A destructive, invasive beetle that kills ash trees, the emerald ash borer (EAB), has been confirmed in Delaware, making it the 28th state to have found the insect, the Delaware Department of Agriculture announced today. Delaware will be added to a federal quarantine already in 27 other states restricting the interstate shipment of all ash wood and wood products - ash nursery stock, green lumber, waste, compost and chips - as well as hardwood firewood of all species.

The Delaware Department of Agriculture (DDA) announced today that they expanded the spotted lanternfly quarantine to include all portions of New Castle County north of the Chesapeake and Delaware Canal. This is due to recent detections of established populations outside of the initial quarantine zone enacted in February 2019 that included eleven zip codes. "This expansion is necessary in our attempt to eradicate, control, and prevent the spread of spotted lanternfly in Delaware and to surrounding states," said Secretary of Agriculture Michael T. Scuse. The spotted lanternfly is a destructive invasive plant hopper that attacks many hosts including trees, shrubs, orchards, grapes, and hops. For more detailed information regarding the quarantine, permitting, treatment, or to report a sighting of spotted lanternfly, visit the Delaware Department of Agriculture’s dedicated spotted lanternfly webpage at https://de.gov/hitchhikerbug or call the dedicated spotted lanternfly hotline at (302) 698-4632.

Emerald ash borer (EAB), a destructive insect from Asia that attacks and kills ash trees, has been confirmed at two new sites in Delaware: one near Middletown, New Castle County, and another near Seaford, Sussex County. Originally found in northern Delaware in 2016, the new detections create added urgency for homeowners and municipalities to determine if they have ash trees on their property and decide on possible management options. Current guidelines recommend the removal or treatment of ash trees if located within 15 miles of a known infestation. Because Delaware is geographically small and EAB can go undetected for years, residents are urged to educate themselves now and take action.
