People with concerns over using chemicals to repel mosquitoes often turn to natural items that can keep mosquitoes away with low risk of poisoning. Ginger may somewhat reduce mosquito problems, but its effectiveness has no scientific support.
Repelling mosquitoes using ginger involves burning its plant materials and producing smoke that mosquitoes find unpleasant. Other plant materials that can keep mosquitoes away in this way include beetlenut and coconut husks.
The smoke from burning ginger plants can reduce the number of mosquitoes in an area, according to the University of Maryland Medical Center. Burning candles and other items produces carbon dioxide, which attracts mosquitoes and distracts them from pestering humans. However, no scientific evidence shows any benefit of burning ginger plants.
The smoke from burning ginger plant materials can irritate the eyes and lungs. As such, other natural repellents such as citronella candles can serve as safer alternatives.
