Don't count your chickens before they hatch. I'm not trying to jinx you but aphids are a bitch to get rid of. I'm glad you may have gotten them tho. The plant I'm having trouble with had been through the wringer. It is a Caribbean red I'm overwintering. Any way i thought i got rid of them too. I put the plant in a garbage bag and removed add much of the soil as i could from the roots. Then put it in the shower and completely washed the roots clean then hosed the hell out if it. There wasn't a bug left. I actually thought i killed it cause the leaves it had died. To my surprise it bounced back after being repotted for a couple weeks. I gave it more light and started getting lots of growth back along with the aphids. Wtf! Good luck bro!
