Mosquitoes live four to eight weeks. All female mosquitoes lay eggs in or around water. After being flooded with water, the eggs hatch into larvae and take about seven days to develop into adults. At the water surface, the larva changes to a pupa before emerging as an adult mosquito. You are probably most familiar with the mosquitoes you see when you are outside, particularly if you go into tall grassy areas or heavily vegetated areas.
Mosquitoes also prefer being active on days that are calm and humid.
They are most active near sunrise and sunset. Larval mosquitoes can be found in standing water. Depending upon the type of mosquito, larvae can be found in ditches, woodland pools, small stagnant ponds, and unkept birdbaths - anything that holds water for more than a week. Controlling mosquitoes in your backyard You can control mosquitoes around your home and neighbourhood by eliminating standing water. Several hundred mosquitoes can breed in a small amount of water.
