Finding Natural Predators of Crapemyrtle Bark Scale

Crapemyrtle bark scale is a type of soft scale insect that feeds on plant sap. These insects (in their adult stage) have a fluffy white waxy covering, and they are typically found on the branches, bark, and/or around pruning cuts. Crapemyrtles are their preferred host plant, but they can also feed on other plants, including American beautyberry, apple, and boxwood. A byproduct of their feeding is a sticky substance called honeydew. Sooty mold can grow on the honeydew, giving the bark and branches a blackened appearance. This pest was first detected in Maryland in 2020. There are several natural predators (beneficial insects) that are helping to control this pest naturally. In 2024, University of Maryland Extension (UME) faculty observed that many populations of crapemyrtle bark scale were collapsed or seriously reduced, seemingly by natural predator activity. Here, Sheena from the UME commercial horticulture team, talks about some of the natural predators she has been observing. The larval stages of lacewings, syrphid flies, and lady beetles all have been observed feeding on crapemyrtle bark scale. Avoiding broad-spectrum or systemic pesticide use will help to conserve the beneficial natural predators in our environment and allow them to do their work on keeping this pest under control.
