Throughout the United States home improvement stores and garden centers market the citronella plant as an effective mosquito and bug repellent. believing this claim is understandable as the plant seems to have a strong citronella odor. However a 1996 study confirmed the citronella plant does not repel mosquito’s. The authors concluded “There was no significant difference between citrosa-treated ( citronella plant ) and nontreated subjects.” Fortunately there are other plants that have been shown to repel bugs. Gardner’s call these companion plants.

Once the plants and human subjects were in place mosquitoes were released in the hut. The researchers concluded that the some of the plants believed to repel bugs did reduce the number of mosquito bites. The plants that provided the most benefit were Lantana, Fever Tea, and Lime Basil. Its important to note these were live plants, not oils or incense.
