Spotted Lanternfly in Ohio: What Stark and Summit County Homeowners Should Do Now

Spotted lanternfly is now established in Ohio, and the whole state sits under an Ohio Department of Agriculture quarantine. The insect does not bite, sting, or damage your house. What it does is feed in crowds, coat whatever is underneath in sticky honeydew, and lay egg masses on anything outdoors from September until the cold kills it.

That last part is why this month matters. An egg mass scraped off your maple in September is up to fifty lanternflies that do not hatch in your yard next spring.

Is Spotted Lanternfly Actually In Our Part Of Ohio?

Yes. On February 17, 2026, the Ohio Department of Agriculture put all 88 Ohio counties under a spotted lanternfly quarantine, replacing the 18-county quarantine that had been in place before. Summit County had already been added in a 2025 expansion. Stark, Portage, Wayne and Tuscarawas are covered by the statewide order too.

The quarantine is aimed at commerce, not at your back yard. It requires trees, nursery stock and similar material to be inspected or covered by a compliance agreement before they leave the state. The Ohio Department of Agriculture has also stopped asking residents to report sightings, because the insect is considered established here. Learning to recognize it and killing the ones you find is now the useful thing a homeowner can do.

What Does A Spotted Lanternfly Look Like In September?

By mid-September in Northeast Ohio you are looking at adults. The Ohio Department of Agriculture describes them as roughly 1 to 1.5 inches long with the wings closed and 1.5 to 2 inches across with the wings open. There is one generation a year, with four nymph stages before the adult, so the black-and-white spotted crawlers people saw in June are gone by now.

• At rest: grey forewings with black spots, folded like a tent over the body. Easy to mistake for a moth on bark.
• In flight or startled: a flash of bright red hindwing with black spots. That red is the giveaway.
• Movement: they hop more than they fly, and they cluster, often dozens on one trunk.
• Earlier stages: nymphs are black with white spots, and the last one before adulthood is black and red with white spots.

Their favorite host is tree of heaven, an invasive that grows fast along fence lines, railroad corridors and alley edges, the kind of neglected ground every older neighborhood has. If you have one on or near your property, that is where the crowds will be.

What Are The Grey Smears On My Tree, Grill, Or Trailer?

Those are egg masses, and finding them is the whole job this time of year. The Ohio Department of Agriculture describes a mass as 1 to 1.5 inches long and half an inch to three quarters of an inch wide, covered in a shiny waxy coating that starts white to grey and weathers into something that looks like a patch of dried mud. Penn State Extension puts each mass at 30 to 50 eggs, from a single female.

People expect to find them on trees. They are on trees, but the Ohio Department of Agriculture also lists logs, plants, stones, vehicles, campers, yard furniture, farm equipment, metal, signposts and other vertical surfaces. Anything flat, hard and outdoors is a candidate. Check the places nobody looks:

• The underside of the rail on a deck or a porch swing.
• Wheel wells, trailer hitches, and the frame of a camper or boat that has been parked since August.
• Firewood stacks, landscape stone, retaining walls, and the back of a fence panel.
• Grills, patio furniture, downspouts, and the shaded side of an outbuilding.
• Tree trunks above eye level, which is where most people stop looking.

Penn State Extension recommends scraping the masses off from September through May with a plastic card or a putty knife and scraping them into a bag or container of rubbing alcohol or hand sanitizer. It is slow, unglamorous work, and it is the one control measure a homeowner can do that clearly removes the next generation.

One more reason to look before you tow: a camper or a load of firewood is how this insect covers distance it could never fly.

Do Spotted Lanternflies Bite, Or Damage A House?

No. They do not bite or sting people or pets, and they are not wood-destroying insects. Nothing about a spotted lanternfly threatens your framing, your siding or your deck boards, which puts it in a completely different category from the eastern subterranean termite that actually does eat Ohio houses.

The damage is to plants and to your patience. Lanternflies feed on sap, and what they excrete is honeydew, a sugary liquid that rains down onto whatever is below the tree. It goes sticky on cars, decks and lawn furniture, and it grows black sooty mold. Ohio's concern at the state level is agricultural: grapes, hops and fruit trees. The Ohio Department of Agriculture points out that the state's grape and wine industry contributes more than six billion dollars in economic activity to Ohio every year.

Why A Lanternfly Year Turns Into A Wasp Problem

Here is the part that puts this in our lane. Honeydew is sugar sitting out in the open, and in late September, yellow jacket and wasp colonies are at their largest and hungriest of the whole season. A honeydew-coated deck rail, a sticky patio table, a puddle of it under a maple: all of that pulls stinging insects into the exact places your family sits.

Which is how a lanternfly year quietly turns into a stinging insect year. If nests are already established around the eaves, under the deck or in the ground near the tree line, that is a job for stinging insect control rather than a can of spray and a garden hose, particularly with ground nests you cannot see the shape of.

Washing honeydew off hard surfaces with soapy water, and keeping fallen fruit and open trash cleaned up, takes away a lot of the attraction on its own.

Can Pest Control Get Rid Of Spotted Lanternflies?

Not in the sense most people mean, and you should be skeptical of anyone who says otherwise. Lanternflies fly and hop in from the next street, the next wood lot and the back of a passing trailer. No treatment makes a property a place they will not land, and there is no perimeter you can draw around a yard that keeps a landscape-wide insect out of it.

What is realistic, and what actually helps in Stark and Summit County this fall:

• Scrape every egg mass you find, September through May. It is the only step that removes next year's insects instead of this year's.
• Deal with tree of heaven on your property. Talk to an arborist or your county extension office, because cutting one carelessly can produce a thicket of root sprouts.
• Handle the stinging insects the honeydew attracts, which is a real and treatable problem even when the lanternflies are not.
• Check campers, trailers and firewood before you move them. That is how this insect travels between counties.
• Skip the home remedies. Homemade sprays on landscape plants tend to kill the plant and the beneficial insects on it, and do very little to the lanternflies.

A recurring plan is not a lanternfly cure and we will not sell it as one. What our State Shield Essential plan does cover is the rest of what arrives in a Northeast Ohio autumn: ants, spiders, millipedes, centipedes, mice, rats, bees, wasps and seasonal invaders, across four visits a year spaced to break egg cycles rather than to spray once and hope. If pests come back between treatments, so do we, at no cost. It does not cover termites, which are handled separately.
