Welcome to Fox Pest Control’s ultimate guide on Spotted Lanternflies! Whether you’re dealing with an infestation or just curious about these tiny creatures, we’ve got all the information you need. From facts and types to behaviors and Spotted Lanternfly treatment options, this guide covers it all. Let’s dive in!
What Do Spotted Lanternflies Look Like?
What Are Spotted Lanternflies?
Spotted lanternflies (Lycorma delicatula) might look cool with their flashy wings, but don’t be fooled—they’re bad news! These invasive bugs are a real headache, especially for plants and trees. With their gray wings covered in black spots and bright red underwings, they stand out, but what really makes them notorious is their love for plant sap. That’s right, they suck the life out of trees, crops, and gardens, making them a serious pest.
Spotted lanternflies are one of those bugs you can’t miss! They’re super colorful and have a pretty cool look. Here’s what you’ll notice about them:
- Adults: These guys are about the size of your pinky finger and are mostly gray with black spots on their wings. When they spread those wings, you’ll see some bright orange-red coloring underneath, which gives them a little extra flair. It’s like they’re showing off their “underwing” party trick!
- Nymphs: The baby lanternflies, or nymphs, start off looking pretty different. They’re small and black with white spots, which makes them look a little like tiny, walking polka dots. As they grow, they change to a red and black combo, so they’re constantly getting more stylish.
- Eggs: You might spot their eggs in clusters that look like little blobs of dried mud. They love sticking them to tree trunks, rocks, or even your outdoor furniture.
How Spotted Lanternflies Got Their Name
The “spotted” part is easy to figure out—those black spots all over their wings definitely make them stand out! As for the “lanternfly” part, that’s because when they open their wings, the reddish-orange color underneath looks a bit like the glow of a lantern, especially when they take flight.
Even though they look cool, don’t let their looks fool you! These little guys are invasive and can damage plants by sucking up tree sap, so keep an eye out if they’re in your area!
Where Can You Find Spotted Lanternflies in the US?
Spotted lanternflies are making their way across the U.S., and if you live on the East Coast, you’ve probably heard all about them. These little pests first showed up in Berks County, Pennsylvania, in 2014, and since then, they’ve been spreading like wildfire. They’ve hit states like New Jersey, New York, Delaware, Maryland, Virginia, Ohio, and even Indiana. They love the warm weather and tend to hang out in places like vineyards, orchards, and wooded areas.
The lanternfly population has exploded over the years, hitching rides on cars, trucks, and shipping materials, making it tough to slow them down. Scientists and pest control experts are working hard to keep them in check, but it’s definitely an ongoing battle! So, if you’re in one of these areas, keep an eye out for these colorful critters.
Where Did Spotted Lanternflies Come From?
Spotted lanternflies are originally from parts of China, India, and Vietnam, where they’ve been part of the local ecosystem for centuries. Over there, they have plenty of natural predators—birds, spiders, and other insects—that help keep their population in check. These predators have evolved alongside lanternflies and have no problem making a meal out of them.
But when these pesky pests hitched a ride to the U.S. (likely on goods and shipments) and arrived in Pennsylvania in 2014, they left all those natural enemies behind. With no real threats to slow them down, they spread like wildfire, thriving in warm climates and causing major damage, especially in vineyards, orchards, and wooded areas. They suck the sap out of trees and plants, weakening them and making them more vulnerable to disease.
So, why aren’t U.S. birds stepping up to the plate and eating them? Turns out, it’s not that simple.
Why Won’t Birds in the U.S. Eat Spotted Lanternflies?
Because spotted lanternflies aren’t native to the US, they’re a bit of an acquired taste. One reason might be that they snack on the tree of heaven (Ailanthus altissima), an invasive tree from China that contains bitter, possibly toxic compounds. When lanternflies feed on it, they absorb these chemicals, making them foul-tasting or mildly toxic to predators. In Asia, some birds and insects have evolved to tolerate these toxins—but in the U.S., our native predators haven’t, so they avoid eating them. It’s like taking one bite of something nasty and deciding, “Never again!”
