If you see a spotted lanternfly, the state of Ohio is encouraging you to kill it. Adult lanternflies grow to be about an inch in length, with light colored forewings marked with black spots and "lacey" black ends. The hindwings are red, black and white, but they are covered when at rest. Spotted lanternflies are considered an invasive pest. They were first found in Ohio five years ago and have been found in several areas of the state. What's the issue with spotted lanternflies? The insect can do serious damage to plants. They are known to be a pest that feeds on grapes, hops stone fruits, tree of heaven and other agriculturally important plants. What is the state's response? The Ohio Department of Agriculture first announced a quarantine in October 2021 to combat the spread of the pest. SLF is designated as a destructive plant pest under Ohio law, which increases inspections and restricts the movement of certain items from infested counties in Ohio and other states into non-infested counties. What counties are under quarantine? As of April 2025, there are 18 counties under quarantine, including Franklin County. A map of the counties can be seen here. Those in quarantined counties should not move outdoor lawn furniture, lawn equipment or firewood without inspecting them first. People are also encouraged to inspect their vehicles before leaving the county. Jonathan Shields, an agriculture inspection manager with ODA, says the pests can hitch a ride on cars and can stay latched onto them even when vehicles are driving up to 60 mph. Can spotted lanternflies hurt people or pets? No. Shields says they are not harmful to people. They do not sting or bite. They will not hurt your pet if they eat some.
