Go to Spider mites and their control with predators and read up on predatory mites.
They can help with your spider mite problems.
The best way to prevent spider mite infestation would be a proactive
approach, and release predatory mites before you have a problem....
Strawberry growers have been doing this for over 30 years...
Once you notice you have spider mites it can get very costly to control them.

Hope this helps.
