What Are the Dangers of Burning Citronella Candles Indoors?

Citronella oil has been determined by the EPA to be a safe substance. It is commonly used in candles to repel bugs outdoors. When burned indoors, it can cause problems in people who are susceptible to health problems from scented candles.

Types

Citronella candles are a variety of scented candle. In reviewing data from Toxline, the National Candle Association, Medline and the American Chemical Society, the EPA has stated that burning scented candles has resulted in an increase in health problems in some of the studies conducted by these organizations, while showing no health risks in others.

Risks

An American Chemical Society study that showed scented candles to be harmful to the health when burned indoors found that the soot created by burning candles can penetrate deep into the lungs of those who are around them.

Considerations

The EPA did find that scented candles give off more soot than unscented candles and recommended that unscented candles should be burned indoors. Citronella candles are dependent on their scent to repel bugs.

Misconceptions

According to the EPA, many of the worst health risks of burning candles have been attributed to lead wicks, which are no longer made in the United States. Imported citronella candles may contain those wicks, the EPA said in a 2001 project summary.

Warning

Indoor air that has soot particulates in it can aggravate asthma and other lung conditions.
