The emerald ash borer certainly has the attention of Colorado residents and for good reason. Nearly 15 percent of the trees that make up the state’s urban forest are ash. Can you imagine such a large chunk of our beautiful landscape being wiped away by a beetle? Unfortunately, that’s a real possibility. When it comes to EAB, we have decisions to make. For example, if your tree were to be impacted by the disease, would it be worth saving? At what point should you consult a certified arborist? In this blog post, we will explain how to properly manage this insect.

Colorado State University and the Colorado Department of Agriculture recently put together a guide illustrating important decisions homeowners will have to make when it comes to EAB. Let’s go through a few of the more common scenarios should you choose to save your tree.

Keep in mind that not every tree is worth saving. If you’re looking to save money, it’s best to have unwanted ash trees removed before they die. However, if there are just a few signs of EAB, you have a big choice to make. First, determine the size of your trees. Do this by measuring the distance around the trunk and divide it by three to get the diameter at breast height. If the diameter is greater than 15 inches, the tree will require insecticide treatment from a professional tree service. By no means should you take this level of tree care into your own hands. Be sure to get multiple estimates, ask for references/insurance, and only hire someone who is certified.     

Now let’s say that the diameter of your tree is less than the aforementioned 15 inches. In this case, homeowners can handle the situation on their own. Consider using a soil drench that contains a substance called imidacloprid. This insecticide essentially acts as a neurotoxin. Treat your tree between May 1st and June 15th. As with all tree care products, follow label directions to a tee unless told otherwise by a professional.

How to Tell if Your Tree Can Be Saved From EAB

Trees can be saved from an infestation if they are:

  • Healthy and growing vigorously, with more than half their leaves
  • Either enhancing the landscape or valuable to the owner
  • Showing only a few outward signs of infestation

It would be wise to not save trees that are infested if they are:

  • Unhealthy, with dead branches and at least half of their leave missing
  • Planted in poor sites or are no longer important to the landscape
  • Showing a number of outward signs of EAB infestation such as woodpecker damage, bark splits, and water sprouts at the base
