Per Hoboken City Code, property owners are responsible for caring for street trees and tree pits in front of their property, as well as all vegetation on their private property. Spotted Lanternfly (Lycorma delicatula) have been increasing in prevalence in Hudson County.
Spotted Lanternfly feed on the plant sap of many different plants including grapevines, maples, black walnut, and other important plants in NJ. As the Spotted Lanternfly feeds, it excretes honeydew (a sugary substance) which can attract bees, wasps, and other insects. The honeydew also builds up and promotes the growth for sooty mold (fungi),which can cover the plant, and eventually kill the plant. Although not directly harmful to animals and humans, the insect can greatly impact agricultural crops and hardwood trees.
The Spotted Lanternfly lays eggs on the bark of certain trees, most commonly the tree of heaven (Ailanthus altissima), or any flat surface such as rocks, lawn furniture, firewood, boats, pallets or anything left outdoors, some of which can be transported to new locations. Adult egg laying starts in September through December and egg masses contain 30-50 eggs. It is important to Stomp Out the adult Spotted Lanternfly (pictured above) to prevent them from egg masses.

Spotted lanternfly have been seen throughout Hudson County and Hoboken has seen massing of adult Spotted Lanternfly in certain parks.
The City is working with a certified arborist and NJ Licensed Tree Expert from Almstead Tree, Shrub & Lawn Care on an Integrated Pest Management (IPM) approach for managing the Spotted Lanternfly in City parks. Almstead is currently conducting site surveys of all City-owned parks for massing of Spotted Lanternfly.
All individual treated trees will be flagged with standard 72-hour no entry flags to inform the public. Please do not touch flagged trees.
All insecticide applications will be as limited as possible taking an IPM approach (rather than broad spraying) and performed by a NJ Licensed Commercial Pesticide Applicator.
