Does a mosquito lay eggs in the water?

Yes, mosquitoes lay their eggs in water. Female mosquitoes need a blood meal before they can lay eggs, and they use the blood to produce the proteins that are necessary for egg development. After taking a blood meal, a female mosquito will find a suitable body of water to lay her eggs. She will typically lay her eggs in shallow, stagnant water, such as puddles, ponds, or swamps. The eggs will hatch into larvae, which will then grow into pupae. The pupae will eventually emerge from the water as adult mosquitoes.
