Flies on bush/leaves

Asked August 1, 2018, 11:40 AM EDT

We've noticed this on one of our bushes/tree. The leaves appear very shiny and sticky looking. We've noticed hundreds of flies on the leaves and the tops of the leaves have white spots on them and the underside has what appears to be very small 'baby' flies that are stuck to the leaves. Trying to figure out what is happening and how to treat.

These look like winged aphids on a crape myrtle. Aphids feed on plant sap and secrete a sticky substance called honeydew. The honeydew is attractive to flies and other insects as a food source. Aphid populations can be reduced by washing the branches with a strong spray of water from a garden hose. In addition, natural predators (beneficial insects) typically catch up to aphids and help to control their populations naturally. On our website, you can read about other aphid management options, including biological control.
