Little beasties!! - I thought they were dust - but on closer inspection they are teeny tiny little things, about this size -> . <- are all over my windowsill, I have my pot plants on there. I have a miniature rose, a money plant, a very ill orchid, 2 little flat leafed things and one tall bushy one with thick fleshy stems, has pale and dark green striped leaves. So how do I get the beasties to leaf leave ?!
