Native to certain parts of Southeast Asia, the Spotted Lanternfly is a plant hopper, invasive insect that has spread throughout Pennsylvania since its discovery in Berks County in 2014. The Spotted Lanternfly feeds on the plant sap of many different plants, including important forestry and agricultural crops in PA. They can cause significant damage and should be destroyed if found.
The Penn State Extension website is an excellent source for Spotted Lanternfly information.

Spotted Lanternfly Quick Facts (from Penn State Extension):
- SLF is a destructive invasive pest threatening agricultural and ornamental plants.
- As of May 2020, 26 counties in Pennsylvania are under quarantine for SLF. SLF has also been found in 5 other states in the northeastern U.S.
- SLF does not bite or sting.
- SLF does not kill all trees it feeds on. SLF is a plant stressor that, along with other stressors, can cause significant damage to its host.
- Stop the spread of SLF by checking your car and any outdoor equipment (grills, mowers, firewood, etc.) when going in and out of the quarantine zone.
- Manage SLF on your property by scraping and destroying eggs, carefully using bands or traps on trees, removing preferred hosts, and using registered insecticides for control when appropriate.
