Make Sure You Keep An Eye Out For This Insect & How To Get Rid Of Them!

The Spotted Lanternfly (SLF), with its striking appearance, may seem like a harmless addition to the world of insects. However, this invasive pest has become a serious threat to agriculture, plants, and ecosystems.

Originating from Asia, the spotted lanternfly was first discovered in Pennsylvania in 2014 and has since spread across several U.S. states, wreaking havoc wherever it lands.

If you live in an affected area or are simply interested in learning how to protect your surroundings, this article provides everything you need to know about the lanternfly and how to combat its spread.

What Is the Spotted Lanternfly?

The spotted lanternfly, scientifically known as Lycorma delicatula, is an invasive planthopper native to parts of China, India, and Vietnam. It was unintentionally introduced to the U.S. through shipping containers, and now poses a serious threat to crops, particularly grapes, apples, and hops.

Lanternflies feed by sucking sap from plants, leading to stunted growth, reduced fruit production, and sometimes the death of the plant. While they don’t harm humans directly, the economic and environmental damage they cause is significant.

Identifying Characteristics

  • Adults: The adult lanternfly is about an inch long, with grayish wings that are speckled with black spots. The underwings display bright red and black bands, giving the insect a distinctive look when in flight.
  • Nymphs: Before reaching adulthood, nymphs go through four stages. Early nymphs are black with white spots, while later stages turn bright red with black patches.
  • Egg Masses: In the fall, females lay eggs in clusters that resemble smudges of mud. Each egg mass contains 30-50 eggs and can be found on almost any surface, from tree bark to vehicles.

Why Should You Be Concerned About Lanternflies?

The spotted lanternfly poses a serious risk to agricultural industries. In states like Pennsylvania, New Jersey, and Virginia, the insect has devastated vineyards and orchards, leading to significant economic losses. But it’s not just farmers who need to be worried—lanternflies can invade residential areas, infesting backyard trees, ornamental plants, and gardens.

These insects secrete a sticky substance called honeydew, which promotes the growth of sooty mold, a black fungus that can damage plants and leave behind unsightly residue on surfaces like patios, cars, and outdoor furniture.

Economic Impact

  • Agriculture: The wine, orchard, and lumber industries have reported substantial losses due to SLF infestations.
  • Property Damage: Homeowners have dealt with annoying infestations that affect both the appearance and health of outdoor plants and structures.

How Lanternflies Spread

One of the most concerning aspects of the spotted lanternfly is how easily it spreads. Adult lanternflies are capable of long-distance flight, but what makes them even more mobile is their ability to hitch rides on vehicles, outdoor equipment, and even firewood.

This makes it difficult to control their population, as they can easily travel from one location to another. Egg masses, which are laid on various surfaces in the fall, can be transported to new areas without people even realizing it.

Key Ways of Spread

  • Human Transport: Moving outdoor objects such as lawn furniture, firewood, and equipment can inadvertently spread SLF.
  • Natural Spread: Lanternflies can fly short distances and spread within a region.

Signs of an Infestation

If you’re worried about lanternflies taking over your yard or garden, it’s crucial to know the tell-tale signs of an infestation. Catching them early can make it easier to prevent damage.

Look Out For:

  • Egg Masses: In late summer and early fall, check for mud-like smudges on trees, rocks, outdoor furniture, or vehicles. These are often found in sheltered areas.
  • Nymphs and Adults: From late spring to late summer, keep an eye out for both nymphs and adult insects, especially around trees and plants.
  • Plant Damage: Lanternflies weaken trees and plants by feeding on sap, which can lead to wilting, yellowing leaves, and reduced growth.
  • Honeydew and Sooty Mold: As lanternflies feed, they excrete honeydew, which coats leaves and structures, promoting mold growth.

How to Prevent Lanternfly Infestations

Prevention is key to stopping the spread of spotted lanternflies. Since they often hitch rides on vehicles and outdoor equipment, taking proactive measures can greatly reduce the chances of an infestation.

Tips for Prevention:

  • Inspect Vehicles and Outdoor Equipment: Before moving or storing items, check them for egg masses or lanternflies. If you find eggs, scrape them off and destroy them.
  • Avoid Transporting Firewood: Always buy firewood locally. Moving firewood from infested areas can easily spread lanternflies to new locations.
  • Use Traps: Several traps, including sticky bands and circle traps, can be placed around trees to catch nymphs and adults.

Effective Ways to Get Rid of Lanternflies

Once you have an infestation, it’s important to act quickly. The earlier you deal with the problem, the better chance you have of reducing their numbers and minimizing damage.

DIY Methods:

  • Egg Scraping: Destroy egg masses by scraping them off with a knife or card into a container filled with rubbing alcohol.
  • Sticky Bands: Wrap tree trunks with sticky tape to catch nymphs as they climb.
  • Soapy Water: Spray soapy water directly onto the insects, which can kill them on contact.
  • Home Remedies: Neem oil and vinegar sprays can also deter SLF populations.

Chemical Options:

  • Insecticides: For larger infestations, using insecticides can be effective. Make sure to use products that are specifically labeled for lanternflies, and follow the instructions carefully.
  • Systemic Treatments: Applying systemic insecticides to trees and plants allows the pesticide to be absorbed into the plant’s tissues, killing lanternflies when they feed.

How to Safeguard Your Trees and Plants

Lanternflies primarily feed on trees like maple, oak, and willow, but they can attack a wide variety of plants. To protect your plants, it’s important to focus on both prevention and treatment.

Tree Protection Tips:

  • Remove Ailanthus Trees (Tree of Heaven): This tree species is a favorite of lanternflies. Removing them from your yard reduces the attractiveness of the area to SLFs.
  • Prune Infested Branches: If a tree shows signs of infestation, pruning affected branches can help slow the spread.
  • Fertilize and Water: A healthy tree is better equipped to resist damage from pests. Keep your trees well-watered and fertilized to support their health.

When to Call in Professional Help

Sometimes, DIY methods just aren’t enough to fully control a large lanternfly infestation. If you’re dealing with a serious problem or want to ensure long-term protection, professional pest control services may be the best option.

When to Call a Pro:

  • Severe Infestations: If your yard or garden is overwhelmed with SLFs, professionals can apply stronger, commercial-grade insecticides.
  • High-Value Crops or Trees: If you have valuable plants or crops, it’s worth investing in professional treatments to ensure they remain protected.

What You Can Do to Help Stop the Spread of Lanternflies

Everyone has a role to play in stopping the spread of spotted lanternflies. While homeowners and gardeners can take steps to manage them locally, there are broader actions we can all take to prevent them from invading new regions.

Actionable Steps:

  • Report Sightings: If you spot a lanternfly outside of known infested areas, report it to your local agricultural extension office.
  • Participate in Community Efforts: Many communities are organizing volunteer efforts to remove lanternfly egg masses and set up traps.
  • Spread Awareness: Educate your neighbors and friends about the dangers of lanternflies and how to prevent their spread.

While the spotted lanternfly may be small, its impact is anything but. By staying vigilant, taking preventative measures, and acting swiftly to eliminate infestations, you can protect your plants, property, and the environment from this destructive pest.
