Most of the chemicals in the systemics you mention are no longer available to homeowners and I cannot locate a suitable replacement for you. However, instead of treating with a systemic, why not simply hose the spruces off every few weeks during the summer months to dislodge and discourage the pests most common to spruces? I've used this method for years on my spruces and have never had a problem with mites or bagworms. I think it will work for you, too.
