Emerald Ash Borer Treatment
It’s time to start Emerald Ash Borer (EAB) treatment, now! This green jewel beetle is getting closer to Denver after being found in Bloomfield and Westminster in 2019. Arvada confirmed its presence within its city limits in 2020. City forest services across the Denver area expect residential and commercial property owners to manage their trees for EAB properly. So, it is time to treat mature Ash trees.
We are not being pushy, but mature Ash trees are valuable and need proper Emerald Ash Borer treatment since these trees have zero immunity against this borer. Ash tree management is treating mature trees and removing any marginal trees from yards. (A questionable Ash tree is one in poor health or growing under a power line.) Ross Tree is a licensed Colorado Department of Agriculture Commercial Pesticide Applicator for Emerald Ash Borer treatment. We offer several effective EAB treatment options for controlling this beetle and its larvae. We are committed to only using what is necessary to treat the trees of our customers and nothing more. Check out Ross Tree’s EAB Handbook for the latest news on EAB in the Denver Area.
EAB Treatment Options
For young Ash trees, we use a systemic bark spray. A Ross Tree plant care specialist sprays the trunk up to five feet above the ground. Young trees absorb the product for protection against these borers. We prescribe trunk injections for larger trees and administer the EAB control products directly into the tree. The tree’s vascular system distributes it throughout the tree. The insects’ larvae or adults die when they chew on the tree’s nutrient-conducting tissues or leaves, respectively. Trunk injections are cost-effective because they last two years and are environmentally friendly.

What does the EAB do?
Kills ash trees!
Larvae feed under the bark, eventually girdling the tree and cutting off nutrients.
Trees are killed within 2-4 years of first symptoms, even previously health trees.
Trees of all sizes can be attacked, from 1/2-inch saplings to the largest mature trees.
This insect is very difficult to detect because it is under the bark and the adults are only around from May to September.
The best time to treat Ash trees is in June and July.
Ash Tree Management
Residential and commercial property owners with Ash trees need to ask themselves how much they value them since tree value comes from the following:
A mature tree landscape adds between 5 to 10 percent to a property’s value. Denver’s real estate market has shot up substantially since the 1990s, so the worth of mature trees in a yard equates the cost of a new automobile.
If their trees are lost, most homeowners will miss the beauty of their trees, but also their shade when the hot, western sun bears down on their homes.
Ash Borer treatment is less expensive than removal. To remove a large tree, Ross Tree may need to use a crane and pull a street closing permit, which dramatically increases removal costs.
There are about 1.5 million Ash trees in the Denver area. Once the EAB makes its presence known in Denver, it might be close to impossible to book an appointment with a tree service company. It is best to take the initiative and treat your Ash trees now by calling Ross Tree.
