Sandy, Oregon Tree Care & Emerald Ash Borer

The emerald ash borer, also known as EAB, is a significant problem throughout the U.S, and it’s essential for residents to be aware of this infestation to protect their trees. To keep our clients and community informed, the certified arborist at Westcoast Tree Care would like to provide you with the following answers concerning emerald ash borer and Sandy, Oregon tree care.

Does EAB Kill Trees?

Yes. Adult EAB beetles lay eggs within the bark of an ash tree, which hatches approximately two weeks later. Once hatched, the EAB larvae will feed on the bark, eating the inner tissues of a tree. These layers feeding the EAB larvae are responsible for transporting nutrients and water throughout a tree. How long it takes for an infected tree to die depends on its size and maturity and the size of the infestation. Generally speaking, EAB infested trees often die within 1-4 years.

Will My Ash Trees Get Emerald Ash Borer?

It’s possible. Most ash trees are at risk of emerald ash borer as the infestation continues to spread across the U.S. However, it’s important to note that the American mountain-ash is a species of tree that has yet to be affected as it’s not considered a true ash tree. Keep in mind that EAB prefers stressed or diseased ash trees but can attack healthy trees as well.

Do I Need To Worry About My Other Trees?

Probably not. EAB tends to only infect and feed off ash trees. As reported in the U.S, EAB is only damaging ash trees.

How Is EAB Detected?

The signs of an EAB infestation can take quite a while before becoming visible. However, you can still spot EAB with a little diligence. Below are a few main things to look out for:

Upper canopy die-off.
Epicormic branching, which looks like small tufted shoots on the trunk of a tree.
Distinctive D-shaped holes left by hatched larvae.
Vertical splits in the bark.
Excessive damage from woodpeckers eating larvae

How Can I Get Rid of EAB?

The best way to get rid of EAB and prevent it from spreading to nearby, healthy trees is to stay on the lookout for any of the above-mentioned signs. If you spot any of these issues, it’s important to contact the certified arborist at Westcoast Tree Care to take care of the problem.
