Will the trees in my yard or woodlot die once the leaves are completely chewed off by the gypsy moth?
Most trees survive, but survival depends on tree vigor before defoliation and the species of tree being attacked. Healthy, vigorous trees are generally able to withstand two or three years of heavy feeding by the gypsy moth. However, yard trees that are weakened by old age, drought, competition from other trees, or insects and diseases may die after one defoliation. In addition, coniferous trees, such as pine or spruce, cannot produce new needles after defoliation. Thus complete defoliation by gypsy moth may kill these trees.
