Experts are warning of a potential surge in spotted lanternflies this summer, urging the public to remain vigilant. The observed increase in egg mass counts in Berks County, Pennsylvania, has raised concerns about the possibility of a population rebound, according to entomologist Ben Hottel of Orkin. Despite the uncertainty of whether this increase will translate into a true population surge, the experts emphasize the importance of monitoring and preventing further spread of the invasive pests, which can damage plants and crops.
The spotted lanternflies, known for their ability to spread through human transportation, have already established populations in several northeastern states and are beginning to expand into other regions, including the Midwest and Southeast. The potential ecological and agricultural impact of their resurgence has prompted warnings from environmental authorities, highlighting the need for community involvement in pest control efforts.
While lanternflies pose a serious risk to plants and crops, they are not a danger to humans or animals, experts say. The insect does not sting, bite, or transmit disease. However, the National Park Service warns that these invasive insects could pose a threat to agricultural production. Once established in an area, the spotted lanternfly has the potential to dramatically affect forest ecosystems, agricultural production, and cultural resources.
Although the lanternfly prefers feeding on the exotic tree of heaven — which is also invasive, meaning it spreads quickly and harms local ecosystems, according to Hottel — it is an ‘indiscriminate pest’ that feeds on over 70 different plant species. They also excrete a substance that causes harmful mold growth on plants, the expert noted.
Pest services like Orkin recommend that homeowners remove young tree of heaven seedlings to prevent the spotted lanternfly from invading their property. Because the insect lays its eggs on hard surfaces like vehicles, firewood, bricks, stones and other items often moved outdoors, humans can easily, and unknowingly, transport the pest. This means lanternflies can spread more widely to new territories and cause more damage, Hottel warned.
While this might not sound significant, a large-scale die-off of native North American flora and fauna would have an impact on our local ecosystems in a big way. People who think they have seen a spotted lanternfly should call a local pest control office to assist with identification and to address concerns about infestation.
