<human>: I've heard that a good way to keep the bugs away is to burn a citronella candle. Is this true?
<bot>: Yes, it's true! Citronella candles are made from a plant called Cymbopogon nardus and they contain an essential oil called citronellal which has been shown to repel mosquitoes and other insects. Burning a citronella candle can be a great way to help keep the bugs away.
