A natural mosquito and insect repellent typically blends plant-based ingredients like lemon eucalyptus oil, lavender, citronella, or neem oil—all known for their bug-repelling properties. These repellents are free from harsh chemicals like DEET and are often mixed with carrier oils or witch hazel for safe skin application. They offer a gentler, eco-friendly way to keep pesky insects at bay while soothing the skin with calming botanicals.
