Columbus, OH – Eleven Ohio counties are now quarantined as part of ongoing efforts to curb the spread of the spotted lanternfly (SLF). Counties affected include Columbiana, Cuyahoga, Erie, Franklin, Hamilton, Jefferson, Lorain, Lucas, Mahoning, Muskingum, and Ottawa.
According to the Ohio Department of Agriculture (ODA), the quarantine was implemented after multiple life stages of SLF, including egg masses, were found in these counties. Freezing temperatures typically kill adult SLFs, but microclimates may preserve some, allowing them to become active again when temperatures rise.
While adult SLFs die off in winter, their egg masses survive and can be laid on various surfaces, not just plants. Residents are urged to report suspected sightings of SLF egg masses through ODA’s Plant and Pest Reporter or the Great Lakes Early Detection Network. These steps aim to prevent the further spread of the invasive species to non-infested areas across the state.
Egg masses can be difficult to spot, blending into their surroundings, making early detection critical in the fight against SLF.
