The invasive box tree moth, a highly destructive pest to boxwood shrubs, has been discovered for the first time in Pennsylvania, found in two cemeteries in Erie County. In response, the Pennsylvania Department of Agriculture has issued a quarantine to prevent the insect from spreading further. The box tree moth, already identified in other states like New York and Ohio, primarily spreads through the shipment of infected boxwoods.
The moth poses a significant threat to boxwoods, which are commonly used in topiaries and hedges, particularly in Pennsylvania’s renowned public gardens, parks, and conservatories. While the insect does not harm humans or food supplies, it jeopardizes the state’s nursery and landscaping industry, which generates $4.1 billion annually and supports more than 63,000 jobs.
Agriculture Secretary Russell Redding emphasized the economic importance of controlling the box tree moth, noting the risks to Pennsylvania’s tourism and horticulture industries. Businesses in Erie County are now required to keep boxwoods within the county unless they have a compliance agreement with the Department of Agriculture.
Homeowners and businesses are encouraged to report any suspected infestations and follow guidelines for identifying and controlling the pest. Early detection is critical to limiting the damage caused by the box tree moth. For more information and to report sightings, visit agriculture.pa.gov or contact badbug@pa.gov.
