thanks for posting back, i will try that method and see how it goes last time i used a bit of dish soap in my water it kinda burnt the leaves so i will give it a miss this time round.
the bottle of neem oil i got is only 100ml but its definatly had some effect on them. i have noticed that they have moved away from the older leaves and onto the newer leaves where i asume there is no neem oil (because they are new leaves) so i now keep spraying the new leaves in hope they will finally just give up and go away
