| The smoke and smell of dung fires is a characteristic part of life in south Sudan. The smoke repels the biting flies and mosquitoes that irritate and spread disease. When biting flies are particularly bad, cows will voluntarily return from grazing to stand in the comfort of a dung fire's smoke. The ash from dung fires also repels insects and is antiseptic so is used as a wound dressing. | ||||||||||||
