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.
Spring Egg Hatch 2020
An early spring means warmth, flowers, and eminent hatching of thousands of SLF egg masses. Most likely the hatch will begin in southern Pennsylvania in mid- to late-April and lag by a week or so in more northern counties. The majority of SLF hatch (more than 50%) will likely be in mid to late May.

Tips for Homeowners
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.
