Tent Caterpillars / Webworms
Description: Caterpillars that feed on a wide variety of trees and build “tents” or “webs” on tree branches.
Trees Affected: Most tree species, but prefer crabapple, cherry, birch, linden, and ash.
What to look for: Physical presence of webs or tents throughout the tree crown, skeletonized leaves, defoliated portions of trees, or feeding caterpillars.
Treatment Options: Insecticide applications if severe damage. Can hand pick or prune out infestations on smaller trees.
