Tree Insect Control

Leading Innovator in Tree Insect Control

Ross Tree Company prides itself on being a leading innovator in tree insect control. We were the first tree service company in Denver to offer tree injections, a practicable alternative to spraying trees. Trunk injections ensure that only the tree gets the product, not the surrounding environment. No need to close windows, cover furniture, or keep pets indoors when injecting trees to control tree pests. Trunk injections protect your trees for one or two growing seasons, depending on the application. Please see our insect calendar to find out more information about local harmful tree insects and diseases.

In contrast, spraying trees treats insects or diseases present at the time of treatment. Sometimes spraying is warranted because of an insect infestation or disease outbreak that needs immediate attention. Ross Tree sits down with the residential or commercial property owner to discuss all options before treatment commences.

Environmentally Friendly Insect Control

Ross Tree’s motto is “Integrity in Action,” which means we’re committed to minimizing our impact on the environment when delivering plant health care services. We deliver on this promise because our staff possesses the proper training and credentials to treat trees properly in the Denver area. Ross Tree has three Qualified Supervisors (QS) licensed by the Colorado Department of Agriculture to handle pesticide products. We only use the products necessary to treat your trees and nothing more. 

Trunk injections treat your trees for various tree insects such as Aphids, Emerald and Lilac Ash Borers, Mountain Pine, and IPS Engraver Beetles. We also inject nutrients and antibiotics to correct deficiencies or control tree diseases. Some tree insects are beneficial or benign. These bugs are part of the urban forest, so Ross Tree takes the time to identify if a tree insect is a friend or foe before treatment commences. Sometimes even with the best efforts, tree insects or diseases kill a tree, so, unfortunately, tree removal is necessary.  

Emerald Ash Borer Treatments

The Emerald Ash Borer (EAB) is getting closer to Denver after being found in Bloomfield and Westminster in 2019 and appearing in Arvada in 2020. American Ash trees have no immunity to the EAB and will die if not treated. So, prevention is a must to protect high-value, mature Ash against the EAB. Ross Tree uses tree injections to control these tree insects. We are a licensed Colorado Department of Agriculture Commercial Pesticide Applicator and offer several effective treatment options for controlling EAB. We recommend protecting trees for up to two years and are up to 95% effective against the EAB. Click here our handbook on Emerald Ash Borer.

Thanks for being so accommodating, crew did a great job as usual.
