What does Ohio's statewide spotted lanternfly quarantine mean for Avon homeowners?
Ohio is under a statewide spotted lanternfly quarantine (since February 2026), effective February 17, 2026, in all 88 counties. Its rules mainly cover regulated items, such as nursery stock and trees, leaving Ohio. For most Avon households the practical part is simple: check vehicles, trailers and outdoor gear for egg masses before trips, and destroy any you find.
Lorain and Cuyahoga counties were among the 18 counties under quarantine before the statewide order, so living inside the line is not new here. What changed in 2026 is that the entire state now sits inside it.
Businesses that move regulated items out of Ohio, such as nurseries, landscapers and tree services, need an ODA compliance agreement, permit or inspection certificate and should contact ODA's Plant Pest Control Section. Rules can change, so check ODA for current rules before you ship or haul anything regulated.
How do I spot tree-of-heaven on my property?
Tree-of-heaven (Ailanthus altissima) has long compound leaves made of many smooth-edged leaflets, each with one or two small notched bumps near its base, and crushed leaves smell like rancid peanut butter. It sprouts in dense thickets along fences, sheds and driveways. Sumac and black walnut look similar but have toothed leaflets and lack that smell.
On older Avon properties, look along the back fence rows and around barns and outbuildings. On newer lots, check the strip between the lawn and any field or woodlot. Female trees hold tan clusters of winged seeds into winter, which makes them easy to pick out after the leaves drop.
Cutting one down is rarely the end of it. Tree-of-heaven pushes up root sprouts after the trunk is cut, so removal usually needs a follow-up plan, and large trees near the house are arborist work. Some owners keep one treated tree as a monitored host while the rest come out; the technician can talk through the tradeoffs.
- Leaflets: smooth edges except for one or two small notches with a bump near the base
- Bark: smooth and pale gray, with light streaks that resemble cantaloupe skin on older trunks
- Smell: crushed leaves and twigs give off a strong, unpleasant odor
- Growth: crowded clumps of fast saplings along fences, foundations and pavement cracks
When are spotted lanternflies active in Lorain County?
Eggs laid the previous fall hatch in late spring, and black, white-speckled nymphs climb nearby plants into early summer. Red-marked late nymphs and the first adults follow in July. Adults feed into fall, and egg-laying runs from late summer until hard frost. Near Lake Erie, a milder fall may stretch that adult season a little longer.
That calendar decides the method. Young nymphs are small and easy to knock down with contact sprays. Adults move between trees, so treating the trees they feed on works better. Eggs can only be scraped, and they ride out lake-effect snow and January cold without trouble, which is why a winter scraping visit pays off in spring.
- Late spring into June: black nymphs with white spots
- July: red, black and white late nymphs, plus the first adults
- August to October: adults crowding host trees, with honeydew at its worst
- September until hard frost: egg masses laid on trunks, stone and outdoor items
- Winter: eggs only, and the easiest time to scrape them
Can spotted lanternflies hurt my family, pets or house?
Spotted lanternflies do not bite or sting, and they do not chew siding, decks or foundations. The trouble is honeydew: the sugary waste they drip coats patios, cars and plants, grows black sooty mold and can draw wasps and yellowjackets. Heavy feeding also stresses grapevines and young trees, especially during a dry summer.
Most calls from Avon come from people tired of scrubbing the deck rail or the car parked under a maple. Hosing honeydew off hard surfaces while it is fresh keeps mold from taking hold. If a yellowjacket nest has settled in near the feeding tree, wasp and hornet nest removal is handled as its own visit.
Why can't anyone promise to get rid of spotted lanternflies for good?
Adults fly, hop and ride on vehicles, so a treated yard sits inside a neighborhood and a county full of untreated trees. Treatment reliably lowers the number feeding and laying eggs on your property for the season. Keeping that number down year after year takes repeat visits, host-tree management and neighbors doing the same.
Be wary of anyone who promises a permanent fix. Ohio went to a statewide quarantine because this insect keeps spreading, and a single property cannot wall itself off from farm fields, rail lines and the I-90 traffic that is never far away in Avon.
What a season of work does deliver is a usable deck and a healthier tree: fewer insects on the trunk, less honeydew and fewer egg masses waiting to hatch next spring. That is the honest goal a technician will set with you.
