This video introduces the biology and behavior of the New World Screwworm, a parasite that affects warm-blooded animals by feeding on living tissue. You'll learn how infestations begin, why they’re dangerous to livestock and wildlife, and how the U.S. successfully controlled the pest in the past using sterile fly releases. With recent signs of reemergence, it’s important to stay informed and prepared.

In this update, we cover where screwworms have been detected recently and what that means for livestock owners wildlife and companion anion. Surveillance efforts are underway along the U.S.–Mexico border, and agencies are working to prevent further spread. We also highlight cases in animals and humans, and explain which animals are most at risk including calves, horses, and pets with open wounds. Early detection and reporting are key to protecting your herd and your community.

This video outlines the technologies and treatments being used to manage screwworm outbreaks. From sterile fly production to improved traps and emergency drug approvals, you'll see how science and coordination are helping reduce risk. We also discuss the importance of proper wound care and animal husbandry practices to prevent infestations.

Preparedness is essential for livestock owners, veterinarians, and producers. This video explains the steps being taken to monitor for screwworms, manage animal movement, and ensure business continuity. It also covers treatment protocols, permitting requirements, and how agencies are working together to keep animals and people safe. Knowing what to do before a case appears can make all the difference.
