this might sound disgusting but try putting a blob of jam on top of mature chedder cheese, it is brill, honestly. other than the usual victoria cakes etc I am not sure what else you can do, Mind you its handy to keep in case you get overrun with ants in the summer, because I read somewhere that if you put a trail of jam leading away from your house, and a saucer of jam at the end of the trail then the ants will be attracted to the saucer therefore diverting them away from your house!!! luckily I have not had the need to try this, but it does sound feasible. sorry I have not been able to help you further.
