Nearly everyone is sensitive to mosquito bites. But for those with severe allergies, symptoms can be more than just annoying: they can be downright 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. The females of the species are out for blood.

The common symptoms of an allergic mosquito bite - a tell-tale red bump and itching - aren’t caused by the bite itself, but by a reaction of the body's immune system to proteins in the mosquito's saliva. In case of doubt always consult a doctor.
