• The invasive spotted lanternfly has been confirmed in eight new Kentucky counties in 2025, bringing the total to 16.
• Native to China, these insects pose a significant threat to agriculture, including orchards, vineyards, and various trees.
• Spotted lanternflies damage plants by feeding on them and leaving behind a waste product that encourages mold growth.
• Officials advise residents to inspect their property for the bugs and their egg masses, especially around dusk.
• Sightings in Kentucky should be reported to the Department of Forestry or the University of Kentucky.

Entomologists have confirmed spotted lanternflies in eight more counties in Kentucky during 2025, according to a recent announcement.

These include Fayette, Franklin, Harrison, Pendleton, Robertson, Scott, Trimble and Woodford. The invasive insect was first found in the commonwealth in October 2023, in Gallatin County, and spread to counties including Boone, Campbell, Carroll, Grant, Henry, Kenton and Owen in 2024.

Here’s what to know.

What is a spotted lanternfly?

In short, the spotted lanternfly is a moth-like bug that’s not supposed to be in the U.S. The bugs tend to be red with black and/or white spots on their wings, according to the Department of Agriculture.

They’re native to China and first showed up in the U.S. in 2014. They’ve mostly been found in the Northeast and Mid-Atlantic, the USDA reports, but they’ve also been found in Indiana, Ohio and West Virginia.

One of the things that makes them so risky as an invasive species is that the eggs are thought to travel well, on everything from packages being shipped to moving boxes on U-Hauls. 

Why are spotted lanternflies dangerous?

Spotted lanternflies can pose a major threat to the things such as orchards, vineyards and logging facilities. How? They tend to swarm and devour what they land on quickly, causing serious damage. 

Their “waste product” — known as “honeydew” — can also attract molds and other bugs that further damage plants.

They pose a threat, according to the USDA, to everything from almonds, apples and hops to maple, oak and pine trees and more.
