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.
Your local Davey arborists are also your neighbors. Because of this, they have the knowledge of Seattle, Washington and its surrounding suburbs, and know what’s needed to make your property flourish. They have a passion for tree care and it shows in the work they perform in your yard.
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.
Sometimes, it takes additional research to diagnose a tree disease or problem our Northwest Seattle, Washington arborists come across. That’s when the scientists and technical advisors at The Davey Institute step in. With the ability to collect tree and plant samples and send them back to the professionals in our diagnostics lab, no tree or plant disease is too complex for Davey.

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.
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.
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.
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.
