How Natural Mosquito Repellents Work
Many mainstream insect repellents can contain DEET (N,N-Diethyl-m-toluamide) or picaridin (hydroxyethyl isobutyl piperidine carboxylate). If you are looking to avoid these chemicals, there are a range of natural alternatives to you can try.
Why do some people get bitten more than others?
No one likes an itchy bite, and if you're more susceptible than others, you'll want a mozzie repellent that works. Why are some people a mozzie's dream meal when others are left alone? The smell you emit to mosquitoes may entice them to land on you. Your natural scent can attract mosquitoes, plus some fragrances and deodorants. Mosquitoes can also sense the carbon dioxide you breathe out, as well as your body temperature (warmth) and humidity 1. Since you can't really change your breathing, scent, or body temperature, all we can do is try to mask your location, or use sprays to deter this little pests.
Do natural and chemical based repellents work differently?
Bug repellents work by masking these chemical giveaways that entice mozzies to head your way. You'll find most mainstream insect repellents contain DEET (N,N-Diethyl-m-toluamide) or picaridin (hydroxyethyl isobutyl piperidine carboxylate) 2. But there are natural alternatives to seek out, which don't use these chemicals.
Active ingredients in natural mosquito repellents
We've all used something with citronella in it – traditionally used as an anti-bug scent, but oil of Lemon Eucalyptus (also known as PMD) has been shown to be a very effective repellent 3 and comes from a natural source. It is a by-product of the essential oil of lemon-scented gum, and is an ingredient endorsed by the Centres for Disease Control and Prevention in the USA. Other essential oils such as lavender, cinnamon, thyme, catnip oil 4 can help to ward off unwanted critters, and smell far nicer than the usual chemical sprays. Of course, these natural alternatives only deter creepy crawlies, rather than poisoning them.