- They Don’t Look Like Food: Most North American birds don’t recognize spotted lanternflies as prey. Birds rely on instinct and experience when choosing what to eat, and since lanternflies are a brand-new species here, most birds don’t see them as something edible.
- That said, a few species—like gray catbirds, blue jays, and even chickens—have been spotted eating lanternflies. But so far, it’s not happening at a level that’s helping control the infestation.
- They’re Quick & Sneaky: Lanternflies aren’t just sitting around waiting to get eaten. They have strong legs and can jump away fast, making it tricky for slower-moving birds to catch them. Plus, their wing colors can serve as a visual warning, signaling that they might not be a tasty or safe snack.
- Nature Needs Time to Adapt: In Asia, predators have had thousands of years to learn that spotted lanternflies are food. In the U.S., they’ve only been around for a decade—way too short for birds and other predators to naturally adapt. Over time, some species may start to eat them more, but for now, they’re spreading without much resistance.
What’s Being Done to Stop Spotted Lanternflies?
Since nature hasn’t caught up yet, scientists are exploring other ways to control lanternfly populations. One promising idea? Introducing natural enemies from Asia, like parasitic wasps that specifically target spotted lanternflies. These tiny wasps could help reduce their numbers without harming native species, but researchers are still studying the potential impact before bringing them in.
Until then, spotted lanternflies will keep causing trouble. So, if you see them in your area, the best thing you can do? Squash them on sight! Then call Fox to help protect against these invasive pests.

Do Spotted Lanternflies Bite, Sting, Damage Property, or Spread Disease?
Good news: Spotted lanternflies don’t bite or sting humans, so you don’t have to worry about getting nipped by one. Bad news: They’re still a massive headache for anyone with trees, gardens, or crops.
How Do Spotted Lanternflies Cause Damage?
Even though they’re harmless to people, spotted lanternflies wreak havoc on plants by feeding on their sap. They use their piercing-sucking mouthparts (kind of like a tiny straw) to drain nutrients from trees, vines, and crops. Over time, this weakens the plants, making them more vulnerable to disease, drought, and even death.
Some of their favorite targets include:
- Fruit trees (like apple, cherry, and peach)
- Vineyards (especially grapevines, which can suffer major losses)
- Ornamental trees (such as maple, walnut, and willow)
- The tree of heaven (their favorite invasive snack)
The Sticky, Moldy Aftermath
As if stealing nutrients wasn’t bad enough, spotted lanternflies also leave behind a sticky, sugary substance called honeydew. This gunk coats leaves, branches, outdoor furniture, cars—you name it. And where there’s honeydew, sooty mold is sure to follow.
Sooty mold is a black, grimy fungus that thrives on sugary surfaces, covering leaves and blocking sunlight. This can stunt plant growth and make outdoor spaces look (and feel) pretty gross.
Do They Damage Homes or Buildings?
While they don’t chew through wood or burrow into walls like termites or carpenter ants, spotted lanternflies can be a nuisance for homeowners. During peak season, they gather in massive swarms on trees, decks, patios, and even siding. Their honeydew can make outdoor surfaces sticky and attract other pests like wasps and ants looking for a sweet snack.
Do Spotted Lanternflies Spread Disease?
Nope! Spotted lanternflies don’t carry diseases that affect humans or pets. But they are a serious threat to agriculture, especially vineyards, where they can cause devastating losses. A severe infestation can lead to withered crops, lower yields, and major financial hits for farmers.
Spotted lanternflies may not bite, sting, or spread disease, but they sure know how to cause chaos. If you see them, the best thing to do is squash them, scrape off their eggs, and report sightings to local agricultural authorities. The sooner we stop them, the better!
Life Cycle of Spotted Lanternflies
Let’s take a peek at how these pests grow up—from tiny eggs to full-blown plant destroyers.
Egg Stage: The Sneaky Start
In the fall, female spotted lanternflies lay their egg masses on just about any surface they can find—tree trunks, rocks, fence posts, firewood, even patio furniture. Each egg mass contains 30-50 eggs and looks like a grayish blob covered in a waxy, mud-like coating. This protective layer helps camouflage the eggs, making them hard to spot.
