The spot market for white spirit moves about once a month, so ICIS pricing reporters do not consider covering this market very exciting. Only now a reader of the New Scientist blog has inspired quite a debate because he has discovered a new use for white spirit: to attract flies. Blog readers who are keen to attract flies to their offices and kitchens should go long on white spirit because ... the "hydrocarbons (in white spirit) mimic insect hormones which the flies are attracted to for mating purposes." Another helpful reader of New Scientist writes on the blog that "flies in general LOVE white surfaces covered in black spots.. it will attract them from quite far with or without simulated hormone. They love to jump on the band wagon so to speak so are attracted to clusters of other flies."
