Amy found out that most citronella candles don't contain even a bit of real citronella essential oil, but only a synthetically produced scent with none of the bug deterring benefits. She carefully whipped up her own batch using real citronella java essential oil (not the citronella oil sold for Tiki torches), and created her own jazzed up jars to give them some style. She used a little melted crayon for soft colors. Of course, you can skip the whole bug candle thing and just add some drops of your favorite scent to make delicious smelling indoor candles.
