First I used a Neem Oil, water & alcohol. Then later when I saw more of them I came back with Bonide Systemic. I was surprised that they tolerated the spraying. I had 5 AV and 4 of them look fine one was in very bad shape after the Neem spraying for some reason I lost that one. I also sprayed the Streptocarpus and it is also doing fine and blooming. I wouldn't treat these unless I saw signs of some serious pest.