Eggs sit tight through the winter, surviving snow, ice, and freezing temperatures, just waiting for the warmth of spring to hatch. If you spot these egg masses, scrape them off and destroy them before they get the chance to hatch—every single one you eliminate means fewer lanternflies next season!
Nymph Stage: The Tiny Trouble-Makers
By late spring (usually April to June), the eggs hatch into tiny, wingless nymphs—and this is when the real damage begins. Spotted lanternfly nymphs go through four growth stages, or instars, before becoming adults:
- First three instars (black nymphs with white spots): These tiny jumpers are about the size of a tick and are super mobile, hopping from plant to plant as they feed.
- Fourth instar (red nymphs with black and white spots): Just before adulthood, they take on a striking red-and-black pattern, making them a bit easier to spot.
Nymphs aren’t picky eaters—they feed on a variety of plants, sucking the sap out of leaves and stems. They can’t fly yet, but they make up for it by being fast, agile jumpers, making them tricky to catch.
Adult Stage: The Flying Menace
By late July to August, the nymphs complete their final molt and become fully grown adults. Now, they’ve got wings—and they’re ready to cause even more chaos.
- Appearance: Adult spotted lanternflies are about an inch long with gray forewings and bright red hindwings that flash when they fly.
- Behavior: While they can fly, they actually prefer to hop and glide short distances, often launching themselves from tree trunks or buildings.
- Feeding: They use their piercing-sucking mouthparts to tap into tree sap, which weakens trees and leaves behind sticky honeydew (which attracts sooty mold and other pests).
The Roles of Adult Spotted Lanternflies: Eat, Mate, Repeat
Once they hit adulthood, spotted lanternflies have two main priorities:
- Feasting on plants – They cluster in large groups and drain trees of their sap, especially targeting grapevines, fruit trees, and hardwoods.
- Laying eggs for the next generation – By September through November, females start laying their egg masses, ensuring a fresh batch of trouble for next year.
The Cycle Starts Again
After laying eggs, adult lanternflies die off in late fall, but their eggs survive the winter, waiting to hatch in the spring and start the whole cycle over again.

Mistaken Identities: Bugs That Look Like Spotted Lanternflies
Spotted lanternflies have a pretty unique look, but that doesn’t stop people from mistaking them for other insects. Their bright red wings, gray bodies, and black spots might remind you of moths, butterflies, or even stink bugs—but these pests are in a category of their own.
Spotted Lanternflies or Moths?
At first glance, you might think a spotted lanternfly is a moth, especially when it’s at rest with its grayish wings folded over its back. But unlike moths, which have fuzzy bodies and feathery antennae, spotted lanternflies have a sleek, smooth exoskeleton and short, straight antennae.
Also, moths are pollinators, meaning they help plants by spreading pollen as they move from flower to flower. Spotted lanternflies? Not so much. These guys aren’t helping your garden grow—they’re draining the life out of it.
Spotted Lanternflies or Stink Bugs?
Spotted lanternflies and stink bugs share a few things in common:
- They’re both invasive species in the U.S.
- They both have wings and can fly (sort of).
- They both gather in large numbers during the warmer months.
But there’s one key difference—stink bugs smell awful when squished, while lanternflies just leave a sticky mess. Instead of releasing a foul odor like their stinky cousins, lanternflies excrete honeydew, a sugary liquid that attracts mold and other pests.
Spotted Lanternflies or Butterflies?
Their bright red-and-black hindwings might make you think they’re some kind of butterfly, but don’t be fooled. Unlike butterflies, which are beneficial pollinators, spotted lanternflies don’t help plants at all—in fact, they actively harm them by sucking out sap and weakening trees.
Butterflies gracefully flutter through the air, while spotted lanternflies tend to hop and glide in short bursts. They’re much more awkward in flight, which can be a quick clue that you’re dealing with a pest rather than a pretty pollinator.
