Only the eastern hemlock borer, a flathead insect, is an important pest for this species. Its presence is evidenced by the mining of the bark of trees, both living and dead. Loopers, the little larvae that make haste slowly by forming their bodies in a three-quarter-inch contortion as they inch their way up a twig, commonly feed on the foliage. Some call the larvae inchworms.
The rots caused by several species of wood-attacking fungi are also found in these trees. Seldom do they pose a serious menace to the forest.
