While DEET based mosquito repellents are by far the most popular option amongst travellers, some people aren’t comfortable with using chemicals on their skin. This means many travellers are often on the look out for a more natural, DEET-free option, when it comes to choosing a mosquito repellent.
The most common ingredients used in DEET-free mosquito repellents include Saltidin and PMD (Citidiol/Oil of Lemon Eucalyptus), which are much kinder to the skin and are often safer to use on children compared to DEET.
For travellers who are visiting areas with a high risk of tropical disease, Saltidin based repellents (20% concentration or higher) are the best DEET-free alternatives available. While PMD based repellents are also effective in repelling mosquitoes, their strength and the duration of protection is more comparable with lower concentrations of DEET, making them better suited to use in areas that don’t pose a risk of insect-borne disease.
