Just a quick line to let you know how impressed we were with the Mosi-guard Natural® insect repellent. We used it on our Nile cruise holiday and none of us were bitten. I loved the fresh smell and it wasn’t sticky when applied. Joe, our son, also used it on his trek across the Atlas Mountains in Morocco, spraying it on the tent as well as himself with great success, and no bites reported.
