New World Screwworm Loses Badly At Love In Texas

The quiet ranches of Texas expected the possibility of the dreaded arrival of the New World screwworm coming in 2026. And when it did come, it involved a single calf in distress. Notably, the distress was warranted because something was eating it alive from the outside in. The nasty creature is back and agricultural authorities moved fast to contain it.

Dining On Living Flesh

While it sounds like an economic disaster, the element of a kind of biological horror engages inquiring minds. The screwworm doesn’t want dead flesh. It wants a living, breathing animal, per CBS News.

Unlike common maggots, nature’s dignified undertakers, the screwworm is a predator. Its body carries tiny, screw-like ridges. When it finds even a tick bite or a barbed-wire scratch, it bores straight into live tissue like a power drill with a grudge.

Controlling The Pest

Decades ago, Texas ranchers dreaded that tiny drill. Fortunately, the pest was controlled, then nearly erased. Now, with one infested calf, the whole sterile fly machinery of the USDA roars back to life: not with pesticides, but with radiation and insect sex.

Because here’s the strange irony: the female screwworm mates only once. A single, loyal, lifelong encounter. Scientists took that romantic fidelity and weaponized it.

They breed millions of male flies in labs, zap them with cobalt-60 or X-rays – Cold War leftovers – and release them into the wild. Then, the females lay eggs that never hatch.

So over the containment zone, low-flying planes now drop sterile males by the millions. It looks like a B-movie: Attack of the Atomic Flies. But it works.

A Bizzare Historical Career

The stranger history? In the 1950s, Texas scientists ran a facility they affectionately called “The Stinkhouse.” According to the Nautilus website, inside, ground beef, rabbit carcasses, and millions of screwworm maggots mounded together, feeding.

Researchers stood there in rubber aprons, breathing, no doubt, through clenched teeth, studying the life cycle of a parasite they planned to trick into suicide. They used nuclear technology, not to vaporize cities, but to save cows.

And somewhere in that sweaty, radioactive, meat-reeking irony, you realize: we sterilized an insect’s wedding night using the bones of the Cold War.

Last Year’s Warning

A year ago, KHOU 11 reported that Texas officals warned folks to be aware of a possible return of the  New World screwworm. The warning came after a new outbreak in Mexico.

The news anchor said, “…these larvae, these screw worms are flesh eating and while they mostly target livestock, they could also look for you…right.” And they are correct about that, per the American Society of Microbiology.
