Many have wondered why some people are covered in mosquito bites while others remain unscathed. Beyond causing red, sore, bumpy bites, mosquitoes also spread dangerous pathogens. According to the 2022 World Malaria Report, Nigeria bears the highest global malaria burden, with 27% of the global cases and 31% of malaria deaths. Nigeria also accounted for 55% of malaria cases in West Africa in 2022. So, what makes someone more attractive to mosquitoes?
1. Body Size and Breathing
Mosquitoes track their prey by scent, specifically carbon dioxide (CO2), which we exhale. Larger individuals exhale more CO2, making them more attractive to mosquitoes. Men, pregnant women, and adults typically get bitten more. Dr. Robert Jones from the London School of Hygiene & Tropical Medicine notes that body surface area and weight also play roles. Increased breathing rates, such as during exercise, also attract mosquitoes.
2. Natural Scent and Skin Bacteria
Our unique scent, influenced by genetics and skin microbiota, also affects mosquito attraction. Studies where people wore nylon strips to collect their scent showed mosquitoes have preferences for certain aromas. Genetic factors may account for up to 67% of mosquito attraction. Scientists are still researching which compounds attract mosquitoes and how to mask or reduce them.
3. Outfit Color
The color of your clothing can influence mosquito bites. Mosquitoes prefer red, orange, black, and cyan, while green, blue, and purple are less attractive. Avoiding colors that attract mosquitoes might reduce bites.
4. Blood Type
There’s a belief that blood type, particularly type O, makes someone more attractive to mosquitoes. However, studies are inconclusive, and Dr. Jones suggests blood type is likely not a significant factor compared to other elements.
5. Diet and Drinking
Some foods and drinks are believed to attract or repel mosquitoes. Garlic is thought to mask one’s scent, while salty or sweet foods may increase attractiveness. Beer might also attract mosquitoes, as a small study indicated. Dr. Jones advises using scientifically proven repellents rather than relying on diet changes.
Tips to Avoid Mosquito Bites
To minimize mosquito bites:
- Wear long-sleeved clothing and trousers.
- Use insect repellent.
- Keep windows closed.
- Sleep under a mosquito net.
- Be especially cautious during early morning and evening when mosquitoes are most active.
