Summary

This article chronicles the devastating impact of screwworms on livestock in the American South and Southwest, and the scientific breakthrough that led to their eradication. It describes how screwworms, which lay eggs in open wounds of warm-blooded animals, caused immense suffering and economic damage for generations. The piece details the methodical northward march of these pests each spring, their destructive feeding habits, and the eventual development of the sterile insect technique (SIT) — a revolutionary biological control method that released sterilized male flies to disrupt reproduction. The article explores the scientific, logistical, and human dimensions of this eradication campaign, which stands as one of the great success stories in veterinary entomology and agricultural pest control.

Every spring, as sure as the seasons, and for generations unknown, screwworms began their annual march northward from their overwintering sanctuaries in Mexico and South Texas.
