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.

Residents are calling the Township office, asking if there is anything Concord Township can do to get rid of these invasive insects. Unfortunately, Concord Township does not have a license to spray pesticides. Visit these resources for more information and to find ways to combat these pests:

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.

The Department of Agriculture is calling on people in quarantined areas to inspect themselves and their vehicles before moving around, since spotted lanterflies are hitchhikers.

Residents with backyard infestations can purchase or make their own tree traps, remove plants that attract the insects, and use insecticides. You also can report spotted lanternfly sightings online or by calling 1-888-4BADFLY (1-888-422-3359).
