I’ve always been fascinated by natural ways to repel insects, especially flies, and one of the most effective methods I’ve discovered is using citronella. Citronella, derived from the leaves and stems of plants like citronella grass and citronella geranium, has a strong lemony scent that is surprisingly pleasant to humans but highly disagreeable to many insects. This simple, natural repellent has become a go-to solution for me whenever I want to keep pesky flies and mosquitoes at bay.
