Crepe Myrtle bark scale has become a real issue in Hampton Roads, affecting our beloved Crepe Myrtle tree. Virginia has now joined the ranks of 12 other states in which this insect is unfortunately found.
Large infestations are easy to identify, as this is the only bark scale in the U.S that impacts crapemyrtles. Not to be confused with a heavy aphid infestation, crepe myrtle bark scale will also result in the occurrence of black sooty mold on the surface of the tree’s bark. Other identifying factors include small, Q-tip like white/light gray spots on trunks and small twigs, which are actually part of the female insect, under which the pupae grow. To treat, we recommend Fertilome Systemic Insect Drench.
