The spotted lanternfly is an invasive insect from Asia currently found in southeastern Pennsylvania, and sightings have been reported in some neighboring states.
The pest threatens important agricultural commodities, including the grape, hardwood, tree fruit, landscape and nursery industries - sectors that contribute nearly $18 billion annually to Pennsylvania's economy.
This planthopper weakens plants by feeding on sap. It excretes a sticky, sugary substance called honeydew, which attracts stinging insects, promotes the growth of sooty mold and causes a messy nuisance for residents.
To help stop the spread of spotted lanternfly, the state has issued a quarantine order requiring the inspection of all items moving within or out of the area to prevent the transport of any living life state of the pest.
Report a Sighting:
- Check if you're in or out of the quarantine zone by visiting extension.psu.edu/spotted-lanternfly.
- Kill and collect the specimen by freezing it or placing it in rubbing alcohol. If you are able, take a picture of it.
- Report the sighting online at extension.psu.edu/spotted-lanternfly. If you cannot access the internet, please call 888-4-BADFLY (888-422-3359) toll-free. Please only use this hotline for sightings outside the quarantine zone.
Stop the Spread:
- Destroy all life stages of the spotted lanternfly that you find.
- Check your car and outdoor equipment for spotted lanternfly eggs, nymphs and adults before moving within or out of the quarantine zone. Don't move firewood.
- Share your spotted lanternfly knowledge with others!
