You can try picking them off by hand or using a Drosera leaf
to sweep them off. While this is time consuming and may not be 100%
effective, it is also the least harmful method for getting rid of
aphids.
While some people have suggested dunking the plant in water for
a few days, I have found this method to be ineffective except for
plants such as the terrestrial Utrics.
Pesticides can be extremely effective, but are also the hardest
on the plants. Try malathion (if you can get it), or Diazanon. I've
used Diazanon on most cp's. The biggest drawback is that the stuff
I have is oil based, and so strips the sundews of their mucilage.
Finally, with plants like capensis and filiformis that have
large root systems (if they're older, established plants), I'll
often just chop off the affected tops, and let the plant come
back from the roots. This also works well for any other thick
rooted sundew.
Good luck!
Chris
