SOCORRO, TX (KVIA) – Crews in El Paso’s lower valley will begin a major cleanup effort today to tackle the unusual red flour beetle infestation. Pecan shells have been identified as the primary source of food for the beetles, which is what led thousands of them into homes. ABC-7 spoke to Dr. Robert Puckett, an extension entomologist at Texas A&M University in College Station, who says the pecan shell removal is crucial step toward relief.
