La osa, que andaba con sus crías, fue reportada por ciudadanos que notaron que la madre no se veía muy bien de la cara. Personal de Parques y Vida Silvestre de Nuevo León (PVSNL) procedió a la captura para que el Laboratorio de Entomología de la Facultad de Ciencias Biológicas confirmara que, efectivamente, tenía una infección por Cochliomyia hominivorax.
Para solucionar el problema, las autoridades organizaron un retiro sanitario de tres semanas. El tratamiento incluyó limpieza profunda de heridas, antibióticos, analgésicos y una dieta controlada, mientras la osa y sus oseznos permanecían en aislamiento.
El Servicio Nacional de Sanidad, Inocuidad y Calidad Agroalimentaria (Senasica) reporta que el gusano barrenador del ganado ya suma 1,907 casos activos en México, infectando a todo lo que se mueva: vacas, perros, gatos, ceros y hasta humanos.
El problema es tan serio que México y Estados Unidos suspendieron el intercambio de animales vivos para evitar que las larva se paseen own the way to the noroeste del país.
