Texas’ Sid Miller deploys a new tool against New World Screwworm

His department will be using a synthetic bait called “Swormlure Five,” which is engineered to smell like an open wound, attracting Screwworm flies to the bait

Texas Ag Commissioner Sid Miller is continuing the fight to keep New World Screwworm out of the United States. He recently announced new steps he is taking in the Lone Star State.

His department will be using a synthetic bait called “Swormlure Five,” which is engineered to smell like an open wound, attracting Screwworm flies to the bait. Once they reach the trap, they die.

Miller says prior tests using the new bait took out 90 percent of the flies within two to four weeks. He says the remaining flies are wiped out using sterile male flies in the same area.

The project with this new bait is an effort alongside USDA. They are also working with the Mexican government to do their part. Miller says, “We’ve beaten this before, and we’ll do it again,” which is in reference to when the pest was found in U.S. herds in the 1970s. He adds it will take all hands on deck this time around to keep it outside U.S. borders.
