Are you a mozzie magnet?

Ever been out enjoying a barbecue or a picnic, only to find yourself swatting away mosquitoes while everyone else seems untouched? Here’s why they just can’t resist some people - and what you can do!

It’s all about your scent

Mosquitoes have an incredible sense of smell, and they use it to find their next meal. They’re drawn to carbon dioxide, which we all exhale when we breathe. But here's the catch: some people produce more CO2 than others. Larger people and those who are more active tend to breathe out more CO2, making them prime mosquito targets. If you’ve ever gone for a run or workout, don’t be surprised if the mozzies show up right after.

But it’s not just about breathing! Mosquitoes are also attracted to certain chemicals on your skin, such as lactic acid and ammonia. These compounds can vary due to factors like genetics, meaning some of us are just born with that 'perfect' scent that mosquitoes can’t resist.

Heat, sweat, and mosquitoes

When the weather’s warm and you’re sweating, it’s like you’ve set up a 'dinner is served' sign for mosquitoes. They’re excellent at detecting heat, so the combination of your warm skin and sweat makes you super attractive to them. 

Does blood type matter?

Some studies suggest mosquitoes are attracted to people with certain blood types. In particular, those with Type O blood might find themselves getting bitten more often than those with Type A. So, if you’ve always joked that you have 'sweet blood' and you’re Type O, turns out there may be some truth to it!

Fashion choices can make a difference

Who knew that your wardrobe could impact your mosquito appeal? Mosquitoes have pretty sharp eyesight and are attracted to dark colours - so if you’re wearing dark blue or black, you might be turning yourself into a mosquito magnet. Lighter colours, on the other hand, are less attractive to mosquitoes and can help you avoid becoming their next snack.

Beer lovers beware

Research shows that drinking alcohol, especially beer, can make you more attractive to mosquitoes. While the experts are not entirely sure why this happens, it might be because mosquitoes just appreciate your taste in beverages!

How to keep the mozzies at bay

  • Repellent is your friend: Repellents with DEET*, picaridin, or oil of lemon eucalyptus are your best defence against mozzies.

  • Natural ways to keep the mozzies away
  • Cover up: Wear lightweight clothing and covered shoes to protect your skin. Mosquitoes will have a harder time getting to you. 

  • Set up defences: Use citronella candles or mosquito coils when dining outdoors. Just make sure you're sitting close by for them to work.

  • Avoid peak mosquito hours: Dusk and dawn are the times when mosquitoes are most active, so try to stay indoors during these hours if you can.

  • Sit near fans – mosquitoes can't fly in the wind.

  • Don't bother with sonic devices or repellent wrist bands, as the general consensus is that they are pretty useless!

  • Remove stagnant water in anything from gutters to pot plant drip trays - mosquitoes only need a millilitre of water or so to breed in.

* DEET has been widely used in insect repellents since the 1950s and remains a safe, effective active constituent when used according to the label instructions: health.wa.gov.au
