Spotted lanternfly was detected in Georgia for the first time in November 2024. The invasive planthopper, already established in over 15 states across the mid-Atlantic, New England, Midwest, and south-Atlantic regions, has now reached a state with significant agricultural stakes. Georgia’s grape, peach, and hardwood industries all fall within the pest’s target range.
What Georgia’s Detection Means
Early detection is the best-case scenario for managing spotted lanternfly. When a state catches the pest before populations explode, agencies, landowners, and homeowners have a much better shot at containing it. Georgia is now in that early window. The Georgia Department of Agriculture lists spotted lanternfly as a serious threat to grapes, hops, stone fruits, and hardwood trees, all of which have meaningful economic footprints in the state.
The pest’s primary host is tree-of-heaven, an invasive tree already widespread across the Southeast. Tree-of-heaven has light brown to gray bark with a cantaloupe-like texture and large compound leaves that can stretch 1 to 4 feet long, made up of many smaller leaflets along a central stem. If you have tree-of-heaven on your property, it’s one of the first places to look for spotted lanternfly activity.
How to Identify Spotted Lanternfly
Spotted lanternfly goes through one generation per year, cycling through four nymph stages, an adult stage, and overwintering egg masses. Knowing what to look for in each season makes a real difference in catching them early.
Eggs hatch starting in May. The earliest nymphs are small, about a quarter inch long, black with white spots. They stay active through July, and the second and third stages look similar. By the fourth nymph stage, the insects shift to a striking red with white spots and grow to about three-quarters of an inch. Adults appear later in summer, roughly an inch long with black-spotted pinkish-tan wings folded tent-like over their backs. When they spread their wings, the span reaches about 2 inches, and the hindwings reveal a bright red section with black spots. That flash of red is the most recognizable feature.
Mating begins in late August. Females lay eggs from September through November or until the first hard freeze. Each egg mass contains 30 to 60 eggs arranged in segmented rows about an inch long. Fresh egg masses are covered in a creamy white, putty-like substance that dries to pinkish-gray, then darkens to a muddy tan and starts to crack. Old egg masses are easy to overlook because they resemble a smear of dried mud on a tree trunk, rock, deck railing, or piece of outdoor equipment.
Insects Commonly Mistaken for Spotted Lanternfly
Georgia has several native insects that look similar at first glance. Before reporting a sighting, check a few key details. Adult spotted lanternflies have that distinctive combination of pinkish-tan forewings with black spots and red hindwings. Native moths like the giant leopard moth have white wings with black spots but lack the red hindwings entirely. Boxelder bugs share the red-and-black color scheme but are much smaller and shaped differently. If you’re unsure, a close-up photo of the insect with wings visible is the most useful thing you can provide when making a report.
How to Report a Sighting
If you spot what you believe is a spotted lanternfly or an egg mass in Georgia, report it to the Georgia Department of Agriculture. Take a clear photo if possible, note the location, and check the department’s spotted lanternfly page at agr.georgia.gov for the most current reporting instructions. Early reports from residents are one of the most effective tools for tracking how far the pest has spread.
Managing Spotted Lanternfly on Your Property
Property owners can take direct action at several points in the pest’s life cycle. In fall and winter, scraping egg masses off trees, fences, and outdoor surfaces is one of the simplest and most effective steps. Scrape them into a bag or container of rubbing alcohol or hand sanitizer to destroy them. Egg masses show up on all kinds of surfaces, so check firewood, vehicles, camping gear, and anything that’s been stored outdoors.
For trapping, funnel-style “circle traps” placed around tree trunks are the recommended option. Sticky bands have been used in other states but come with serious downsides. The adhesive catches pollinators, butterflies, birds, and small mammals indiscriminately. If you do use sticky bands, a wildlife barrier around the band is essential to reduce bycatch.
Contact insecticides can work on adults, especially since many feed on the lower parts of trees where they’re easy to reach with a direct spray. Systemic insecticides, which the tree absorbs and passes to feeding insects, can provide months of protection. One critical rule: never spray any insecticide on plants that are blooming, because it will kill pollinators visiting the flowers. Hiring a certified pesticide applicator is worth considering, particularly for large trees that need specialized equipment.
Removing Tree-of-Heaven
Because tree-of-heaven is the spotted lanternfly’s preferred host, removing it from your property can reduce the pest’s foothold. But this tree is notoriously difficult to kill. Simply cutting it down backfires. The tree responds aggressively by sending up large numbers of sprouts from the stump and root suckers from the surrounding root system, often making the problem worse than before.
The most effective approach is to apply a systemic herbicide first, wait about 30 days for symptoms to develop, and then cut the tree. Timing matters: mid to late summer, when the tree is pulling nutrients down to its roots, gives herbicides the best chance of reaching the root system and killing it. Cut-stump applications alone do not prevent root suckering.
For trees under 6 inches in diameter, a basal bark treatment works well. A concentrated herbicide mixture is sprayed around the base of the trunk from ground level to about 12 to 18 inches high. For larger trees, the hack-and-squirt method is effective: make downward-angled cuts spaced evenly around the trunk and immediately squirt herbicide into each cut. Leaving strips of living tissue between the cuts allows the tree’s own circulation to carry the herbicide down to the roots. Young seedlings can be hand-pulled when the soil is moist, but you need to get the entire root system. Even small root fragments left behind can generate new shoots.
Why Georgia’s Agriculture Is at Risk
Spotted lanternfly feeds by piercing plant tissue and sucking sap. It targets over 70 plant species, but the damage is most severe on grapevines, fruit trees, and hardwoods. Feeding weakens plants directly, and the insects excrete large amounts of a sticky substance called honeydew that coats leaves and surfaces below. Honeydew promotes the growth of sooty mold, which blocks sunlight from reaching leaves and further stresses the plant.
Georgia is the largest peach-producing state in the Southeast, and its wine industry has been growing steadily. Both crops fall squarely in the spotted lanternfly’s crosshairs. Hardwood forests, which support timber operations and ecosystem health across the state, are also vulnerable. The economic damage in Pennsylvania, where the pest has been established since 2014, offers a preview of what unchecked populations can do. Containment during these early stages of detection is Georgia’s best opportunity to limit that kind of impact.
