How far into flower at this point? Spider Mites are a constant problem where I live so I really understand your frustration. If you've got several weeks left
Azamax is a safe option. If you're girls are heavily infested and/or the spider mites are naturally occurring, all you can hope to do is control them. I didn't check to see if you mentioned whether your girls are outdoor or not. If outdoor your they will likely get through to harvest with only a little loss in yield as long as you can keep the infestation to a minimum. I've got them all over my last outdoor plant and I'll give it a couple, maybe three,
Azamax applications to reduce the population till harvest. I don't panic about them anymore since I've rarely heard of them actually killing an outdoor plant of any decent sise.
To answer your original questions...
Spider Mites are fast moving and can travel up a 10'+ plant in less than an hour. They also parachute over great distances on their webs if there's any breese.
Here's some info from Penn State University Ag Deparment...
Life History
This pest overwinters as mature yellowish-orange females under bark or ground cover around the base of the host plant (most other species of spider mites overwinter as eggs on the host plant). After mating, females lay eggs on the underside of leaves at the rate of 2-6 a day. Each female may lay as many as 100 during her lifetime. Eggs hatch in 2-6 days into young mites. The young mites shed exoskeletons three times before becoming mature. Depending on weather conditions, a complete generation of this pest may be completed in 7-20 days. The various generations overlap and all stages can be found on most host plants during the summer months. There may be 10-15 generations completed a year in Pennsylvania. Hot dry weather favors the development of severe infestations of this pest.
