I have also used a Pyrethrum (or is it Pyrethrin ??) spray with great success.
When I first had an aphid attack a couple of years ago I tried removing them by
squashing with fingers and with tweezers, but I could never get them all. I
lost my biggest D. Capensis and had them spread to many of my other plants
before I tried the spray. After a couple of weeks the aphids were all gone,
any the plants didn't seem to mind the spray.
