The Spotted Lanternfly (Lycorma delicatula) has quickly become one of the most talked-about pests in New York State. If you live in Albany County, you may have seen the headlines or heard neighbors mentioning these invasive insects. While they are a significant concern for our local ecosystem, there is no need to panic—but there is a need to be informed and proactive.
As your local tree care experts, we want to help you understand exactly what the Spotted Lanternfly (SLF) is, why it matters, and what you can do to protect your property this season.
What is the Spotted Lanternfly and Why is it a Problem?
The Spotted Lanternfly is an invasive planthopper native to parts of Asia. Unlike many common pests that might only bother a single species of plant, the SLF is a “generalist” feeder. It uses its piercing-sucking mouthparts to feed on the sap of over 70 different plant species, including maples, walnuts, and various fruit-bearing trees.
This feeding process drains the tree of vital nutrients, leaving it stressed and highly susceptible to disease or secondary pest infestations. Perhaps even more damaging is the waste they produce: a sticky, sugary substance called “honeydew.” This honeydew coats leaves, trunks, and anything underneath the tree, which quickly encourages the growth of sooty mold. This black, fungi-like growth blocks sunlight from reaching the leaves, hindering photosynthesis and, in severe cases, contributing to the decline of the tree.
How to Identify the SLF: A Seasonal Guide
The SLF changes appearance drastically throughout the year, which can make them tricky to identify. Here is what to look for in the Capital District:
- Egg Masses (Late Fall to Spring): This is the most critical time for intervention. Look for small, gray, mud-like patches on smooth bark, rocks, outdoor furniture, or even rusty metal. When fresh, they look like a smear of gray plaster. As they age, the covering cracks and resembles a splotch of mud. Once the eggs hatch, they leave behind rows of tiny, brownish, seed-like capsules.
- Nymphs (Late Spring to Mid-Summer): Early-stage nymphs are small (about a quarter-inch long), black, and covered in bright white spots. As they grow into their final nymph stage (usually by mid-summer), they turn a striking red with black stripes and white spots.
- Adults (Late Summer to First Frost): The adults are about one inch long. When at rest, their wings are a light, grayish-tan with black spots. When they fly or feel threatened, they flash vibrant, hidden red wings at the base.
The “Hitchhiker” Phenomenon
One of the biggest reasons the SLF has spread so rapidly from Pennsylvania into New York is their ability to “hitch a ride.” They are not strong fliers, but they are master stowaways. They lay their eggs on cars, trailers, firewood, and outdoor gear. If you are traveling through an area known for high SLF populations, take a moment to inspect your vehicle and gear before heading home to Albany.
The Tree of Heaven: The SLF’s Favorite Snack
If you have a Tree of Heaven (Ailanthus altissima) on your property, you have a magnet for the Spotted Lanternfly. This invasive tree is the insect’s preferred host and a critical part of its reproductive cycle.
-
Identifying Ailanthus: Look for trees with smooth, gray bark that resembles the skin of a cantaloupe. They have long, compound leaves with 10 to 40 leaflets. A tell-tale sign is the smell: when crushed, the leaves and twigs emit a rancid, peanut-butter-like odor.
-
Management: Managing the Tree of Heaven is a primary strategy for SLF control. If you identify these on your property, please reach out to an ISA-certified arborist to discuss safe removal or systemic treatment options. Simply cutting them down without professional guidance often causes them to send up vigorous “suckers” or sprouts, making the problem worse.
What Should You Do If You Find One?
1. Identify and Report
If you suspect you have found a Spotted Lanternfly—especially in an area where they haven’t been widely reported yet—take a clear photo. You can report your sighting directly to the New York State Department of Agriculture and Markets. This data helps experts track the spread and allocate resources for control.
2. The “Scrape and Destroy” Method
During the winter and early spring, if you find an egg mass on your property, take a plastic card or a stiff putty knife and scrape them off. You must scrape them into a container filled with rubbing alcohol or hand sanitizer to ensure the eggs are destroyed. Simply scraping them onto the ground is not enough; they can still hatch.
3. Professional Intervention
While DIY methods are great for individual egg masses, managing a mature infestation requires professional equipment and knowledge. We utilize:
- Systemic Soil Treatments: This is an effective way to protect high-value ornamental trees. The treatment is absorbed into the tree’s vascular system, making the sap toxic to the insects.
- Targeted Canopy Sprays: When populations are high, we use specialized, environmentally conscious sprays to knock down adult populations before they can feed and lay more eggs.
Protect Your Landscape, Protect Your Investment
Your trees are more than just part of the scenery; they are an investment in your property value and your local environment. You don’t have to face the threat of the Spotted Lanternfly alone. By staying vigilant and working with a professional tree service, you can keep your landscape healthy and resilient.
