How to Kill Red Spider Mites in the Garden and on the Rock Wall
Red spider mites are common pests in gardens and on plants growing on rock walls. In fact, small crevices in rock walls offer red spider mites perfect hiding places from spray insecticides. It is important for gardeners to reduce the red spider mite population, because these pests cause discoloration, defoliation, scorched leaves, and death to plants. Using the right type of insecticide and taking special consideration of the areas in a rock wall where red spider mites can hide, will help you prevent damage to your ornamental plants.
