I always keep a bottle of Ivermec. I started using it when needed some 20 years ago. Great for Demodex, lice and rosacea as well as ascaris and hookworms and Morgellons and now Covid. Good stuff.
Pill form? Paste?
We have tubes of the paste, that we keep in the barn.
I had severe, disabling case of Morgellons but did not know about it then. Never did go back to work.
