Harvested buds with spider mites - are they dead?

So I have a spider mite problem growing in my closet. I harvested the worst affected plant, and neem sprayed the rest.
I hung the harvested plant in the shed for 5 days. Now I'm concerned about bringing it back into my room for bottling.
(A tiny bit concerned about smoking spider mites too, it would be nice to remove them.)

Does drying the buds kill the spider mites?
Does pinning the buds to the bottom of a bucket of water, drown spider mites? Maybe even remove most?

You should have not used neem late in flower. Or harvested your plant yet. You could have used mighty wash it can be used all the way up to harvest.

I went through this Take little baking powder and a little lemon juice warm water and gently wash buds. Then soak/rinse buds in room temp water to do final rinse. Lay buds on a paper towel and gently remove excess water and hang to dry.

All the remaining plants, that I used neem on, were very early in flower
Awesome, I remember seeing some sort of lemon bud wash on Youtube once, and was wondering what to do!
