Spotted Lanternflies in Ohio: What Residents Need to Know for the 2025 Season

If you live in Ohio, you’ve likely heard the buzz—literally and figuratively—about the spotted lanternfly (SLF). Once a distant problem plaguing the East Coast, these invasive insects have officially arrived in the Buckeye State and are spreading fast. In fact, several counties in Ohio are now under active SLF quarantine as the state ramps up control efforts.

At Trap Spotted Lanternflies, we’re helping Ohioans fight back with safe, effective, and proven solutions to trap and eliminate SLFs—before they destroy trees, crops, and backyards.

The Spotted Lanternfly Is Now in Ohio—And It’s Not Leaving Quietly

The Ohio Department of Agriculture has confirmed SLF infestations in multiple counties, including:

  • Cuyahoga County (Cleveland area)

  • Franklin County (Columbus area)

  • Hamilton County (Cincinnati suburbs)

  • Summit and Lorain Counties

  • Portage County

  • And spreading fast into Northeast Ohio and Central Ohio

These bugs are targeting vineyards, maple trees, fruit orchards, and even backyard gardens—leaving sticky honeydew, black mold, and damage in their wake.

How Ohio Residents Can Stop the Spread

✅ 1. Learn to Identify SLF at All Stages

In Ohio, SLFs hatch in April–May and grow into winged adults by July. Key signs to watch for:

  • Egg masses on trees, siding, or yard equipment

  • Black nymphs with white spots crawling in spring

  • Red nymphs in early summer

  • Adult lanternflies with spotted wings by late summer

✅ 2. Report Sightings Immediately

If you see an SLF in Ohio, report it to the Ohio Department of Agriculture or use apps like Great Lakes Early Detection Network (GLEDN) to log sightings.

✅ 3. Remove Egg Masses Now

SLF egg masses can survive Ohio winters. Check:

  • Tree trunks (especially Tree of Heaven)

  • Fences, campers, trailers, and sheds

  • Firewood and outdoor tools
    Scrape and destroy the masses by submerging them in rubbing alcohol.

✅ 4. Install SLF Traps That Work for Ohio Conditions

Ohio’s mix of urban and rural environments demands a trap that’s tough, safe, and reliable. That’s why our trap at Trap Spotted Lanternflies is ideal for Ohio homeowners.

✔ Safe for Cleveland suburbs and Columbus city trees
✔ Won’t harm birds, squirrels, or pets
✔ Designed for wet spring and humid summer Ohio weather
✔ Works in residential, agricultural, and forested areas

Why Ohio Needs to Act Now

Ohio is at a critical tipping point. With the SLF population still manageable in many regions, early intervention is everything. Trapping nymphs in spring and adults in summer will drastically reduce the number of egg masses laid in fall—breaking the cycle and protecting Ohio’s trees.

Whether you’re in Dayton, Youngstown, Toledo, or Akron, every Ohioan can make a difference in slowing the spread of SLF.

Conclusion: Ohio, It’s Time to Trap

Ohio residents: it’s time to squash, stomp, and trap. Whether you own a home in Cleveland, manage vineyards in Geneva, or run a business near Columbus, you’re now on the front lines of this invasive species battle.
