Spotted Lanternfly

Picture of the life cycle of the Spotted Lanternfly.

The Spotted Lanternfly (SLF) is a destructive invasive pest, that does not bite or sting but is threatening agricultural, timber, and ornamental industries, and the plants in your backyard. Together, we can take action to limit the spread and damage from this pest.

Helpful tips for homeowners to limit the spread and damage of the SLF include:

  • If you find a spotted lanternfly outside the quar­antine zone, collect and report it immediately with the online reporting system at extension.psu.edu/spotted-lanternfly or by calling 1-888-4BAD-FLY. SLF found within the quarantine zone do not need to be reported.
  • Don’t let SLF spread. Check your car, outdoor equipment, etc., for SLF eggs, nymphs, and adults when moving in and out of the quarantine zone. Don’t move firewood.
  • Help reduce SLF populations by scraping egg masses from trees, houses, and anywhere else you find them. Destroy mobile stages of SLF by crushing them.
  • Band trees to trap and kill nymphs in the early spring.
  • Remove tree-of-heaven, the preferred host for SLF.
  • If needed, protect your trees by applying insecticides using foliar or soil drench methods or consult a local tree care service. Always follow label instructions when apply­ing any pesticide.
