Top 5 Things You Need to Know About the Flesh-Eating Screwworm Invasion Now
- This is not a sci-fi movie: A parasitic screwworm outbreak has been confirmed in the Florida Keys, with officials finding the larvae feeding on live tissue in a critically endangered Key deer. The infestation is causing extreme suffering and has a 100% fatality rate in untreated animals.
- The "screwworm" gets its name from its appearance: The larvae look like tiny, corkscrew-shaped wood screws, and they bury into the open wounds of living warm-blooded animals—including pets and livestock—feeding on the host and causing deep, festering holes.
- The real nightmare is that it's not just external: These maggots can burrow into the eyes, ears, nasal passages, and even the mouths or skulls of animals. Once inside, they destroy living tissue from the inside out, leading to massive infection, septic shock, and death.
- How it got here: The outbreak is linked to a single, infected stray dog imported into the area, which slipped through quarantine checks. Since screwworm flies can travel miles a day and lay hundreds of eggs, the entire ecosystem is now at risk of a rapid, unstoppable spread.
- What you must do: Inspect every wound on your pets, farm animals, and even yourself daily. If you see tiny, cream-colored, segmented larvae with dark bands, DO NOT touch them. Isolate the animal and contact your state vet immediately—delayed action means widespread animal culls and a potential national emergency.
