Answer

Aedes mosquito species have adapted well to human habitation, often breeding around dwellings in small amounts of stagnant water found in old tires or other small containers discarded by humans. Even a bottle cap filled with water can serve as to incubate and hatch Aedes eggs. Eggs can survive periods of drying and will hatch when exposed to water. Humans are the preferred hosts.

Female Aedes mosquitoes are daytime feeders. They inflict an innocuous bite, usually on the back of the neck and the ankles, and are easily disturbed during a blood meal, causing them to move on to finish a meal on another individual, making them efficient vectors. Not uncommonly, entire families develop infection within a 24- to 36-hour period, presumably from the bites of a single infected mosquito.
