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

Lemongrass works for me. It is very affordable and easy to make. Just crushed them and put on your kid's room. Or you can buy lemongrass esential oil for room aromatheraphy. Beside lemongrass, i found several combination for natural mosquito repellants using esential oil. Hope it works for you.
