Actually if you know what to look for you can take some preventative action. The leaf rollers actually sew the leaf so it can't unfurl. When I see evidence of them I'll go around in the evening with a knife and cut the threads along with spritzing some insect killer in the unfurled leaves. If you're not adverse to chemicals, Bayer advanced works really well in controlling them .. you just apply it every 6 weeks.
