Spotted Lanternflies Are Established — Management Matters More Than Panic
The spotted lanternfly (Lycorma delicatula) is an invasive planthopper that feeds on many plants and can become a major nuisance around homes, vineyards and landscapes. It first became established in the United States in Pennsylvania and later spread into New Jersey and other states.
The practical goal today is not to pretend a single homeowner can eradicate spotted lanternflies from the region. It is to reduce local numbers, limit movement to new locations, protect high-value plants when needed and manage the conditions that support heavy activity.
Know What You Are Looking For
Spotted lanternflies look very different as they develop. Early nymphs are black with white spots. Later nymphs develop red coloring. Adults have gray forewings with black spots and bright red coloring visible on the hindwings when opened.
Egg masses can be laid on trees, stone, outdoor furniture, trailers, vehicles and many other hard surfaces. Fresh masses may look like a smear of gray mud; older masses can look cracked and dry.
What Damage Do Spotted Lanternflies Cause?
Spotted lanternflies use piercing-sucking mouthparts to feed on plant sap. Heavy feeding can stress plants, and the insects excrete sugary honeydew that coats surfaces below them. Honeydew can support sooty mold growth and create a sticky mess on patios, decks, vehicles and plants.
The pest is especially important to grape production. Around residential properties, the biggest complaints are often nuisance numbers, honeydew and repeated activity on favored host plants.
What New Jersey Homeowners Can Do
Skip Homemade Spray Recipes and Blanket “Safe” Claims
Older online advice often recommends homemade soap, oil or vinegar mixtures. These are not automatically safe for plants, pollinators or other organisms, and unlabeled pesticide uses can create avoidable problems.
When using a pesticide, use a product labeled for the intended site and pest and follow all directions. NJDA notes that insecticides remain one of the more effective tools for significant spotted lanternfly pressure, but treatment should be targeted rather than automatic.

Spotted Lanternfly FAQs
Should I scrape spotted lanternfly egg masses?
Yes. Destroying accessible egg masses can reduce the number that hatch locally. Follow current NJDA guidance for disposal.
Should I cut down tree-of-heaven?
Tree-of-heaven is a preferred host and invasive plant, but simply cutting it can stimulate root sprouts. Use current extension or NJDA guidance for proper removal.
Can spotted lanternflies be completely kept off one property?
No. NJDA notes that adults move between properties and host plants. Management can reduce local pressure but cannot stop every insect from arriving.
Are sticky bands recommended?
Wide sticky bands can capture birds and other wildlife. If trapping, use methods designed to reduce non-target capture, such as recommended circle traps or properly protected bands.
