The mosquito life cycle can be disrupted by eliminating stagnant water, treating it with larvicides like kerosene, and using insect repellents. Additionally, introducing natural predators such as fish can help reduce mosquito larvae and break their developmental stages.
Mosquito larvae and pupae come to the water surface to breathe. Larvae have a siphon tube to extract oxygen from the air, while pupae need to reach the surface to allow adult mosquitoes to emerge and fly away.
