Are there any natural mosquito repellents that one can make at home for the kids? I don't like the patches.

I learnt this trick from taxi-driver uncles. They always have pandan leaves in the car boots and apparently it is used to repel cockroaches. They told me it works for pretty much any insect so what I did was to blend the pandan leaves with some water and spritz this pandan juice in the rooms or even the clothes. It leaves a nice scent and keeps the insects at bay.
