With these insect repellent bracelets, your loved ones can spend more time outdoors during the summer or while traveling in tropical countries with high humidity where mosquitoes such as Anopheles, the vector of malaria, are numerous. Extended diffusion technology allows for slow, steady diffusion of essential oils for optimal protection for up to 300 hours so you can enjoy your outdoor activities without worries. You can therefore use the bracelet 24 hours a day to avoid bites. For best results, wear it on both your wrist and ankle. After use, store the bracelet in an airtight container to delay the emission of odors and prolong its use.
