Spotted Lanternfly


We, the PA Spotted Lanternfly program team, are reaching out to you because your municipality and its businesses and residents may be affected by Spotted Lanternfly (SLF), an invasive insect which was introduced into Pennsylvania in 2014. This pest poses a significant threat to important agricultural commodities including grape, hardwood, fruit trees, landscape and nursery products that contribute billions of dollars annually to PA’s economy.


But SLF is not just a concern to agricultural and horticultural professionals – it also poses significant quality-of-life frustrations for all residents. The large populations and habits of SLF can force even the most ardent nature lovers to stay inside. When feeding, SLF excrete a sticky waste, coating everything below them. This waste encourages the growth of black-colored sooty mold on plant materials and hard surfaces like decks and furniture.


To protect the state’s economy and residential quality of life, the PA Department of Agriculture issued an Order of Quarantine and Treatment to stop the movement of SLF to new areas and to slow its spread within the quarantine area. What does that quarantine mean to you and your municipality?


  •          Residents need to know how to “Spot the pest, Destroy it, and Report it”.  Each household should complete a Compliance Checklist and carry it with them when traveling.

  •          Businesses and Organizations:  The Order requires all agricultural and non-agricultural businesses, agencies, and organizations whose operations require the movement of any regulated articles, such as products, vehicles or other conveyances, within or from the quarantine to obtain an SLF permit. Businesses located in SLF infested areas of other states must also have a permit if traveling or transporting goods into PA. The SLF permit course and the permit are free! Visit the PDA SLF Quarantine page and PDA SLF Permitting for more information and resources.

  •          All landowners are responsible for controlling Spotted Lanternfly on their own property, to the best of their ability. Spotted Lanternfly can be controlled with a combination of physical and chemical means.  Penn State Extension has developed information for property owners which can be found on their SLF website. Use of these management techniques is an important step to control of this invasive pest.

  •          Whether inside or outside the quarantine, everyone is encouraged to report sightings of SLF, using the online SLF reporting tool or by calling 1-888-4BAD-FLY (1-888-422-3359).


To protect neighbors, communities, the agriculture industry and Pennsylvania’s business vitality, everyone needs to be aware of the SLF threat and how to utilize best management practices in their daily activities to avoid spreading SLF. 

Help stop the spread of the Spotted Lanternfly by sharing information with your municipality’s residents and businesses.
