Did you know that in Colorado, the predominant tree species is the ash tree? In fact, 20% of Grand Junction's tree population are ash trees! Unfortunately, these trees are frequently plagued by insect infestations that can severely damage them. The most prevalent pests are bark beetles and lilac ash borers. Fortunately, there are specific treatments available to address these infestations. For instance, bark drenches and trunk injections have proven effective in combatting these pests. In addition, certain treatments for lilac ash borers can offer long-lasting protection even after the initial application.


Bark drenches and trunk injections are treatments used to combat ash tree insect infestations.

Different types of treatments are available for ash trees in Grand Junction, CO, depending on their condition. Bark drenches are one treatment method used to combat insect infestations on ash trees. This treatment involves the application of a specialized solution to the trunk of the tree. The solution acts as a soak, penetrating the tree bark surface. Once applied, the solution is absorbed by the tree, effectively targeting and eliminating pests around the affected area.

Another type of ash tree treatment is trunk injections. Trunk injections are an effective method of delivering insecticide directly into the vascular system of an ash tree. This involves inserting a needle into the tree and injecting the insecticide, which is then dispersed throughout the tree, targeting the pests. By utilizing the tree's natural transport system, trunk injections ensure that the insecticide reaches different parts of the tree, providing a thorough and targeted approach to combating infestations.


Ash trees are often affected by bark beetles and lilac ash borers.

Bark beetles and lilac ash borers are common insects known to detrimentally affect ash trees in Grand Junction, CO. Bark beetles are small, cylindrical insects that bore through the bark of ash trees to lay their eggs. Once the eggs hatch, the beetle larvae feed on the tree's inner bark, disrupting the tree's nutrient transport system and causing significant damage.

On the other hand, lilac ash borers are a species of moth known for their destructive feeding habits. They lay their eggs on the bark of ash trees, and once hatched, the larvae tunnel into the tree, disrupting its vascular system and weakening its overall structure. If left untreated, these infestations can lead to dieback and structural damage.


Some ash tree treatments not only stop pests but also protect against them!

Some treatments for lilac ash borers offer more than just pest elimination. They can provide long-lasting protection even after the initial application. By forming a barrier within the tree, these treatments not only target existing infestations but also help prevent future attacks, offering extended protection for the health and vitality of ash trees. This sustained defense can last for multiple years, ensuring ongoing resilience against lilac ash borer infestations.

There are multiple varieties of ash trees in Grand Junction, CO, including green ash and white ash.
