Suspected Emerald Ash Borer Infestations

Ash trees are the EAB's preferred host, but white fringe trees and other species of trees sometimes suffer with EAB infestations. EAB larvae feed off these trees and interfere with the tree’s ability to transport water and nutrients. Once an ash tree is infested with EAB beetles, it has a 99-percent chance of dying from the related damage within three to four years.

Definitely schedule a tree inspection (or perform one yourself) in early spring. Look for signs of adult borers emerging from ash trees starting around the middle of April. The adult EAB leaves a 1/8-inch wide, D-shaped hole in the bark of the tree as it exits.

Other signs of EAB infestation include:

EAB adults spend a good bit of time in the upper branches of trees, so you may not see too many of the small, slim beetles even when an infestation is great. However, there are a host of other green, shiny beetles and bugs that are not invasive and are native to Missouri. Most of the green bugs you see in the state don't kill Missouri trees.

Seek a professional opinion about any green beetles or bugs you find on your ash tree. Your tree care professional has the skills to diagnose an EAB infestation for you, and they can help you remove any dying or dead ash trees if your trees are affected.

Younger, healthy trees can sometimes be treated for EAB infestations. Older trees with more than 50-percent EAB-related damage should be felled by your tree service. Removing heavily infested trees helps stop the spread of EAB and protects people and the surrounding property from harm due to sick, falling ash trees.

There are several treatments available to manage EAB infestations. Some products are available to homeowners but should be handled extremely cautiously or not at all. DIY treatments for EAB are also not guaranteed to stop a serious infestation.

Tree care professionals have access to more advanced EAB treatments that homeowners aren't allowed to use for DIY treatments. The advanced products don't always work either, but the professionals will apply the products in a safe and scientific manner as they attempt to save your trees. Call your tree service to learn more about all of the options for managing your ash trees before, during, or after an EAB invasion on your property.
