About the Spotted Lanternfly

The Spotted Lanternfly (SLF) is a relatively new pest in southeast Pennsylvania.  It can damage many plants including fruit and hardwood trees and grapes.  SLF can also cause serious damage to yards, open spaces, plant nurseries, tree farms, and vineyards.  If we do not control its spread, other states or countries could restrict the transport of PA products.
