Lemongrass
Citronella is the natural oil present in lemongrass and it’s a popular natural insect repellent.
Citronella candles and insect-deterring products are therefore very popular. This ornamental can reach a height of up to four feet in one season only.
According to studies, its repellent effects against A. culicifacies, a mosquito species, are 100 percent.
Another lemongrass type that’s also a great insect repellent is citronella grass. Plant it in a pot or in the soil in an area that is sunny and well-draining to keep insects at bay.
Rosemary
The oils of rosemary are praised as highly effective in the fight against insects. You can make a natural repellent using a quart of dried rosemary combined with a quart of water and leave it to steep for half an hour.
