A while back, a friend gave me some chilli plants. Sadly, they came with free aphids. I've tried moving the plants outside, bring them in with a ladybird on, and a fruit-and-veg bug-killer spray (which contains Pyrethrum). There are still aphids. They had a bit of a field day while I was away, but while spraying seems to kill most (all?) of the obvious aphids, if I wait a few days, they appear again.

I'm not quite sure what to do - should I try spraying more often even if I can't spot any aphids in the hopes that'll kill any small ones before they reproduce, or move on to other approaches? To be honest, I'm less looking for control and more for maximum deletion, as the Cybermen would say...
