I'm not into the chemical ingredients of all these nice/less nice smelling
baits, but I (and with me many others I adviced) add nowadays always a few
drops of Amyl-acetate (smells very nice) into my sugaring recipe. It
enhances significant the catch at the bait. I say always: Amyl-acetate makes
the difference. The recipe I use takes 5 minutes only to prepare. I mix 1/2
kg 'sirop the Liege', a thick mass (what is used on pancakes) with one cup
of simple sirup (= 1 part boiling water, 2 parts sugar). This untill the
mass is liquid enough to spread with a brush. In this I mix beer (and drink
the rest of the bottle myself). Then I add a few drops of Amyl-acetate to
some 20 ml of ethanol (or Rhum, or Wodka, or wathever available, even cheap
desinfectant alcohol works fine). I mix this solution into the mixture and
it is ready for use. 
Hope this helped a bit.
