^Yup, and no guarantee that it'd work on these particular parasites either.
And yes, you're totally right that that stuff doesn't work. Did DD's hair, left on the full 10 minutes (says NOT to do more) and the critters were still moving... *shudder* and that stinking comb might catch the bugs, but it doesn't do doodly for the nits that are superglued on. And the "loosening gel" didn't work for doodly either.
Definitely not worth the money they charge for the product... even they admit that it fails, OFTEN, right there on the box.
Much better to try alternate (and overlapping) methods.
