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.
You can learn even more about mosquitos at the American Mosquito Control Association website. Every type of breeding habitat is continuously monitored for species type, time of emergence, and size of population. This information is recorded in a database, which contains extensive information about each species and when to expect each particular species. Surveillance helps Operation Services determine the most effective method of controlling the mosquito population. Aerial spraying is done only in emergency situations.
