BRYAN, Texas (KBTX) - Multiple New World Screwworm cases were detected last week in South Texas.

While work is underway for more mass production of sterile male flies to spearhead the eradication effort, ranchers are scrambling to keep the infestation from turning into an economic disaster."There's no magic concoction that's going to fix this. This sterile insect technique or those sterile flies are the solution going forward," said Karl Harborth, a Texas A&M AgriLife Extension livestock specialist in Corpus Christi.

"Once we have enough of those, we can probably have a little better handle on stopping it. And they're on the way, but they're not here yet."Texas A&M AgriLife Extension professor Ron Gill said there's a playbook in place that the USDA and the Texas Animal Health Commission have been working on for a long time."We can check our cows, we can check our sheep and goats, and horses and dogs and cats, and monitor them. We recommend that you need to be seeing them every two to three days," Harborth said.
