I think these citronella buckets are usless, we took one up north earlier this year, the top quater was coloured green & the rest was white like normal candle wax & did nothing to deter insects,the only success was the ones that were on a suicide mission & dived into the pool of liquid wax, the problem there was the liquid level would rise & drown the flame.It was win some loose some, wont buy them again.

Something that might be of interest. The GoLo shops down here in Vic have for sale Hurricane Lamps and you put Citronella Oil in to use. Supposed to get rid of mossies and about 9.99.
