Crepe Myrtle Trunk Insects: Aphids or Transient Bugs?

Grouped Black Winged Insects on Crepe Myrtle Trunks

20 crepe myrtles have oval patches of black rice-grain insects that grow wings and regroup. Most likely aphids (winged forms).

Check

Look under leaves for green soft-bodied aphids—that’s where damage occurs.

Control

If aphids confirmed: Bayer Advanced Tree & Shrub Insecticide soil drench per label. Systemic, kills in week, protects 8 months. Only crepe myrtles affected.

If Not Aphids

Transient insects causing no harm. Monitor.
