Insect & Disease Management in Greenville

Clear Diagnosis & Targeted Care for Troubled Trees

Canopy decline, bark damage, unusual insect activity, and other changes can signal a serious tree health problem. Our insect and disease management service gives Greenville property owners a clear starting point: we inspect the affected tree, identify visible concerns, and recommend care based on what we find.

Monster Tree Service of Greenville County provides professional tree care for projects of any size. We arrive on time, explain our recommendations, and provide free, no-obligation estimates with upfront pricing.

Don’t wait for visible damage to spread through the canopy. Call (864) 756-5665 to request an inspection and discuss the next steps for your tree.

How We Identify Tree Insects & Diseases

Effective treatment starts with identifying what’s affecting the tree. Similar symptoms can have different causes, including fungal infection, invasive tree pests, nutrient deficiencies, drought, flooding, storm damage, or several tree stress factors occurring at once.

Our assessment and recommendation process may include:

Visual inspection: We examine the foliage, canopy, branches, trunk, bark, and surrounding site for signs of insects, disease, or environmental stress.
Problem identification: We evaluate the symptoms before recommending a custom plant health care plan for the issue found.
Treatment recommendations: Based on our findings, we may discuss targeted care, monitoring, pruning, or other appropriate measures.
Removal evaluation: If a severely affected tree can’t reasonably be preserved, we may recommend removal to reduce the risk to nearby healthy plants.

Not every insect on a tree is harmful. Many naturally occurring insects coexist with trees, while introduced or invasive species are more likely to cause serious damage. Careful identification distinguishes a harmful infestation from normal activity.

Invasive Tree Pests Affecting Greenville

Two invasive insects Greenville property owners should recognize are the emerald ash borer and spotted lanternfly.

Emerald Ash Borer

Emerald ash borer was officially detected in Greenville County in August 2017 and remains established in the area. Its larvae feed beneath the bark of ash trees, disrupting the movement of water and nutrients and potentially causing rapid, fatal decline.

Possible emerald ash borer warning signs include:

Thinning or yellowing in the upper canopy
New shoots growing from the trunk or base
Vertical bark splits
Small D-shaped exit holes in the bark

Preventive insecticide treatment may help protect a high-value ash tree when it begins before infestation. Treatment generally must continue throughout the tree’s life and should be performed by a licensed pesticide applicator. An inspection can help determine whether treatment remains practical for a particular tree.

Spotted Lanternfly

Spotted lanternfly was first found in Greenville County in summer 2025. This invasive insect feeds on more than 100 host plants, including maples and young walnut trees. Unusual clusters or increased activity on susceptible plants warrant an evaluation.

Warning Signs That Call for a Tree Inspection

Pest and disease symptoms may begin in one part of a tree before spreading. Contact us when you notice a new or unexplained change, especially if it continues to worsen.

Warning signs worth having inspected include:

Leaves that yellow, brown, curl, wilt, or drop out of season
Dead branches or thinning sections of the canopy
Holes, splits, peeling areas, or unusual marks in the bark
Clusters of insects, larvae, or repeated insect activity
Fungal growth or other abnormal material on the trunk or branches
Shoots emerging from the trunk or base of a declining tree

Call at the first sign of illness or pest damage. Early identification can provide more options than waiting for extensive dieback.

Reducing Future Pest & Disease Risks

Prevention begins with the conditions in which a tree is growing. Soil and tissue testing can reveal which nutrients a tree needs and whether the soil is providing them, allowing us to base recommendations on the tree’s actual condition.

Corrective tree and shrub pruning removes problematic growth without leaving unnecessary weak points that can invite insects or disease. Regular inspections help track developing symptoms, while properly placed mulch protects the root zone without covering the trunk or visible root flare. Preventive care should also account for wind, rain, drought, flooding, and storm damage that may leave a tree more vulnerable.
