You can use Abamectin 0.15 EC for control of spruce spider mites and other mites listed on the product label. You would use 4 oz per 100 gallons of water as a topical spray (0.04 fl oz or 1.18 mL per gal). Imidacloprid products such as Criterion G will not aide in treatment of mites, but will treat other listed insects.
