GreenStripe identifies the problem first — then determines whether treatment is actually necessary.

What Are You Seeing?

The Damage Often Shows Up Before the Insect.

Insects don’t always make themselves obvious, but they often leave behind signs. Here are some common symptoms homeowners notice.

  • Shiny sticky honeydew residue and dark sooty film on a glossy shrub leaf

    Sticky Leaves or Black Residue

    Could indicate sap-feeding insects producing honeydew.

  • Small raised scale insects clustered along a woody shrub branch

    Small Bumps on Branches

    Potential scale activity.

  • Ornamental leaf with fine yellow stippling and bronzed discoloration

    Speckled or Bronzed Leaves

    Potential mite or lace bug feeding.

  • Green leaf with ragged holes chewed by feeding insects

    Holes & Chewed Leaves

    Potential leaf-feeding insects.

  • Brown cone-shaped bagworm bags hanging from evergreen arborvitae branches

    Bags Hanging From Branches

    Potential bagworms.

  • Bare dying branches on an ornamental tree showing dieback

    Sudden Branch Dieback

    Could warrant investigation for borers, insects, disease or environmental stress.

Common Tree & Shrub Insects in New Jersey

Know the Pests. Protect Your Plants.

Here are some of the most common tree and shrub insects we encounter in Northern New Jersey.

  • Scale insects clustered along a woody tree branch

    Scale Insects

    Small sap-feeding insects that can be easy to overlook until populations become noticeable.

  • Spider mites and fine webbing on an ornamental shrub leaf

    Mites

    Tiny pests that can cause stippling, discoloration and bronzing of foliage.

  • Green aphids clustered on a tender ornamental plant stem

    Aphids

    Sap-feeding insects that can cause curling, distorted growth and sticky residue.

  • Bagworm bags hanging from an evergreen branch

    Bagworms

    Bag-forming caterpillars that can feed heavily on many ornamental trees and shrubs.

  • Round borer exit hole in the bark of an ornamental tree trunk

    Borers

    Larvae that feed within stems, branches or trunks, which can lead to decline or dieback.

  • Green caterpillar chewing the edge of an ornamental shrub leaf

    Leaf-Feeding Insects

    Beetles, caterpillars and other pests that consume foliage.

Our Approach

Not Every Bug Needs a Pesticide.

Seeing an insect doesn’t automatically mean your landscape needs to be treated. We take a thoughtful, informed approach.

  1. 01

    Identify

    What insect are we actually dealing with?

  2. 02

    Evaluate

    Is it damaging the plant enough to warrant intervention?

  3. 03

    Time

    When is the pest most vulnerable to treatment?

  4. 04

    Treat

    Choose an appropriate treatment based on the pest and situation.

Lower-Impact Options

Where appropriate, we incorporate products such as neem oil, horticultural oils and other lower-impact approaches as part of our plant-health strategy.

Targeted Insect Control

When pest pressure requires it, we use professional insect-control products selected for the specific insect and situation.

Timing Matters

Insect Control Isn’t Just About What We Apply. It’s When.

Different insects become active at different times of the year, and some treatments work best against specific life stages.

  • Ornamental tree buds breaking open in early spring

    Early Spring

    Emerging pests

  • White flowering shrub blooms in late spring

    Late Spring

    Peak activity for many insects

  • Dense green ornamental shrub foliage in summer

    Summer

    Monitor and respond

  • Ornamental shrub leaves turning red and orange in fall

    Fall

    Prepare for winter and target overwintering pests

Beneficial Insects

Some Bugs Belong Here.

A healthy landscape includes beneficial insects like lady beetles, lacewings and pollinators. Our goal isn’t to create an insect-free property — it’s to keep the right balance for a healthy, resilient landscape.
