Spider mites-best to remove infested plants to save the others?

i have two sativas in flower along with 5 other indicas , the two sativas have been badly damaged by the spider mites but the others seem to not have been affected too badly at all. at what point is it best to just remove the infected plants. we have used various pesticides for edible vegetable plants and have knocked back the spider mites significantly but they are coming back. every leaf on the infected plants are significantly spotted with yellow marks and are drying up with visible mites and their webs on top and under the leaves.

mighty wash and the best sprayer you can afford, I see location as colorado. mites are a bitch here. I use an airless paint sprayer no matter what I spray . I stick with mighty wash and a pyrethrin based insecticide.this summer I'm putting the atomist on a cycle timer and loading it up with riptide. Mites are serious pests here .

as far as moving the plants I wouldn't know why , just keep spraying . mighty wash is very safe and affective.

Mites are serious pests everywhere..........
