Emerald Ash Borer

What You Need to Know about the Emerald Ash Borer.

The Emerald Ash Borer is a small insect that burrows deep inside ash trees to lay its eggs. When the larvae hatch, they then eat their way out as they develop into adults. They are bright green in color and roughly the size of a penny when they are full-grown. They were recently detected in Boulder County, and have caused severe devastation to many of the ash trees around the city and county of Boulder.

While all of us here at Lawn Doctor take this issue seriously, we want our customers to know that it has not yet arrived in the Fort Collins area.

Should I be worried?

The answer is yes and no. No, the Emerald Ash Borer has not yet arrived in Larimer County, and it could take years before it gets here. It is currently only in Boulder county and the surrounding area, and is predicted to head south toward Denver.

Yes, it is advantageous to show a little concern. This insect will probably show its nasty green head in our area at some point, so it is good to be aware of it. However, you do not need to treat your trees until the pests get within a 15-mile radius of your property. As of now, treatment is not recommended.

Do I need to treat my trees now?

No. Treating your trees now is not recommended. Some tree companies may try to upsell by convincing you to spray now, before it is necessary. According to CSU, spraying your trees at this time is simply not the best action. If this changes, you can count on us to keep you up to date. Despite the current advisory to hold off on treatment, there are many things you can do to ensure your trees are as healthy and prepared as possible when they Emerald Ash Borers do arrive.

Aren’t I Already Treating for Ash Borer?

Many Fort Collins residents are already treating their trees for the more common Lilac Ash Borer. This ash borer is yellow in color, and reproduces in the same manner as the Emerald Ash Borer. Unlike the Emerald Ash Borer, however, the Lilac Ash Borer is already in Fort Collins, and it feeds on a variety of different plants. We currently have control plans in effect for these insects for many of our customers, and you are probably treating for this pest. Lilac Ash Borer treatment is not the same though, so if signs of the Emerald Ash Borer do show up in your area, you will need to treat for it as well.

What Can I Do to Protect My Ash Trees?

A healthy tree is a resilient tree. The best thing you can do to protect the trees and shrubs on your property is to make sure they are healthy and thriving now, before a significant threat arrives. On a basic level, you will want to ensure that your trees have proper nutrition and hydration. We offer deep root feeding and watering plans, and these are a great addition to your spring maintenance routine.

Current infestations and diseases can also weaken your trees and make them more susceptible to the Emerald Ash Borer once it heads north. If your trees are not at their healthiest, our certified arborists can inspect, treat, and improve their condition. That way they will be as prepared as possible to fight off an attack from the Emerald Ash Borer.
