Tree Pest & Disease Control in Aurora, CO

Colorado-licensed diagnosis and treatment for tree pests, fungal disease, and plant health threats — before they cost you a tree.

Colorado's Most Destructive Tree Threats

Colorado's Front Range trees face increasing pressure from invasive pests and stress-related diseases. Early identification and treatment is the difference between saving a tree and losing it. Our team is Colorado Department of Agriculture certified — meaning we're licensed to diagnose and apply pesticide treatments that unlicensed operators cannot legally use.

Emerald Ash Borer (EAB)

The most devastating pest to hit Colorado's urban forest. EAB has killed millions of ash trees nationally and is spreading through Aurora and Denver. Ash trees that are not treated will die. Treatment with trunk injections (emamectin benzoate) is highly effective when started before the tree is more than 40% declined. If you have ash trees, call us now.

Oystershell Scale & Lecanium Scale

Hard to see until damage is severe. Scale insects suck plant sap and produce honeydew that causes sooty mold. We treat with dormant oil applications and systemic insecticide programs.

Aphids & Spider Mites

Common on ornamental trees and shrubs — typically managed with targeted sprays timed to pest lifecycle. We identify the specific species before treating to select the most effective and least disruptive approach.

Cytospora Canker & Other Fungal Disease

Common in stressed Colorado trees, particularly spruce. Cankers girdle branches and move down the trunk. Proper pruning, fungicide application, and stress reduction are the treatment protocol.

Iron Chlorosis

Aurora and Denver's alkaline soils frequently cause iron deficiency — visible as yellowing leaves with green veins. Treated with soil acidification and chelated iron injection.

Certified Spray Supervisor on staff. Derek Stroden holds a Colorado Department of Agriculture Certified Spray Supervisor license — a credential required for legal pesticide application in Colorado. We treat what others can't.
