One of the major irritations of a Japanese summer, besides the current humid heat, is getting eaten alive by the tiny armies of mosquitoes, indoors or out. While most people resort to spraying on DEET, a growing number of mothers concerned about the effects of this potent chemical on their children’s delicate skin are now making their own aroma mushiyoke (aroma insect repellent) out of essential oils.
The trend, according to Tokyo Walker, has been spreading by word of mouth among mothers who are looking for natural alternatives. The magazine interviewed a housewife who began making her own insect repellent after becoming a mother two years ago. She favors a refreshing lemongrass spray that can be not only applied to the skin, but also sprayed onto cloth in her baby stroller to keep insects at bay.
Aromatherapy has been popular for a few years in Japan, so the essential oils used to make these sprays are readily available in the shops. To make a lemongrass spray you need extract of lemongrass oil, ethanol and water. Three to five drops of the essential oil should be mixed with 5 ml of ethanol and 45 ml of water. The whole thing is then shaken vigorously and put into a plastic spray bottle (easily bought in ¥100 stores). Unlike commercial citric sprays, the lemongrass is not overwhelmingly pungent, so the mixture can be sprayed on screen doors or curtains to keep out insects without overwhelming the room with the smell. Geranium and lavender essential oils can also be used for a similar effect.
