The article you referred to (and I've seen linked elsewhere in this thread) is about "regular" screwworm (Chrysomya bezziana). The recent outbreak is of New World Screwworm (Cochliomyia hominivorax). The article I've linked suggests that it is much harder to kill than regular screwworm (29% of calves developed myiasis even when treated with ivermectin).
