New World Screwworm (NWS)
The New World screwworm (NWS) is a type of fly whose larvae (maggots) feed exclusively on the living tissues of warm-blooded animals. UF/IFAS is monitoring the spread of NWS and providing resources for livestock managers, veterinarians, wildlife officials, and community leaders across Florida. Please go to the UF/IFAS New World Screwworm website for access to materials and science-based resources that may not be available on this site.
Any suspected cases of New World screwworm in Florida should be immediately reported to FDACS.
