track their food source using a combination of odor, exhaled carbon dioxide, and chemicals in the person’s sweat. When she finds her meal, she lands on an area of exposed skin and inserts her proboscis in search of blood (the proboscis is the long, flexible tube extruding from her head, and it’s capable of piercing human skin).
