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 South Dakota Department of Agriculture (SDDA) has confirmed that an infestation of emerald ash borer (EAB) has been discovered in northern Sioux Falls. This is the first confirmed infestation in South Dakota. Emerald ash borer is an invasive insect that has killed tens of millions of ash trees in at least 32 states. On May 9, 2018, Secretary Mike Jaspers implemented an Emergency Plant Pest Quarantine in order to prevent or reduce the spread of the EAB. This emergency quarantine is effective immediately. For more information, see the Emerald Ash Borer in South Dakota website.

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.
