Is ivermectin not an option? My fat pet rat got mites and was miserable, itchy and too painful to scratch. One grain of rice dose from the infamous horse tube cleared him right up.

  Ivermectin liquid "pour-on" is poured along the backbone of cattle (just as you do in cats and dogs with flea medications).

    The study I linked to showing the effectiveness of Ivermectin was only done subcutaneously. I did not find a study on the effectiveness of non-subcutaneous Ivermectin treatments on screw worms. Given one of the areas they focused on the study is the scrotal area post castration, I don't expect that a pour on would cover that area well enough to be an effective treatment. Happy to read other studies if you have them showing otherwise.

      You can use it topically but typically it's an oral dose.

        There are injectable and transdermal (pour-on and ear tag) forms for cattle and pigs. I'm not aware of an oral formulation for food animals, even though that's pretty common for horses.

  https://pubmed.ncbi.nlm.nih.gov/9403981/ https://pubmed.ncbi.nlm.nih.gov/9403981/ 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).

    Googling "Cochliomyia hominivorax and ivermectin" yields "Ivermectin can be an effective treatment for myiasis, a condition caused by the larvae of certain dipterous flies, including Cochliomyia hominivorax (the New World screwworm). Studies have shown that ivermectin, when administered orally or topically, can help eliminate the larvae and reduce the severity of the infestation, especially in cases of orbital or oral myiasis. "

  There’s also resistance to worry about if used widely.

You still need to remove them, otherwise you have decomposing maggots in an infected would, which is a great way of killing whatever you were trying to save.
