Overview

  • Sid Miller announced that Swormlure-5 traps will be placed across South Texas and the U.S.–Mexico border to lure and kill adult screwworm flies.
  • The synthetic attractant mimics open-wound scents and has previously eliminated up to 90 percent of wild screwworm populations within weeks.
  • Trapping efforts will run alongside sterilized male fly releases and Dichlorvos applications to collapse remaining screwworm cohorts.
  • USDA continues monthly livestock import suspensions with Mexico following detections 370 miles south of the Texas border in July.
  • A newly funded $8.5 million production facility in South Texas will supply sterile flies for scheduled aerial drops beginning next July.
