Spotted lanternfly (SLF) is more than a nuisance, it poses a serious risk to vineyards. Brian Walsh, Extension Educator and Spotted Lanternfly Researcher with Penn State Extension, explains how this invasive insect threatens grapes across the eastern U.S. From unusual egg-laying behavior to honeydew-covered canopies that attract stinging insects, Walsh explores why vineyards are especially at risk and how growers can prepare during peak pressure in September. Learn about insecticide options, biocontrol efforts, and scouting strategies—whether SLF is in your area or not.
