Thanks for the info I think that I am going to have to bring in the 'nasties' as the infestation is severe :( Probably need to think along the line of a systemic applied very often for a few times and then maybe things will be back to a manageable level where I can use an alchohol/water mix to spot spray. Will have to rug up like I am about to take a space walk to do it though :( About ready to consign the lot to the rubbish skip actually.
