Wineries across Indiana are on alert as the invasive spotted lanternfly spreads closer to key vineyard regions. While the insect has not yet reached most local vineyards, experts believe it’s only a matter of time before it does.
Spotted lanternflies, first found in the U.S. in 2014, feed on over 20 tree species and grapevines by sucking sap, which weakens plants and encourages mould. They were first detected in Indiana in 2021 and have now been seen in 13 counties, especially in the northeast.
Jim Butler of Butler Winery expects lanternflies to reach his vineyard within a few years. He worries that relying on outsourced grapes would affect the quality and style of his wines. Cody Leaderbrand of Owen Valley Winery fears rising management costs and says these could raise prices for customers.
The insect is known to travel by hitchhiking on trucks, trains, and RVs. Will Drews from the Indiana Department of Natural Resources (DNR) says busy areas like stadiums, truck stops, and university campuses are high-risk zones due to increased movement and tree-of-heaven infestations — the pest’s preferred host.
Wineries in Pennsylvania have used heavy insecticide applications to manage outbreaks. Butler already sprays for Japanese beetles once a year, but might have to increase treatments. However, Leaderbrand urges caution, noting that excessive insecticide use could harm other living organisms through environmental runoff.
Drews and the DNR are monitoring and treating affected areas. They apply insecticides to host trees and remove egg masses to prevent spread. Residents can report sightings through the DNR website, ideally with a photo or a frozen specimen for confirmation.
If spotted lanternflies settle in Indiana, vineyard quality and wine production may suffer significantly — potentially changing the landscape for the state’s wineries.
