When travelling abroad, mosquitoes can be a huge problem. Not only are they annoying, they also transmit disease. Malaria is the most common disease that they transmit, and is responsible for the deaths of 1 in 17 people currently alive. Also yellow fever, dengue fever and several forms of encephalitis can be transmitted to whomever the mosquito bites.
Expedition 50+ contains a dual action formula which combines natural pyrethroids with DEET to provide a high level of protection against biting insects in all environments. The natural pyrethroids act as a bite inhibitor, discouraging actual biting. Each application of Expedition 50+ will last for up to 10 hours. Re-application may be required in areas with high temperature and humidity.
