Say goodbye to mosquito bites: the science

Key Points:

• Mosquito attraction is largely determined by the chemistry of your skin, specifically carboxylic acids influenced by genetics and your skin's microbiome, making some people consistently more attractive to mosquitoes than others.
• The most effective way to prevent bites is using EPA-registered repellents containing DEET or picaridin applied after showering, as these have strong and reliable evidence supporting their efficacy.
• Avoiding floral and fruity scented soaps, perfumes, and lotions in the evening can reduce mosquito attraction, since these fragrances mimic plant scents that mosquitoes favor; using plain coconut-based soap and rinsing off sweat also helps.
• Common myths such as eating garlic, taking vitamin B, wearing repellent wristbands, or using bug zappers have little to no proven effect on preventing mosquito bites, while citronella candles offer minimal protection only in still air nearby.
• While you cannot fundamentally change your personal scent that attracts mosquitoes, adopting a fragrance-free evening routine and proper repellent use can significantly reduce the likelihood of being bitten.
