About Lemon Eucalyptus and Insect Repellent

Lemon Eucalyptus is unique among plant-based essential oils in that the US CDC specifically recommends it (or its derivative compound PMD) as effective against mosquitoes carrying serious diseases. Most plant-based insect repellents (citronella, lemongrass, others) provide shorter protection durations than DEET-based repellents. PMD - a chemically refined derivative of Lemon Eucalyptus - provides protection durations comparable to DEET (4-8 hours) while remaining plant-derived. The raw essential oil is less concentrated than commercial PMD products but still provides meaningful repellent effects.

How to Use Lemon Eucalyptus Essential Oil

Insect repellent spray: 20-25 drops in 2 oz of carrier (water with alcohol to dissolve, or witch hazel water); spray on exposed skin. Diffusion: 3-5 drops in a diffuser. Topical blending: dilute to 1-2% in carrier oil. Important: PMD-containing commercial products are typically more effective than raw essential oil for serious mosquito protection.

Safety Information

Not recommended for children under 3 years old (CDC guidance). Standard essential oil precautions apply: dilute before topical use, patch test, keep out of reach of children.
