It really works.
I bought Mosigiard for long-term use in the Solomon Islands which has Zika, malaria and dengue. It is the only natural repellent I've found that works in this level of the tropics. Electronic, citronella and other natural repellents did not work. Deet products worked but caused allergic and skin reactions over time. I am now a repeat buyer of MosiGuard and recommend it to all.
