Spotted lanternfly is a new invasive insect found in southeastern Pennsylvania, northern Virginia, and western New Jersey. It is a voracious insect that can feed on over 75 plants, including economically important crops like grapes, hops, apples, and other tree fruit. It also feeds heavily on deciduous trees like black walnut, maple, and poplar, having potentially significant impacts to the timber industry. Its preferred host is an invasive plant, tree-of-heaven, that is currently being targeted for spotted lanternfly control and monitoring throughout the northeast region. Penn State Extension educators and researchers provide an update on the status of spotted lanternfly, answer questions about how to remove and treat tree-of-heaven, and provide an update on ongoing research at Penn State and elsewhere.
