This is fairly common problem with Dwarf Alberta Spruce. First make sure you are watering enough but not over watering, that your soil pH is 5.5 - 7.0 and that the plants are in full sun (6+ hours per day). If the cultural conditions aren't right you will have a tough time keeping the trees healthy in the long run. The organic solutions include insecticidal soaps, dormant oil and summer oil.

Thank goodness for your new growth.

I think the idea of spraying with insecticidal soap is dead-on. Those spider mites are not a good thing. And the soap won't harm the environment, either. It just kind of dissolves the spider mites away.
