Lemongrass for Mosquito Control: Not Hardy, Not Effective as Landscape Plant

Lemongrass (Cymbopogon citratus) isn't winter-hardy north of Atlanta, and even where it survives, it doesn't repel mosquitoes as a landscape planting.

The Science

Repellent oils are in the leaves but require crushing and direct skin application to work. Intact plants release negligible volatile compounds.

Better Alternatives

CDC-recommended repellents with oil of lemon eucalyptus or picaridin provide reliable, science-backed protection. Plant lemongrass for culinary use, not pest control.
