U.S. officials are warning that invasive insects and other organisms pose a growing risk to farms, forests and the broader food supply. Early coverage described how pests can hitchhike on everyday items—from firewood and vehicles to online‑ordered seeds—and outlined simple preventive steps for travelers and homeowners, such as declaring agricultural goods, buying from reputable sources and cleaning equipment.

Later reporting expanded the picture, noting that invasive species are linked to a majority of recent global extinctions and cost the United States tens of billions of dollars annually. The focus sharpened on high‑profile pests such as the spotted lanternfly and emerald ash borer, which threaten fruit trees, hardwoods and water infrastructure. USDA’s Animal and Plant Health Inspection Service is coordinating with state partners, businesses and the public to detect, contain and eradicate these threats before they cause further ecological and economic damage.
