My anti-mosquito candle is made with pure essential oils of Lemon Eucalyptus and peppermint. Products that contain oil of lemon eucalyptus, which comes from the gum eucalyptus tree, are a lot more effective than citronella and this candle can be used both indoor and outdoors. If burning outside be sure to keep it out of the wind to get the full burn time from your candle. Burn time is approx 60 hours. Remember to keep the wick trimmed and out of the sun. There is currently a 10 day delivery on this candle.
