Someone said the pinworms are "less." That is not encouraging because it means they are still there and they multiply. Pinworms are associated with appendicitis, not something to mess with.
I would try the cayenne pepper challenge test, not when you are on diatomaceous earth or any paracides. See if those "white rice" show up, or the "seseme seeds" or "cut nuts". I think then you will see how accurate those DNA tests are.
