Spotted Lanternfly Control in Western Massachusetts and Connecticut

How Spotted Lanternflies Damage Trees and Shrubs

The damage caused by a spotted lanternfly infestation isn't always immediately visible. These insects use piercing mouthparts to extract sap directly from plant tissue, and the damage builds up over multiple feeding sessions during the season. By the time any decline is visible, the plant has often been stressed for weeks.

The signs our technicians look for during a property assessment include:

• Wilting or weeping branches – Active sap extraction stresses vascular tissue and reduces the tree's ability to move water and nutrients, causing branches to droop or weep even without visible wound sites.
• Honeydew buildup on leaves and surfaces – Spotted lanternflies excrete excess sugar as honeydew, which coats leaves, bark, outdoor furniture, and hardscaping beneath infested trees. Our technicians note the extent and location of honeydew deposits to gauge the density of the active population.
• Sooty mold growth – Honeydew provides a food source for black sooty mold fungi. When our team identifies sooty mold during an inspection, it confirms sustained feeding activity rather than a passing infestation.
• Egg masses on flat surfaces – Between October and early spring, spotted lanternflies lay seed-like egg masses on tree bark, stone, outdoor furniture, and even vehicles. Locating egg masses on your property helps our technicians assess overwintering populations and plan the timing of early-season treatments.
• Visible adult populations in late summer and fall – Adults emerge in late July and become increasingly active through October. Large congregations on trunks and lower branches are a reliable indicator of an established population requiring treatment.

Each of these signs explains how our technicians develop your treatment plan, including which property areas to focus on and the timing of each application.

Our Spotted Lanternfly Treatment Program

Effective spotted lanternfly control involves working with the pest's life cycle, not against it. A single treatment at the wrong time of year may temporarily lower populations but allows the next generation to rebound. American Pest Solutions employs a three-treatment yearly program timed precisely to interrupt spotted lanternfly development at each critical stage.

The three treatment windows are:

• May – Targeting early-stage nymphs before populations establish feeding sites and begin expanding across the property.
• August – Targeting late-stage nymphs and emerging adults during the period of peak feeding pressure, when plant stress is at its highest.
• October – Targeting adult populations ahead of egg-laying to reduce the number of overwintering egg masses that will hatch the following spring.

Treatment applications focus on tree trunks, bark surfaces, the ground-level zones beneath tree canopies, shrubs and ornamental plantings, and non-fruit-bearing vines known to attract spotted lanternflies. Products are applied to create a residual barrier on surfaces where these insects congregate and travel.

Our team adheres to all EPA label guidelines for each application and carefully avoids treating fruit-bearing plants and flowering or blooming vegetation to protect pollinators. If your property has areas that need special attention, our technicians note them during the initial assessment and modify the plan as needed.
