What to expect with mites

[Vypyrz]

So my question is, what should I expect moving forward here. Will he continue to soak even if the mites are gone? How often should I treat him as the spray doesn't specify. I'll continue to research this online but I figure there is no better source of information than this group here.

For starters, what kind of spray are you using?

Edit* I just noticed you also have a boa. Go ahead and start checking it as well. Mites will migrate or hitch a ride..
