Mosquitoes are spreading to new areas due to climate change, and they are becoming harder to kill with normal bug sprays. Scientists made a special fungus that smells like a sweet flower. Mosquitoes fly towards the smell to eat, but when they touch the fungus, they get sick and die. It is very cheap to make, safe for humans, and lasts for months. This helps protect people from diseases like malaria and dengue in a natural way.
