 That's what keeps it from coming back. That's not a normal thing that should be happening to crepe myrtles. There may be some crepe myrtles out there. You know, they're all hybrids. There may be some of them that have more of a built-in weakness than others. It would be a little bit more prone to having the problem. But in any case, it can be solved. You can kill the scale with crepe.
