Don’t.

If you ever spot this insect, experts say you should get rid of it immediately. Not because it bites or stings—but because it poses a serious threat to trees, crops, ecosystems, and local economies.

This insect is known as the Spotted Lanternfly, and despite its attractive appearance, it is one of the most destructive invasive species spreading rapidly across many regions.

In this article, we’ll cover everything you need to know:

• What the Spotted Lanternfly is

• Why it’s so dangerous

• How to identify it at every life stage

• Where it came from and how it spreads

• What to do if you see one

• How homeowners can help stop the invasion

By the end, you’ll understand why authorities urge people to act immediately when they encounter this insect.

What Is the Spotted Lanternfly?

The Spotted Lanternfly (Lycorma delicatula) is an invasive insect native to parts of China, Vietnam, and India. It was first detected in the United States in 2014 and has since spread at an alarming rate.

Despite its name, it is not a fly. It’s actually a type of planthopper that feeds on the sap of trees and plants. While a single insect may not seem dangerous, large populations can devastate entire landscapes.

Why It’s Considered Invasive

An invasive species is one that:

• Is not native to the area

• Spreads rapidly

• Causes harm to the environment, economy, or human health

The Spotted Lanternfly meets all three criteria.

Why This Insect Is So Dangerous

1. It Kills Trees and Plants

Spotted Lanternflies feed by piercing plants and sucking out sap. This weakens trees and plants, making them vulnerable to disease, pests, and environmental stress.

They attack over 70 plant species, including:

• Maple trees

• Oak trees

• Walnut trees

• Apple trees

• Grape vines

• Peach trees

For forests, orchards, and vineyards, the damage can be catastrophic.

---

2. It Threatens the Agriculture Industry

Farmers are especially worried about this insect.

Grapevines are one of its favorite targets, putting:

• Wine production

• Fruit farming

• Local agriculture jobs

at serious risk.

In heavily infested areas, vineyards have reported significant crop losses, increased pesticide use, and long-term plant damage.

---

3. It Spreads Incredibly Fast

One of the biggest dangers of the Spotted Lanternfly is how easily it spreads.

It lays egg masses on:

• Tree trunks

• Firewood

• Cars

• Outdoor furniture

• Shipping pallets

• Buildings

This means the insect can hitch a ride to new areas without anyone realizing it.

---

4. It Produces a Sticky, Smelly Mess

As lanternflies feed, they excrete a sugary waste called honeydew. This substance:

• Coats leaves, decks, and sidewalks

• Attracts wasps and ants

• Encourages black mold growth

Homeowners often notice the mess before they see the insects themselves.

---

How to Identify the Spotted Lanternfly

One of the reasons this insect spreads so easily is that many people don’t recognize it right away. Identification is crucial.

Egg Stage (Fall to Spring)

Egg masses:

• Look like gray or brown smears

• Are about 1–2 inches long

• Often resemble dried mud

You’ll find them on almost any outdoor surface—not just trees.

---

Nymph Stage (Spring to Early Summer)

Early nymphs:

• Small

• Black with white spots

Later nymphs:

• Bright red with black and white markings

This stage is extremely active and destructive.

---

Adult Stage (Late Summer to Fall)

Adults are the most recognizable:

• Gray wings with black spots

• Bright red and black hind wings

• About 1 inch long

When resting, they may look harmless—but they’re not.

---

Why You’re Told to Kill It Immediately

Many insects are protected or should be left alone. The Spotted Lanternfly is different.

No Natural Predators (Yet)

Because it’s not native, local predators don’t effectively control its population. This allows numbers to explode.

Rapid Reproduction

A single female can lay 30–50 eggs at a time, and multiple egg masses per season.

Environmental Impact

Left unchecked, this insect can:

• Alter forest ecosystems

• Reduce biodiversity

• Damage urban tree canopies

That’s why state and local agencies often recommend destroying the insect on sight.

---

What To Do If You Spot One

Step 1: Kill the Insect

Common methods include:

• Crushing it

• Using approved insecticides

• Trapping

(Always follow local guidelines.)

---

Step 2: Check for Egg Masses

Inspect nearby surfaces, especially:

• Trees

• Vehicles

• Outdoor furniture

Scrape egg masses into a container with alcohol or soap to destroy them.

---

Step 3: Report the Sighting

Many regions ask residents to report sightings to help track the spread. This information helps scientists and authorities respond faster.

---

How Homeowners Can Help Stop the Spread

You don’t need to be an expert to make a difference.

Inspect Before You Travel

Check:

• Your car

• Trailers

• Camping gear

• Firewood

before moving between regions.

---

Remove Host Trees

The Tree of Heaven, an invasive plant itself, is the lanternfly’s preferred host. Removing it can significantly reduce populations.

---

Use Tree Bands and Traps Carefully

Sticky bands can catch lanternflies, but they should be protected with mesh to prevent birds or other animals from getting stuck.

---

Common Myths About the Spotted Lanternfly

“It’s harmless to humans”

While it doesn’t bite, the damage it causes indirectly affects people through:

• Food prices

• Property damage

• Environmental loss

---

“It will die off on its own”

Unfortunately, invasive species rarely disappear without intervention.

---

“It’s too late to stop it”

While eradication may be difficult, slowing the spread absolutely matters.

---

Why Awareness Is So Important

Many invasive species succeed simply because people don’t know what to look for.

By learning to recognize this insect and acting quickly, everyday citizens become the first line of defense.

A single person destroying egg masses can prevent hundreds of new insects from hatching.

Final Thoughts: Don’t Ignore This Insect

The Spotted Lanternfly may look striking—even beautiful—but it is anything but harmless.

If you ever spot this insect:

• Don’t ignore it

• Don’t assume someone else will handle it

• Take action immediately

Stopping invasive species isn’t just the job of scientists or governments. It starts with awareness, responsibility, and small actions taken by individuals.

The next time you see a spotted, winged insect clinging to a tree or wall, remember:

Getting rid of it immediately could protect your trees, your community, and your environment.
