The sevin probably did the job, but just keep an eye on them. I'm OWing 3 plants(2 pubescens and a chinense). I trimmed them back, root pruned, rinsed them and rinsed off old soil, potted them up with a new bag of mix(MG), and still got a hatch-out of aphids. I tried putting ladybugs on them(the ones that are coming in for the winter), but they were not interested, so I sprayed the plants with Safer insecticidal soap(after moving the LBs). I'll keep doing that weekly until I no longer see aphids. Let us know how it goes with yours.

Thanks for the info. I will keep you posted. It has been inside for about two weeks now and no sign of aphids.
