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

Lemongrass indeed! It's economical and very easy to find. Aside from that, you can also use cinnamon oil. There have been studies that notes cinnamon oil can also rid of mosquito eggs! However, do not apply it directly onto skin as it might cause irritation. Instead, use it as aromatherapy at home. I also find this amazing idea on pinterest which you can easily make at home. And it is also pretty! You can make this as decor if you have an outside party. Just always always be cautious to keep these out of reach of kids. https://www.pinterest.com/pin/455567318537081953/
