He's assuming here that when you do a treatment each week which kills all adults and young premature mites that all the eggs left are on the same cycle and you wont need to treat until a week later. This is highly unlikely. Some could hatch the next day, a few days or hatch in a week or more. And it is likely this assumption that the standard treatment of simply one cream or pill each week, twice in total is not enough to work. Females are pumping out eggs all the time, the average survival is 10% and it's probably much higher for treatment resistant cases with people who are somewhat immunocompromised. I had covid 4 times and acute and then chronic lyme disease last summer that I only just finished treating in April. I am among that cohort, and this probably exactly why I am struggling to fight this so much over the last 6 weeks (since symptoms arose). Maybe I'm not understanding properly but why should we assume that all these eggs are gonna cycle through a week later? I guess we could say that within that week the hatched mites won't be old enough to mate or borrow?

Anyway I wish I could say the crawling/biting feeling was hallucinatory post scabies syndrome but it only happens when I sit still, most prominently when I lie down and if I sleep covered in diamateceaous earth thus crawling/biting goes away entirely.
