Sticky Deck in Springboro? The Spotted Lanternflies Are in the Tree Above It

The call almost never starts with the bug. It starts with the deck. Somebody in Springboro walks out with a cup of coffee, sets it on the railing, and it sticks. The boards feel tacky under bare feet. The patio chairs have a shine on them that wasn't there in August. Then they look up, and one tree at the edge of the yard is covered in gray, spotted insects packed onto the trunk so tight the bark looks like it's moving.

That sticky film is honeydew, the sugary waste spotted lanternflies (Lycorma delicatula) leave behind as they feed on tree sap, and it lands on whatever sits under the tree they've claimed. Around Springboro, that's usually one tree, not the whole yard. Finding it is most of the work in spotted lanternfly control in Springboro this fall, because the adults crowding that trunk right now are the same ones that'll lay next spring's eggs.

Why are Springboro spotted lanternfly calls up so much this year?

Joey, one of our techs covering the northern end of the market, didn't hedge when we asked if he was seeing more of them than last year. His answer was a 100% increase. Lanternfly calls have roughly doubled, and the Dayton side of his territory is running heavier than Cincinnati, even though the two are only 30 to 45 minutes apart.

He doesn't claim to know exactly why Dayton gets it worse. The bug is working its way west across the country, and most insects move the same way: in packaging, in trailers, on the semis hauling freight between states. His read is that the wood side of the local economy plays a part. There are several big wood manufacturers and lumber yards around Dayton, and lumber, pallets, and crating are exactly the kind of cargo an egg mass can ride in on. That's a field theory, not a lab finding, but it lines up with how researchers say this insect gets around. University of Georgia entomologists point out that eggs laid on rail cars, trailer trucks, and campers hatch in brand new places the following year.

Springboro sits right in the middle of that. It's a short drive south of Dayton, mostly in Warren County with a slice reaching into Montgomery County, and both counties play by the same rules now. The Ohio Department of Agriculture put all of Ohio under quarantine effective February 17, 2026, and with that order the state stopped asking residents to report sightings. That surprises people, since a couple of years ago every news story ended with "report it." The bug is established here now, and the job has shifted from reporting it to managing it. We covered the quarantine itself, and why the Dayton counties were in the first group, in our post on why Dayton yards are already inside the spotted lanternfly quarantine.

Why do spotted lanternflies pile onto one tree?

Joey hears the same thing on almost every call. The customer says the lanternflies have taken over their tree. Singular. They might be scattered across every tree on the lot, but most of them are stacked up on one trunk, or in one corner of the property. If you see a bunch of them in one tree, that's where you'll find the majority.

Researchers have a name for it. Entomologists at the University of Georgia call these "hot" trees, and note that the tree right next door can have no adults on it at all. A field study run by the USDA's Forest Pest Methods Laboratory found the grouping follows a sequence in late summer and fall. Females gather on a tree first, several weeks before mating. Males show up once mating season arrives, and the group keeps using that same tree into egg laying. The researchers also found lanternflies land more often on trees that already have a crowd, so one busy trunk tends to pull in more. Separate work in the journal Environmental Entomology shows they stay loyal to particular trees while they're moving around, and that what's inside a tree nutritionally affects which suburban trees get hit.

So the tree you're staring at isn't random, and it won't sort itself out by next week. It's the tree the local population picked, and it keeps drawing new arrivals as long as the adults are alive.

It's also not always the tree people expect. Tree-of-heaven is the favorite host, and if you've got one, it's worth dealing with. But in a Springboro subdivision, the hot tree is often a maple. Penn State Extension lists maple, black walnut, birch, and willow among the trees they prefer, and our own national team notes they'll go after most trees. A red maple the builder planted fifteen years ago can end up doing the job a tree-of-heaven does in an old rail yard.

How does the sticky film end up on your deck?

Lanternflies don't chew leaves. Joey describes the mouth as needle-like, basically a tiny straw the insect burrows into the bark to pull sap out. They take in more sap than they can use, and the leftover sugar comes out the back end as honeydew. His description of the feel is about as good as it gets: grab a cut piece of honeydew melon, and that sappy, tacky feeling on your hand is what the deck boards feel like.

That's why the deck is worth paying attention to. Penn State's guidance on treating ornamentals says the honeydew problem mostly comes from the adult stage, and the volume tracks with how many lanternflies are on the tree. Their management guide says on sunny days you can actually watch it falling out of an infested tree like a light rain. A few scattered lanternflies along the back tree line won't glaze your deck. If the deck is tacky, the hot tree is close to where you actually live, not out at the property edge.

Once the honeydew builds up, black sooty mold grows on it. UGA describes it blackening tree trunks and whatever sits underneath, which on a Springboro lot usually means deck boards, pavers, and the car. The sugar also pulls in ants, bees, and wasps and yellow jackets, so a lanternfly tree over a patio in October tends to come with stinging insects working the railing. The tree shows it too. UGA notes the bark can weep sap where the adults have been feeding, and some homeowners mistake that for a disease.

Why do wooded Springboro lots get hit harder than open ones?

Joey's short answer is foliage. It's a sucking insect that lives on sap, so the more trees and brush a property has, the more lanternflies it can hold. An open lot with a couple of young street trees doesn't give them much. A lot that backs onto a tree line gives them a whole menu, plus a hot tree to settle on.

