What to Do If You Spot Them
The images showing large groupings of SLF on tree trunks (the nymphs, which have different life stages that are black with white spots and later red with white and black spots before becoming winged adults) and an adult on a surface are classic indicators of an infestation.
If “They Are Here” in your backyard, take action:
-
Kill Them: The common advice from agricultural departments is simple and direct: “Squish it, stomp it, smash it.” Every SLF you kill prevents it from reproducing and causing more damage.
-
Report It: This is crucial. Agricultural departments are tracking the spread of SLF to implement management strategies. Take a picture, note the location, and report your sighting to your state’s department of agriculture or local extension office. Many states have dedicated online reporting forms.
-
Identify and Manage Host Plants: If you have Tree-of-Heaven on your property, consider removing it, as this is their primary attractant. Be aware of other vulnerable plants in your yard and monitor them closely.
-
Check Before You Move: SLF are notorious hitchhikers. They lay egg masses (which look like smears of mud) on vehicles, campers, outdoor furniture, and other equipment. Before traveling from an infested area, thoroughly inspect everything to prevent spreading them to new locations. Look for nymphs and adults on your vehicle as well.
The arrival of the spotted lanternfly is not just a nuisance; it’s a threat to ecosystems and key industries. By being vigilant and taking action, you can help slow the spread and protect our environment
