Pests and potential problems
Red spruce has several insect enemies, the most important being spruce budworm. Budworm damage may be heavy in stands that contain a large percentage of balsam fir. Some stands of red spruce may be susceptible to damage by the eastern spruce beetle, European spruce sawfly and yellow-headed spruce sawfly. Disease problems are minor in management of red spruce.
The overall health of red spruce stands seems to be declining due to pollution factors. Weakened trees are more susceptible to insects and disease.