How to Tell If You’re Looking at a Spotted Lanternfly
Not sure if the bug you spotted is a lanternfly? Look for these telltale signs:
- Gray, spotted wings when at rest
- Bright red hindwings when flying
- Piercing-sucking mouthparts (like a tiny straw for drinking sap)
- Hopping and gliding movements instead of steady flying
Behavior, Diet, and Living Conditions of Spotted Lanternflies
These guys love warm weather and are often found in vineyards, orchards, and wooded areas. They’re super social and tend to gather in big groups, which makes infestations easy to spot. Their diet? Pure plant sap, with a special love for the invasive tree of heaven.
Nesting Habits: No Home Sweet Home Here!
Some insects go all out when it comes to building nests—think bees with their honeycombs or ants with their underground tunnels. But spotted lanternflies? They’re lazy freeloaders. Instead of crafting a cozy little nest, they slap their eggs onto whatever surface is nearby and call it a day.
Where Do They Lay Their Eggs?
The short answer? Anywhere and everywhere. Spotted lanternflies aren’t picky—they’ll glue their egg masses onto:
- Tree trunks and branches (their favorite spot)
- Rocks and fence posts
- Cars, trucks, and trailers (yes, they’ll hitch a ride!)
- Patio furniture, decks, and even houses
Basically, if it’s a flat, hard surface, they see it as the perfect baby nursery. This is one of the reasons they spread so fast—they hitch rides on outdoor equipment, firewood, and vehicles without anyone noticing.
What Do Spotted Lanternfly Eggs Look Like?
Their egg masses look like grayish blobs covered in a mud-like coating. At first, they’re soft and shiny, but over time, they dry out and crack, making them blend in even more. If you don’t know what to look for, you could walk right past dozens of them without realizing!
Why Is This a Problem?
Since they don’t build nests or hide their eggs underground, spotted lanternflies have no natural protection—which means their survival strategy is all about quantity over quality. Each female lays 30-50 eggs per mass, and with thousands of them reproducing at once, it’s no wonder they’re taking over so fast. We’re going to talk in just a minute about what you can do to help with this issue.
How Do Spotted Lanternflies Communicate?
Spotted lanternflies may look flashy, but when it comes to communication, they’re surprisingly silent. Unlike crickets that chirp or bees that buzz, these pests don’t make a peep—at least, not in a way humans can hear.
Vibrations: The Lanternfly Language
Instead of using sound, spotted lanternflies send out silent messages through vibrations. They tap or drum their bodies against surfaces—like tree trunks or leaves—to send signals through the material. Think of it like a secret Morse code that only other lanternflies can pick up.
Scientists believe they use these vibrations for a few key reasons:
- Finding Mates – Males and females “chat” through vibrations to locate each other during mating season.
- Coordinating Movement – Ever notice how they seem to swarm together on trees? They use vibrations to help synchronize their movements, making them harder to stop.
- Warning Signals – Some researchers think they might also use vibrations to alert others about danger, though this isn’t fully proven yet.
Because spotted lanternflies rely on vibrations, scientists are exploring ways to disrupt their “conversations” as a possible control method. If researchers can figure out how to jam their signals, they might be able to throw off their ability to find mates and slow their spread.
What Do Spotted Lanternflies Eat?
Spotted lanternflies might look pretty, but their eating habits are bad news for trees and crops. These little sap-suckers have a serious sweet tooth—except instead of candy, they crave plant sap.
Basically, if it’s got sap, spotted lanternflies are interested! But they’re not just nibbling on any old leaf—they go straight for the good stuff inside trees and plants. Some of their favorite snacks include:
- Trees: Maple, walnut, oak, willow, and their absolute favorite—the invasive tree of heaven (Ailanthus altissima).
- Crops: Grapes, apples, hops—pretty much anything that makes wine, cider, or beer. (Farmers are NOT happy about this!)
- Other Plants: They’ll also munch on ornamental plants and garden favorites, making them a headache for homeowners too.
How Do Spotted Lanternflies Eat?
Unlike caterpillars that chew through leaves, spotted lanternflies have a totally different way of eating. Instead of munching, they use piercing-sucking mouthparts that work like tiny built-in straws. Here’s how it works:
Spotted lanternflies feed by stabbing their needle-like mouthparts into a plant’s bark to access the nutrient-rich sap inside. As they suck out the sap, they drain the plant’s energy, weakening it over time. But the damage doesn’t stop there—these pests also leave behind a sticky substance called honeydew, which attracts mold and other pests, creating an even bigger mess for plants and the people trying to protect them.
