Ohio Expanded Spotted Lanternfly Quarantine Statewide

Live Poll

Do you feel responsible for removing invasive spotted lanternfly egg masses found on your own property?

In February 2026, Ohio officials implemented a statewide quarantine covering all 88 counties to manage the spread of the spotted lanternfly. This expansion follows the initial identification of the invasive species within the state in 2020.

Why it matters

The spotted lanternfly poses a significant threat to agricultural crops and native plant life across the region. Establishing a comprehensive quarantine helps manage the spread of this invasive insect as it continues its life cycle.

The quarantine now encompasses 88 Ohio counties, a significant increase from the previous 18. Officials indicate that spotted lanternflies have been present in North America since 2016.

The players

Ohio Department of Agriculture

This state agency is responsible for overseeing agricultural health and regulatory policies across Ohio.

The details

Residents are encouraged to manage infestations through physical removal, horticultural oils, or chemical insecticides, though the state no longer requires reports of sightings. Egg masses, which are laid from October through December, can be destroyed by scraping them into soapy water or rubbing alcohol.

2016: Spotted lanternfly first detected in North America.
2020: Spotted lanternfly first identified in Ohio.
February 2026: Statewide quarantine expanded to 88 counties.
October through December: Spotted lanternfly breeding and egg-laying season.
April: Lanternfly nymphs begin hatching.

The Big Picture

This policy follows a containment pattern set by the 2016 spotted lanternfly detection in North America, which has forced state agencies to adapt their agricultural quarantine policies. The expansion marks a shift in regional strategy as the pest continues to move through the state.

Property owners should remain vigilant for egg masses during the winter months, as physical removal remains the most effective management strategy. Since officials no longer track sightings, individual intervention through scraping or chemical use is the primary method for protecting local foliage.

The takeaway

Management of this invasive species relies heavily on early detection and the physical destruction of egg masses before they hatch in the spring. Residents can limit the pest's spread on their own properties by utilizing simple methods like rubbing alcohol or soapy water.
