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 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. Please see our insect calendar to find out more information about local harmful tree insects and diseases.
Sometimes spraying is warranted because of an insect infestation that needs immediate attention. Ross Tree sits down with the residential or commercial property owner to discuss all options before treatment commences.

What Are Systemic Tree Injections?
Trunk injections treat your trees for various tree insects found in the Denver area, including 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. Ross Tree uses systemics products to treat the following tree insects:
Emerald Ash Borer (EAB)
The EAB is here to stay. Since the beetle is moving up and down the Front Range, it is just a matter of time before it arrives in Denver. American Ash trees have zero immunity to the EAB and will die if not treated. So, prevention is the best tactic to save high-value Ash trees against the EAB. EAB control products are also effective against the Peachtree, Lilac, Ash Borers, and the Zimmerman Pine Moth. Click here for our handbook on the Emerald Ash Borer.
Elm Leaf Pests
Elms need some extra help in Denver since they are not native trees. Wet springs support large infestations of the Elm Leaf Beetle. We use systemics products to control the Elm Leaf Beetle and the Elm Leaf Miner, European Elm Flea Weevil, and Japanese Beetles. Click here to link to our handbook on Elm Leaf Pests.
Soft Body Tree Pests
Tree aphids and scales become serious tree pests when Denver has a wet spring. Many of these pests are tree species-specific. Applying dormant oils in the winter or systemic injections in the early spring controls many scale insects found in the Denver area. On the other hand, hot summers support the growth of the Honeylocust Spider Mite. Systemics are effective against this mite. Click here for more information on Spider Mite control.
