Emerald Ash Borer is a Threat to Kansas Ash Trees

Kansas Counties Quarantined for Emerald Ash Borer: Douglas, Jefferson, Johnson, Leavenworth, Wyandotte.

The emerald ash borer is a pest of ash trees native to Asia. It was first discovered in North America in 2002 in the Detroit, Michigan, area. Since then, it has killed millions of ash trees and caused thousands more to be removed to slow its spread.
Since its initial discovery, the core area affected by the beetle has expanded. It has been detected in Ohio (2003), Indiana (2004), Illinois, Maryland (2006), Pennsylvania, West Virginia (2007), Virginia, Wisconsin, Missouri (2008), Minnesota, Kentucky, New York (2009), Iowa, Tennessee (2010), Connecticut, Kansas, Massachusetts (2012), Georgia, New Hampshire, North Carolina, Colorado (2013), New Jersey, Arkansas (2014).

If you suspect emerald ash borer on your property, and are not in one of the quarantined counties, please call 7855646698 or email your name, address, phone number and pictures of the suspect tree to ppwc@kda.ks.gov.

All ash trees native to Kansas are susceptible to infestation by the emerald ash borer. Trees become infested when adult beetles lay eggs on the bark. The eggs hatch into larvae that bore into the tree. They tunnel between the bark and wood and disrupt water and nutrient movement, eventually killing the tree. Emerald ash borer appears to prefer trees under stress, but is capable of killing perfectly healthy trees.

Emerald ash borer is responsible for killing or damaging 20 million ash trees in Michigan, Indiana, Ohio and Ontario, Canada. Financially, the United States risks an economic loss of $20 billion to $60 billion because of this pest. A complete devastation of ash trees could seriously affect our ecosystem. Without government action and cooperation from the public, firewood dealers, arborists and the nursery industry, emerald ash borer will be introduced in Kansas.

Preventing its introduction is far more cost effective than trying to contain it as an established pest.
