Once you harvest you really don't have many options other than budwashing. If you already did that then, as was mentioned, you get to enjoy your regional flavors!

Just for fun you can put them under the loupe and fry them with your dab torch while you smoke them and watch them fry!!
DIE MENDO MITE, DIE!!!!!
For most of my bug eradication needs I like to use a product called
Azamax. It is OMRI certified and is a
Neem oil derivative. Works very well in controlling bug populations but before I go there, depending on how bad the infestation is, I'll start with an insecticidal soap to see if that takes care of them.
Azamax is my nuclear option.
@Organic13 - Unless they are everywhere I wouldn't worry too much. Every day we eat rat feces in our processed foods. A little mite with your smoke is fine.
Try some indoor growing. Much easier in regard to controlling your environment but you have to follow certain cleanliness protocols like not bringing in any outdoor plant material into your indoor gardens along with not going into your tent right after you came in from the garden.
I have a set of canvas coveralls I wear when I open my tent to keep any hitchhikers from infecting my gardens. I know it sounds like overkill but I learned all this working in licensed grow ops. I thought it was overkill also but I haven't had a bug problem in over 10 years.
