Delaware Department of Agriculture.
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.

Firewood is widely recognized as a major source of non-native forest insect and disease infestations. A rule governing the importation of untreated firewood into Vermont went into effect on May 1, 2016. Visitors to Vermont State Parks, Vermont State Forests, and the Green Mountain National Forest may only bring firewood originating from Vermont or that is heat treated and in its original, labeled package. To help slow the spread of emerald ash borer within Vermont, ash firewood that has not been heat treated should not be moved outside of the Emerald Ash Borer Infested Area in Vermont.

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.
