- Common myths like “sweet blood” are not scientifically supported.
- Effective prevention includes using EPA-approved repellents, wearing protective clothing, managing environmental conditions, and seeking professional mosquito control services when necessary.

Mosquitoes Do Have Favorites
It might sound strange, but mosquitoes are surprisingly picky eaters. Around 20% of people attract way more mosquito bites than others. But why is this happening to you specifically? Let’s look closer at the biology and environment mosquitoes find irresistible.

1. You’re Breathing Out Too Much Carbon Dioxide Mosquitoes have a superpower—they can detect carbon dioxide from far away. More prominent people, athletes, or anyone just finishing working out produces more COâ‚‚. Pregnant women and adults, in general, exhale more carbon dioxide, making them prime mosquito targets. Have you ever noticed mosquitoes swarming around your face? That’s following your breath. 2. You’re Giving Off a Lot of Heat Mosquitoes are tiny heat-seeking missiles. If you naturally run warmer or have been active, your increased body temperature makes you a flashing neon sign for mosquitoes. Especially on those warm summer evenings, they’ll spot you easily and zoom straight in. Imagine yourself glowing brighter to them every time you sweat—kind of annoying, right? 3. Your Body Has That “Special” Odor Do you know how everyone has their own unique scent? Well, mosquitoes do, too, and they’re experts at sniffing out particular odors. Your skin’s bacterial makeup plays a massive role here. Certain bacteria produce chemicals like lactic acid, ammonia, and carboxylic acids—mosquito magnets. You will be their favourite meal if your microbiome creates more of these chemicals. Honestly, it’s a bit unfair how your natural scent could betray you like this. 4. Mosquitoes Are Blood Type Snobs Believe it or not, mosquitoes have favorite blood types. Studies consistently show that folks with Type O blood attract almost twice as many mosquitoes as those with Type A or B blood. Mosquitoes literally sniff out blood type through chemicals on your skin. Crazy, right? So, if you have Type O, mosquitoes might see you as the tastiest snack on the block.

Wait, What About “Sweet Blood?”
There’s a common myth that mosquitoes prefer “sweet blood,” but honestly, it’s just an old wives’ tale. Mosquitoes bite humans because they need protein from our blood to reproduce. They get sugar from plants, not us. So, mosquitoes aren’t choosing you for dessert, no matter how much cake you eat. But, let’s be honest—it’s still annoying to be a frequent snack.
Okay, How Do You Stop Them From Biting You?
- While changing your blood type or natural body chemistry isn’t an option, thankfully there are practical steps you can take:
-
Stick to EPA-Approved Repellents: DEET, picaridin, or oil of lemon eucalyptus are your best friends outdoors.
-
Pick Clothes That Protect: Long sleeves, long pants, and lighter colors can drastically reduce bites.
-
Stay Cool and Calm: Mosquitoes love warmth and carbon dioxide—avoid intense activity during their peak hours, typically dawn and dusk.
-
Skip Strong Fragrances: Floral perfumes or fruity deodorants might smell great to you, but they attract mosquitoes.
-
Get Rid of Standing Water: Even a tiny amount can be a mosquito nursery. Regularly empty buckets, flower pots, or gutters to disrupt their breeding cycle.
-
Use a Fan Outdoors: Mosquitoes are notoriously weak fliers. Even a gentle breeze from a fan can keep them at bay.
-
Bring in the Pros: Professional pest control treatments can dramatically reduce mosquito populations if mosquitoes are ruining your summer.
