Answer: I'm only making an educated guess without seeing the pest, but I'll bet it's Spruce budworm. These larvae attack the foliage and buds of spruce and can be controlled with Bt (Bacillus thuringiensis) in early spring when the larvae begin to feed on old needles and before they enter buds. June to July applications will control larvae on new growth. To make certain that's the pest you're dealing with, and to learn about other control measures, be sure to take a sample to your local Cooperative Extension office. Phone (740) 368-1925. Good luck with your spruce!
