We rarely spray, but when the tent caterpillars are this bad, we trust you to do it correctly. Our arborist took the time to fully explain what the spray was and how it would affect insects, plants and songbirds. Please thank him for a job well done!

Davey trimmed our hillside today. They climbed and worked tirelessly while being receptive and reactive to our requests. The trees needed major trimming, but also appealing pruning, and they accomplished this with care. Looking forward to recommending Davey & using them again in years to come.

Tree Care Services

Tree Insect and Disease Management

There are a number of tree pests and diseases typically found in the Pacific Northwest. Since our local arborists are familiar with the environment, diagnosing and recommending a plan for treatment is a common service we perform. Some of the area pests and diseases include:

Cherry Bark Tortrix - Common in western Washington, all woody shrubs or trees in the rose family are susceptible to this pest. Infestation signs include reddish-orange “frass tubes,” oftentimes along with a gum-like resin protruding from the bark.

Dogwood Anthracnose - Spotting and blotching of leaves characterize this disease commonly found in dogwood trees. Trees that are stressed out from drought, winter injury or construction damage are more susceptible. Learn about early detection tips here

Scale Insects - These insects are common on a variety of woody plants, trees and shrubs. Large numbers can damage the host tree by sucking juices from the vascular system. See what scale insects look like here.

Learn how to effectively manage the pests or diseases you’ve come across. Contact your Seattle arborist for a treatment plan.

Other Tree Services in Northwest, Seattle

  • Cabling & Bracing

    Our certified arborist effectively pinpoint weak limbs that need cables and braces to reduce potential risk. Professional installation strengthens weak branches and reduces tree stress caused by weather elements and heavy foliage.

  • Tree Risk Assessment

    Schedule seasonal tree risk assessments to keep your trees and home safe. Certified arborists can identify safety hazards and potential weaknesses earlier. Catching problems early is far cheaper and safer than treating advanced problems later.

  • Shrub Pruning

    Have a Davey arborist prune your shrubs to keep them shapely while also allowing more light onto the shrub. The result? Healthy shrubs with denser foliage that look better than ever.

  • Air Spade

    Many tree problems start at the roots, and left untreated, can lead to tree failure. Certified arborists use air spades to diagnose root problems and remedy root flares. This tool reduces soil compaction while safely unveiling tree roots for arborists’ inspection.
