How do I keep spider mites away from my houseplants?
Spider mites don't like high humidity but thrive when the air is warm and dry. To prevent them, provide a moister atmosphere for your plants. This might mean giving the plants a shower once or twice a week. To combat the pests, use insecticidal soap or a houseplant insecticide that specifically says it will kill spider mites. Spray the upper and lower surfaces of the leaves, and repeat the spray according to label directions.
