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.

If you plan to use your own boat or angler float tube, you’ll need a permit and a free Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.

With the quarantine of ash trees in Arkansas, the threat of the Emerald Ash Borer (EAB) to millions of Oklahoma ash trees intensifies for southeastern Oklahoma, especially McCurtain and Le Flore counties. As the pest is literally next door, Oklahoma Forestry Services is asking Oklahomans to help prevent the infestation spread and be on the lookout and report any signs that the insect is in the state. Please notify Oklahoma Forestry Services at 405-522-6158 if you see signs of EAB infestation in ash trees. For more information about the Emerald Ash Borer visit www.forestry.ok.gov/tree-pest-alerts.

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.
