Coretect Tree & Shrub Tablets is not labeled for any type of worm, it is a great one for plant sucking pests. Tempo Sc Ultra is labeled for bud worms and should do a great job for you when used as directed. We do recommend testing the product on one small area of the tree before broadcasting on the entire tree because spruce are known to loose their color very easily from insecticide applications.
