Why do mosquitoes bite? Female mosquitoes are having piercing mouthparts. Female mosquitoes extract the blood from the host with these mouthparts. The protein that is gathered from the blood is used in egg production. Male mosquitoes do not bite. They are not feeding themselves from the blood. Their energy comes from nectars and other sweet substances found in their habitat. Female mosquitoes are puncturing the skin of the host with their mouthparts. After this action, they leave the host skin with hard and itchy bumps. When they are feeding with the blood of the host, they put saliva into their host. Saliva creates the reactions that are causing bite symptoms. Most of the mosquito bite are harmless. Also the symptoms are subsiding in few days. Some of the discomforting symptoms can include soreness, bleeding and swelling of the bite side. Mosquitoes are itchy and uncomfortable nuisance. The most important problem arising from the mosquitoes bites in transmission of viral or parasitic disease. With the most known insects when they are biting we know that there is a risk of secondary infection. This is the case also with mosquitoes bite.
