Emerald Ash Borer (EAB): A Guide to Early Detection
The Emerald Ash Borer (EAB) is a harmful and invasive pest that can cause significant damage to ash trees throughout Colorado. As an ash tree owner, you must recognize the early signs of an EAB infestation to protect your landscape and mitigate potential damage. Here are some helpful tips for identifying an infestation before it becomes a serious issue.
Understanding the Emerald Ash Borer (EAB)
The Emerald Ash Borer is a small, metallic green beetle native to Asia. Adult beetles measure approximately half an inch long and typically emerge in late spring. Their larvae are particularly destructive, feeding beneath the bark of ash trees and disrupting the flow of nutrients and water within the tree.
Familiarizing Yourself with Symptoms
- Canopy Decline: One of the first signs of an EAB infestation is a noticeable decline in the tree's canopy. Look for thinning leaves at the top of the tree, yellowing foliage, and wilting leaves. If your ash tree appears unhealthy and is losing vitality, it may indicate an early infestation.
- D-shaped Exit Holes: When adult EABs emerge, they leave behind distinctive D-shaped exit holes in the bark, which measure about 1/8 inch wide. The presence of these holes is a strong indicator of an Emerald Ash Borer (EAB) infestation.
- S-shaped Galleries: Beneath the bark, EAB larvae create S-shaped galleries as they feed. If you peel away some bark from your ash tree, look for these light brown tunnels, which are signs of infestation.
Keep an eye out for Bark and Wood Decay.
Infested trees may exhibit cracks in the bark or significant wood decay. Look for loose bark or wood that appears to be crumbling, as this can indicate that the inner layers of the tree have been compromised due to Emerald Ash Borer (EAB) activity.
Are you seeing any Woodpecker Activity?
Woodpeckers are natural predators of EAB larvae. An increase in woodpecker activity on your ash tree may indicate an underlying infestation. Woodpeckers often peck at the bark to access the larvae, leaving noticeable holes in the bark.
Visually Inspecting Trees
Regularly inspect your ash trees, especially during the spring and summer months when emerald ash borer (EAB) activity is at its peak. Please take a moment to walk around the tree and examine it from different angles. Pay close attention to the bark, branches, and overall health of the tree.
