Yes, Talstar works well for both the mature and the immature spider mites and can be used on spruce trees. Talstar provides optimal spider mite control when applied during spring to mid-summer. Higher application rates and/or more frequent treatments may be required for acceptable spider mite control during mid to late-summer. The addition of a surfactant or horticultural oil may increase the effectiveness of Talstar.
