Answer: Spider mites can sometimes be controlled by a twice a week washing with a spray of tepid water. Or, an insecticidal soap such as you have been using can be applied (and reapplied) per the label instructions. Be sure to wash or spray all sides of the leaves and stems. Raising the humidity level around the plant can also help. You might check back with your retailer as well. I'm sorry you are having trouble with your plant.
