Why Do Mosquitoes Bite Some People More Than Others?

Key Points:

• Mosquitoes are more attracted to certain people due to factors like blood type, with those having Type O blood nearly twice as likely to be bitten as those with Type A, possibly because of secretions signaling blood type.
• Carbon dioxide output, lactic acid released through the skin, body heat, and clothing color influence mosquito attraction, with higher metabolic rates, exercise, alcohol consumption, pregnancy, and being overweight increasing risk.
• To prevent bites, experts recommend avoiding peak mosquito activity times at sunrise and sunset, wearing breathable long clothing, and using insect repellents containing about 5% DEET, which is effective and safe when used properly.
• Natural repellents like citronella candles lack scientific support, while fans or breezy areas can deter mosquitoes by disrupting their flight; if bitten, scratching should be avoided to prevent infection, and relief can be obtained using ice, topical steroids, or antihistamines.
• Prevention remains the best strategy for enjoying outdoor activities during mosquito season, with lifestyle adjustments and protective measures helping reduce the likelihood of bites and associated discomfort.
