📖 Read the story
Do mosquitoes bite you a lot? Some people get many bites, but others do not. Scientists now know why this happens. Every person has a special smell on their skin. This smell comes from tiny things called bacteria. Scientists in Florida studied three types of mosquitoes. More than one hundred people helped them. These people put their arms into a machine. The mosquitoes could smell the people, but they could not bite them. The scientists watched which people the mosquitoes liked. This work is very important. Mosquitoes can carry diseases and make people sick. If we know which smells mosquitoes like, we can make better sprays. These sprays will keep the insects away. Then, everyone can stay safe and healthy when they play outside. Do you get many mosquito bites in the summer?
