Inspect Your Trees Since the Adult Emerald Ash Borer Emerges in Spring

Posted on April 6, 2020

The adult emerald ash borer (EAB) has been a significant and destructive pest in Pennsylvania for years. First discovered in the United States in 2002, the emerald ash borer has caused considerable damage to ash trees across the United States, affecting both the environment and the economy. Because spring is when these adult beetles emerge and begin devouring the canopy of ash trees, we advise all residents to prepare and protect ash trees from this pest.

What Can You Do to Protect Your Trees from Adult Emerald Ash Borer?

Stein Tree Service recommends a few things that could help you protect your trees.

Inspect Your Trees Regularly

The adult emerald ash borer emerges in spring, but you should be on the lookout for them all year, as larvae activity damage can be seen when the trees are bare in winter.

Signs of Emerald Ash Borer Activity

Generally, the first major sign that EAB has infested a tree is a thinning of leaves at the top of the tree. Unfortunately if you see this symptom, your tree has likely been under attack for some time already. Other signs to look for include the following:

  • Yellowing of leaves
  • Epicormic shoots
  • D-shaped exit holes
  • S-shaped galleries under the bark
  • Unusual woodpecker activity

How to Help Protect Trees from Adult Emerald Ash Borer

Other ways to help protect ash trees from EAB include buying and burning only local firewood. Eggs and larvae can be carried on firewood, so keeping to this rule helps prevent the spread of EAB into uninfested areas. Educating others about emerald ash borer signs is another way to proactively protect the trees in your community.
