Rose geranium plants are traditionally used in South Africa to help repel mosquitoes. When the leaves and flower petals of the plant are bruised, they release a pungent odor somewhat like that of a rose. The odor is what keeps mosquitoes away. You can plant rose geraniums near the doorways and windows of your home to protect it from mosquitoes. Cut a branch from a rose geranium plant and hang it over a picnic table to repel mosquitoes while you are outside. Cut up some of the plant's leaves and pour hot water over them.
