All species of mosquitoes share one thing in common when it comes to where they prefer to lay their eggs: it is in or near a stagnant water source.
Some species of mosquito lay their eggs directly in the water, while others lay their eggs on the surface of the water, and others prefer to lay their eggs on plant matter that rests on top of the standing water source.
Because mosquito larva and pupa spend almost all their time developing in water, it is crucial that the mosquito eggs are laid in a location that will be conducive to their development.
Each stage of the immature mosquitoes lifecycle, including the egg stage, last for about four days to two weeks, depending upon the species of mosquito.
