Mosquitoes arrive with the start of the rainy season. The rains that nourish plants help hatch mosquitoes, those little airborne blood suckers that cause irritation -- and sometimes disease -- when they bite. Mosquito eggs can survive in a dried state for years before being reactivated by water. Any outdoor place with standing water is a breeding ground for mosquitoes.
When a mosquito bites, it injects a bit of saliva to make the blood flow. It's that saliva that causes the itching and redness of a mosquito bite. Most of the time, irritation is all a mosquito bite will cause. People who have a sensitivity to mosquito bites also may have serious swelling. But mosquitoes also can transmit diseases like encephalitis, a potentially fatal disease that causes swelling of brain tissues.
