Why should I be concerned about EAB?
The emerald ash borer is an invasive pest from Asia that kills untreated ash trees in Colorado fairly quickly (within 3-5 years). Additionally, infected trees become a hazard for neighboring uninfected and untreated ash trees, thus amplifying the problem. Your untreated trees provide a host for the emerald ash borer to kill your tree, then multiply and spread throughout the neighborhood. The emerald ash borer has been in the United States since 2002, and it has already killed tens of millions of ash trees.

What type of trees does EAB attack?
The EAB will eventually kill all untreated ash trees in Colorado and across the United States.

How do I know if I have EAB in my trees?
A telltale sign of an EAB infestation is that large portions of your tree canopy are leafless, with additional rapid dense sucker growth near the base or middle of the tree. Also, if there are 1/8th inch size D-shaped exit holes in the bark, or increased woodpecker activity around the tree, you probably have an EAB infestation. Some of the signs of emerald ash borer can be quite similar to other types of insects and weather damage. Fortunately, the treatment for emerald ash borer also prevents other types of insect damage. Unfortunately there is no treatment for weather-related damage, i.e. early or late freezes.

How long does it take for EAB to kill a tree?
Three to five years for untreated trees. However, very obvious signs of emerald ash borer infection generally don’t show up until about 3 years after the initial infection, and by then it is sadly too late to save the tree.

When did the EAB problem start in Colorado?
The EAB invasion first arrived in Boulder in 2013, and had become widespread in Denver by 2018.

Does the EAB go away on its own?
Unfortunately, no. The EAB will kill your tree, then move on to the next available untreated ash tree in the neighborhood.

Can my ash tree survive an emerald ash borer attack without being treated with Emamectin Benzoate?
Unfortunately, no. All ash trees in the Denver area will ultimately require treatment to survive. The EAB invasion is indeed that bad.
