The Growing Threat of Emerald Ash Borer in Our Northern Colorado Community
Emerald Ash Borer (EAB) is an invasive insect that has been devastating Ash tree populations
across the country, and unfortunately, it is now spreading rapidly through our community. If you
have Ash trees on your property, and you are not already treating your Ash trees, now is the
time to protect them before it’s too late.
The Spread of EAB in Our Area
In the past year, EAB detections have surged in multiple locations. EAB was first discovered in
north Fort Collins in 2020 and then again in 2021 in east Fort Collins, but last year (2024),
infestations were confirmed in several new areas, including Loveland, south Fort Collins, and
west Fort Collins. This rapid spread indicates that Ash trees throughout our area are now at a
much higher risk of infestation.
Take a look at the map below to see where EAB has been confirmed and how quickly it is
expanding. If your property is near one of these locations, your trees are at an even greater risk.
What Does EAB Do to Ash Trees?
Emerald Ash Borers are highly destructive beetles that lay eggs under the bark of Ash trees.
When the larvae hatch, they tunnel through the tree, cutting off its ability to transport water and
nutrients. This leads to branch dieback, canopy thinning, and ultimately, the death of the tree.
Without treatment, nearly all infested Ash trees will succumb to EAB within a few years.
How You Can Protect Your Ash Trees
The good news is that there are highly effective treatments available to protect Ash trees from
EAB. Preventative treatments can stop infestations before they start and save your trees from
decline. However, timing is crucial—once a tree is heavily infested, treatment is no longer an
option, and the tree will need to be removed.
If you have Ash trees on your property, we recommend scheduling an inspection as soon as
possible. Our team of Certified Arborists offer professional assessments and proven treatment
options to ensure your trees remain healthy and strong.
