OMRI listed for organic gardening
AzaMax is a great pesticide to keep spider mites under control, though it has several drawbacks. It doesn't completely eradicate spider mites, is ineffective against broads and russets, it's expensive, and will taint the flavor of the flowers if used late into bloom. On the positive side, it's absolutely safe to mammals, it has a 90%+ kill rate on 2Spot spider mites, and it can be used right up till harvest in dire situations.
I used Azamax the 1st year I grew, switched to Triazicide because of it's 100% kill rate on everything and it's only $10 or less per bottle. It is not organic, but people don't generally realise that just because a pesticide is derived from a natural source doesn't mean it's any safer. Triazicide is actually safer than pyrethrin if accidentally ingested and is only considered "mildly toxic" to mammals. I'm only more careful with it because it's a sytemic that lingers quite some time.
My infestation. 2Spot spider mites after the chop. 10's of thousands of them. As the day warmed up they congregated into these masses that looked to almost move like an orange liquid. This is the biggest infestation I've ever had. I misted them with hydrogen peroxide to thin out their numbers and it melted their webs into plastic looking sheets. They hit so late in the flower cycle there wasn't much that could be done about it. I kept most of the plants in tact to draw them out of the flowers and up onto the bases or into the popcorn. I turned off my fans and closed up the shed to cook them out. That made the majority of them leave the plants.
