Tree Pest and Disease Control

If you think a tree pest or disease may be present in your neighborhood, it is important to start thinking about your prevention and treatment options. Below, we’ve included a list of some common diseases that affect Long Island trees and the symptoms to watch out for:

  • Hemlock wooly adelgid: Wool-like wax that appears on eastern and Carolina hemlock trees resulting from a small, aphid-like insect
  • Gypsy moth: Moth larvae covered in spines and blue and red dots that slowly eat away at tree and shrub foliage
  • Bagworms: Destructive insects that create bags around themselves and feed on deciduous and evergreen tree foliage
  • Scales: Highly modified insects that cause black, sooty mold to appear on the surface of trees

Davey Tree offers prevention and treatment options for these common issues and more. If you are concerned one of your trees may be suffering from a disease or pest infestation, find your local Davey arborist for expert advice and a diagnosis. 

The Davey Institute

We believe tree care is a science. That’s why each arborist at our Long Island office is trained at The Davey Institute, a cutting-edge research facility advancing the industry with leading tree and lawn care research.

For one month each year, The Davey Institute of Tree Sciences (DITS) brings employees from all over the country together for a highly intensive training course. Throughout this training, our arborists learn new and innovative ways to diagnose common tree issues and gain experience in horticulture, plant pathology and more.

All Long Island Tree Services

  • Tree Removal

    Damage, disease or safety concerns can turn some trees from an asset into a liability. When this occurs, Davey’s certified arborists can be trusted for safe and efficient tree removal.

  • Tree Pruning

    Tree pruning is an important tool to help sustain a tree’s health and retain its natural appearance. Davey assesses your tree’s pruning needs from removal of unhealthy limbs to disease reduction.

  • Tree Planting

    Planting a tree that will thrive depends on the landscape, the climate and property goals. Our certified arborists provide expertise on “right tree, right place” – what trees to plant and where and how to plant them.

  • Lawn Care Services

    Davey professionals recognize that lawns need healthy roots for healthy growth. We provide a variety of services and an exclusive formula of nutrients to meet your lawn’s specific needs and help your turf thrive.

  • 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.

  • Landscape Management

    Our team provides a full-range of landscape maintenance services to manage the health and aesthetic appearance of your property.

  • 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.

  • 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.
