Mosquitoes have been around for over 210 million years. They lay eggs in water that hatch into larvae and pupae, which mature in water before emerging as adult mosquitoes. Female mosquitoes require blood meals to develop eggs and are responsible for transmitting deadly diseases like malaria. Though they have a short lifespan of around 2-3 weeks, female mosquitoes can lay up to 300 eggs at a time, making mosquito prevention and control important. Effective methods include removing stagnant water, wearing light-colored clothing, using mosquito nets, and practicing good sanitation.
