This document provides instructions for making a natural mosquito repellent using 100ml of a carrier oil or cream base mixed with 20 drops each of citronella and lemongrass essential oils and 5 drops of thyme essential oil. It notes that for sensitive skin the lemongrass and thyme oils should be omitted, especially on the face, and more citronella used instead. The mixture is then ready to use to enjoy summer outdoors.
