The Asian tiger mosquito prefers to bite below the waist. Mosquitos lay from 100 - 300 eggs at one time. Most mosquitos lay all of their eggs at one time, in the same place. The Asian tiger mosquito, however, lays 3 or 4 eggs in many different locations, but only in tree holes or artificial containers that hold rainwater for at least 1 week. The normal hatching cycle of the Asian tiger mosquito is about 5-7 days, depending on water temperature.
Mosquito eggs can remain domant for a long time without contact to water.
However, if water reaches the eggs, it will trigger a reaction and the eggs then will hatch to become larvae. If the water level does not rise, the eggs will not hatch. Mosquitos bite animals, and can lead to heart worms in cats and dogs. Mosquitos build a resistance to pesticides.
