Typically, the 100-400 eggs laid by a female only result in a few adults developing successfully. The adult stage appears in as little as 7-10 days in some mosquitoes. Adult behaviors vary depending upon the species. Some breed and live near water, which may be fresh or brackish. Other species may fly considerable distances from a breeding site to seek food sources.
Some species are only active at dusk, while others seek blood meals during daylight hours.
Only the females seek blood, which they need as a protein source to produce eggs. Males as well as females feed on flower nectar or plant juices for energy. There are many places mosquitoes can breed around homes. They need water for larval and pupal development and eggs must have water to hatch. Cesspools or septic tanks that have openings allowing females to enter and lay their eggs.
