Much like your primary care physician knows the intricacies of the human body, we specialize in understanding trees. We can spot problems like insect infestations and disease before it’s too late to stop them. We are not in the business of selling unnecessary annual service programs. DLC Arbor diagnoses the condition of your trees and prescribes the proper treatment to address it. Whether your tree requires a foliar spray, micro trunk injection or soil application, DLC licensed insect experts diagnose and administer the proper treatment in the least invasive and safest manner possible.
Spraying for Mountain Pine and IPS beetles is not longer recommended. Why? The pine and spruce beetle epidemic has ended. The populations of both beetles have returned to their pre-outbreak population levels. Many tree care companies are still recommending this service. If you see a promotion to spray your pine and spruce trees, throw it away. It is a waste of money.
Insects are a natural and necessary part of our urban forest ecosystem. Most insects are harmless. That’s why insect identification is so important. The photo above is an ash tree with holes created by the ash/lilac borer, not the emerald ash borer. DLC’s Certified Arborist help property owners identify the type of insects they are dealing with and determine what, if any action is necessary. In some cases, no action is needed when the presence of the insect is beneficial or if it has caused minor damage, and then left the tree.

Each year new invasive tree insects and diseases arrive in Colorado. In 2014 the emerald ash borer (EAB) was detected in Boulder.
