ClassX Video Lessons Why do mosquitoes prefer biting some people to others? – Big Questions – (Ep. 26)
Hi there! Have you ever wondered why mosquitoes seem to love biting some people more than others? Let’s dive into the reasons behind this itchy mystery and see if there’s anything we can do about it besides using bug spray.
Believe it or not, mosquitoes have their preferences, and about 10-20% of people get bitten more often. A big part of this is due to genetics. Around 85% of why mosquitoes like certain people comes down to their biology. This means that the way you smell and your genetic makeup play a huge role in attracting these pesky insects.
Our skin produces different substances that can attract mosquitoes. For example, people who produce more lactic acid, which is found in sweat, might get bitten more. Interestingly, mosquitoes seem to prefer sweat that has been on the skin for a while rather than fresh sweat. The bacteria living on your skin can also make a difference. People with fewer of these bacteria might not get bitten as much.
Your blood type might also influence how tasty you are to mosquitoes. Studies have shown that mosquitoes are twice as likely to land on people with Type O blood compared to those with Type B. Type A blood is even less attractive to them. Additionally, about 85% of people release a chemical on their skin that reveals their blood type, making them more appealing to mosquitoes.
Mosquitoes are attracted to carbon dioxide, which we all exhale. People who exhale more, like larger individuals and pregnant women, might get bitten more often. Interestingly, drinking beer can also make you more attractive to mosquitoes, possibly because it increases carbon dioxide production or body warmth.
You might have heard that eating bananas or taking Vitamin B-12 can keep mosquitoes away, but that’s just a myth. The best way to avoid bites is to use a good insect repellent, especially one with about 24% DEET, for the best protection.
Thanks for learning with us! If you have more questions, feel free to ask. Stay bite-free and see you next time!
Research and create a presentation about how genetics influence mosquito attraction. Include information on how genetic makeup affects body odor and susceptibility to mosquito bites. Share your findings with the class.
Conduct an experiment to observe how different skin substances affect mosquito attraction. Use safe, simulated environments to test how lactic acid and other substances might influence mosquito behavior. Record your observations and discuss the results with your classmates.
Conduct a survey among your classmates to find out their blood types and how often they get bitten by mosquitoes. Analyze the data to see if there is a correlation between blood type and mosquito attraction. Present your findings in a report.
Learn about how carbon dioxide levels affect mosquito attraction. Create a model or diagram to explain why people who exhale more carbon dioxide might attract more mosquitoes. Share your model with the class and explain your reasoning.
Investigate common myths about mosquito repellents and prevention methods. Create a poster that debunks these myths and provides scientifically-backed tips for avoiding mosquito bites. Display your poster in the classroom to educate your peers.

Hi, I’m Craig! Today, I’m going to answer a viewer’s question: “Why do mosquitoes prefer biting some people over others? Is there something we can avoid doing or do besides using repellent, like eating bananas?”
Well, you’re right that mosquitoes have preferences. About 10-20% of people tend to get bitten more than others, and there are a few possible reasons for this.
Experts estimate that around 85% of the reason mosquitoes prefer certain individuals is genetic, so it’s largely determined by your biology. Mosquitoes are particularly attracted to people with a specific combination of genetics and scent.
There are also substances on your skin that can attract them. For instance, individuals who produce more lactic acid, which comes from sweat, may experience more bites. Research has shown that mosquitoes are more attracted to sweat that has been on the skin for a day or two rather than fresh sweat. Additionally, the presence of certain bacteria on your skin can influence mosquito attraction; people with fewer of these bacteria may have less to worry about.
Blood type may also play a role. A study found that mosquitoes were twice as likely to land on people with Type O blood compared to those with Type B. Type A was even less attractive to mosquitoes. Furthermore, about 85% of people secrete a chemical on their skin that indicates their blood type, making them more appealing to mosquitoes.
People who exhale more carbon dioxide are also more likely to get bitten, which is why larger individuals and pregnant women may experience more bites. Interestingly, beer drinkers tend to attract more mosquitoes, possibly due to increased carbon dioxide production or body warmth after consuming alcohol.
Regarding your question about bananas, that’s actually a myth. Vitamin B-12 won’t deter mosquitoes either. Experts generally recommend using a standard insect repellent, ideally one that contains around 24% DEET for the best results.
Thanks for watching! If you have a question of your own, feel free to leave it in the comments below. See you next week!

This version removes any informal language and maintains a professional tone while conveying the same information.
Mosquitoes – Small flying insects that can carry diseases and feed on the blood of animals and humans. – Mosquitoes are known to spread diseases like malaria and dengue fever through their bites.
Genetics – The study of heredity and the variation of inherited characteristics in living organisms. – Genetics helps scientists understand how traits are passed from parents to offspring.
Biology – The scientific study of life and living organisms, including their structure, function, growth, and evolution. – In biology class, we learned about the different systems that make up the human body.
Skin – The outer covering of the body that protects it from the environment and helps regulate temperature. – Our skin acts as a barrier to protect us from harmful bacteria and viruses.
Substances – Materials with distinct properties that can be found in living organisms or the environment. – Certain substances in plants can be used to create medicines that help fight diseases.
Blood – The red liquid that circulates in the arteries and veins, carrying oxygen and nutrients to the body and removing waste products. – Blood is essential for transporting oxygen from the lungs to the rest of the body.
Type – A category or classification based on shared characteristics or qualities. – There are different blood types, such as A, B, AB, and O, which are important for blood transfusions.
Carbon – A chemical element that is a fundamental building block of life and is found in all living organisms. – Carbon is a key component of organic molecules, such as carbohydrates, proteins, and fats.
Dioxide – A compound consisting of two oxygen atoms bonded to one carbon atom, commonly found as a gas in the atmosphere. – Plants use carbon dioxide during photosynthesis to produce oxygen and glucose.
Repellent – A substance used to deter insects or other pests from approaching or settling. – Applying insect repellent can help prevent mosquito bites when spending time outdoors.
