New World Screwworm

The New World screwworm is back in the headlines, and for good reason. In this in depth conversation, Clayton Leonard sits down with wildlife biologist Macy Ledbetter to discuss what landowners, ranchers, and deer managers need to know. Screwworms are not like the common flies we're used to dealing with. Female flies lay eggs in open wounds, and once hatched, the larvae feed on living tissue. Left untreated, infestations can become severe and even fatal. One of the biggest concerns is this year's fawn crop. Newborn fawns are particularly vulnerable because of their size and limited ability to defend themselves. Adult deer can also be at risk from injuries sustained during everyday movement, fencing encounters, fighting, or other wounds that may go unnoticed. The discussion also covers livestock management and why ranchers running cattle should work closely with their veterinarians to maintain proper herd health programs. Treating wounds quickly and staying proactive can help reduce opportunities for infestation and limit the spread of the pest.
