Answer:
Nearly everyone is sensitive to mosquito bites. But for those with severe allergies, symptoms can be more than just annoying: They can be serious. Most bites occur at either dusk or dawn, when mosquitoes are most active. While male mosquitoes are harmless — feeding only on nectar and water — female mosquitoes are out for blood.
A female mosquito locks onto her victim using a combination of scent, exhaled carbon dioxide, and chemicals in the person’s sweat. When she finds a suitable meal, she lands on an area of exposed skin and inserts her proboscis to draw the victim’s blood. The proboscis is the long, flexible tube extruding from her head, and it’s capable of piercing human skin. The common symptoms — a red bump and itching — aren’t caused by the bite itself, but by the reaction of your body’s immune system to proteins in the mosquito’s saliva. This reaction is also known as Skeeter syndrome.
