The invasive spotted lanternfly has returned to the D.C. region this summer, and they’re everywhere, much to the annoyance of every single one of us. If you’re feeling triggered wondering how they could be back after we all stomped on so many, well, same, friends. So, here’s what you need to know!
Know Thy Enemy
Spotted lanternflies, scientifically known as Lycorma delicatula, are native to Asia. They were first spotted in Pennsylvania in 2014, and likely arrived on an overseas shipment. They’re planthoppers because they feed on the sap of plants, such as stone fruits, hardwood trees, and grapes. They lay eggs in the fall, and hatch in late spring or early summer. Over four life cycles, their coloring varies from black with white spots, red with white spots, and black-spotted with pinkish-tan wings.
How Badly is DC Affected?
While it’s difficult to pinpoint their exact numbers, sightings have surged. Spotted lanternflies are likely thriving in the area because they’re good hitchhikers. Transportation by human activity is the most common reason lanternfly populations grow and spread, as adult flies easily enter open car windows or truck beds and lay their eggs on any outdoor surface.
Since they have no natural predators in the U.S., their population is spreading unchecked, and it’s affecting trees, plants, and crops. Spotted lanternflies feed on the sap of their hosts, which affects their energy source, and their waste produces a fungus that can prevent a tree from growing and slowly kills the plant. But they’re not dangerous to humans or pets.
How to Get Rid of Them
- Experts recommend stomping adult lanternflies whenever you see them. Harsh, but necessary.
- If you find an egg mass in your backyard, smash it. Just be sure to scrape the mass into a plastic bag and douse with rubbing alcohol to ensure they’re really dead.
- Avoid spraying them with household products because that’s actually more harmful to your pets. Consult a professional if you have a — gulp — major undertaking.
- If you have one of the host plants, it’s time to say goodbye. This includes a tree-of-heaven, and they’re known to also feed on lilacs, Virginia creepers, roses, and blueberries.
- Before you hit the road, check your cars, trailers, and outdoor items for nests so you’re not contributing to the spread.
