Citronella as a Mosquito Repellent

Citronella grass is indigenous to South America. The oil derived from the plant is called geraniol and is the active ingredient in many natural mosquito repellent products.

Types

• Citronella is used in mosquito repellent sprays and lotions. While it is nontoxic, a few people experience a mild skin rash with frequent use. Citronella is also used to scent candles, outdoor lanterns and tiki torches. The characteristic strong, citrus smell repels mosquitoes.

Benefits

• Citronella oil is plant-based and nontoxic. DEET is a poisonous mosquito repellent and pesticide. While DEET is the most effective ingredient in sprays and lotions, many do not want to use the toxic product. Citronella-based lotions and sprays do not work as well as or kill mosquitoes like DEET, but citronella does repel mosquitoes.

Effects

• The strong scent of citronella confuses insects such as mosquitoes and fleas. The citronella aroma masks the odor of humans and animals so that the bugs cannot find targets to bite.
