Wormageddon hits the group chat
The Fall and Rise of Screwworm
America’s nightmare flesh-eating fly is back — and the comments are already fighting
TLDR: Screwworm, a parasite that eats living flesh, has returned to parts of the US for the first time in decades, reviving fears about cattle, wildlife, and costs. In the comments, people are split between blaming weak long-term planning, mocking the nightmare bug factory, and arguing over whether price panic is real or overblown.
The actual bug story is horrifying enough: screwworms, flesh-eating parasites that attack living animals, have turned up again in Texas and New Mexico after being mostly gone from the US for decades. The reason they were beaten back in the first place sounds like sci-fi with a cowboy hat on: officials bred huge numbers of male flies, sterilized them, and dropped them into outbreak zones so female flies would mate once, have no young, and the infestation would die out. It worked so well that a fly barrier was maintained down near the Darien Gap for years.
But in the comments, the bugs quickly became a side character in a much messier argument: was maintaining that barrier a smart long-term plan, or a cheap patch that was bound to fail? One commenter openly wondered whether it would have been better to team up with South American countries and wipe screwworm out everywhere instead of playing endless defense. Another came armed with numbers, saying the ongoing burden on cattle producers is about $10 per animal, which sounds manageable until you remember that “manageable” still means constant inspections and hassle.
And then came the internet’s favorite genre: gross-out comedy and price-gouging paranoia. One reader quoted the article’s unforgettable description of the old fly factory as a “76,000-square-foot artificial wound,” which is honestly the kind of phrase that makes a comment section stop and stare. Others swatted down any attempt to turn this into a lazy “they’re just raising prices” story, while one commenter dragged in the egg industry as Exhibit A for corporate nonsense. So yes, America may have a worm problem again — but the comments have a trust problem, a money problem, and absolutely no intention of staying calm about either.
Key Points
- •A screwworm case was detected on June 3, 2026, in a calf near La Pryor, Texas, followed by dozens more cases in Texas and New Mexico.
- •The article says this is the first U.S. screwworm infestation since the 1980s, excluding a contained outbreak in the Florida Keys in 2016.
- •The U.S. previously eliminated screwworm through the sterile male technique, which suppresses reproduction by releasing sterile male flies.
- •The USDA used the sterile male technique over several decades to eliminate screwworm from the United States, Mexico, and Central America.
- •Since the early 2000s, COPEG has maintained a screwworm barrier at the Darien Gap between Colombia and Panama by releasing millions of sterile flies weekly.
