Answer: Some species of mosquitoes lay their eggs on water or on vegetation very near to water because their larval instars are aquatic. Thus, when the eggs hatch the first instar larvae will already be in the larval media. Some species of Aedes mosquitoes lay their drought resistant eggs on the soil of dried up playa lake beds. When it rains, the moisture will serve as a hatching stimulus and the eggs will hatch and spend their larval instars in the pools of rainfall. Other mosquito female will lay their eggs in the water of plant axils, tree holes and related plant habitats. In each of these instances, the immature mosquito instars require water in larval development and molt into adult insects.
All mosquito eggs require some form of water to hatch. Some species of female mosquitoes lay eggs directly on the water, while others lay eggs in small depressions where water can collect. ... After exposure to water, most eggs hatch within 24-72 hours. Once eggs hatch, larvae emerge.
What you should do next is take the pieces apart using things like screwdrivers which would enable you to clean each part individually, as well as access new parts that are beneath.
