Oh good, screwworms are back (2025)

# Summary The New World Screwworm, a parasitic fly that lays eggs in living animals' wounds causing them to be eaten alive, was successfully eradicated from North America through the sterile insect technique (SIT) developed in the 1930s—a process that eliminated the pest from the US by the 1960s and pushed it south of Panama by the 1990s. However, the screwworm has made a comeback in recent years due to COVID-19 disruptions, border issues, and institutional failures that compromised the maintenance of a biological barrier in Panama that had kept the pest contained for decades.
