New houseplants should be isolated from other houseplants until you’re sure that no spider mites are present. I often wash new nursery plants in the sink before I repot them as insurance against outside pests.
Make sure your garden is mulched to retain moisture, and use an automated irrigation system to provide consistent water.
This keeps them from spreading to the rest of the plant (as well as nearby plants), but is only effective if you catch them early.
Repeat every day or every other day to keep their numbers down; this also keeps the environment cooler and wetter (two things they don’t like).
Make sure you use food-grade diatomaceous earth (not the industrial-grade DE found in pool filters) and wear a mask if you’re sensitive to dust.
