The power of citronella
If it is not used in excessive quantities, citronella is a natural and harmless essential plant oil. Citronella is obtained from the grass varieties Cymbopogon nardus and Cymbopogon winterianus. These types of grass grow predominantly on Java, Haiti and in Central America. Because of its insect-repellent qualities, the oil is used in citronella candles, lamps, sprays and lotions.
For some 50 years now, citronella has been the most commonly used method for holding mosquitoes and other insects, such as fleas, at bay. This works because citronella emits such a strong aroma, one that the insects do not find pleasant.
