Effective Ways to Kill Spotted Lanternflies:
- Squish and Destroy: The simplest method is to kill them by hand. Stomp on them, use a fly swatter, or wear gloves and crush them. Focus on nymphs (young SLF) and adults.
- Scrape Egg Masses: During the fall and winter, locate and scrape off egg masses. Double bag them and dispose of them in the trash. This prevents the next generation from hatching.
- Tree of Heaven Removal: Spotted lanternflies prefer to infest and live in the tree of heaven (Ailanthus altissima), an invasive species in New York City. Although technically a weed, they are one of the most common trees we remove in the area. Removing these trees can help reduce their population in your area. Be sure to consult with a professional for safe removal. If you live in the Bronx or Manhattan, please call us for a free estimate.
- Avoid Sticky Bands: While sticky bands can trap nymphs, they also harm beneficial insects and other wildlife like birds. Instead, use alternative methods like those mentioned here. There are special traps available that target lanternflies without harming other creatures.
- Circle Traps: Build or purchase circle traps designed to capture SLF as they move up and down trees.
- Insecticides: Use insecticides containing the active ingredients dinotefuran, carbaryl, or bifenthrin. Follow label instructions carefully and prioritize targeted application to avoid harming beneficial insects.
- Systemic Insecticides: Consult a professional pest service for application.

Why Spotted Lanternflies Are a Problem:
- They feed on over 70 plant species, weakening them and making them susceptible to disease.
- They excrete a sticky honeydew, which promotes mold growth and attracts other pests.
- They cause significant damage to agricultural crops and valuable trees.
Integrated Pest Management (IPM) for Long-Term Control:
Combine multiple methods for best results. For example, use tree banding and traps alongside targeted insecticide applications. Monitor SLF populations regularly and adjust your strategies accordingly.
Join the Fight Against SLF:
Report SLF sightings to your local authorities and participate in community efforts to control this pest. Call a local tree service to have the host tree removed, and the lanternflies will go away. We offer a free onsite estimate to remove the host tree of heaven and can have them removed quickly.
