Q: A friend in coastal GA has a spider mite infestation on her citrus trees. She has tried liquid Sevin and insecticidal soap. Is this effective?
A: Using Sevin is an excellent way to get MORE spider mites. This insecticide kills all of the beneficial insects that eat mites and partially control them. A suffocating oil miticide/insecticide would be more effective. Try neem oil or any other horticultural oil. Spray every three weeks.