Over time, this feeding frenzy weakens trees and crops, making them more vulnerable to disease. In extreme cases, plants can wither, stop producing fruit, or even die.
Why Is This a Problem?
Because they feed on so many different plants, spotted lanternflies cause millions of dollars in damage every year—especially to vineyards, orchards, and farms. Plus, their honeydew attracts black sooty mold, which coats leaves and blocks sunlight, making it even harder for plants to survive.

Signs of a Spotted Lanternfly Infestation
Not sure if you have a spotted lanternfly problem? These pests aren’t exactly shy, and they leave behind plenty of evidence. If you know what to look for, you can spot an infestation early and take action before they cause serious damage. We’ve already mentioned a few of these, but let’s look a little closer.
- Big Clusters of Bugs on Trees, Buildings, and Outdoor Surfaces: One or two spotted lanternflies might not seem like a big deal, but these pests love to gather in large groups. If you see a swarm of them clinging to tree trunks, fences, or even the side of your house, you’ve got a problem. They’re most active in late summer and fall when they’re feeding, mating, and laying eggs.
- Egg Masses Stuck to Trees, Walls, or Furniture: Spotted lanternflies aren’t picky about where they lay their eggs, so keep an eye out for their grayish, mud-like egg masses on:
- Tree trunks and branches
- Siding, fences, and deck railings
- Cars, trailers, and outdoor equipment
Egg masses are one of the biggest ways these pests spread, hitching rides on vehicles and outdoor gear to new locations. If you find them, scrape them off and destroy them!
- Sticky Honeydew Residue on Plants, Cars, or Patios: Spotted lanternflies suck sap from plants, and all that feeding leads to a nasty side effect—honeydew. This sticky, sugary substance drips down onto leaves, sidewalks, patio furniture, and even cars, making everything feel gross and attracting other pests like ants and wasps.
- Black Sooty Mold Growing on Leaves or Surfaces: Where there’s honeydew, sooty mold isn’t far behind. This dark, powdery fungus grows on surfaces coated in honeydew, covering leaves, branches, and even outdoor furniture. Not only does it look bad, but it also blocks sunlight and weakens plants, making it even harder for them to recover from an infestation.
What You Can Do About Spotted Lanternflies
Spotted lanternflies might be small, but they cause big problems—and they multiply fast! The good news? You can help stop them before they spread even more. Since these pests go through different life stages, tackling them at every step is the best way to keep their numbers in check.
- Scrape Off and Destroy Egg Masses (Fall & Winter)
Spotted lanternflies lay their eggs in late summer and fall, and these egg masses stick around all winter, waiting to hatch in the spring. You can stop hundreds of new lanternflies before they even hatch by scraping off and destroying their eggs. Here’s how to do it:
- Look for grayish, mud-like egg masses on trees, fences, walls, and outdoor furniture.
- Use a stiff card, putty knife, or even a credit card to scrape them off.
- Drop them into a container of rubbing alcohol or soapy water to make sure they’re destroyed.
- Catch and Crush Nymphs (Spring & Early Summer)
Once the eggs hatch, tiny black nymphs with white spots start crawling around, looking for plants to feed on. They can’t fly yet, which makes them easier to catch and kill.
- Eliminate Adults (Late Summer & Fall)
By late summer, spotted lanternflies have wings and are much harder to catch—but that doesn’t mean you can’t stop them! The simplest method? Stomp them! These bugs are strong jumpers, but if you’re quick, you can crush them before they escape.
Other ways to remove adult lanternflies:
- Use a fly swatter or bug zapper racket for better aim.
- Set up circle traps on trees to catch them as they move up and down.
- Spray them with soapy water (this can kill them by clogging their breathing holes).
- Report Infestations to Local Officials
Since spotted lanternflies are an invasive species, many states have programs in place to track and control their spread. If you see a large infestation, make sure to take a picture and report it to your state’s department of agriculture or a local pest control agency. Your report helps scientists and spotted lanternfly pest control experts find and fight new infestations.
