Why Some Maltese Are Mosquito Magnets

Malta’s humid climate and abundant water sources make us no strangers to mosquitoes. But why do some of us become mosquito magnets, while others seem immune? Let’s look the science behind these tiny tormentors and find out what makes us so appealing.

Believe it or not, mosquitoes have a preference when it comes to blood types. Studies have shown that they’re particularly fond of Type O. If you’re an O negative, like around 44% of Maltese, you’re more likely to attract these pesky critters. But why?

Mosquitoes use a combination of factors to zero in on their target, including body heat, carbon dioxide, and scent. People with Type O blood release a certain chemical that mosquitoes find irresistible. So, if you’re enjoying a sunset stroll along the Sliema Promenade and suddenly find yourself swarmed, it might not just be bad luck.

Our body chemistry plays a significant role in attracting mosquitoes. Certain chemicals in our sweat, like lactic acid and ammonia, act like a beacon to these insects. People who produce more of these compounds, or who have a stronger body odour, are more likely to be targeted.

Mosquitoes are also drawn to specific scents. For instance, they’re attracted to the smell of certain perfumes and cosmetics. So, if you’re rocking your favourite Chanel No. 5 while sunbathing at Golden Bay, you might want to rethink your fragrance choice.

Mosquitoes are excellent at detecting carbon dioxide, which we exhale with every breath. The more CO2 you produce, the more likely you are to attract mosquitoes. This is why pregnant women, who have higher CO2 levels, often find themselves with more mosquito bites.

Being overweight or exercising vigorously also increases CO2 production, making you a more attractive target. So, if you’re puffing and panting after a gruelling session at the gym, don’t be surprised if you’re swarmed on your way home.

First, accept that you’re a tasty treat and plan accordingly. Wear long sleeves and pants, use insect repellent, and avoid being outside at dawn and dusk, when mosquitoes are most active. If you’re heading to a beach or park, consider wearing neutral scents or fragrance-free products.

And remember, it’s not just about you. Mosquitoes can carry diseases like West Nile virus and Zika, so protecting yourself helps protect everyone. So, next time you’re out enjoying Malta’s beautiful sunset, take a moment to appreciate the science behind the swarm. And maybe, just maybe, consider switching to a less appealing blood type.
