After puncturing the skin with their mouthparts and feeding on blood, mosquitoes leave hard, itchy bumps. In the blood-feeding process, mosquitoes inject saliva into their host which creates the reactions that cause bite symptoms. Most mosquito bites are harmless and the symptoms subside in a few days. Some discomforting symptoms include swelling of the bite site, soreness, and bleeding. While mosquitoes are an itchy, uncomfortable nuisance, the important problem arising from mosquito bites is transmission of viral or parasitic diseases.
Q. Why does your skin puff up after a mosquito bite or bee sting? A. Swelling is the normal reaction to an insect bite or sting. Chemicals in the venom result in the dilation of blood vessels, causing fluids to seep into the surrounding tissue.
