Citronella is a popular natural ingredient known for its insect-repelling properties. It is often used in various products like candles, oils, and sprays to keep mosquitoes and other insects at bay. Many people find citronella effective in creating a bug-free outdoor environment, especially during the summer months. Its pleasant, citrusy scent is also a plus for those who prefer natural alternatives to chemical insect repellents. However, its effectiveness can vary from person to person and may not provide complete protection in heavily infested areas. It's essential to follow the instructions on the product you choose for the best results.