That's a lot of Springboro. The newer neighborhoods west of the historic district went in on former farmland, and plenty of those back yards end right where the woods or a field-edge tree line starts. Clear Creek runs through town with trees along it, and a lot of lots back up to wooded greenspace and drainage easements. The lanternflies build up in the trees behind the yard, and the hot tree is often the one at the edge of the lawn, closest to the house. That's the one dripping on the deck.

It's the same edge that shapes other pests here. Ticks work that back tree line for their own reasons, which we got into in our post on where tick season starts in Springboro, and the town's groundwater drives mosquito pressure in ways we laid out in why pest control in Springboro follows the water. Lanternflies are just the newest pest to use that wooded edge, and they lean on it hardest in the fall.

What do Springboro homeowners usually try first?

Most people have already tried a few things by the time they call us, and none of them are crazy. The first move is almost always stomping and swatting. Joey doesn't knock it, and neither does Ohio State University Extension, whose Jefferson County overview says squashing them works best when numbers are low. The trouble is a hot tree isn't low numbers. When there are hundreds on the trunk, you can stomp all afternoon and the tree looks the same the next morning.

Next comes the hose. Rinsing the deck is worth doing, because the longer honeydew sits, the more mold it grows. But the tree keeps producing it as long as adults are feeding up there, so the film is back in a day or two. It's cleanup, and people tend to mistake it for control.

Then somebody brings up the chainsaw. If the hot tree is a tree-of-heaven, taking it out is reasonable, as long as it's done right so it doesn't come back from the roots, which we explained in the earlier Dayton post. But the U.S. Fish and Wildlife Service is blunt about it: removing tree-of-heaven won't remove spotted lanternflies, because there's plenty more for them to eat. And if the hot tree is a healthy shade maple, cutting it down over a seasonal insect is a big trade. Penn State notes that taking a tree out can stop honeydew on whatever sits under it, but tree removal hasn't been shown to shrink the population itself.

The last thing people usually try is a hose-end spray from the hardware store. Those can knock down what they hit, and OSU Extension lists insecticidal soaps, horticultural oils, and contact products as options, with a reminder to follow the label. The problem is reach. Penn State points out that lanternflies move from plant to plant a lot, so treating any single plant gives you unpredictable protection. And standing on the lawn with a hose-end bottle, you're not getting thirty feet up a trunk or into the tree line behind the fence.

What does spotted lanternfly treatment actually look like on a Springboro property?

It starts with a walk, and most of that walk is looking up. Joey's rule of thumb is that if a bunch of them are sitting in one tree, that's where the majority are, guaranteed. So the first job is confirming which tree is the hot one, then checking the trees around it and the wooded edge behind the lot for smaller groups.

From there, our spotted lanternfly control service goes where the insects actually are. Adults feed mostly on trunks, so the trunk and lower canopy of the hot tree get the most attention, along with the trees nearby and the brushy cover where they rest. The treatment helps kill lanternflies on contact and continues to deter them for up to 21 days, which matters because new adults keep showing up at a hot tree. For heavier pressure, Barrier Treatment Plus is the step up. It runs on the same kind of schedule as our mosquito barrier treatment, so a lot of Springboro customers just fold lanternflies into the service they already have.

We're not going to promise a lanternfly-free yard in a statewide quarantine zone with a wooded lot behind the fence. What we can do is knock down the population on your hot tree, cut the honeydew over the spaces you use, and keep the next wave from settling in. A big maple you'd hate to lose can also be a candidate for a systemic trunk treatment from a certified arborist. That's arborist work, and it pairs fine with what we do on the rest of the property.

A couple of habits help too. Penn State recommends not parking or storing things under an infested tree, which saves your car's paint and keeps you from giving an egg-laying female a free ride. If there's outdoor furniture, a grill, or a trailer sitting near the hot tree, look it over before you move it anywhere.

We're also hearing from more newer builds and HOA communities around Dayton that want prevention in place before anything shows up, a full integrated pest management approach instead of waiting for a problem. For single-family homes, Squad Home Shield and Complete Home & Yard cover the house and yard on one plan. For HOA common areas and condo communities, our commercial services handle the shared tree lines and greenspace.

When should Springboro homeowners act on spotted lanternflies?

Right now, and then again in winter and spring. Fall is the part people underestimate.

The Ohio Department of Agriculture says lanternflies start laying eggs in October, and adults stick around from July into December. Put those together and the tree covered in adults this month is where next year's population is being set up. The females that grouped there in late summer are finishing their feeding and starting to lay. Every adult knocked down on that trunk in October is one that won't leave an egg mass on your siding, your fence, or the underside of your patio table.

Here's how the year plays out on a typical Springboro yard.

October into the first hard freezes, treat the hot tree and the trees around it, keep the deck rinsed, and stop parking under it.

Late fall through winter, go looking for egg masses. USDA APHIS says a new egg mass starts out resembling damp gray putty and dulls to brown over time, with 30 to 50 eggs inside, and they turn up on trees, bricks, stones, fences, grills, and vehicles. Start with the hot tree and whatever sits near it, since that's where the egg-laying females spent the fall. Our Dayton quarantine post walks through how to scrape and destroy them.

In spring, the eggs hatch and the black, white-spotted nymphs start feeding on new shoots. That's the next window for spotted lanternfly treatment, before the nymphs grow into the adults that start the whole cycle over.

Plenty of people can't tell which tree is the hot one, or whether the gray patch on a fence post is an egg mass or just dirt. Both are easy calls for us to make on a walk-through.
