RALEIGH, N.C.–Eastern tent caterpillars have well established nests in central NC. They favor cherry trees and often become a concern for homeowners. Concern is largely because they are noticeable.
Of course trees are covered in tiny pests like scales that people aren’t concerned about because they are small and hard to see. But that’s another story. In most cases in home landscapes no . The best action to recommend is pruning the nest out of the tree or jabbing it full of holes so birds and predators can access the larvae.
