I'm currently harvesting seeded budz that also have mites and came up with this little trick to suck the little bastards down to mite hell!
Found some screen with a mesh about 4x as big as window screen and used electrical tape to fix it over the end of the crevice tool for the vacuum. Just chop off a branch and lightly bump the buds around on it to get rid of most of them. All but the best colas will be made into oil and vac-sucked thru a lab filter much finer than a coffee filter to make into hash with kief from older crops.

These are the little f'ers I'm dealing with.
Took this pic with my new 40-1000x USB scope on a tripod. You can see the reflection of the 8 little LED lights around the lens on the mite egg on the right.
