Just one fly can lay up to 300 eggs at a time and is drawn "to the odor of a wound or natural opening on a live, warm-blooded animal."

A parasitic worm eradicated in the United States nearly 60 years ago could be threatening a comeback, Texas wildlife officials warn. The New World Screwworm was recently detected in Mexico, and the Texas Department of Parks and Wildlife is asking people in South Texas to watch out for animals affected by the screwworms.

The flesh-eating fly larvae, which were recently detected in Mexico, were declared eradicated from Texas in the 1960s.

South Texas hunters and outdoor enthusiasts will need to practice caution and monitor animals potentially affected by the New World Screwworm disease.

The Texas Parks and Wildlife said the screwworm was found in a cow at an inspection checkpoint in the southern Mexico State of Chiapas.

Texas wildlife officials are on the lookout for a flesh-devouring fly larvae known as the “Man-eater” after cases of the sickening vermin were recorded in Mexico.

The Texas Parks and Wildlife Department sent out an advisory warning hunters, livestock owners, and outdoorsy folks near the southern border to watch out for a flesh-eating parasite known as the New World Screwworm.

The screwworm can be devastating to crops and livestock, as it can cause serious, often fatal damage to living things.
