This Uncle Harry’s citronella oil is the natural insect-repellent foundation ingredient. Steam distilled from Cymbopogan nardus (Sri Lankan citronella grass), the 100% pure oil delivers the same compound used in commercial mosquito-repellent products — but without the synthetic carriers and propellants that fill aerosol citronella sprays.
The most common use is making natural DIY insect spray: dilute citronella oil with carrier oils (almond, coconut, jojoba) at appropriate ratios and spray on skin or clothing for outdoor use. The oil also blends naturally with sandalwood, bergamot, and geranium oils for layered insect-repellent recipes. Beyond insect repellent, citronella works in aromatherapy diffusers as a fresh, earthy, energizing scent, and in homemade candles and soaps for the same effect.
The 0.5 fl oz size is the standard essential oil bottle — enough for many DIY insect-spray batches, multiple candle or soap projects, or extended diffuser use. For households committed to natural pest control over commercial DEET-based products, this is the foundation ingredient. USA made. Lehman’s catalog selection.
